Using risk-adjusted returns, actual wins versus expected wins, and two holding periods, the results establish that only the XXV consistently produces higher risk-adjusted returns than the S&amp;P 500 regardless of the testing criteria. The SVXY also stands out as superior but underperforms the S&amp;P 500 when the holding period is lengthened. The XIV is a strong performer relative to the S&amp;P, but weaknesses are noted when the ranking criteria, holding period, or portfolio construction are altered. Finally, the benefits of portfolio diversification are found to be insufficient to outperform the S&amp;P 500 for 10 of the 11 constructed portfolios. The pattern of the funds’ returns is such that it causes a reduction in, or even a reversal of, the benefits of portfolio diversification, regardless of the timeframe or ranking criteria applied.TOPICS: Volatility measures, exchange-traded funds and applications, passive strategies
