S&P 500 logs first correction in 2 years as Russia-Ukraine conflict escalates. Here’s what history says happens next to U.S. stock-market benchmark

The last time the S&P 500 entered a correction was Feb. 27, 2020, when the market was being whipsawed by fears about the outbreak of the COVID pandemic.

This time around, investors were wrestling with escalating tensions between Moscow and Kyiv, which could devolve into a full-blown war. Wall Street also was wrangling with a surge in inflation and a Federal Reserve that is bent on hiking interest rates to combat growing pricing pressures, which, incidentally, could be exacerbated by Ukraine-Russia tensions.

The decline for the S&P 500 comes about a month after the Nasdaq Composite
COMP,
-1.23%
descended into correction. On Tuesday, the Nasdaq Composite ended down 1.2%, while the Dow Jones Industrial Average
DJIA,
-1.42%
closed off 1.4%.

The good news for market participants is that history suggests that the market tends to eventually bounce back after the broad-market benchmark suffers a correction, gauged by data backdated to 1928.

On average, the index gains 0.7% one week following a correction but declines 0.4%, on average, about two weeks out. Thereafter, the market marches higher in the following three-week, one-month, six-month and full-year periods, according to Dow Jones Market Data.

Of the past 20 corrections that have occurred in the S&P 500, including those that have morphed into a bear market, defined as a 20% decline from a recent peak, the S&P 500 has ended higher 70% of the time.
