Strategy Risk vs Asset Risk

Alternative Title: How to Avoid Bad Manager Timing

Strategy Risk: If you own a black-box ‘go-anywhere’ hedge fund that invests long and short, uses futures and derivatives at any frequencies, you are mostly exposed to the strategy risk.

The Common Failure of Asset Allocation

Most investors agree that the biggest decision in investing is asset allocation, but few agree on what the best asset allocation strategy is: from “Stocks for the Long-Run” and “Random Walk Down Wall Street”, to “Endowment Style” and “Risk Parity” to “Factor-Based Investing” and “Dynamic Asset Allocation”.
