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

Inquiring minds are reading Stock plunge raises alarm on algo 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.

Short Opportunity II

The first chance for a short play got burned but there is a second one on offer for the S&P.

The S&P tagged channel resistance and while today's reversal off resistance didn't amount to a big percentage loss it did register as a distribution day. There wasn't any significant technical change so if this short does evolve it will do so with risk measured on a move above 2,717.


The Nasdaq may match a 'bearish evening star' but if this is the case there has to be a significant move lower tomor...

A Starbucks manager in Philadelphia called the police on two black men on April 13, leading to their arrest. The two men, who had been waiting for a friend at the store, were released without being charged.

Starbucks has since apologized and announced it will close more than 8,000 of its stores in the United States to provide “racial bias” training for its 175,000 ...

Only 0.04% Of Taxpayers Are Reporting Any Bitcoin Gains To The IRS

Courtesy of Zero Hedge

With the US tax deadline just one day away, crypto investors who traded actively during the market's run-up and inevitable meltdown should have a lot of activity to report to the IRS.

But according to a survey conducted by Credit Karma, only a handful of people who have filed their taxes using Credit Karma's tools have reported bitcoin holdings or holdings of some other cryptocurrency - fewer than 100 out of a total of 250,000 filers, or a whopping 0.04% in total.

In all likelihood, this means that (tens of) thousands of bitcoin traders are refusing to pay the IRS, either betting on the anonymity of the blockchain to conceal th...

Buffett At His Best

By csinvesting. Originally published at ValueWalk.

Bear with me as I share a bit of my history that helped me create SkyVu and the Battle Bears games. The University of Nebraska gave me my first job after college. I mostly pushed TV carts around, edited videos for professors or the occasional speaker event. One day, Warren Buffet came to campus to speak to the College of Business. I didn’t think much of this speech at the time but I saved it for some reason. 15 years later, as a founder of my own company, I watch and listen to this particular speech every year to remind myself of the fundamentals and values Mr. Buffett looks for. He’s addressing business students at his alma mater, so I think his style here is a bit more ‘close to home’ than in his other speeches. Hopefully many of you find great value in this video like I have. Sorry for the VHS...

The Stock Bull Market Stops Here!

The definition of a bull market or bull trends widely vary. One of the more common criteria for bull markets is determined by the asset being above or below its 200 day moving average.

In my humble opinion, each index above remains in a bull trend, as triple support (200-day moving averages, 2-year rising support lines, and February lows) are still in play ...

The tricks propagandists use to beat science

Via Jean-Luc

How propagandist beat science – they did it for the tobacco industry and now it's in favor of the energy companies:

The tricks propagandists use to beat science

The original tobacco strategy involved several lines of attack. One of these was to fund research that supported the industry and then publish only the results that fit the required narrative. “For instance, in 1954 the TIRC distributed a pamphlet entitled ‘A Scientific Perspective on the Cigarette Controversy’ to nearly 200,000 doctors, journalists, and policy-makers, in which they emphasized favorable research and questioned results supporting the contrary view,” say Weatherall and co, who call this approach biased production.

A second approach promoted independent research that happened to support ...
