I have started investing in stock market about 18years ago and follow it very closely. I always invest for long term... 5 years plus and hence has no interest in short term market fluctuations. I have investments in diversified mutual funds too. I believe in concentrated portfolio of stocks of 4-5 companies and let my investment in mutual fund do the divesification. I have 60% investment in direct stocks ( four stocks) and 40% in diversified mutual funds (Five funds)
