Nifty Fifty Bubble 1968–1974

The Nifty Fifty was not a formal stock index. It was an informal label for roughly fifty U.S. large-cap growth stocks that institutional investors increasingly treated as “one-decision” holdings: companies so dominant and dependable that they could supposedly be bought and held regardless of valuation. The broader U.S. market peaked around December 1972 to early January 1973, then rolled into the 1973–74 bear market as inflation accelerated, the Bretton Woods system collapsed, the oil shock hit, and recession began. The S&P 500 fell roughly 48% to 50% from peak to trough, while many Nifty Fifty names lost 60% to 90%.
