The company recorded net new assets (brought by existing as well as new clients) of $1.3 billion, down 86% from the comparable period a year ago and 90% from the preceding month. The plunge was largely due to client cash disbursements during the tax season.Total client assets were $2.58 trillion, up 1% year over year and 1% sequentially. Additionally, client assets receiving ongoing advisory services totaled $1.29 trillion for the month, up 2% year over year and 1% from the prior month.At the end of Apr 2016, Schwab’s average interest-earning assets amounted to $183.3 billion, up 20% from Apr 2015 and 1% from Mar 2016.Schwab opened 103,000 new brokerage accounts in Apr 2016.

Net buy activity in Exchange Traded Funds was $1,994 million as against $2,993 million in Apr 2015 and $2,336 million in Mar 2016.Schwab remains well positioned to benefit from the anticipated gradual rise in interest rates and improved client confidence as well as diversified revenue streams, enhanced equity markets and management’s efforts to boost the client base in advisory solutions. However, the company’s elevated expenses, sensitivity to interest rates and significant dependence on fee-based revenue streams continue to be matters of concern.Currently, Schwab carries a Zacks Rank #3 (Hold).Among other investment brokers, TD Ameritrade Holding Corporation AMTD reported average client trades of 470,000 per day in its activity report for Apr 2016.
