Very weird activity has happened at the NYSE today.
It started not long before 10:00 AM, when people noticed some very volatile action in a select list of stocks. Volume was ginormous.
Right off the bat, people suspect some kind of algorithmic trading fiasco.
Word quickly spread through the trading community that the issues were centered around Knight Capital, a market maker.
Shares of Knight Capital, the market maker, immediately got slammed. They’re down nearly 11% now 24%!. People think the technical issues are originating from them.
You could easily see the stocks taking weird, glitchy swings.

CNBC is reporting that Knight Capital is not commenting, but that traders are all still pointing at Knight Capital.
NANEX has sent us this fantastic chart, which shows the bid and the ask in one stock (a utilities ETF), and how at first the bid/ask are tight, but then just before 10:00 AM went totally wild.
The NYSE is apparently reviewing trades in 148 securities between 9:30 and 10:15. This was reported by Bloomberg TV’s Josh Lipton and confirmed by Business Insider.
According to Bloomberg, Knight Capital has now told clients to trade elsewhere, seemingly confirming that there’s a problem there.
The NYSE has officially announced the names of the 148 companies that were, including Alcoa, GM, and Bank of America.
Knight just released a statement about the issues to Business Insider, here it is:
“An initial review by Knight indicates that a technology issue occurred in the company’s market-making unit related to the routing of shares of approximately 150 stocks to the NYSE. Knight notified its market-making clients this morning to route listed orders away. The company’s OTC securities and trading in its other businesses are not affected. The company continues to review internally.”
Sources within the NYSE tell Business Insider that its systems are functioning normally and that the Retail Liquidity Program, which launched today, is also running as expected.
The NYSE has just issued a statement to Business Insider, here it is (emphasis added):
