Top And Bottom Performing Stocks For Week #42

It is Sunday afternoon and that means we get to review the performance of last week’s historical top and bottom stock symbols in the S&P 500. As you may recall these symbols are the result of parsing a database containing over 50 years worth of statistical performance data. The idea is to extract the prospective top ten winners and losers of the coming week purely based on historical statistics.

Systematic Trading Continued. Unwrapping the onion

One continual theme in my own trading is that every time I think I have it figured out – I get punched in the face with a unexpected problem. The tendency is to go more complicated, but often the solution is a degree of acceptance around the nature of the game. Sometimes my edges work, sometimes they don’t. Sometimes they stop working for long periods, 6 months or more. That’s actually ok for me, but it’s not ok for other people. The ultimate systems you choose have to suit your personality. If you cannot handle extended periods of working hard without making money (I can) then you have to retool your systems to avoid this.
