Researcher, I think that strategy makes some good sense:
"I think it's a mistake to completely exclude buying an undervalued stock just because it's already had a big run .... I can understand not wanting a full sized position, but at a minimum I take a small position with the intent of adding on a pullback, if there is one. Valuation takes precedence over RSI."
I have seen lots of $1 stocks with strong earnings and solid balance sheets triple, quadruple and more, but I have yet to see one go below zero.
