Non-Equity Option

A non-equity option is an options contract whose underlying asset is anything other than shares of an individual company's stock. Instead of giving you the right to buy or sell 100 shares of a specific company, it gives you the right to buy or sell (or, in the case of index options, receive a cash payment tied to) something else entirely: a stock index, a commodity, a currency, an interest rate product, or a futures contract.

The most common examples a beginner encounters are index options, like those on the S&P 500 or Nasdaq-100, and options on futures, such as crude oil or gold futures. These trade and settle differently from a plain stock option. Many index options are cash-settled, meaning that at expiration no shares or barrels of anything change hands; instead the difference between the strike price and the settlement value is paid in cash. Options on futures, by contrast, typically settle into a futures position rather than cash or shares.

The nuance that trips people up is that "non-equity" doesn't mean "exotic" or "risky" as a rule; it just means the underlying isn't a single company's stock. But the mechanics can differ in ways that matter a lot: settlement style (cash vs. physical vs. futures), exercise style (some settle only at expiration, called European-style, versus anytime before, called American-style), and how margin and position limits are calculated. These differences affect tax treatment and risk in ways that trip up traders who assume every option behaves like a stock option.

Regulators and brokers also draw this line for margin and reporting purposes, since non-equity options can carry different margin rules and, in the US, different tax treatment under certain tax code provisions than equity options.
