Complacency in the Options Market? Most of the risk indicators we follow suggest we are living in a period of market complacency. However, we believe equity risk expectations are unreasonably low, particularly in light of a host of possible market-moving catalysts that could increase investor uncertainty.

Options on the VIX. Open interest has increased steadily since VIX options began trading slightly more than a week ago. Although implied volatility data and the information content inferred from the various strike levels and expiration terms in VIX options are likely to become more reliable as liquidity in these contracts increases, we believe the current shape of the curve provides insights into the extent of complacency in the marketplace.

Mean Reversion in Implied Volatility Skews. We find that implied volatility skew displays a tendency to revert to its longer term mean. Higher levels of skew, measured by percentile ranking relative to their 1-year history, tend to be followed by lower skew levels in the future with increasing probability. This is found to be true for put skews as well as call skews.

Equity Volatility Overview Most of the risk indicators we follow suggest we are living in a period of market complacency. First, short-term equity risk expectations remain near multi-year lows. In fact, as Figure 1 illustrates, S&P 500 3-month implied and 66-day realized volatility are again approaching levels not observed since the end of 1996.

Second, longer-term risk expectations (3-month forward volatility in 9 months’ time) are hovering near multi-year lows, and have continued to decline this year, as the S&P 500 rallied since Q4 2005 and is approaching 5-year highs (Figure 2).

In addition, the 3-month S&P 500 skew continues its decline, suggesting investors continue to place incrementally smaller bids for downside protection against market downturns. This measure is closely related to the level of implied volatility itself, and we explore index volatility skew more closely later in this report.

Credit spreads also continue to trade near historically low levels and the high-yield spread relative to the spread on investment grade debt is also near its all-time lows. This might be a signal that investors’ tolerance for risk has increased and expanded across asset classes.

Complacency Unwarranted?

We believe equity risk expectations are unreasonably low, particularly in light of a host of possible market-moving catalysts that could be forthcoming and are likely to spill over into a more volatile equity market.

For example, there still remains uncertainty regarding when the Fed is likely to stop raising rates (Lehman’s forecast is continued hiking until the August or September FOMC meeting, with the Fed Funds rate peaking at 5.5%). If the Fed continues to raise rates, there runs the risk that the consumer will begin to cut back on spending and the housing market could weaken, thereby reducing home equity extraction. Moreover, since the Fed is expected to become more dependent on economic data releases, we expect the market to become more “unsettled” prior to such releases. For instance, the average absolute daily return of the S&P 500 in response to releases of non-farm payrolls decreased over the “measured” rate hike period and was the lowest in 2005 (Figure 3). The market’s reaction has been larger thus far in 2006; if this persists going forward, option market participants could begin to price in larger moves as well, resulting in elevated levels of implied volatility.

In addition, we believe concern over rising energy prices (potential geopolitical risks in key oil-producing nations, active hurricane season, rising demand during summer months, etc.) and this year’s mid-term congressional elections could contribute to higher market anxiety. Event risks such as an avian flu outbreak could also be a catalyst for greater uncertainty.

Volatility Trading Environment

VIX Options

Options on the VIX index have been widely awaited by investors and commenced trading on February 24. In a little more than a week since these options started trading, open interest has increased steadily (Figure 4) and the popularity of VIX options can be expected to rise as a larger proportion of long-only fund managers begin using them as a “catastrophe hedge”.

The implied volatility surface of VIX options exhibits the expected premium for writing out-of-the-money calls (Figure 5). While implied volatility data and the information content inferred from the various strike levels and expiration terms are likely to become more reliable as liquidity in these contracts increases, we believe the current shape of the curve provides insights into the extent of complacency in the marketplace. Thus, one might expect the higher strikes for the April and May maturities to trade at a significant premium to the at-the-money strike, yet the skew is essentially flat at present. Although there are currently not enough data points to draw statistically meaningful conclusions, we believe a persistence of this pattern could indicate unreasonably low levels of “fear” in the market.

Mean Reversion in Implied Volatility Skews

Introduction

According to the Black-Scholes option valuation model, implied volatility is assumed to be constant across all strikes and expirations. However, in practice, option contracts trade with different implied volatilities, depending on their maturity as well as the distance of the strike from the underlying stock price.

The tendency for lower strikes in index options to trade at higher levels of implied volatility has been observed since the stock market crash of 1987. Since then, writers of out-of-the-money puts have tended to demand a premium to compensate for the insurance they provide. In addition, demand/supply technicals explain the sustained existence of a volatility skew in index options. Equity investors, in aggregate, have a net long exposure to equity markets and are a natural source of demand for purchasing out-of-the-money puts, thus raising the implied volatility for lower strikes. On the other hand, they tend to supply volatility at higher strikes by selling out-of-the-money calls as part of systematic overwriting strategies, thus suppressing implied volatility at higher strikes.

