The Major Risks of Options
The ways options go wrong, gathered in one place: what buyers risk, what sellers risk, and the risks that come from the instrument itself, with the arithmetic of leverage and of repeated bets.
The short version
An option buyer can lose the whole premium quickly, and has to be right about direction, size, and timing together. Leverage magnifies this: the same money in calls instead of shares can turn a modest rise into a loss. An option seller's gain is capped and the loss isn't, an uncovered call has unlimited risk, and margin calls can force a seller out at the worst moment. Both sides face complexity, wide trading costs on cheap options, and surprises around expiration. Brokerage firms have to approve an account for options before it can trade them, and the approval is a gate, not a judgment that the strategy is sound.
By the end of this lesson, you'll be able to
- Describe the main risks facing an option buyer and an option seller
- Show with numbers how leverage changes the result of the same view on a share
- Explain why being right about a share doesn't guarantee a profit on its options
Why this matters
Every lesson in this module has touched on a risk in passing. This one puts them side by side, because options rarely hurt people through one dramatic failure. They hurt through several ordinary features working at once: a deadline, leverage, a cost for waiting, and obligations that arrive on someone else's schedule. The official catalogue is the disclosure document that brokerage firms are required to give options customers, Characteristics and Risks of Standardized Options.1 Much of what follows is that document's list, with numbers attached.
Risks for buyers
Losing all of it, quickly
An option holder runs the risk of losing the entire amount paid for the option in a relatively short period of time. An option is a wasting asset, worthless once it expires, and a holder who neither sells nor exercises before then loses the whole investment.2 With shares, a total loss requires the company to fail. With options, it requires only that the share price be on the wrong side of the strike on one date.
Needing to be right three ways
A buyer has to be right about the direction of the move and also about when it happens. If the price doesn't move far enough to cover the option's cost before expiration, the buyer may lose all or much of the investment. A shareholder with the same view can simply wait.2 Add the size of the move, and an option buyer needs three things to go right where a shareholder needs one.
| What happens | Shareholder | Call buyer |
|---|---|---|
| STU rises to $54 in three months | +8% | −100%: right direction, not far enough |
| STU rises to $57 in three months | +14% | 0%: breaks even |
| STU is flat for three months, then rises to $65 | +30% | −100%: right direction and size, too late |
| STU rises to $65 within three months | +30% | +400% |
Leverage
Options offer leverage, the ability to magnify the purchasing power of the premium, and leverage can come with the risk of significant losses.1 How much risk depends on how the leverage is used.
Three investors each have $5,000 and expect STU, at $50, to rise over three months. One buys 100 shares. One buys a single $50 call for $390 and keeps $4,610 in cash earning 4% a year. One buys twelve $50 calls for $4,680.
| STU at expiration | 100 shares | One call, rest in cash | Twelve calls |
|---|---|---|---|
| $40 | −$1,000 (−20%) | −$344 (−7%) | −$4,680 (−94%) |
| $50 | $0 | −$344 (−7%) | −$4,680 (−94%) |
| $54 | +$400 (+8%) | +$56 (+1%) | +$120 (+2%) |
| $58 | +$800 (+16%) | +$456 (+9%) | +$4,920 (+98%) |
| $62 | +$1,200 (+24%) | +$856 (+17%) | +$9,720 (+194%) |
The single call with cash is the cautious use: the loss is limited to about 7% whatever happens. Twelve calls is the leveraged use. It nearly triples the money at $62 and loses 94% of it if STU merely stands still.
The middle row deserves a second look. STU rose 8%, the investors were right, and the fully leveraged one made 2%. The share had to rise almost 8% before twelve calls broke even at all. Leverage didn't just raise the stakes. It moved the goalposts.
Paying for time and for fear
Two costs run quietly against every buyer. Time value decays daily and fastest at the end, as Intrinsic Value, Extrinsic Value, and Moneyness showed. And a premium bought when implied volatility is high can shrink even when the share cooperates, as Implied Volatility showed with a call that lost a third of its value on good news.
