What it means
A futures contract on an index is ordinary, while a futures contract on one company's shares is the distilled version. Single stock futures let a trader commit to a stock's future price with a fraction of the cash.
The leverage is the attraction and the hazard: margin of around 20% controls the full position, so small price moves become large account swings. The CFTC's overview of security futures explains the unusual parentage: these products are jointly regulated by the CFTC and the SEC, because they are both futures and securities at once.
That dual citizenship came late, since the United States banned single stock futures for nearly two decades and legalised them only in 2000, with the joint regulatory framework as the price of admission. The American experiment ended quietly, as the dedicated exchange, OneChicago, closed in 2020, leaving the product thriving mainly on overseas venues.
The economics remain logical: shorting via futures avoids the borrow cost of shorting stock, and hedging a concentrated position avoids selling it. The risks concentrate like the stock, because no diversification softens a single name, gaps hit leveraged positions hard, and thin liquidity can make exits expensive.
For a non-finance reader, a single stock future is a down payment on a stock bet: one-fifth of the money controls the whole wager, and the settlement date collects the difference. Corporate actions complicate the contract, since dividends, splits and mergers require adjustments, and the futures price quietly embeds expected dividends until the ex-date.
Arbitrage keeps the price honest, because the futures quote tracks the stock plus financing minus dividends, and any gap is closed by traders who buy one leg and short the other. Market makers face the inventory problem in miniature, since hedging a one-name futures book requires the underlying stock, so borrow costs and short-sale constraints leak into the quotes.
Institutions use them for transitions, because shifting a large single-name exposure between managers can run through futures, moving the risk before the cash trades settle. The product's history is a regulatory parable: an eighteen-year ban, a negotiated peace between two regulators, a dedicated exchange, and a quiet funeral two decades later.
In practice
Real-world examples.
Example
A manager shorts single stock futures against a taxable winner through earnings, deferring the sale. The hedge protects the value of the holding for the quarter while the unrealised gain stays untouched.
Example
A 12% slide in the stock is offset by the futures gain, minus financing and roll costs of about 1% a quarter. The manager checks the net result against the cost of the alternative, which was selling the shares and triggering the tax.
Example
The OneChicago closure in 2020 ends the US experiment while overseas venues keep the product alive. A trader who relied on the US contracts must move to a foreign exchange, with different trading hours, margin rules and access arrangements.
Formula
Calculation
Contract value = share price x contract multiplier (often 100 shares). Initial margin is roughly 20% of contract value. Daily mark-to-market settles gains and losses in cash until expiry or offset.
Worked example. A fictional stock trades at $50 and the contract covers 100 shares, so contract value = $50 x 100 = $5,000. Initial margin at 20% = $5,000 x 20% = $1,000. If the stock rises 10% to $55, the contract value becomes $5,500 and the long holder gains $500, which is $500 / $1,000 = 50% on the margin posted. If the stock instead falls 10% to $45, the long holder loses $500, or 50% of the margin, and the short holder gains the same amount.Case study
Seen in the real world.
This case study is fictional and illustrative. A made-up portfolio manager in Singapore holds a large, taxable gain in a bank's shares and wants protection through earnings without selling. Single stock futures offer a clean answer: short contracts covering the position for the quarter. The hedge performs its arithmetic when earnings disappoint, the stock slides 12%, and the futures gain offsets the holding's loss almost exactly, minus financing embedded in the futures price. The treasurer's review praises the tax deferral and then audits the cost.
The margin posted earned nothing, the roll into the next quarter charged a spread, and the net protection cost roughly 1% for the quarter. A colleague argues the same hedge with put options would cap the cost upfront, and the manager concedes the point for tail risk while defending futures for tight, short windows. The final policy line is the product's honest summary: single stock futures are surgical tools for concentrated risk, cheapest for short horizons, and unforgiving when treated as a casual substitute for owning or shorting shares outright. The position is unwound after results, the tax bill deferred, and the lesson filed.
Watch out
Common mistakes.
- Underestimating leverage; 20% margin turns a 10% stock move into a 50% account swing, in both directions.
- Assuming index-like behaviour; a single name carries company-specific gap risk that no diversification dilutes.
- Ignoring liquidity; thin contracts widen spreads, and the exit can cost more than the theory saved.
Questions
People also ask.
What are single stock futures?
Futures contracts on one company's shares, committing buyer and seller to a set price at expiry, with margin around a fifth of contract value.
Who regulates them?
In the US, jointly the CFTC and SEC under the security futures framework created when the products were legalised in 2000.
Are they still traded?
The US venue OneChicago closed in 2020; single stock futures remain active mainly on exchanges outside the United States.
