You haven’t lost any money.

The value of your investments has decreased. If this is in a retirement account that you don’t plan to touch for the next 30 years or so, it is practically inconsequential what has happened in the market YTD. This is like having tickets for an amazing vacation but staying home because your car needs an oil change.

If anything you should be considering investing as much as possible because the equities you will purchase are on sale compared to a year ago. Not to mention that your cash is losing value due to inflation.

Invest consistently and often, and don’t worry about momentary ripples in a multi-decade journey.
