Weekend Linkfest!

The Beta in Alpha's clothing? (pdf) Bridgewater Associates' detail how various hedge fund's are charging Alpha prices for Beta returns.

How to differentiate Alpha from Beta in those hedge funds? Check out AllAboutAlpha's post titled, Mommy, Where do alphas come from? AllAboutAlpha does a great job of summarizing Andrew Lo's paper, Where Do Alphas Come from?: A New Measure of the Value of Active Investment Management. Lo explains how to differentiate active returns from passive and more importantly what value the active returns add to the total returns of the portfolio. Cool stuff!

Very interesting draft, When Do Stop-Loss Rules Stop Losses?, by Kathryn M. Kaminski and Andrew W. Lo. They find stop-losses improve returns and reduce volatility compared to buy & hold. And stop-out periods were distributed uniformly over time versus only during small market crashes.

MOSERS discusses how to handle residual cash in a portfolio in the following newsletters, Rebalancing and Cash Securitization and Rebalancing II. I was shocked to discover how big of an impact residual cash had on my returns during my market studies. A cash drag indeed! Very important to get that cash, no matter how small, back into the market in order to generate further market returns.

Enjoy your week!
