The Securities and Exchange Commission (SEC) implemented Regulation SHO, more widely known as the SSR, or short-sale restriction, Rule in 2005 to prevent abusive short-selling tactics and protect market integrity. Primarily aimed at “naked” short selling, it forced short sellers to first borrow the stock they were going to short, eliminating failures to deliver (FTDs) associated with this type of transaction.

Options, derivative contracts that give traders the right but not obligation to buy (in the case of calls) or sell (in the case of puts) an underlying asset at a specified price, are not exempt from the SSR rule. This means that shorting and initiating a short position in options falls under the same restrictions as shorting stocks.
Understanding the SSR Rule
In a short sale, the seller does not actually own the security being sold but borrows it from a brokerage account, planning to buy the stock at a later date at a lower price and then return the borrowed shares, thereby pocketing the profit. In naked short selling, the investor does not borrow the shares first, opening the door to FTDs, a bullish factor that can artificially inflate price.
The SSR rule aims to limit naked shorting by making sure short sellers have borrowed shares before initiating a sale. Specifically, the rule is in effect when a stock’s price has declined by 10% from the previous closing price. SSR remains in place from that point onwards until the end of the trading day if, in addition, there are more shares sold short than purchased (known as a “short sale price test”).
SSR and Options
The SSR Rule applies to all equity securities, including options, in the following scenarios:
- When creating (or selling) a naked put option
- When covering a previously sold naked put option
- When creating a short call option
Importantly, the SSR does not apply to buying (initiating a long position) options, exercising options, selling options against underlying stock positions, or closing covered short positions.
Impact on Options Traders
The SSR rule can significantly impact the trading strategies of options traders. For instance, during periods of market volatility or when a stock’s price is declining, initiating new naked put positions could be prohibited if the SSR rule is activated. Similarly, traders looking to create short call options to capitalize on downside risk may face limitations.
Traders should monitor and be aware of the SSR status of underlying stocks when engaging in options trading, as the rule’s implementation can introduce unexpected obstacles or alter potential strategies.

- Constantly monitor price action, staying informed of the underlying equity’s performance and potential volatility.
- Consider making smaller trades or spreading out trades to avoid market impact and potential trading halts.
- Explore alternative trading strategies to navigate the restrictions and seek potential opportunities.
