Shares of Interactive Brokers (IBKR) - Get Report are down 14 percent thus far in 2016, but the electronic broker and market maker will see its fortunes turnaround as it captures market share from its larger rivals, said Jim Sanford, portfolio manager at Sag Harbor Advisors. 'Interactive Brokers should steal more and more market share from Fidelity and TD Ameritrade as more savvy investors and fee-only advisors become cognizant of its superior technology and lower fees,' said Sanford. Earlier this week Interactive Brokers Group on Tuesday reported second-quarter net income of $27 million, or $0.40 a share, on revenue of $369 million. The results surpassed Wall Street expectations of $0.35 a share. Sanford is also bullish on Charles Schwab (SCHW) - Get Report , down 16 percent year-to-date, saying it has 'significant room to grow assets.' Earlier this week the brokerage company posted second quarter earnings of $0.30 a share, which matched analysts' projections. Revenue rose 17 percent to $1.83 billion from last year and was slightly above Wall Street's estimates of $1.8 billion.
