As stock market valuations continue to rise and expected returns correspondingly fall, many investors are hoping to rely more on alpha from active management to make up for a potential future return gap. Unfortunately, long-only active management has struggled during recent history. We review why portable alpha may be an attractive alternative solution in today’s market environment. We also discuss what aspects of a portable alpha solution are important for investors to consider when selecting between implementations.

We validate this "virtue of complexity" result in three practical market timing applications.

February 6, 2024
We analyze the historical macroeconomic sensitivity of traditional asset classes and major hedge fund strategies. We show that the average hedge fund is unlikely to provide meaningful diversification during periods of macro uncertainty, which are also typically difficult for traditional assets. However, long/short low-risk strategies have tended to exhibit low macro sensitivity.
