The 1962 U.S. stock-market drop known by a nickname tied to a military confrontation was the Kennedy Slide.
The Kennedy Slide took place during the sharp market decline of May and June 1962, when the Standard and Poor’s 500 fell about 22.5% from its December 1961 high to its June low. The episode was named after President John F. Kennedy, although it was not caused by one presidential decision alone.
Economic concerns included slowing growth, reduced corporate profits, and uncertainty about business conditions. The market’s decline also reflected the broader postwar pattern in which investors reassessed high share valuations.
The military reference in the question points to the Cold War context surrounding Kennedy’s presidency, not to a formal market mechanism. The Kennedy Slide is distinct from the Cuban Missile Crisis, which occurred later in October 1962, and from the 1987 Black Monday crash.
