Flash Boys -- halfway there

Well one thing for sure, Lewis knows is "shit".  This book is even better than I thought, no wonder Wall Street is pissed off,via their surrogate: FOX news.  The hubbub has now died down, but I've got to tell you that all the stuff in that book is a roadmap for regulators who want to take action.

My favourite part so far is the 2010 Flash crash explanation.  It merges very well with my own issue with HFT which is the price discovery mechanism (lots of small order that test the market prices -- and disappear quickly -- microseconds).  The SEC report was complete BS because they could not get the data on what happened because they were limited to seconds of trade -- the HFT were working in 1,000 of a second -- the SEC didn't see the trading pattern.

I remember very well that day, I was on the options desk and nobody understood what had happened, first the "fat figure" reason was given (but it turned out there was no such massive trade anywhere in the market.  There was a general shock in the room (and trust me our dealing room was top notch).  Again, were were affected in the periphery (being in Canada where the rules are different than in the US).  We all knew something was wrong (it happened many times afterwards) but we didn't know what was wrong and why the market was doing that (like the characters in ML's book) they had the need and the tools to find out some of the reason for the flash crash.

Today, the market is all math, the genius (trust me they are smart) who created HFTs understand math, understand the underlying market and how it actually operates (as opposed to how we think it works).  The book is even better than I thought.  Although it must be a slog for those who don't understand finance -- and the intricacy of pricing discovery.

Aside from that, spring is finally here for good!

Trucker shortage? No a plan to allow driverless rigs

There are still articles on how America is running out of truckers -- and that its a huge problem, except its not a problem, if it was a problem salaries would rise to so that demand would clear. Trucking is one of those industry where the vast majority of participants are owner/operators and therefore free agents.

Salaries and cost are extremely well know, "industry" complains that there are not enough truckers, yet wages continue to fall... Therefore there are still too many truckers around, for if there was a shortage of supply prices would rise, and they don't.

What there is though is something different; there is a push to allow automatic rigs to "operate across the US", so to encourage the various authorities to allow self driving rigs you talk shortage and hope that politicians decided that "Well if people don't want to work, lets get robots to do the work" or words to that effect.

This has nothing to do with shortage of drivers, but every…

Every punter says oil prices are on the rise: Oil hits $48/bbl -- lowest since September 2016

What the hell?

How could this be, punters, advisors, investment bankers all agreed commodity prices  in general and oil prices in particular are on the rise...its a brave new era for producers and exporters -- finally the world is back and demand is going through the roof, except not so much!

What happened?  Well energy is complicated, the world operates in a balance -- 30 days of physical reserves is about all we've got (seriously) this is a just in time business.  So the long term trend always gets hit by short term variations.

Global production over the past 12 months has risen by somewhat less than 1.5% per annum.  As the world market changes production becomes less energy intensive (maybe), but the reality is that the world is growing more slowly -- America Q4 GDP growth was around 1.9% (annualized) Europe is going nowhere fast (the GDP growth in Germany is overshadowed by the lack of growth in France, Italy, Spain (lets say 27 Euro members generated a total GDP growth of 1.2…

Paying for research

This morning I was reading that CLSA -- since 2013 proudly owned by CITIC -- was shutting down its American equity research department -- 90 people will be affected!

Now the value of a lot of research is limited, that is not to say that all research is bad. In fact, I remember that GS's Asia Aerospace research was considered the bible for the sector.  Granted, there was little you could do with the research since the "buy" was for Chinese airlines...that were state owned.  Still it was a vey valuable tool in understanding the local dynamics.  It seems that the US has introduced new legislation that forces brokers to "sell" their research services!  Figures of $10,000 an hour have been mentioned...

Now, research can be sold many times; if GS has 5000/6000 clients they may sell the same research 300x or 400x (I exaggerate) but this is the key -- Those who buy the research are, I presume, prohibited from giving it away or selling it, at the same time the same rese…
