I trade short term useing technical annalysis to pick trending stocks. It is documented that 70% on capital per annum can easily be made useing this method.
The resources sector in Australia is on a bull run at the moment and I have made 20% in only one month and that includes taking small losses when a given stock doesnt perform when expected. Trading requires disipline to sell when stocks are not performing and take a small loss rather than let the loss become larger every day. Remember that stocks fall 3times faster than they rise.
