Is it unreasonable to double your investment year over year?
One thing I like to do every once in a while is look at the day's market movers. It's a list of symbols that had huge movement. There tend to be a couple of 50+% movers every time I look. In fact today I see ATV moved up 414.48%:  So there it is—doubling your investment in one day and then some is technically possible. The problem is that the market movers chart also has an equal number of symbols that had major movements in the other direction. Today's winner is:  SPCB  lost 40% in one day, and thats the problem. If you invest in anything that can double your investment in one year, it can also halve your investment in one year. Or do better. Or do worse. You really don't know because the volatility is so high.
