摘要

全球金融危机的低谷已经过去了十年,美国股市经历了历史上最长的上涨期之一。一些投资者开始质疑美国股市是否被高估,以及经济衰退是否即将到来。通常无法预测下一次金融危机。投资者最好的做法可能是调整投资组合,以抵御潜在的市场逆风。本文主张利用波动性风险溢价(VRP),特别是期权销售VRP策略,来减轻投资组合在未来金融危机中可能遭受的损失。这种VRP策略,如果与资金外股票指数期权一起实施,可以帮助投资者缓冲股市崩盘造成的损失,并比整个股市更快地复苏。投资者可以单独使用VRP,也可以将其与传统股权相结合,构建最合适的投资策略。本文进一步考察了这些战略的实施选择,并通过过去三十年中四次具有代表性的危机对其表现进行了压力测试。主题:对个别因素/风险溢价、财富管理、金融危机和金融市场历史的分析关键发现•美国股市在经历了十年的反弹后可能被高估,投资者的最佳方法可能是针对潜在的市场逆风调整投资组合。•波动性风险溢价(VRP),特别是期权销售VRP策略,可以帮助投资者减轻投资组合在未来金融危机中可能遭受的损失。•有两种机制有助于覆盖VRP策略:低德尔塔期权只有在指数低于执行价格后才开始支付;更高的隐含波动率(IV)转化为危机时期更高的保费收取。

Using the Volatility Risk Premium to Mitigate the Next Financial Crisis
Ten years have passed since the trough of the Global Financial Crisis, and the US equity market has experienced one of the longest stretches of ascent in history. Some investors have started questioning whether the US stock market is overvalued and if a recession is on the way. It is usually impossible to predict the next financial crisis. An investor’s best course of action may be to adjust the investment portfolio to be resilient against potential market headwinds. This article argues for utilizing the volatility risk premium (VRP), specifically option-selling VRP strategies, to mitigate the losses the portfolio may suffer from a future financial crisis. Such a VRP strategy, if implemented with out-of-the-money equity index options, can help investors cushion the losses from an equity market crash and recover more quickly than the broad equity market. Investors can utilize the VRP by itself or combine it with traditional equity to construct the most suitable investment strategies. This article further examines implementation choices of such strategies and stress tests their performance with four representative crises from the past three decades. TOPICS: Analysis of individual factors/risk premia, wealth management, financial crises and financial market history Key Findings • The US equity market may be overvalued after the decade-old rally, and an investor’s best approach may be portfolio adjustment against potential market headwinds. • The volatility risk premium (VRP), specifically option-selling VRP strategies, can help investors mitigate losses the portfolio may suffer from a future financial crisis. • Two mechanisms help overlay VRP strategies: low delta options only initiate payouts after the index fall below strike prices; higher implied volatility (IV) translates into higher premium collection in crisis times.
