Black Swans

Larry Leibowitz, the chief operating officer of NYSE Euronext says Electronic Trading to Blame for Plunge

Computerized trades sent to electronic networks turned an orderly stock market decline into a rout today, according to Larry Leibowitz, the chief operating officer of NYSE Euronext.

While the first half of the Dow Jones Industrial Average’s 998.5-point plunge probably reflected normal trading, the selloff snowballed because of orders sent to venues with no investors willing to match them, Leibowitz said in an interview on Bloomberg Television.

Plunge Raises Alarm on Computerized Trading

A spine-chilling slide of nearly 1,000 points in the Dow Jones Industrial Average, its biggest intraday points drop ever, led to heightened calls for a crackdown on computer-driven high-frequency trading.

The slide, which in one 10-minute stretch knocked the index down nearly 700 points, may have been triggered by a trading error. Major stock indexes eventually recovered from their 9 percent drops to close down a little more than 3 percent.

But the follow-through selling that pushed stocks of some highly regarded companies into tailspins exacerbated concerns that regulators can quickly lose control of the markets in a world of algorithmic trading.

"The potential for giant high-speed computers to generate false trades and create market chaos reared its head again today," Senator Edward Kaufman said in a statement.

"The battle of the algorithms — not understood by nor even remotely transparent to the Securities and Exchange Commission — simply must be carefully reviewed and placed within a meaningful regulatory framework soon."

Computers vs. Computers

In essence computers trading against computers decided at some point today to throw in the towel and not bid.

At some point (manual intervention?) they all decided to bid again, driving stock prices back up. This is what our stock market casino has become.

Lovely, isn’t it?

I have been waiting for this to happen and today it did. Supposedly, computer trading lowers volatility and bid/ask spreads for traders. Today we see that works until it doesn’t.

Most of the day Citigroup was erroneously blamed for the plunge. Citigroup was not to blame, flash-trading computers vs. computers with fake orders appears to be the culprit.

Elon Musk Takes Out $50 Million in New Loans, Mortgaging Five Homes

Courtesy of Zero Hedge

We were one of the very first to speculate that Elon Musk had mortgaged 5 of his homes in late January, when we highlighted research by an internet sleuth on Musk's personal financial situation. According to public records cited by Tesla skeptic EVent Horizon and laid out in a timeline on Sutori in late January, Elon Musk looked as though he had leveraged some of his personal real estate.
