Wardsown, there are three things you can do. (1) Let your dividends compound by automatically buying new shares each month. At a yield of 12% you will double your money in a little less than six years. (2) Average down. When the price per share goes down, buy more shares to bring your average cost per share down. Or, (3) accept that some of the money you invested a year and a half ago has gone to money heaven, sell out and take a tax loss and move on to another stock.
I've owned various funds from a number of different companies for over thirty years. In cases where the price per share went down and I had a loss and/or where the dividend went down I did one of two things. If I had confidence in the management of the fund I hung on and waited and eventually the fund went back up. In cases where I doubted if the management was doing the right thing I sold out at a loss and switched to another fund.
