The Vanguard S&P 500 ETF (VOO) experienced a 9% decline over two months due to the impact of the Iran conflict on the U.S. economy, including higher inflation and oil prices. However, the ETF has since recovered all of those losses in less than a month, highlighting the resilience of the broad stock market and the value of a long-term, buy-and-hold investing approach.

Why it matters

This period of market volatility provides an excellent case study on the benefits of long-term investing. Investors who sold during the downturn likely missed out on the swift rebound, while those who maintained a long-term focus were able to capture the gains. This demonstrates that trying to time the market during geopolitical events is often futile, as the market tends to recover quickly from such shocks.

The details

The Vanguard S&P 500 ETF fell 9% over two months, from its all-time high in early February to its lowest point in April. This decline was in line with historical patterns, which show that geopolitical events typically lead to market declines of 5-15%. However, the ETF has since regained all of those losses in less than a month, reflecting the market's ability to bounce back quickly from such shocks.

  • In February, the annualized inflation rate in the U.S. was 2.4%.
  • In April, the inflation rate is forecasted to jump to 3.6%.
  • Brent crude oil prices were around $72 per barrel at the end of February, but have since risen to around $100 per barrel.
