Hedging with the AMD Perpetual: Sizing, Margin and Funding

Owning a stock after a big run brings a pleasant problem with a sharp edge. The gain is real, but one bad earnings night or a sell-off across the sector can take a large part of it back. Selling protects it, but it also means giving up shares you meant to keep.

A hedge is the usual answer: a second position that gains when the first one loses, so the two together move far less than either one alone. If you hold a stock, a short hedge sells a futures contract on the same asset, so a fall in the share price shows up as a matching gain on the contract (source: AnalystPrep, hedging strategies using futures). The best-known other tool, a put option, costs a premium that is lost if the stock holds up.

A perpetual contract on one company's shares can play the futures role with no expiry date to roll. You sell it in the same size as the shares you own and keep it for as long as the worry lasts, then close it. What it asks for in return is margin of its own, and a payment called funding that runs every eight hours.

BloFin lists that contract for AMD as the AMDUSDT Perpetual, and AMD holders have rarely had more to protect. The stock closed at a record $649.42 on October 6, 2026, about three times its $210.21 close on April 1, after trading as high as $658.52 that day (source: Yahoo Finance, AMD price history).

What is hedging with the AMD perpetual?

Hedging with the AMD perpetual means opening a short AMDUSDT position on BloFin that matches the AMD shares you hold elsewhere, so a fall in the share price is offset by a gain on the short. The shares stay at your broker, and the short needs USDT margin of its own on BloFin.

The offset works because both positions follow the same price in opposite directions. Say you hold 10 AMD shares, worth $6,494.20 at the October 6 close. On BloFin, each AMDUSDT contract is 0.01 AMD (source: BloFin, AMDUSDT listing notice). A short of 10 AMD is therefore 1,000 contracts, and the smallest order is a single contract of 0.01 AMD (source: BloFin, AMDUSDT contract information). If AMD then falls 10%, the shares lose about $649 and the short gains about 649 USDT. If AMD rises 10%, the shares gain about $649 and the short loses about 649 USDT. Before funding and fees, the two together barely move, worked out.

That is both the point and the price of a full hedge. It holds your position near the value it had when you opened the short. You are covered against a fall, and you give up the gain from a rise.

Hedging is also different from selling. Your shares stay in your brokerage account with every right that comes with them. The perpetual gives you no stake in AMD, because BloFin's stock futures track the share price without giving you any ownership of the shares (source: BloFin stock futures notice, April 21, 2026). When you close the short, you are back to holding plain AMD shares, with nothing to buy back at your broker.

A hedge suits a set period you are worried about, such as the days around an earnings report, and trading AMD around earnings looks at that week from the trader's side. A hedge with no end date in mind is closer to a sale with margin and funding attached.

The contract's live price, mark price and current funding rate are on the AMDUSDT Perpetual page.

How to size an AMD hedge

Size an AMD hedge by shorting as much AMD as you hold in shares, so 10 shares call for a 10 AMD short. At 0.01 AMD a contract, that full hedge is 1,000 contracts, and a half hedge of 5 AMD is 500 contracts. The short's value then rises and falls with the shares' value, one AMD for one share.

BloFin's order form asks for the amount in AMD rather than in contracts, so that full hedge is entered as 10 AMD (source: BloFin, AMDUSDT Perpetual page). Typing the contract count into the same field would ask for a short 100 times the size you meant.

At the October 6 close of $649.42, the hedge for a few common holdings looks like this. The margin column shows what BloFin holds against the short at 1x and 2x, worked out as the hedge's value over the leverage (source: BloFin Help Center, margin mechanism).

Two limits shape larger hedges. BloFin caps a single market order at 200 AMD and a single limit order at 2,000 AMD (source: BloFin, AMDUSDT contract information). So hedging 300 shares at market takes two orders. Size also changes the maintenance margin, the share of a position's value BloFin needs you to keep as margin. It is 2.50% for positions up to 200 AMD and 3.33% from 200.01 AMD to 1,000 AMD (source: BloFin, AMDUSDT position tiers). Each higher step is listed in the AMD perpetual's contract specs.

A partial hedge is a deliberate choice. Shorting half your share count leaves half the move with you in either direction, which suits a holder who wants to soften a fall without capping the whole upside. Whatever the size, the order itself is an ordinary sell on the perpetual, with the amount entered in AMD.

Margin and liquidation risk on an AMD hedge

An AMD hedge needs USDT margin of its own, because shares held at a broker are not collateral on BloFin. In a rally the short loses USDT on BloFin while the matching gain sits in your brokerage account, so a short with too little margin can be liquidated and leave the shares unhedged.

