The CBOE S&P 500 PutWrite Index has outperformed the CBOE S&P 500 BuyWrite Index by approximately 1.1 percent per year between 1986 and 2015. That is pretty impressive. But troubling. Yes – troubling – because the theory of put-call parity tells us that such outperformance should be almost...

Equity index collar strategies are often perceived as a way for investors, at little to no cost, to exchange some upside exposure for reduced losses on the downside. That perception may be accurate if one considers only the net dollar cost of the strategy's initial option trades, but it fails to...

Recent equity volatility is near all-time lows. Option prices are also low. Many analysts suggest this represents a good opportunity to purchase put options for portfolio insurance.It is well-known that portfolio insurance is expensive on average, but what about in calm markets? History suggests...

This paper explores historical return and risk properties of equity-hedged options across the S&P 500 option surface. We evaluate returns by estimating alpha to the S&P 500 index, and we quantify risk using three metrics: return volatility, losses under stress tests, and conditional value at...

Typical covered call strategies may be decomposed, using a risk and performance attribution methodology, into three components: equity exposure, short volatility exposure, and equity timing. This paper applies that attribution methodology to covered calls on eleven global indexes. We find that,...

Speculators who wish to bet on higher future volatility often purchase options to “go long volatility.” Should investors who buy options expect to profit when realized volatility increases? If so, under what conditions? To answer these questions, we conduct an analysis of the relationship...

This paper explains the risk and returns of US corporate bond indices using a set of economically-motivated factors. In particular, I find that options markets explain a great deal of credit returns. Two particular features of corporate bonds generate option exposure. The first is that, in...

Equity index covered calls have historically provided attractive risk-adjusted returns largely because they collect equity and volatility risk premia from their long equity and short volatility exposures. However, they also embed exposure to an uncompensated risk, a naïve equity market reversal...

A covered call is a long position in a security and a short position in a call option on that security. Equity index covered calls are an attractive strategy to many investors because they have realized returns not much lower than those of the equity market but with much lower volatility....
