I send out several tweets daily on as many of those that I can find @billgunderson. Blackstone is in a healthy uptrend, it's in the right sector, a top performer over the years, and it passes my valuation test. When I compare Blackstone against all of the other stocks that I follow, it comes in at No. 246 overall and earns a Gunderson Grade of "A-." (I buy only stocks that are ranked "A-" or better.) As always, there are no guarantees in the stock market. Even though I am long this stock, it is part of a well-diversified portfolio that is managed every day.
