Seems to be a problem with TCAP between Nov 2009 and Nov 2010.

You are right, from 10/24/09 - 10/9/10
Investigating. Thanks
Looks like TCAP security was classified as ‘investment trust fund’ by Compustat in that period (which we ignore), then went back to being common stock. I rebuilt the historical data and should be ok by tomorrow.
Thanks