On paper the two positions cancel. In practice the gain and the loss land in different accounts, and only the BloFin side has a liquidation price. BloFin liquidates a position once the margin left in it, counting its unrealized profit or loss, is no more than the maintenance margin and the fee for closing it. It may cut part of the position or all of it (source: BloFin Help Center, Forced Liquidation Rules). How that forced exit works in general is set out in leverage and liquidation.

BloFin publishes the formula for a short's liquidation price in isolated margin. Take the margin, add the position size multiplied by the entry price, and divide that total by the position size multiplied by one, plus the maintenance margin rate, plus the fee rate (source: BloFin Help Center, Liquidation Price Calculation). The first-tier maintenance margin rate is 2.50% (source: BloFin, AMDUSDT position tiers). For the fee rate, the example in BloFin's liquidation rules plugs in 0.06% (source: BloFin Help Center, Forced Liquidation Rules). With both rates, a 10-share hedge opened at 649.42 USDT with 2x leverage is liquidated near 949.81 USDT, after a rise of about 46.3%, worked out. Higher leverage pulls that price much closer, as sizing an AMD perpetual position shows level by level.

AMD's recent rallies show why the distance matters. The stock rose 9.95% from its September 18 close to its September 21 close, and 18.61% from its May 5 close to its May 6 close (source: Yahoo Finance, AMD price history). That May 6 session followed AMD's first-quarter report after the close on May 5 (source: AMD investor relations calendar). Say you hold a short with little margin, and a rally like that closes it before reversing the next week. The shares give the gain back, and the short that would have covered the fall is gone, along with its margin. If the liquidation comes outside regular weekday trading hours, BloFin may accept only orders that reduce a position (source: BloFin stock futures notice, April 21, 2026). A new short may then have to wait for the next regular session.

A working hedge can also be closed for you. When the insurance fund behind a contract runs short or drops fast, BloFin's auto-deleveraging matches the shortfall against traders holding winning positions on the opposite side, closing them at the mark price. The ranking puts a higher return on margin first (source: BloFin Help Center, auto-deleveraging). A hedge at 1x or 2x earns a small return on its margin, so it usually ranks behind more highly leveraged winners in that queue.

Keeping spare USDT for an AMD hedge

Spare USDT in your futures account is what keeps a hedge alive through a rally. Adding margin to an isolated position moves its liquidation price further away, so a holder who keeps extra USDT ready can respond to a sharp rise instead of watching the short get closed.

BloFin lists added or removed margin as one of the reasons an isolated position's estimated liquidation price changes (source: BloFin Help Center, Forced Liquidation Rules). The formula shows how far it moves. Take the same 10-share hedge at 2x with 3,247.10 USDT of margin, liquidated near 949.81 USDT. Add 1,000 USDT and the liquidation price rises to about 1,047.32 USDT, a rise of about 61.3% from entry, worked out.

Timing matters as much as the amount. Once the mark price reaches the liquidation price, BloFin stops accepting margin changes and orders on that position (source: BloFin Help Center, Forced Liquidation Rules). Margin has to go in while there is still room. The mark price is the one BloFin watches for liquidation, and it keeps moving after the regular session closes.

Cross margin is the other way to back a hedge. In cross margin, every USDT in the futures account supports your positions, and BloFin notes that the mode is often used for hedging (source: BloFin Help Center, margin mechanism). The same page warns that in an extreme move the whole account balance can go to zero. Isolated margin caps the loss at the margin set aside for that one position. The two modes are compared in margin requirements on the AMD perpetual.

Funding on an AMD hedge

A short AMD hedge receives funding when the AMDUSDT rate is positive and pays it when the rate is negative, every eight hours. Over the 90 days to October 6, 2026, AMDUSDT's 270 settlements added up to +0.7405%, so a 10-share hedge at its October 6 value would have received about 48 USDT (source: BloFin, AMDUSDT funding history).

Each payment equals the hedge's value times the rate. A positive rate moves money from longs to shorts, and a negative rate moves it from shorts to longs (source: BloFin Help Center, funding rates). That makes funding a running cost or a small income for the hedge, on top of the price offset, the same trade-off behind all crypto funding rates.

Say you hold the 10-share hedge, a 6,494.20 USDT short. Most AMDUSDT settlements have been tiny: of the 270 in those 90 days, 146 were positive, 116 negative and 8 zero, and the median was +0.0003% (source: BloFin, AMDUSDT funding history). The most your short took in from one settlement was about 4.02 USDT, at +0.0619% at 12AM UTC on September 21, 2026. The largest single payment was about 3.37 USDT, at −0.0519% at 8AM UTC on September 28, worked out. The way AMDUSDT's rate is calculated is in the AMD perpetual funding rate explained.

