I send out several tweets daily on as many of those that I can find. Follow me @billgunderson. Watsco is in a healthy uptrend, and it possesses the other two criteria that I demand: performance and value. When I compare Watsco to all of the other stocks that I follow, it ranks No. 35 overall and earns a Gunderson Grade of "A." As always, there are no guarantees in the stock market. Even though I am long this stock, it is also part of a well-diversified portfolio that is managed every day.
