Jim Cramer's 20% Rule for Picking Winning Stocks Explained

CNBC's Jim Cramer has long been one of Wall Street's most recognizable voices, and his latest guidance centers on a straightforward numerical threshold he applies when evaluating whether a stock is worth buying.

While the original source did not provide granular detail on every mechanic of the rule, the core premise reflects a broader discipline Cramer has championed for years: only commit capital to a stock when you can reasonably project a gain of at least 20% from your entry point.
