I read a lot of stuff, mostly financial, and I'm always interested in others' views. However, I read everything with a critical mindset, especially when there's a paid service being touted. Nevertheless, sometimes 'free' content can highlight some interesting facts about the 'expert' analysis.
I just read this post and noticed something that I decided to share, merely because it is so obvious, it made me smile.
There's a chart within the post which shows the KBW Bank Index plotted against the gold price over the last couple of years. The writer makes the point that the two have been negatively correlated for a long while, and has placed some arrows on the two charts to illustrate this point, with green up arrows on the bank index, and red down arrows on the gold chart. Very easy to follow for the simple souls that might be seeking 'expert' views. (Disclaimer: I am colour blind, but the arrows do look red/green to me).
Trouble is, the arrows don't align at all! Ok, well to be fair, one pair of arrows does align, but two pairs don't align at all, in fact they show that the two charts are positively correlated on those two occasions. Weird eh? Here's the chart with my vertical lines added:
What's most interesting about this little slip up is that the writer often criticises sloppy analysis elsewhere, but isn't immune to it himself. No one is perfect of course (perhaps his ruler slipped), but some are more sanctimonious than others.
