Is market capitulation a buying opportunity?
In theory, capitulation should be a buying opportunity. However, consistently and accurately determining when capitulation is occurring would require a crystal ball. Only in retrospect, after a sustained recovery has begun, can you know the stock market or an asset has reached capitulation. Until then, it's impossible to know whether prices could drop even further.
Since market timing doesn't work, a better approach is dollar-cost averaging, which is when you invest on a regular schedule. For example, if you automatically invest $500 a month in your individual retirement account (IRA) or 401(k), you're practicing dollar-cost averaging. You won't always get the lowest prices on your investments, but at least you'll lock in some lower prices when the market is down.
