Do You Like Scary Movies?



You're watching a movie - a thriller actually. You just don't think of it that way.

You laugh at the happy parts. Lose interest a bit during the slow parts. And occasionally, when there's a plot twist... it scares the living hell out of you. The funny thing is you actually know how it's going to turn out in the end. But that doesn't stop you from "getting into" it.

The movie is, "The Market" and it show times are M-F, 9:30 AM through 4 PM (EST).

Okay. It's not technically a movie. Nobody's selling $8 popcorn and it doesn't have Ben Affleck in it or anything (thank God), but a movie is a good way to think about your investments from a psychological perspective.

Take James Bond movies, for example. When we watch a Bond flick, we know what we're getting into. He's going to use some cool gadgets, drink a martini, save the world, "get the girl", etc.

But at certain times during the film, there are moments in which 007 is in mortal peril (inordinately involving buzz saws, lasers, and exotic predatory animals). If we've been following along, if we're "into it", we experience an unavoidable emotional reaction - anxiety, or as the movie business euphemistically dubs it, "suspense".

We can't help it. We experience this supense because we follow the story not just with our eyes, but with out brains, and that means we follow it on an intellectual and an emotional level.

In fact, it's almost as if our emotional brain and our intellectual brain watch the movie on a couch together and during the suspenseful parts, wrestle for control of our head.
Sometimes the conversation looks like this. (Watch the following classic clip from Goldfinger to really provide the context.)

Emotional Brain (EB): HOLY CRAP! THE LASER IS GONNA SAW HIM IN HALF! THERE'S NO WAY HE CAN ESCAPE!!

(Note: The Emotional Brain not only speaks in exclamations, it uses all "caps".)

Intellectual Brain (IB): I say, get a grip, lad! It's a half an hour into a 3 hour movie. He'll be fine. Stiff upper lip and all that.

(Note: The Intellectual Brain is not only the voice of reason, it has a 19th century British accent.)

EB: BUT, BUT! HE CAN'T REACH HIS MAGNETIC PEN KNIFE!!! HE'S SCREWED!! AAAUUUGH! I'M HYPER.. VENTILATING...!!

IB: Yes, yes. Dire straits, indeed. But we know full well that Daniel Craig signed a 3 movie deal. Can't just dispatch him in the first one, now can we? Wouldn't be cricket!

EB: ARE YOU NUTS?? ARE YOU BLIND?? THE LASER IS ALMOST UP TO HIS - OH, MY GOD, I CAN'T EVEN SAY IT! MAY DAY! MAY DAY! MAY

IB: - All right, all right, lad! I suppose a bifurcated John Thomas is more than you can bear. No talking you out of it, this time. I'm going to send a neuro signal to the hands to cover your eyes... now. And hand me those pretzels, old boy. You're getting crumbs all over the floor and I just had it cleaned yesterday, don't you know.

EB: SORRY!!

Now, it should be said, we have enough data on James Bond and on the major market indexes to know what happens in the long run. But when we're watching the movie, we're not in the long run. We get drawn into the emotions of the moment and we struggle, sometimes in vain, to restore a big picture perspective.

The above conversation is essentially what our psychological defense mechanisms look like when we watch a movie or when we watch The Market. The tactics are certainly the same. Get us out of the "moment" (short term) and refocus on the big picture (long term). Supplant emotion with reason, fear with facts.

And sometimes when we can't reframe from a short-term to a long-term perspective, we simply cover our eyes (i.e., stop watching). It's an excellent last resort tactic that is underutilized.

So enjoy your thrillers, if that's your thing. And enjoy your Market watching. But remember what it is your watching, and retain that ability to pull yourself up out of that short-term emotional tailspin. Because you will get draw in and it will happen without your awareness (just like in a movie).

And if you insist on watching scarey movies, in the name of Freddy Krueger... do NOT watch them alone.

Happy investing.

