S&P 500 daily close, price only. Yahoo Finance, ^GSPC, to 30 Oct 2026.
What happened
With the Vietnam War and the Great Society spending at once, inflation began to climb. The Fed tightened in 1966, credit dried up and the index fell about 22%. It recovered through 1967 and 1968, a year of political turmoil at home.
Play it
The Trading Simulator replays two years of the S&P 500 from January 1966, day by day: stay invested or move to cash, and finish ahead of the index if you can. The game counts dividends, so its figures differ from the price figures here.

How the figures are measured
From the S&P 500's daily closes, price only: dividends are not included. An episode's fall is the largest drop from a close to a later close within its months, from the highest close before the low. Where an episode's text measures from a peak in the episode before or to a low in the episode after, the figures do too: the Great Depression from the 1929 peak, Sputnik and the 1957 recession from the 1956 high, and the Volcker squeeze to the low of August 1982. Months are calendar months, rounded. Back at the peak is the first close at or above the peak's close.
