I think it is most important to determine your own approach and stick to it, as that is the best way to ultimately be successful in investing. Otherwise you are adrift without a rudder and will ultimately for sure make a mistake and not even realize you are making a mistake.
However, for me and the non-rules follower that I am , I sold my shares in NS, thankfully in time has since imploded due to a decline in it's asphalt business, VFC which is a company I like very much but in valuation of dividend returns I let it go, AMGN same story, KMP, VVC a nice Indiana utility company I sold due to needing to sell something to get down by 50% and the dividend growth rate of VVC was the lowest in my portfolio. I kept MO, CHV, KO, ACN, and MCD.
With the proceeds, I used 5% of the total to increase my holdings in gold and silver, not because I think it is a great time to buy but merely to get my precious metal holdings in range with where I would like them and for now have the remainder in cash. If nothing comes up that I like I guess I'll be living on a 2.5% withdrawal rate, basically the same as the S&P500 dividend rate. But I would be very surprised if some good opportunities do not arise in the next couple of years before I retire.