NOBODY EXPECTS THE SPANISH INQUISITION!!!



My home page is the Yahoo! Finance page. There are two reasons I chose it: 1) If I want to check a stock price, or market action, I can do so with just one click; 2) The pre-market headlines crack me up.

Go ahead, check them out yourself one day. You will find that they are generally rendered moot/outdated/incorrect within the first hour of trading.

Look, I'm trained as a psychologist. I look at things differently. It probably makes me a "bit of an odd duck", to borrow a phrase from my father. (It's true. Ask any of my remaining friends.)

But you don't need to be the quirky type to see why this (lead) sentence from the pre-market headline article is just silly.

"The number of newly laid off workers filing claims for unemployment benefits unexpectedly rose last week as the recovery of the nation's battered labor market proceeds in fits and starts."

What's wrong with this sentence? Well for starters it notes that unemployment claims rose "unexpectedly" last week. Later on in the same sentence, it notes that the labor market "proceeds in fits and starts."

First of all, all economic forecasting is incredibly complex. Why a rise of 1% rather than a decline of 1% for one lousy week's worth of data rates as a "surprise" is beyond me. It's like standing in a rain shower and saying you got hit by a particularly unexpected raindrop. (Really? Didn't see that one coming??)

But the second clause of the sentence says the market proceeds in "fits and starts". Yes, it does. Truly. It is a point that is universally acknowledged. So how can you be suprised by a slight decrease while simultaneously noting the market proceeds in a herky jerky fashion?

For crying out loud, pick a side and stick with it!

Behavioral finance research has taught us how rarely data conform to our pre-supposed parameters. We know a coin will come up heads 50% of the time. Yet somehow we find ourselves wanting results to alternate heads/tails when we flip it. We see a run of 3 or more heads in a row, our pattern-seeking brains screams, "anomaly!"

It's not an anomaly. It is the essence of randomness.

Back to the article; if you read it in its entirety, you will see just how complex the jobs data are. You will find yourself wondering if the first paragraph still makes sense by the end of it.

The skinny: When it comes to a week's worth of economic data, market movements... the weather, don't "expect" anything.

It is sillyness that calls to mind this famous bit of sillyness .

I'm going to have my coffee now.

(Entirely too much sillyness.)

The Value of the Time Out


In the words of Dick Vitale... "Get a T.O., Baby!!"

The value of the time out to the investor and investors plural (i.e., "the market") is hard to exaggerate.

Whether it's FDR's famous "Bank Holidays," or suspended trading, or simply going for a long walk when you're tempted to make an impulsive trade, the "time out" is a major weapon in an investor's fear-fighting aresenal.

Why? Because fear FORCES us to think short term. It's simply the way our brains are wired. There is a sound biological/evolutionary reason behind this reaction.

When you're out gathering firewood for the cave and lock eyes with a large male Smilodon (read Sabretooth Tiger) who has just emerged from the glade, your brain simply CANNOT LET you indulge in thoughts like "what to wear to Zog's birthday party?" or "should I redo the cave paintings for the harvest season (antelopes are so "early pleistocene")?"

The Sabretooth has gone the way of the Dodo, but the evolutionary function remains. Intense fear still draws our focus on the here and now. As well it should.

This is where the time out can help. The ablility to take a break and regain our bearings (to "step out of the box" as Crash Davis would say) gives our amydalas a chance to stop firing. When that happens we can engage other parts of our brain. That's when we can pull up and out of the tailspin of panic. It's neurobiology. See Rich's critically acclained tome for more information.
This is, of course, the eternal struggle for investors: To pull out of the short-term focus and think big picture.

When we do calm our brains and revisit the situation, it doesn't mean our outlook becomes rosy. It just means we've given our brains the ability to reintroduce reason to our thinking processes - and perhaps a chance to spot the fantastic opportunities such crises produce.

A few days off may be just what the doctor ordered.

In the meantime, good luck out there, everyone.
