Due diligence is a must. I don't blindly follow anyone, especially "experts". I buy and sell based on my instincts, reading, chart and volume study, risk tolerance, after analyzing trends. Mistakes have been great teachers.
Individual day traders around the globe long and short. During .com period I bought everything at high I lost lot. Last 5 year I recovered all my loss. I am trading only value stocks no more high flyer. Only swing trade if I want.
