Wall Street was expecting volatility today — the New York Stock Exchange once again invoked Rule 48 before trading opened in an effort to speed up and smooth trading at the market open. The 2007 rule means that designated market makers will not have to disseminate price indications before the bell, making it easier and faster to open stocks.

The Too Big To Fails were among the hardest hit in morning trading– Bank of America (BAC) was down 3.44% while JPMorgan Chase & Co. (JPM) was down 3.35%. Wells Fargo (WFC) was down 2.93%.

Nationstar Mortgage (NSM), meanwhile, was the biggest bleeder, down 4.83%.

Here’s a snapshot of where things stood 11:08 a.m. ET.
