On Estimating An Asset\'s Implicit Beta
Siegel (1995) has developed a technique with which the systematic risk of a security (beta) can be estimated without recourse to historical capital market data. Instead, beta is estimated implicitly from the current market prices of exchange options that enable the exchange of a security against shares on the market index. Because this type of exchange options is not currently traded on the capital markets, Siegel\'s technique cannot yet be used in practice. This article will show that beta can also be estimated implicitly from the current market prices of plain vanilla options, based on the Capital Asset Pricing Model. We provide empirical evidence on implicit betas using prices of exchange options from the EUREX over years 2000 to 2004.

Replicating Hedge Fund Returns Using Futures - A European Perspective
Hedge funds tend to put a lot of effort into generating their returns and charge substantial fees to do so. However, with the latest performance evaluation studies indicating that hedge fund performance is not truly superior (anymore), the question arises whether it is possible to generate similar, hedge fund-like, returns in a more mechanical way and with less effort. In other words, is it possible to design dynamic trading strategies, mechanically trading stocks, bonds, etc., that generate hedge fund-like returns? If such strategies indeed exist, then this would solve a respectable number of problems surrounding hedge fund investments and alternative investments in general, including the need for extensive due diligence, liquidity, capacity, transparency, style drift and regulatory problems, as well as excessive management fees. In this paper we develop and demonstrate the workings of a technique that allows the derivation of dynamic futures trading strategies, which generate returns with statistical properties similar to hedge funds. Trading nothing else than Eurex DAX 30 and Euro Bund futures, we show that this technique is not only capable of replicating fund of funds returns, but is equally capable of replicating individual hedge fund returns. Accurately replicating the risk-return profile, but sharing none of the drawbacks of real hedge funds, our synthetic hedge fund returns are a worthwhile alternative to direct hedge fund investment.
