That's the recessive gene. These days Bob kills them off....he told me he missed one....and that he's still paying for it.
IMHO and very distant view, the Bright Trading acting CFO lineage is most likely something close to this: CEO Bob > Bob>Tammy > PRES (& acting COO!) Tammy > Tammy/Bob>Christy > CFO Christy. According to those who work with her on almost a daily basis, newly-named Bright Trading Chief Financial Officer, Christy Bright-Ross, is very astute also as trader. Congratulations Christy
I guess Christy is one of the few people in America who won't get in trouble on the job for sneaking in a few trades.
