Of the three funds you mentioned, I'd be buying Windsor right now. If you need more safety, redirect future investments to cash instead. Going to PRPFX now is chasing performance. In fact, it does not do well during bull markets. See if PRPFX compels you to invest when the S&P is doing well. Same with STAR.

You gotta buy low and you gotta sell at a profit. For a safety cushion, you need to accumulate cash.
