Just some US charts that interest me. NYSE Cumulative New Highs – New Lows NASDAQ Cumulative New Highs – New Lows
Whilst heading to the gym this morning I heard on the radio that police had seized 280 kilogram of methamphetamine with a street value of $205 million. Apart from thinking I was in the wrong business I thought bullshit. The reason I said bullshit was simply the result of a quick bit of mental arithmetic,…
Apparently the image below has been doing the rounds as the drivers of US stocks. To which I say…. Simply because it ignores the overriding issue of our perceptual driver. The thing in control of all markets is our own tiny brain and the silly things it does.
From The Economist – Some revisions may be down to cock-up but a closer look hints at conspiracy. Counter-intuitively, most fixes aim to make performance look worse than originally stated. That is probably because two-thirds of funds charge performance fees only if they are at or above their highest valuations. Eager to bring forward the time…
Every now and again I tend to review the relative performance of markets to get a sense of what is happening. I also do it to make certain I have not missed something that is glaringly obvious. Such a task is more of an overview hobby because in the world of relative performance not everything…

I tend to subscribe to very few things, one of the things I do find useful si a monthly report that DJ-UBS produce on their commodity indices The report comes out once a month and has the following format. Looking at a chart is good but your eyes can play tricks on you which is…
This Friday we have Kora Reddy of asxiq dropping by as a guest contributer, who for the next three weeks will be going through some of the intricacies of back testing. Why Backtest a strategy? Quick answers to the question: to determine whether a theory or hypothetical construct is valid in historical testing to summarize…
Thomas Henry Huxley was referred to as Darwins bulldog for his defense of evolution. Dawkins follows admirably in the tradition of defending rationality against the growing number of idiots that increasingly populate the world. .
The folks at Freakonomics Radio have an excellent new podcast. So when is a negative a positive? When the negative is feedback. We focus on a clever research project byAyelet Fishbach of the University of Chicago andStacey Finkelstein at Columbia. It argues that positive feedback certainly has its role — especially when someone isn’t yet fully invested…
