A graph is like a magic mirror .It always talks about the future and it is upto the analysts ow best he can understand the language of the mirror. Chart always gives early signals of weak or strong fundamentals taking place in a company or a sector in the future .It's upto an individual how best he can analyse and catch the trend without being biased towards a company or a sector.Hundreds of companies have vanished in last decade leaving a investor high and dry with dead stocks in a portfolio.The stock market always moves in a cycle --a bull phase and a bear phase .It always punishes the greedy and the fear never allows one to buy at the right time .
