MIT will run an experiment to see if social media investing improves performance. It’s doing so by giving $100 each to 10,000 Asians to trade forex on eToro by following high-performing traders and copying their trades.
Over at Abnormal Returns is an interview that Tadas Viskanta had with Dr. Wesley Gray of Turnkey Analyst about his book, Quantitative Value. It makes a great case for systematic investing (i.e. investing based on rules, not intuition) and why removing emotion from the investing process is really the best way to success in the investment world. However, he goes a step farther by differentiating between investing based on logic and based on empirical data. The argument focuses on value investing, but I think the case presented is applicable to all styles of investment.
Jay Kaeppel at Optionetics.com has a semi-humorous post about a new algorithmic trading system that he invented today (appropriately called JK Today). On the surface, at least, it appears to be a viable system with good profit potential. In short, he uses the 4% Zweig swing as a directional indicator, and semiconductor to inverse Nasdaq-100 ratio as an overbought/oversold indicator. Again, see the post for the details and his calculations. However, the real point of his post is to show some of the thought process involved in developing a set of rules for a trading system, and what is required of the trader to ensure that the trading system is a success. Here are the performance stats, just to entice you to read it all.
