Could go for value based things, if P/E of S&P 500 is below 10 buy $1000 of ${ETF}

If you can come up with a systematic strategy in a one-liner, that gives you consistent, good risk-adjusted returns, let me know as I quite fancy being a billionaire.

Saying that, "Buy Low, Sell High" isn't a bad strategy ;)

Yeah, can't quite shake the feeling that if it was really that good, you'd just use it vs. (eventually) sell it.

[maerF0x0]

agreed. The hard part is not buying bad companies that have low P/E because their chances are slim to none.