Since the contract listed in May, its 459 settlements have summed to +4.6575%, with the largest single rate, +0.4192%, in its first week (source: BloFin, AMDUSDT funding history).

Weekends deserve their own look. Between the Friday close and the Monday open, eight settlements fall while the share market's regular session is closed. Of the 22 weekends since listing, the eight settlements added up to a positive rate on 12 and a negative rate on 10 (source: BloFin, AMDUSDT funding history). The weekend of September 26 to 28 summed to −0.0902%, which cost your 6,494.20 USDT short about 5.86 USDT, worked out.

Funding also moves the liquidation price. In isolated margin, paying or collecting funding changes the margin behind the position, and BloFin lists it as a reason the estimated liquidation price shifts (source: BloFin Help Center, Forced Liquidation Rules). A short that pays for several weeks in a row slowly loses room, which is one more reason to keep spare USDT.

Reduce-only hours, weekends and basis on an AMD hedge

BloFin may limit its stock futures to reduce-only orders outside regular weekday trading hours, and on weekends and market holidays. A hedge can then be cut or closed but not opened or enlarged. Set it up between 1.30PM and 8PM UTC on a weekday while US daylight saving time lasts (source: BloFin stock futures notice, April 21, 2026).

With reduce-only switched on, an order can make an existing position smaller or close it, and it never adds to that position or opens the opposite side (source: BloFin Help Center, Reduce Only). For a hedger, that rule cuts both ways. You can cut protection at any hour, but outside regular hours BloFin may not let you add it. Those hours shift with daylight saving time: from November 1, 2026, the first Sunday in November, they run from 2.30PM to 9PM UTC (source: BloFin stock futures notice, April 21, 2026). The same notice lists Thanksgiving, November 26, as a full-day closure. The full schedule is part of the AMD perpetual's trading hours.

The perpetual keeps trading outside the regular session, while your shares trade only in thinner after-hours or pre-market sessions, or not at all on weekends, until the next regular session. That gap is where basis comes from. Basis risk is the chance that a futures contract and the asset it hedges stop moving in step (source: AnalystPrep, hedging strategies using futures). Over the weekend of October 3 and 4, 2026, AMDUSDT traded as high as 643.14 USDT in the hour from 1AM UTC on Monday, October 5 (source: BloFin, AMDUSDT price chart). That was about 1.5% above AMD's Friday close of $633.91, worked out. A 10-share hedge opened at Friday's close would have shown a loss of about 92 USDT at that hour, with no regular-session price for the shares to offset it until Monday.

By the time the shares had traded a full session, the two had come back together. At 4PM ET on October 5, AMDUSDT stood at 631.70 USDT (source: BloFin, AMDUSDT price chart). AMD's own close that day was $631.75 (source: Yahoo Finance, AMD price history). That is how the weekend played out: the gap between the hedge and the shares opened while the regular session was closed and narrowed once it reopened. The danger is a leveraged short that hits its liquidation price while the gap is open, which AMD perpetual overnight and weekend gap risk covers in detail.

Hedging NVDAX or a chip-heavy portfolio with the AMD perpetual

The AMD perpetual is a close hedge only for AMD itself. For an Nvidia holding, the direct hedge is a short on Nvidia's own perpetual. Over the 66 sessions to October 6, 2026, AMD's daily moves had a correlation of 0.374 with Nvidia's, so an AMD short would have removed about 14% of the variance of Nvidia's daily returns.

Those figures come from the standard way to size a cross hedge, one built from a different asset than the one you hold. The hedge ratio is the correlation between the two assets' price changes, times the holding's volatility, divided by the hedge's volatility. The share of the holding's daily variance the hedge removes is the correlation squared (source: AnalystPrep, hedging strategies using futures). Variance measures how widely daily returns spread around their average. From daily closes between July 2 and October 6, Nvidia's swings measured 2.38% a day (source: Yahoo Finance, Nvidia price history). AMD's measured 4.12% a day over the same sessions (source: Yahoo Finance, AMD price history). The ratio comes to 0.374 × 2.38 ÷ 4.12, or about 0.216, so 1,000 USDT of Nvidia calls for an AMD short of about 216 USDT, worked out.

BloFin lists Nvidia both as NVDAX/USDT Spot, a tokenized share, and as the NVDAUSDT Perpetual. An NVDAX holder can therefore hedge with a short of the same size on the same company.

