(New York)

One of the ways that investors or advisors might think to diversify their risk is to invest in a number of different managers. The reality is, however, that many of those managers, especially within an asset class, will all have similar looking portfolios, which means you may be much less diversified than you think. The obvious analogue is index tracking funds. There would be no point in buying multiple ETFs from different providers that all track the same index. Yet that is what investors are doing in some markets. This concept is particularly relevant for the riskier end of the credit markets right now, where the market seems to be poised for the same kind of correlated fall as happened during the Crisis. In CLOs for instance, many of the largest loans are held by a majority of the major managers.

FINSUM: This seems like a smart and timely warning. Correlation can doom even the best diversification efforts, especially when it is credit driven.
