For a couple of years now (since the end of 2008), it seems and feels like there is no edge anywhere. Seems to have become a lot more random. Computer driven models, quants, algorithmic systems, high frequency etc are now apparently 80% of all the volume. Things don't correlate anymore on a shorter term basis and of the many many people I know in this business, it seems very few are able to do anything well. Has it become John Connnor vs. the Terminators? Is this every going to change again? Very strange days indeed....open for discussion.
