The initiation
S&P 500 55.50 · −3.97 · −6.68%
A generation that thought the floor was concrete finding out it was weather. Worst day since the Depression — recovered, insultingly, within days.
The day's protagonist
A new generation's paper losses — no symbol.
Move: −6.68% — the postwar cohort's first real decline
The market had been sliding since December — the "Kennedy Slide" — and April's confrontation between the President and U.S. Steel had soured Wall Street on the administration. On this Monday the sellers simply arrived all at once, with no single trigger anyone could name then or since. The S&P fell 6.68%, its worst day since the Depression's aftermath; the Dow's 34.95 points was the second-largest drop on record; the ticker ran late, 1929's ghost walking the floor. Millions of postwar investors had never seen a real decline. This was the initiation — followed, almost insultingly, by a V-bottom the next morning and new highs within the year.
The deeper account
April 1962: Kennedy forced U.S. Steel to roll back a price increase — the market read it as an administration hostile to business, and the slide steepened.
The SEC's Special Study of Securities Markets, commissioned after the break, became a founding document of modern market structure.
In the photograph of this day the slide is doing what slides do and the children know it: the line at the ladder never stops. Only the man in the grey suit watches the descent as if it were news. It was his initiation too — the first time the postwar crowd learned what he has known since 1929.
AT&T, IBM, and the era's blue chips bore the worst of the selling; the ticker fell far behind and closed the day, as in 1929, printing prices from a market that no longer existed.
Five months later the Cuban Missile Crisis marked the bear's true bottom — the market began rising while the missiles were still in Cuba.
The artifact
The card records the day exactly: the steepest single-day fall between 1929's aftermath and 1987, no trigger anyone could name then or since, and a recovery that arrived the very next morning. The open cause line is the historical verdict — the SEC's Special Study of Securities Markets, commissioned after the break, became a founding document of modern market structure without ever really answering the question. The keeper's note is the part the postwar generation needed: the line at the ladder never stopped.
