Rafael Raber had a strategy in the past to sell every time a stock when it was 15% up. He started a dividend growth investing several years ago, but he's now actually asking us for advice. Is it wrong to sell a stock which is up 15% or more to collect additional dividend income on the 15% return? What about his opinion on that one? I've had something similar, but then I've made that mistake before and sold some quality companies and bought other companies like War Green's because the yield was higher. You tend to find out over time that the companies that are gone up 15% will probably go up another 15%.
