Fast-Reading Computers Are About To Drink Your Trading Milkshake

Add speed reading to the set of mad skills that rich robotic algos are now much better at than humans. The latest craze among the computerized trading community is using Johnny 5 to read through thousands of press releases in combination with some fuzzy logic and the 80/20 rule, to trade stocks pronto, even as plain vanilla Homo Sapiens are still stuck on footnote 1. The WSJ reports that: "Researchers have been working on an artificial-intelligence computer program designed to mimic the way an analyst uses financial news. In simulated trading, the program beat the S&P 500, and when combined with quantitative stock-picking techniques, it saw a return on trades of more than 20%."

Unlike traditional number crunching methods to front run those armed with less than the latest SPARCs, this latest development will instead try to determine what the subtext of a given PR narrative is and trade it accordingly. It is unclear whether these programs are already in place, and whether they account for the almost universally wrong knee jerk reaction post any earnings and press release by public companies. We can’t wait for corporate counter-espionage divisions to reverse engineer these algos, and determine just what keywords and phrases set off Buy programs, and flood their press releases which announce 100% misses to expectations, yet result in flash dashes and inexplicably push stock prices up a few million percent. In other news, the market is now no longer about forecasting, predicting, and, generally, investing, but merely about being faster to frontrun/react/buy than your immediate competitor.

More from the WSJ:

To make stock predictions, the program does what is known as “text mining” — scanning large volumes of content and analyzing the words in it. Computer-aided quantitative funds already are plentiful, but they analyze numerical data rather than text. The new program is different because it attempts to simulate what has traditionally been a human activity.

“Our approach is more like the analyst approach, simulated by a program,” said Hsinchun Chen, director of the University of Arizona’s Artificial Intelligence Lab, in an interview with Digits. “You have an analyst reading papers, looking for clues that others have not observed.”

The program, which was first reported by MIT’s Technology Review, scans stock prices and financial news and buys

Help One Of Our Own PSW Members

"Hello PSW Members –

This is a non-trading topic, but I wanted to post it during trading hours so as many eyes can see it as possible.  Feel free to contact me directly at jennifersurovy@yahoo.com with any questions.

Last fall there was some discussion on the PSW board regarding setting up a YouCaring donation page for a PSW member, Shadowfax. Since then, we have been looking into ways to help get him additional medical services and to pay down his medical debts.  After following those leads, we are ready to move ahead with the YouCaring site. (Link is posted below.)  Any help you can give will be greatly appreciated; not only to help aid in his medical bill debt, but to also show what a great community this group is.

http://www.youcaring.com/medical-fundraiser/help-get-shadowfax-out-from-the-darkness-of-medical-bills-/126743

Thank you for you time!

The mass demonstrations in Hong Kong are dramatic, indeed. And given that Hong Kong has long enjoyed a more liberal existence under British rule, protests against a more authoritarian Chinese government (at least ...

Here's The Best Explanation We've Seen Yet For Why Oil Crashed

Here's The Best Explanation We've Seen Yet For Why Oil Crashed

Courtesy of 

Oil crashed today, with crude oil prices dropping from around $95 to $91 in a matter of minutes.

There were various theories for why, but the most compelling one is that there seems to be a lot more production than estimated.

Morgan Stanley sent out a note this evening from analyst Adam Longson that contains this table of production numbers/estimates for key producers. The key thing is that production is on the rise almost everywhere. Check out Libya, where output for the month surged to its highest level of the year. Everyone was freaking out a...

Moving Averages: Month-End Update

Valid until the market close on October 31, 2014

The S&P 500 closed September with a monthly loss of 1.55%. All three S&P 500 MAs and three of the five the Ivy Portfolio ETF MAs are signaling "Invested".

The Ivy Portfolio

The table below shows the current 10-month simple moving average (SMA) signal for each of the five ETFs featured in The Ivy Portfolio. I've also included a table of 12-month SMAs for the same ETFs for this popular alternative strategy.

Option Review

VIX Call Spreads Trade

The CBOE Vix Index topped 17.0 and the highest level since early-August on Monday morning amid declines in U.S. equities to start the trading week. The volatility index is off its earlier highs to trade 5.0% higher on the session at 15.65 as of 11:30 am ET. Options volume on the VIX is hovering near 360,000 contracts, or just more than 50% of the average daily reading of around 660,000 contracts. Calls are far more active than put options, as evidenced by the call/put ratio up above 4.2 in morning trading, perhaps as some traders position for volatility to stick around.

Large call spreads traded on the VIX today caught our attention as one big optio...

Sector Detector: Stocks fight off predictable weakness, but expect more downside

Courtesy of Sabrient Systems and Gradient Analytics

Yes, the market showed significant weakness last week for the first time in quite a while. In fact, the Dow Jones Industrial Average moved triple digits each day. But it was all quite predictable, as I suggested in last week's article, and certainly nothing to worry about. Now the market appears to be poised for a modest technical rebound, and longer term, U.S. equities should be in good shape for a year-end rally. However, I still believe more downside is in order before any new highs are challenged. Moreover, market breadth is important for a sustained bull run, so the challenge for investors will be to put together broader bullish conviction, including the small caps.

In this weekly update, I give my view of the current market environment, offer a technical analysis of the S&P 500 chart, re...

Ebola vs. Us

Ebola vs. Us

By Ilene 

Ebola is spreading too quickly for Ebola-vaccine makers to conduct typical studies of safety and efficacy on experimental vaccines. Instead, vaccines will be tested for basic safety, but then deployed with protocols devised now in order to test for efficacy essentially on the field. Testing has to be expedited because the situation in West Africa gets worse every day while there are no approved vaccines or other treatments.

The chart below is from a paper in the New England Journal of Medicine showing estimates of the virus's trajectory projecting out to November 1, 2014. If current trends continue...

Making Sense of Bitcoin

Making Sense of Bitcoin

By James Black at International Man

Despite the various opinions on Bitcoin, there is no question as to its ultimate value: its ability to bypass government restrictions, including economic embargoes and capital controls, to transmit quasi-anonymous money to anyone anywhere.

Opinions differ as to what constitutes "money."

The English word "money" derives from the Latin word "moneta," which means to "mint." Historically, "money" was minted in the form of precious metals, most notably gold and silver. Minted metal was considered "money" because it possessed luster, was scarce, and had perceive...

Biotechs & Bubbles

Reminder: Pharmboy is available to chat with Members, comments are found below each post.

Well PSW Subscribers....I am still here, barely.  From my last post a few months ago to now, nothing has changed much, but there are a few bargins out there that as investors, should be put on the watch list (again) and if so desired....buy a small amount.

First, the media is on a tear against biotechs/pharma, ripping companies for their drug prices.  Gilead's HepC drug, Sovaldi, is priced at $84K for the 12-week treatment.  Pundits were screaming bloody murder that it was a total rip off, but when one investigates the other drugs out there, and the consequences of not taking Sovaldi vs. another drug combinations, then things become clearer.  For instance, Olysio (JNJ) is about $66,000 for a 12-week treatment, but is approved for fewer types of patients AND...
