Only 1 stock among the set of 310 CRSP stocks we have, of which we currently use 300, and this causes problems.
In addition it turns out that there are only 2 or 3 stocks among the 310 in the Utilities Sector.
I propose that we replace these stocks with some from the additional 10 that are in other sectors.
It would be best to do that at the same time the additional 50 GICS codes are added, along with the corresponding Sectors.
