I agree that NASDAQ & Large Cap stocks are less manipulated, hence safer, but in my case, I didn't put away much money for retirement over the yrs., and now I'm in my early 50's and don't have the time to invest in stocks that return maybe 30%/yr. I need the high returns that only the small-cap stocks can deliver.
High Risk = High Gain!
IF, you can trade the Penny Stock Market successfully, the gains can be astronomical, compared to the Large Caps!
