California economy: Tech stock dips historically correlate with slower hiring and lower incomes

The recent decline in technology shares has raised questions about the potential impact on California's workforce and household finances. While daily stock movements often dominate headlines, a half-century of economic data suggests that sustained drops in tech stocks can signal shifts in the state's labor market and personal income levels.

Since 1976, the Nasdaq Composite Index has entered a crash mode 21 percent of the time, defined as a drop of 10 percent or more over the course of a year. The most severe decline occurred in the year ending in the third quarter of 2001, when the index lost 52 percent of its value. Currently, the index remains up 8 percent for the year ending in October 2026, though this gain is down from nearly 50 percent in April.

Employment in California often cools following these tech market reversals. In the year after the Nasdaq fell by 10 percent or more, the number of employed Californians decreased 43 percent of the time. The median annual growth rate for employment during these post-crash periods was just 0.2 percent. This stands in sharp contrast to the 1.6 percent annual increase that has been the norm for the state since 1976.

The worst employment drop in this historical pattern occurred during the Great Recession. In the year ending in the third quarter of 2009, the number of employed Californians declined by 5 percent. This period marked the low point for job retention following a tech stock slump.

Personal income trends also show a correlation with tech market performance. Total personal income, which tracks wages, other earnings, jobs, and population, fell 18 percent of the time in the year following a Nasdaq crash. The median growth rate for personal income in these years was 2.3 percent, lower than the typical 2.8 percent increase observed over the past five decades.

The steepest decline in personal income also occurred during the Great Recession, with a 3 percent drop in the year ending in the fourth quarter of 2009. Historical context shows that these tech crashes have coincided with broader economic stressors, including the high inflation of the 1980s, the brief recession of the early 1990s, and the dot-com bubble burst of 2000.

Despite the volatility, the Nasdaq has delivered a median annual profit of 15 percent to investors over the last half-century. This wealth creation has made the tech industry a central pillar of California's economy, particularly in the Bay Area. The current slowdown in tech stocks thus warrants attention from those monitoring the state's overall business climate.
