The process of identifying a great company, and purchasing it at an attractive price is part art, part science. While I have tried to narrow it down to a few quantitative factors, my detailed analysis of each company could bring an unexpected turn of events in determining qualitative nature of things.
In reality, once you have purchased shares of a quality company at fair prices, your job is done. You should stop checking the quote page every five minutes, and turn off your computer. Collect your dividends, and pick up a hobby. And please, listen to your wife and take the Christmas lights off. It is April after all.
This is contrary to what everyone else is telling you to do. You have been told that buy and hold means buy and monitor. And this could be true to a certain extent. However, over the course of a year, there could typically be only a few material events that could impact your analysis of a dividend paying company. One of them would be what is in the annual report, another could be the rate of change in dividends, while a third could be related to corporate events such as mergers, spin-offs, etc.
