Schwab, Interactive Brokers, Robinhood fall on July 29

Schwab fell 4.1% to $105.96 after touching a high of $106.72, while Interactive Brokers slipped 3.9% to $87.28 and Robinhood lost 2.5% to $90.47. All three names remain well above their 200-day moving averages, but the latest moves show how quickly enthusiasm can fade when investors question the durability of growth after a powerful rally earlier this year.

For Schwab, the shares are still up more than 17% from the May low of $89.44 and have reclaimed the 50-day moving average, but the stock is now just above the upper end of its recent Bollinger Band and its RSI is easing from overbought territory. Interactive Brokers has also given back part of a strong advance from the spring, while Robinhood has fallen back below its 50-day moving average after a sharp summer run that briefly pushed it above $117.

The broader message for investors is that discount brokerage is no longer just a story about cheaper trades. The winners are the firms that can offset fee compression with higher net interest income, larger customer balances, derivatives and margin usage, and the losers are those that rely too heavily on trading volumes staying hot.

That makes the next round of earnings, client asset trends and rate expectations the key catalysts for the group. If activity stays strong and cash balances hold up, the selloff could prove temporary; if not, the market is likely to keep separating platform scale from pure trading momentum.
