FYI:
Don't stress too much about stocks losing rank and what is the official final universe.
I keep pace with Spydertrader's final universe and I also maintain my own list of stocks that include virtually every stock that has been a member of the universe at one time or another (plus some others). My list, call it my Plan_B list, has roughly 310 stocks.
Every AM prior to market open, I run the DU 3 month chartscript that everyone else has, via wealthlab. The list of DU stocks it returns for the official final universe and the Plan_B list is almost always the same. When there are more stocks via the Plan_B list, I'm usually able to quickly disregard them via a casual glance at the chart. If I can't instantly dismiss them then they go into a secondary watchlist for the day, with the primary watchlist being the official Hershey DU stocks for the day.
In conclusion, don't worry too much if your official universe list is missing a stock or two, or has one or two more than it should. 99 percent of the time you'll match everyone else after you get to DU.
