I will hold on to MRK for a while and see. For my next purchase, should I then at companies reaching a new low, do research to see if they have new products coming out (etc to turn things around ) and then use MACD to time my purchase? If I had bought MRK at 95, I would have made a $8 profit also. Now I am stuck with holding on to it. Also how does this board work. Do you get pay for running it? Your advice is better than any books I have read.