Hedging NVDA with the perpetual works through that direct route.

For a portfolio spread across many chip stocks, a sector contract can stand in for several single-stock shorts. BloFin's SMHUSDT Perpetual follows the VanEck Semiconductor ETF (SMH), the contract's underlying asset (source: BloFin, SMHUSDT listing notice). The fund held 26 chip stocks on October 3, 2026, with Nvidia the largest at 19.14% and AMD at 5.57% (source: Stock Analysis, SMH holdings). Owning such a fund outright, in place of the AMD contract, adds chip exposure rather than hedging it.

BloFin listed the AMDUSDT Perpetual on May 6, 2026 (source: BloFin, AMDUSDT listing notice). The SMH contract followed on July 30, 2026 (source: BloFin, SMHUSDT listing notice). Both listings fall inside the period from April 2 to October 6, so the share of daily variance each short would have removed comes from the shares' and the fund's own closes (source: Yahoo Finance, SMH price history).

On those closes, a sector-fund short would have hedged the mixed portfolio better from July to October, and an AMD short better from April to July. AMD's swings are so large that they drive most of a half-and-half portfolio's moves, which is why a short on AMD alone covered most of it.

Why the correlation behind a chip hedge changes

Correlation measures the past, and between chip stocks it moves a lot from one quarter to the next. AMD and Nvidia's daily correlation was 0.495 from April 2 to July 2, 2026 and 0.374 from July 6 to October 6. The hedge ratio for an Nvidia holding moved with it, from 0.238 to 0.216, worked out.

Shorter windows swing further. Measured over 20 sessions at a time, the AMD-Nvidia correlation fell as low as 0.07 in the 20 sessions to June 4. It rose as high as 0.87 in the 20 sessions to July 6, worked out from the same closes (source: Yahoo Finance, Nvidia price history). Single days explain why. On August 5, 2026, AMD fell 7.04% while Nvidia rose 3.43% (source: Yahoo Finance, AMD price history). That was the session after AMD's second-quarter report after the close on August 4 (source: AMD investor relations calendar). On August 27, Nvidia rose 8.74% while AMD slipped 0.89% (source: Yahoo Finance, Nvidia price history). On days driven by one company's own news, a hedge built from the other stock can work in reverse.

The hedge-ratio method expects exactly this. Its inputs come from past price changes, measured over a period that matches the life of the hedge (source: AnalystPrep, hedging strategies using futures). In practice, measure daily returns, never price levels, over a window close to the time you plan to hold the hedge. Then measure again before you rely on the ratio. The reasons AMD and Nvidia sometimes move together and sometimes apart are laid out in what moves AMD stock.

AMD and Nvidia perpetual pair trade

An AMD and Nvidia pair trade holds one perpetual long and the other short in equal dollar amounts, so it gains or loses on the gap between the two stocks' returns. The part of the move the two stocks share cancels out, and funding is paid or received on both legs at every settlement.

Pair trades are normally built from stocks that move closely together. A classic pair picks two similar securities with a high positive correlation, then shorts the one that looks expensive and buys the one that looks cheap (source: CFI, pairs trading). AMD and Nvidia came in at a correlation of 0.374 from July to October. A pair of the two is therefore a view on AMD against Nvidia, with large swings in both directions.

The record from July 2 to October 6 shows both sides of that. Say you held 5,000 USDT long Nvidia and 5,000 USDT short AMD. Nvidia rose 22.79% over those three months (source: Yahoo Finance, Nvidia price history). AMD rose 25.41% over the same months (source: Yahoo Finance, AMD price history). The pair therefore lost about 131 USDT before funding and fees, worked out. Along the way, single days moved it by hundreds: about +524 USDT on August 5 and about +481 USDT on August 27, worked out. The same days would have cost a pair facing the other way the same amounts.

Funding adds a second, smaller line. Over the 90 days to October 6, AMDUSDT's settlements summed to +0.7405% (source: BloFin, AMDUSDT funding history). NVDAUSDT's summed to +0.2007% over the same 90 days (source: BloFin, NVDAUSDT funding history). Both were positive, so the short AMD leg received about 37 USDT and the long Nvidia leg paid about 10 USDT. That is a net of about 27 USDT received, worked out on constant position values. Turn the pair around and that net becomes a cost.

Margin mode decides how the two legs support each other. In cross margin, the gains and losses of all positions in the account are counted together (source: BloFin Help Center, margin mechanism). A rising long can then carry a losing short. In isolated margin, each leg has its own liquidation price, and a sharp jump in AMD can close the short while the Nvidia gain sits in a different position.

