Buying the dividend stocks in between the high and the low is always a good idea, never sell for less than what you paid for it unless it makes sense in your long term strategy. When your stocks have dropped below what you paid for them, there are sometimes a strong urge to sell to keep from losing any more money. This may not be a good plan in the long run. Dividend investing is a long term investment strategy. The 10minute trading strategy is a twist on this plan. Buying to collect the dividend and moving onto the next profitable company will allow you to increase your bottom line. Price movements may put your trading activities on hold for a bit but it is all just part of the game. Remember the end game or the worse case scenario "collecting dividneds". Collecting the dividends and just holding onto the stock until it recovers. If the stock never recovers in price then you have a choice to collect more dividends through out the years or take the loss and move on to other dividend stocks and keep the rotation moving.
Remember you never lose with a dividend stock until the company goes bankrupt (choose wisely) or you sell at a loss, something we urge you not to do.
