Per an article on eBay at The Street, $42.01 - $2.51 = $29.50. Ouch! I hate to have this person as my financial adviser. Here's the blurb (I'm sure they'll be correcting this today):
Shares of eBay rose $1.59 during regular action Wednesday to $42.01 before reversing course after hours. On Instinet Thursday, they were off $2.51 to $29.50.
