  • Assessing the Safety of S&P 500 ETFs Amid Market Turbulence
    July 23, 2026, 4:05 PM EDT.

Despite this, these ETFs are susceptible to steep declines in the event of market crashes and cannot be considered free of risk. Those with a longer timeline until retirement may benefit from remaining invested through periods of volatility, in contrast to individuals approaching retirement who could encounter heightened exposure. Maintaining a long-term perspective remains critical to capturing potential recovery and gains.
