What was the name of the 1973–1974 U.S. bear market linked to the oil crisis and the collapse of the Nifty Fifty?

The 1973–1974 stock-market crash was the U.S. bear market linked to the oil crisis and the collapse of the Nifty Fifty.

From January 11, 1973, to October 3, 1974, the Dow Jones Industrial Average fell about 45%. The decline occurred during high inflation, slowing economic growth, the 1973 oil crisis, and political uncertainty connected with the Watergate scandal. The market had also assigned very high valuations to a group of large companies known as the Nifty Fifty.

When interest rates and inflation rose, investors became less willing to pay exceptional prices for dependable growth. Many of those companies fell sharply, showing that even famous, profitable businesses can be overpriced.

The episode is sometimes called the 1973–1974 bear market rather than a single-day crash. It differs from the 1970 decline and from the 1979–1980 energy-related weakness because its main fall extended across nearly two years.
