In this article, the authors review the diversification and other performance characteristics of cat bonds and study their value in the context of portfolio allocation. They find that cat bonds{\textquoteright} low correlation to equities, fixed income, and hedge fund indexes can make them compelling from a diversification standpoint. Moreover, cat bond performance over the past 14 years has been a steady 8.3\% annual average return with volatility of 2.8\%, for a realized Sharpe ratio of 2.4. However, this performance has in part been the result of lower-than-expected principal writedowns during this period. Furthermore, cat bonds may have become a victim of their own success, as a combination of investor appetite and limited supply has pushed their yields to unprecedented low levels{\textemdash}2.5\% as of this writing, which equates to an expected Sharpe ratio of 0.5. Though still compelling from a diversification standpoint, these yields might not justify their relative illiquidity and the risk of investing in a relatively unknown security.TOPICS: Fixed income and structured finance, global, portfolio construction, performance measurement}, issn = {1520-3255}, URL = {https://jai.pm-research.com/content/19/1/27}, eprint = {https://jai.pm-research.com/content/19/1/27.full.pdf}, journal = {The Journal of Alternative Investments} }
