Gamblers ‘Nonymous

Investing is, up to a point, gambling. Most of us don’t think of it in that way but if we conceive of the universe of stocks as a gas of randomly moving particles buffeted this way and that by forces largely beyond their – and certainly beyond our – control then there’s no other conclusion that can be drawn.

However, we don’t really believe this. What we generally believe is that although randomness is pervasive in stocks there’s a pattern that lies beneath the surface which we, in spite all evidence to the contrary, can pick out. For the idea that there are repeatable patterns hidden within apparently random games of chance we can thank one of our more unlikely heroes. Meet Girolamo Cardano, medieval physician, professional gambler and mathematician extraordinaire.

God’s Will

For a very long time in human history there was no appreciation or investigation of probability, the mathematics that lies behind assessments of risk. For the most part people didn’t believe in chance: stuff happened and that was God’s will. The idea that there was some order in the chaos either seems not to have occurred or to have been literally unthinkable.

Fishing hook with die

Gamblers, however, did have some vague understanding that there were patterns in the randomness and quite a lot of self-interest in figuring these out. It’s no surprise that gambling figures quite large in early accounts of advances in probability theory. In Cardano, who seems to have been addicted to gambling, the will to understand and the ability to do so came together.

Elementary Probability

In many ways what Cardano figured out is today regarded as almost trivial, but at the time it was revolutionary and it allowed him an insight into why and when he should take a risk and when he shouldn’t. Perhaps the simplest example is to do with dice. At the time it was regarded as a bit of a mystery why, when three dice were rolled, the sum of face-up numbers came to ten more often than nine, despite the fact that there were six ways of summing possible numbers to both.

The answer to this conundrum is almost childishly simple to our eyes. There are twenty seven ways of combining the possible sums to ten while there are only…

Citigroup Shutters Retail Options Market-Making After Losing War Against HFTs

Courtesy of ZeroHedge View original post here.

Anyone following market dynamics in recent months would have been left with the impression that whereas other securities may have had a rather somnolent third quarter, option market makers would be printing cash hand over fist, thanks mostly to the recent boom in retail call option buying, which as shown in the chart below, has seen nearly a doubling in option trading volumes in the past few months and hitting a record 18.4 million in August.

SPACs are still bulls***

 

SPACs are still bulls***

I almost slipped and bought into the SPAC Renaissance. Almost.

Draftkings looks legit. But Draftkings could have been a true IPO. The SPAC wrapper was beside the point. Chamath and Ackman will probably do something legit, those guys usually find a way to win. Maybe a few others. The rest are / will be garbage. My first impression was right.

Nikola’s stock has now fallen from near 100 down into the 20’s as the guy’s whole story has unraveled. Then the guy stepped down and ran away. None of this had to happen. But Nikola arrived on the markets as the quarry of a Special Purpose Acquisit...

FDA's New Standards On Coronavirus Vaccine

WASHINGTON, D.C. (September 23, 2020) -  In an effort to repair its badly damaged reputation, and convince the public that they should take any vaccine it authorizes, the FDA is issuing new standards, but they probably will not convince either experts nor the public that it will be safe and effective, says public interest law professor ...

Is Gold/US Dollar Ratio Sending Bearish Signal To Precious Metals?

Courtesy of Chris Kimble

Last month, I featured this Gold / US Dollar ratio chart in an article warning of the potential for a trend reversal.

While the broader bullish trend is still intact (higher lows since 2015), it could be time for Gold to take a breather.

Looking at today’s “updated” chart, we can see that the ratio formed a “doji star” candle last month with momentum running at peak levels (concerning). And this month we are seeing follow through to the downside (in the form of a red candle).

As well, this bearish reversal pa...

Stocks are not done yet - Update

There are a few times in history when a third party said this US paper (stocks, funds or bonds) is worthless.

Here is two.

1) 1965 Nixon Shock - The French said to US we do not want your paper dollars please pay us in gold. This of course led to the US going off the gold standard.

2) 2007 Bear Stern Fund Collapse - Investors said their funds collateral was worth much less than stated. This of course was the beginning of the great america housing bust of 2008.


In both cases it was stated .."look the Emperor is naked!"... (The Empe...

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
