Nancy Tengler, CEO and Chief Investment Officer of Laffer tengler Investments, has advised investors to stay invested during world conflicts, noting that history shows that volatility at the start of conflicts tends to settle quickly and improve the stock market. She cited Russia's invasion of Ukraine as an example of this, stating that stock prices initially fell before recovering quickly. For those with 401(k)s, IRAs, or individual investment accounts, Tenglers recommends staying long stocks and investing if possible. She also suggests that most retirement savings should remain in the market.
