Over the years I changed jobs a few times (for salary optimization reasons) but kept the 401k balances in my old employers’ 401k sponsor accounts. I currently have three 401k accounts. I know from past experience that it takes over a month to transfer a 401k balance from one account to another, because the old 401k sponsor has to physically mail you a check, then you have to mail that check to your current 401k sponsor. It takes over a month to do that. You can significantly lose a lot of gains especially when the market is trending up. Therefore, I’m wondering if it’s a good strategy to instead keep the balances where they currently are and wait for the next recession/market downturn to transfer balances? Is this a good strategy?
