The Madness Behind Interactive Brokers’ 6% Plunge

Tuesday night-the witching hour for Wall Street-Interactive Brokers threw a little announcement on the wire: They were launching their IBKR Lite pricing plan in Singapore. And just like that, the stock took a dive into the abyss. The claim? No commissions for trades on U.S. markets for users in Singapore. Sounds like a sweet deal, doesn’t it? Well, maybe too sweet, like one of those candy bars wrapped in health-conscious slogans but stuffed with enough sugar to make your pancreas turn on you.
