I wrote last week that there was a stream of new products being launched, all designed to increase the attraction of FX as an asset class. In my haste to meet my deadline, I forgot to mention that Credit Suisse had launched what it calls its rolling optimized carry indices (ROCI), though I know it may seem inconceivable that I could do so, given the products’ snappy name. This week, with my tail slightly between my legs, I will make amends. Credit Suisse says the ROCI offer investors an efficient and transparent method to participate in FX carry trading. Backward testing shows that the US dollar-based ROCI optimised forward bias strategy has returned 17.1% per annum with an annual realised volatility of 7.8% over the past eight years. In comparison, the S&P 500 has returned a paltry 3.1% per annum with an annual volatility of 17.7% over the same period.
