TD Ameritrade jumps on Scottrade rumor

• A Bloomberg story last night said Scottrade is working with an adviser on a sale that would value the company in the $4B range.
• Among those with interest is TD Ameritrade (AMTD +5.2%), according to the story. With the industry struggling with sluggish trading volumes, low interest rates, and lower-cost rivals, a purchase would give Ameritrade the opportunity to profit by eliminating redundant back-office systems while bringing in new customers, says Bloomberg's David Ritter.
