OMAHA, Neb. (AP) — Online brokerage TD Ameritrade says the number of stock trades it handled in May declined slightly but the amount of client assets it held grew over last year.

The Omaha-based Ameritrade said Thursday it handled an average of 370,000 client trades per day last month. That’s down 2 percent from last May, but up 1 percent from April 2012.

Ameritrade generates revenue from fees it charges on the transactions it handles and from fees on client assets in certain accounts. The company’s monthly data also offers clues about overall investor sentiment.

Ameritrade says the amount of client assets it held grew 3 percent from last year to $431.7 billion at the end of May. But that figure was 4 percent lower than the April 2012 total.
