I have a few thousand in a Vanguard LifeStrategy fund, which I invested two years ago before the stock market nose dived. They are finally almost back up to pre-2022 levels and I'd really like to withdraw the money, but I'm aware that there's a lag of a few days between making the withdrawal request and actually getting the funds, in which time they could go down again. Is there anything I can do to mitigate this that i haven't thought of, or do I just need to take the plunge and hope for the best?!
