How your brain remembers the future

Déjà vu, all over again.

How your brain remembers the future

Image Of Thinking Man's Brain Through Bowler Hat

By NewScientist

IT’S like remembering the future. Our brain generates predictions of likely visual inputs so it can focus on dealing with the unexpected.

Predictable sights trigger less brain activity than unfamiliar stimuli, bolstering the view that the brain is not merely reactive, but generates predictions based on the recent past. "The brain expects to see things and really just wants to confirm it now and again," says Lars Muckli at the University of Glasgow, UK.

[...]

The finding supports the "Bayesian brain" theory, which sees the brain as making predictions about the world which it updates when new information comes in.

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.

Thank you for you time!

The 10th Man: Midterm Elections: Would a Republican Win Be Bullish for the Stock Market?

The 10th Man: Midterm Elections: Would a Republican Win Be Bullish for the Stock Market?

By Jared Dillian

I had an instant-messenger conversation with one of my clients the other day. It was pretty annoying—he wrote things like “BULL MARKET, DUDE,” and harangued me about my net-short positioning.

Then he started telling me that the market was going to rip if the Republicans took both houses of Congress in the midterm elections. At that point, I felt like I needed to intervene.

First of all, just about every single piece of academic research on the subject shows that the stock market (and GDP, and many other metrics) outperforms under Democratic presidents.

You don’t need to look very far for a contemporary example, considering that the stock market has done a three-bagger under our current leader, and the economy has recovered. ...

Submitted by Martin Armstrong via Armstrong Economics,

Reuters has published the result of what is being touted as the Ignorance Index. The one question as an example: “Guess how many U.S. girls aged 15-19 give birth each year. Go ahead, guess. If you calculated the number at 3 percent you’re correct; if you guessed 24 percent, you’re American.”

Sector Detector: Bullish conviction returns, but market likely to consolidate its V-bottom

Courtesy of Sabrient Systems and Gradient Analytics

Bulls showed renewed backbone last week and drew a line in the sand for the bears, buying with gusto into weakness as I suggested they would. After all, this was the buying opportunity they had been waiting for. As if on cue, the start of the World Series launched the rapid market reversal and recovery. However, there is little chance that the rally will go straight up. Volatility is back, and I would look for prices to consolidate at this level before making an attempt to go higher. I still question whether the S&P 500 will ultimately achieve a new high before year end.

In this weekly update, I give my view of the current market environment, offer a technical analysis of the S&P 500 chart, review our weekly fundamentals-based SectorCast rankings of the ten U.S. business sectors, and then o...

Option Review

LUV Options Active Ahead Of Earnings

There is lots of action in Southwest Airlines Co. November expiry call options today ahead of the air carrier’s third-quarter earnings report prior to the opening bell on Thursday. Among the large block trades initiated throughout the trading session, there appears to be at least one options market participant establishing a call spread in far out of the money options. It looks like the trader purchased a 4,000-lot Nov 37/39 call spread at a net premium of $0.40 apiece. The trade makes money if shares in Southwest rally 9.0% over the current price of $34.32 to exceed the effective breakeven point at $37.40, with maximum potential profits of $1.60 per contract available in the event that shares jump more than 13% to $39.00 by expiration. In September, the stock tou...

Goodbye War On Drugs, Hello Libertarian Utopia. Dominic Frisby's Bitcoin: The Future of Money?

Courtesy of John Rubino.

Now that bitcoin has subsided from speculative bubble to functioning currency (see the price chart below), it’s safe for non-speculators to explore the whole “cryptocurrency” thing. So…is bitcoin or one of its growing list of competitors a useful addition to the average person’s array of bank accounts and credit cards — or is it a replacement for most of those things? And how does one make this transition?

With his usual excellent timing, London-based financial writer/actor/stand-up comic Dominic Frisby has just released Bitcoin: The Future of Money? in which he explains all this in terms most readers will have no tr...

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...
