Science, Stocks and Superstition

biasesUnreliable Science

As we’ve seen – repeatedly – people aren’t particularly good at overcoming the behavioural biases built into our nature by evolution. There’s no real reason we should be – computing the statistical probability of an above average return on the stockmarket over a twenty year period wasn’t of much value for most of human history. This was partly because twenty years was more than the average lifespan of a proto-human but largely because no one had yet got around to inventing money or stockmarkets or stocks. Or ‘years’.

If these biases are inherent and cause us to do stupid things around finance we might expect that they’ll appear in other areas as well where humanity has only recently started to apply its higher cognitive functions. So it’s unsurprising that our basic intuitions about science are about as reliable as those we have about finance. To whit: not reliable at all.

Greek Geeks

Science has been around a lot longer than modern financial theory. The Ancient Greeks developed many concepts that aren’t out of place in the modern pantheon of university science faculties – atomic theory, planetary orbits and toga parties amongst them. Unfortunately they failed to marry their scientific insights to a stable economic system and much of their knowledge was lost for the best part of a millennium. The lesson being, presumably, that disenfranchising women and relying on slave labour is a poor way of building a stable society. Global corporations take note.

GreeksDuring that lost thousand years or so the only real legacy of Greek knowledge in the Western world was a smattering of Aristotle, who was a bloody good thinker but a bit weak on stuff like planetary motion and mathematics. Somewhere along the line Aristotle’s ideas got mixed up with Christianity and resulted in the odd position of the Catholic Church defining God’s word on the basis of the scientific writings of an atheistic Greek who died before Christ was born. We can blame Thomas Aquinas for that one.

The period known as the Renaissance – the rebirth – was marked by a remarkable rediscovery of Ancient Greek thought. Some of this came from the Muslim world, where many ideas and writings had been sustained through the European Dark Ages, and some of it from the

The Real Story Behind Goldman's Q2 Trading Loss: How A $100M Gas Bet Went Awry

Goldman Sachs FICC-trading income was an unexpectedly ugly blemish on what was already a poor Q2 earnings report. And while the FDIC-backed hedge fund initially blamed the decline on lower trading revenues, lack of volatility and depressed client activity...

The Entire Medical Industry Is About To Change

By The Sovereign Investor. Originally published at ValueWalk.

The doctor straightened and pulled the stethoscope from her ears. “I don’t hear anything on the right side.”

Sometimes silence is a good sign. When it comes to listening to my husband breathing, it’s not.

One quick X-ray later and we discover that his right lung had collapsed. There was also air putting pressure on his left lung.

The fix was easy. The doctor inserted a slender tube into his chest, sucking out the air. His lung reinflated in a matter of minutes.

I caught the doctor later and asked her why this had happened. When the pain started, he’d been watching TV.

She shrugged and admitted that sometimes it was just something that happened to men who are tall and thin.

Of course, the answer to the question of “How do we avoid this?”...

Investment Advice in Four Words: Have Patience, Avoid Bubbles

Courtesy of Mish.

A relations manager for Ted Thomas reached out last week and asked: “What is your most valuable advice to people who are beginner investors so that they can get great results in the long term?”

The answer form had no formatting options. Here is a detailed response, with links.

Have Patience, Avoid Bubbles

The TINA theory (there is no alternative other than stocks and bonds) is a path to poor returns.

Cash and gold are indeed options. I discussed TINA in Median Price-to-Revenue Ratio Higher in All Deciles vs 2007, 90% vs Dot-Com Bubble: THE Choice

Volatility on the Rise

Courtesy of Declan.

Today's losses look big on current charts but in a historic context, they weren't too severe. However, big red bars are not to be ignored and 'market leading' Small Caps have felt the full brunt of the selling from July which is bad news for the broader market.  Today's losses in the Russell 2000 undercut the 200-day MA leaving 1,345 as next support (of which I would not be too confident of it holding).


If the Russell 2000 gives up 1,350s then a drop to 1,150s could be on the cards. Things could get ugly if this scenario pl...

Ukrainian Lawmakers Disclose $45 Million In Bitcoin Holdings

Courtesy of ZeroHedge. View original post here.

As Ukraine's crackdown on corruption continues, three lawmakers from Ukraine’s ruling party revealed this week that they own a combined $45 million in bitcoin, according to a report by RIA Novosti, a Russian foreign news service.

Their holdings came to light during mandatory financial disclosures by members of the Ukrainian parliament, part of an IMF-approved strategy to tamp down corruption in Ukraine. The country's democratic institutions, which were never very robust to begin with, have been further destabilized by...

The App Economy Will Be Worth $6 Trillion in Five Years

This would be excellent news for AAPL and GOOG to a lesser extent although not inconsequential:

The App Economy Will Be Worth $6 Trillion in Five Years 

In five years, the app economy will be worth $6.3 trillion, up from $1.3 trillion last year, according to a report released today by app measurement company App Annie. What explains the growth? More people are spending more time and -- crucially -- more money in apps. While on average people aren't downloading many more apps, App Annie expects global app usership to nearly double to 6.3 billion people in the next five years while the time spent in apps will more than double. And, it expects the...
