The Maginot Line of investing: Why market timing rarely wins

equities “just in time” to avoid a crash, and they will tell you how hard it is to do it twice. Selling is only the first step. The second — getting back in — is often even harder.A few realities investors underestimate:You will likely get the timing wrong.
