Uptick Rule Law and Legal Definition
Uptick Rule is a federal law requiring that short sales be executed on an uptick or a zero plus tick.
The rule was defined by U.S. Securities and Exchange Commission (SEC) which summarized it: "Rule 10a-1(a)(1) provided that, subject to certain exceptions, a listed security may be sold short (A) at a price above the price at which the immediately preceding sale was effected (plus tick), or (B) at the last sale price if it is higher than the last different price (zero-plus tick). Short sales were not permitted on minus ticks or zero-minus ticks, subject to narrow exceptions."
The rule went into effect in 1938 and was removed in 2007. In 2009, the reintroduction of the uptick rule was widely debated, and proposals for a form of its reintroduction by the SEC went into a public comment period on 2009-04-08.
