I can't get wiped because:
1. I only have 1/4th of my investment capital in any one specific stock at any given time.
2. The average time length my money is in a stock is only a few hours.
3. The game I play doesn't allow for stocks to drop to zero in a matter of a couple of hours. My picks are too strong financially.
You pay a commission every time you trade and your portfolio is pretty small now. Assuming you have doubled your money to $6,000, your biggest trade is only $1,500.
You get wiped out by taking a string of losses that is longer than you now think possible, but is more likely than your 3k-to-a-million-in-2-years scenario.
You get wiped out when after-hours opens 20% down on too many trades in a short time period.
You get wiped out by holding Lehman Brothers at the wrong moment.
You get wiped out when China shuts down the internet at the wrong moment.
Think about it, by holding so many stocks, you are increasing your risk of holding on to someone that will announce a bankruptcy at market close and there goes almost a quarter of your portfolio by the time you can react.
And by wiped out, I didn't mean my entire portfolio, I meant my profits and a bit more.
You are playing a momentum game and using long-term tools. The stocks you mentioned are very volatile and you have lucked into the upward volatility and this upwardness has been biased by an overall upward trend in the market while you have been trading. Nothing you are doing hasn't been tried before.
