Today, one quarter of the volume in the market is attributable to trading in Citi shares. This is simply a ridiculous statistic, and shows that the broader equity market, which merely trades based on the momentum of one stock, is and has been busted for about a year, when we first wrote about this phenomenon. Yet this insane churn is not enough for some: The ISE has just announced it is introducing a "Modified Maker/Taker Fee Schedule" for the three most actively traded options products on its exchange: QQQQ, C, and BAC. In essence, the ISE will provide even greater rebates to "liquidity providers" in these three stocks. The entire market will soon consists of exactly two companies (both of which are wards of the state) and one ETF, as liquidity finds the path of least resistance and greatest (evaporating) profit margins. This is what "liquidity" in the market has become. And all the while, the latest DMM, GETCO, which is certainly not frontrunning its prop positions based on massive NYSE flow traffic, is laughing all the way to the bank.
