What Is the Uptick Rule and Is It Still in Effect?

The uptick rule was a significant regulatory measure in financial markets, primarily affecting short selling. It represented an early effort by regulators to manage market dynamics and prevent certain trading practices from negatively influencing security prices. This rule aimed to foster more orderly market conditions.

Defining the Uptick Rule

The original uptick rule, Rule 10a-1, was implemented by the U.S. Securities and Exchange Commission (SEC) in 1938. This regulation stipulated that a short sale of an exchange-listed security could only occur if the last trade price was higher than the previous trade price, known as a “plus tick” or “uptick.”

An additional provision, the “zero-plus tick,” allowed a short sale if the last trade was at the same price as the immediately preceding trade, but that price was higher than the last different price. For example, if a stock traded at $10.00, then $10.01, and then $10.01 again, the final $10.01 trade would be a zero-plus tick, permitting a short sale. This mechanism was designed to ensure short sales did not initiate or accelerate downward price movements.

The Rule’s Objective

The original uptick rule aimed to prevent short selling from exacerbating market downturns. Regulators sought to curb the potential for short sellers to drive down stock prices during market stress or instability. The rule also aimed to maintain orderly market conditions and discourage manipulative trading practices that could contribute to rapid price declines.

By requiring short sales on an uptick or zero-plus tick, the rule created a “speed bump” for short sellers. This ensured short sales were initiated in rising or stable market environments, rather than contributing to a downward spiral. The objective was to instill investor confidence by mitigating concerns that short selling could unfairly depress security values.

Current Market Regulations

The original Uptick Rule (Rule 10a-1) was repealed by the SEC in 2007, following years of testing and deliberation. This decision was partly due to advancements in electronic trading and market structures. The financial crisis that emerged shortly after its repeal prompted a reevaluation of short selling regulations.

In response, the SEC adopted Rule 201 in 2010, known as the “Alternative Uptick Rule” or “Circuit Breaker Rule.” This rule functions differently from its predecessor, designed to be more targeted in its application. Rule 201 is triggered for a security when its price declines by 10% or more from its previous day’s closing price.

Once triggered, the short selling restriction under Rule 201 applies for the remainder of that trading day and the entire following trading day. During this restricted period, short sales are only permitted if the price is above the current national best bid. Rule 201 applies to all equity securities listed on a national securities exchange, whether traded on an exchange or in the over-the-counter market.

Rule 201 aims to prevent abusive short selling from further driving down a stock’s price after a significant intra-day decline. It also aims to preserve investor confidence and facilitate the ability of long sellers to sell their shares before short sellers during periods of significant downward price pressure. This modern approach focuses on restricting short selling only when a stock is under substantial stress.
