Futures, perpetuals, and leverage: useful tools, poor defaults

What are futures and perpetuals?

Futures and perpetuals are derivatives: contracts whose value depends on an underlying asset or reference price. They can serve a specific risk-management purpose for sophisticated investors and businesses. For an everyday investor building wealth over years, we generally favor a simpler starting point: fully paid investments without leverage, with broad diversification rather than concentrated speculation.

A conventional futures contract has an expiration and defined settlement terms. Depending on the contract, settlement can involve delivery or a cash payment. A classic perpetual has no scheduled expiry and commonly uses funding payments to help keep its price near the underlying market. Some products marketed as perpetual-style have a maturity; always read the actual specification.

Buying a price-tracking contract does not necessarily give you the underlying asset. A stock-index future is not ownership of all the businesses in the index. That distinction affects what you hold, how cash moves, and what can force the position to close.

Where these tools make sense

CME Group’s hedging examples include producers managing the risk of falling sale prices and buyers managing rising input costs. A business with an existing exposure can use an opposing futures position to reduce uncertainty. The derivative’s profit or loss should be evaluated alongside that business exposure, not as a stand-alone contest.

A sophisticated portfolio manager might temporarily adjust market exposure without selling every holding. A market maker might offset inventory risk. A trader running a carefully managed relative-value strategy might use both an asset and a derivative. These are specific jobs requiring position sizing, reliable operations, collateral planning, and an understanding of how the two prices can diverge.

Hedging does not erase risk. A contract may track a different price from the one that matters to the business, and gains in one place may not arrive in time to meet a margin call elsewhere. Expertise means planning for those mismatches; it does not mean that adding a derivative automatically improves every portfolio.

Leverage makes the exposure larger than the cash posted

Leverage compares your market exposure with the capital supporting it. US$1,000 supporting a US$10,000 position is 10 times exposure. A small move in the underlying price can therefore cause a large change relative to your US$1,000. The multiplier applies to losses as well as gains.

Initial and maintenance margin are collateral requirements, not a discount on ownership. Initial margin is required to enter; maintenance margin is the amount needed to keep the position open. Requirements can change. Futures margin is different from an ordinary loan used to buy a share, even though both arrangements can create leverage.

If losses leave too little collateral, a provider may close positions or require more money. The CFTC warns that leveraged futures losses can exceed the initial amount invested. Contract terms, market gaps, and the venue’s protections matter, so the amount shown as your opening margin should not automatically be treated as a guaranteed maximum loss.

A 5% fall can cost half your capital

Suppose you post US$1,000 for a linear long position with US$10,000 of exposure. If the underlying price falls 5%, the position loses about US$500 before costs: half the starting capital. A fully paid US$1,000 holding experiencing the same price move would lose US$50. The difference comes from exposure, not from a more accurate forecast.

A 10% fall would theoretically consume the entire US$1,000 margin before costs. In practice, maintenance requirements can trigger liquidation earlier. The provider may use a mark price and its own rules rather than the last price on the chart. This example is simplified arithmetic, not a liquidation quote for a specific platform.

Now imagine the market falls and later recovers. Someone holding a fully paid asset may still have the position, assuming they did not sell. A liquidated trader cannot benefit from the rebound in a position that has already been closed. Being eventually right about direction does not help if the path exhausted your collateral first.

Funding, fees, and liquidation keep the clock running

Funding payments commonly pass between long and short perpetual traders. Depending on the rate, you may pay or receive them. They are distinct from a platform’s trading fee and can change over time. A positive funding receipt today is not a fixed yield you can assume will continue.

For illustration, a 0.01% funding payment on US$10,000 of notional exposure is US$1 for that interval. That is 0.1% of US$1,000 in collateral. Several intervals, changing rates, entry and exit fees, and spreads can materially alter the outcome. The relevant base is often the large exposure, not the small deposit that made it accessible.

Coinbase’s international derivatives guidance explains that insufficient collateral can trigger automatic liquidation and less favorable execution. This is an example of venue rules, not a universal formula. Cross-margin arrangements can put other shared collateral at risk, while isolated-margin rules have their own limits. A stop order also cannot promise a particular execution price through a market gap.

Why unleveraged investing is a better default

For many people with a long horizon, broad equity exposure offers a clearer connection to productive businesses than repeatedly managing leveraged price bets. A fully paid, unleveraged holding avoids the margin-driven liquidation mechanism described above. It still has market risk, and a single company can fail. Removing leverage does not make a poor asset safe.

Index funds follow a specified index and may offer a straightforward way to hold a basket of securities. Read the holdings, fees, and mandate: a broad market fund differs from a narrow sector fund or a leveraged ETF. The words “index” and “ETF” alone do not establish diversification or low risk.

Concentration risk matters even without borrowing. Several technology stocks can still leave you exposed to similar forces. For a Mexican, Brazilian, or Argentine investor, a dollar-denominated investment also moves in local-currency terms when exchange rates change. Match investments to the purpose and timing of the money; funds needed soon should not depend on a stock-market recovery.

This is a case for a manageable process, not a promise that equities always outperform derivatives over every period. Regular contributions, suitable diversification, and controlled costs let the plan rely less on constant monitoring and precise short-term timing.

Keep the same discipline when investing through Lex

Lex’s supported stock tokens let eligible users obtain exposure through their self-custodial wallet. Review the asset and quantity you are buying, the quote, and the issuer’s conditions. Tokenized stocks add issuer, custody-arrangement, liquidity, and smart-contract risks to the underlying market exposure. They are not interchangeable with ordinary shares in every respect.

A small collection of those tokens is not automatically a diversified index portfolio. This guide discusses index funds as a general investment option; it does not imply their availability in Lex. Your financial plan may sensibly use more than one account or provider to obtain the mix of assets you need.

The decision to use a derivative should begin with a specific exposure to manage and the resources to manage it. If the goal is simply to invest for the future, adding leverage often creates work and failure points that the goal does not require. Simplicity can be a deliberate investment choice.
