For example: AFFX, BDBD, CTCT, CYBX, DMND, DYAX (and there are quite a few more). Assuming these companies haven't all been spun out again, it looks like there's a bug in the code that generates the symbol list.

With the exception of LMKRP, none have updated. At first glance seem to have been sent in error. All invalid symbols will be removed.
