If I remember correctly, you aren’t old enough to be close to retirement age, yes?
How much control do you have over the allocation/risk level in your accounts? If you’re really nervous, and you have the ability to re-allocate into lower-risk investments, you could do so.
But…in the long run, any losses you might suffer are likely to be short-ish in duration, unless the economy went into a deep recession/depression for an extended period of time.
I’m 61, and my 401ks and IRA endured the Great Recession of 2008, and the COVID recession of 2020/21. They bounced back strongly after those, which were, of course, years before I was even starting to think about withdrawing any money. I never touched my mix during those, and honestly, I even refrained from looking at the quarterly statements during those years; the losses happened, but, frankly, weren’t relevant.
If you re-allocate into low-risk investments, and the economy doesn’t tank, you lose out on the gains you would have otherwise gotten.
And, for what it’s worth, despite the war in Iraq, inflation, gasoline prices, etc., the S&P 500 is still up 7.9% on price return (8.5% on total return, including dividends) for the year to date, which is a pretty damned good performance, given all the reasons why it shouldn’t be.
