I buy many tickers in small lots. This allows me to buy/ sell stocks at-will. And, I sell winners and losers with equal certainty and resolve. I would rather miss getting the highest price than lose potential gains from hoping an up trend continues.
I've had money and lost it all and had it again. I've survived investing in the last 4 market crashes back to 1987. Made a lot of mistakes and learned what was needed to have money stick now. I play both sides long and short. Prefer swing trading.
