USStock Missing Securities?

In compiling my data, I realize the following securities have no data in the USStock daily or minute databases, and naturally don’t exist in the SecurityUSStock security master database either. Is this an unexpected problem that can be fixed, or do I need to look elsewhere for this data? Note that these securities do exist in Alapca security master.

This seems to be more or less a duplicate of your other post.

@brian how is this a duplicate? These are specific Sids that were collected, yet no data appears available for in the USStock data. These are not the Sids shown in the other post, these are real companies that I’ve traded in the past.