Checking an AMD hedge before you open it

Before you open an AMD hedge, match the short's amount in AMD to your shares, choose low leverage, keep spare USDT, and open it during regular weekday hours. Then check the funding rate and the calendar, and decide in advance what will make you close it.

Each check takes a minute and covers a way a hedge can fail.

• Enter your share count as the amount in AMD, which equals 100 contracts a share, and decide whether you want a full or a partial hedge.

• Pick leverage of 1x or 2x: at 2x a 10-share hedge is liquidated after a rise of about 46.3%, worked out from BloFin's formula, and higher leverage brings that much closer.

• Keep spare USDT in the futures account, because margin can only be added while the mark price is clear of the liquidation price.

• Open the short between 1.30PM and 8PM UTC on a weekday until November 1, and between 2.30PM and 9PM UTC after it. Outside those hours BloFin may accept only orders that reduce a position (source: BloFin stock futures notice, April 21, 2026).

• Check the current funding rate and its sign on the contract page, remembering that a short receives funding when the rate is positive.

• Look at the calendar: AMD's investor relations calendar shows no scheduled events, so the date of its third-quarter report is still open (source: AMD investor relations calendar).

• Decide what ends the hedge, such as a date or a price, and close it with a reduce-only order when that point comes.

Hedging is not always the better choice. If you would be just as happy selling, a sale ends the funding and margin questions at once. If the worry is about AMD's prospects for years, a hedge kept open that long ties up margin the whole time and rides every swing in funding. A hedge earns its margin and fees over a period you can name.

Frequently asked questions

What is the best hedge for a long AMD stock position?

The best hedge for a long AMD stock position depends on what you want to pay for. A protective put, bought from a broker that lists AMD options, caps the loss below its strike price for an upfront premium. The put can expire worthless if the stock holds up (source: Charles Schwab, hedging in a volatile market). A collar pairs that put with a sold call, which lowers the cost but limits the upside (source: Charles Schwab, hedging in a volatile market). A short perpetual has no premium but needs margin and pays or receives funding.

Can a hedge on the AMD perpetual make money?

A full hedge on the AMD perpetual is built to stand still on price, so it makes money only on the side. That means funding received on the short, plus any small gap between the contract and the shares when you close. A short futures hedge gains as the asset falls, and that gain offsets the loss on what you hold (source: AnalystPrep, hedging strategies using futures). A partial hedge keeps some of the shares' upside, and some of their downside with it.

How long can you keep an AMD hedge open on BloFin?

You can keep an AMD hedge open on BloFin for as long as its margin holds, because the perpetual has no expiry date. A hedge built from dated futures has to be rolled into a new contract before each one expires, a process called stack and roll that carries its own risks (source: AnalystPrep, hedging strategies using futures). The perpetual skips that step, but it keeps settling funding, and BloFin may adjust the contract's parameters without a separate announcement (source: BloFin, AMDUSDT contract information).

How do you close an AMD hedge on the perpetual?

You close an AMD hedge with a buy order for the same amount of AMD, set to reduce-only so it can shrink the short but never open a long. Reduce-only orders are accepted outside regular hours, so the hedge can come off at any time. A reduce-only limit order still fills only if the market reaches your price, so the setting does not guarantee execution (source: BloFin Help Center, Reduce Only). Closing just before a settlement avoids that period's funding (source: BloFin Help Center, funding rates).

Can you hedge only part of an AMD holding?

You can hedge any part of an AMD holding, down to BloFin's minimum order of 0.01 AMD (source: BloFin, AMDUSDT contract information). A half hedge on 10 shares is a 5 AMD short, or 500 contracts, which needs about 1,579 USDT of margin at 2x at the October 5 close, worked out. If AMD then fell 10%, the shares would lose about $632 while the short gained about 316 USDT, so about half of the fall would still reach you. You can add to the short during regular weekday hours as your view changes.

Nothing in this article constitutes financial advice, and nothing in it is a recommendation to buy, sell or hold AMD in any form. A short AMDUSDT Perpetual used as a hedge can be liquidated in a rally while the matching gain sits in a brokerage account, which leaves the shares unhedged and the margin lost. Funding can turn against the short for weeks, and outside regular weekday trading hours, and on weekends and market holidays, BloFin may accept only orders that reduce or close a position, so a lost hedge may not be replaceable until the next session. Past performance does not indicate future results. Do your own research and consider your risk tolerance before you trade on BloFin.
