I invested in MU a couple months ago, and I'm now down by 20%. I could keep dollar cost averaging, or I can cut my losses now, sell my shares and reinvest them in SPY. This is really the only "risky" stock in my portfolio right now, since my other holdings are mostly index funds and relatively safe stocks like Costco, Coke and Google. I'm usually quite risk averse, but just this once I thought I'd take a chance by buying into the memory stock hype and then immediately regretted it lol. What should I do?
