I rolled my 401K into my IRA when I retired, in March 2012. Since then I have done a lot of reading, about dividend investing. I made a (Yahoo) portfolio of companies I would follow. These are mostly Dividend Champions. When a stock price, on my list, gets near a low, I consider buying. When the price of a stock I own gets near a yearly high, I sell. This strategy served me well from March 2012 until January 2013, because stocks stayed in a narrow range. I did not 'Dollar cost average', because I felt confident of the direction of the stock I was buying. This strategy stopped working, with the sustained rally that started in January 2013. I find that my portfolio contains those stocks that didn't participate in the rally, and more cash on the sidelines than I intended. To nibble my way back into the market, at these prices, I am dollar cost averaging. But I'm also sitting on some cash in case the market goes back down.