Another perspective that helps explain skew in the volatility surface is the return distribution of equities. If the Black-Scholes theoretical assumption of stocks’ lognormal distribution was valid, implied volatility would be expected to be flat across strikes. However, the actual return distribution over an extended period of time indicates that equity returns exhibit negative skewness, with fatter downside tails. This supports the notion that investors bid up protection for options having very low strike prices, resulting in higher implied volatility for contracts at these strikes.

Volatility Skew as a Measure of Market “Fear”

Implied volatility is frequently used as a risk indicator in the equity market since there is a well established negative correlation between spot prices and implied volatility. We find that SPX skew, as measured by the difference in implied volatility for the 20-delta puts and calls, moves closely with the level of implied volatility, and can be considered an alternate metric of market “fear” (Figure 6). We also find that daily changes in implied volatility are strongly correlated with daily changes in skew levels (Figure 7).

However, at the single-stock level, implied volatility changes do not appear to be a strong predictor of changes in skew (Figure 8).

Mean Reversion in Volatility Skew

We have found that the spread of implied relative to realized volatility displays a tendency to revert to its longer term mean1. We now test whether a similar reversion exists for volatility skews. We consider the 20 delta put – 20 delta call skew on 3-month S&P 500 options since 1996. We categorize skew as being “rich” if it is trading at a high percentile relative to where it had traded during the prior year. On the other hand, if it stands at a lower percentile relative to its 1-year history, we label it as “cheap”. If volatility skew indeed exhibits mean reversion, we would expect periods of high skew percentiles to be followed by lower skew in 3 months’ time, and vice versa.

Figure 9 demonstrates that such mean reversion does tend to occur, as successively higher percentiles of skew tend to precede greater declines in skew. For example, on average, when skew was initially labeled as being very “rich” (skew level at a percentile greater than 95%), the skew stood at a lower value in 3 months in 91% of cases and the median drop in skew in these instances was over 2.7%.

On the other hand, when skew was trading at a low percentile relative to its history (“cheap”), its subsequent change tended to be positive, though at a lower degree of magnitude than that of “rich” skew. We believe this reflects the fact that during the sample period of the study, skew on index options has, on average, been in a declining trend. (Thus, the likelihood of “rich” skew being followed by lower skew has been greater than the probability of “cheap” skew being a predictor of elevated skew in future.)

Put Skews vs Call Skews

Having established the mean reverting characteristics of volatility skew, we now examine the components of skew more closely. Specifically, rather than analyzing the total difference in put and call implied volatility, we now analyze mean reversion in the put skew (OTM put implied vol – ATM implied vol) and call skew (ATM implied vol – OTM call implied vol) separately.

As Figure 10 and Figure 11 illustrate, put skews and call skews have displayed a tendency to revert to their medium-term averages. The effect is stronger for “rich” skew than for “cheap” skew, similar to the observation for put-call skews.

Conclusion

Possible strategies for taking advantage of the mean reversion characteristics in skew include buying or selling delta-hedged spreads. For example, an investor who believes the put skew is trading at very low levels and expects it to increase, can sell put spreads by buying out-of-the-money puts and writing at-the-money puts. Although hedging the net delta of the spread can theoretically eliminate this position’s exposure to the changes in the underlying index, we note that the position would have some exposure to time decay (theta), which can be partly mitigated by selecting longer term options. Moreover, the success of any strategy attempting to exploit the change in skew would depend on the bid-ask spreads involved. For illiquid out-of-the-money contracts, total transaction costs could overwhelm the profit from the expected movement in skew.

Appendix I: Sector Volatility Snapshots

In this section, we show our Sector Volatility Snapshots. These snapshots allow investors to quickly assess aggregate volatility information for each GICS sector in the S&P 500 Index.

The average volatility (implied or realized) for a GICS sector is calculated as the weighted- average-volatility of each of their respective index constituents, weighted by market capitalization. The weighted-average volatility for a GICS industry group is obtained similarly. ETFs having options are mapped to one GICS sector each, although the mapping is not perfect since stocks in an ETF could be classified into multiple sectors as per the GICS sector classification methodology. However, they closely reflect the performance and volatility characteristics of the sectors and industries they represent.

• We display the weighted-average implied and realized volatility at the sector level for a one year period. For each industry group within the sector and each ETF that closely resembles the respective industry or sector, we provide the number of standard deviations the current level of the implied-realized volatility spread is trading above or below to its one-year historical mean. A highly negative standard deviation could indicate that options are trading cheap, whereas a highly positive standard deviation possibly implies such options are relatively rich. (Note that there usually do not exist actively traded options at the industry group level and the relative richness/cheapness indicators for these industry groupings should only be used only as a starting point for identifying single-stock volatility trades within that industry group. Furthermore, while options on ETFs exist, their liquidity should be taken into account before executing a trade, since many are currently thinly traded as well.)

• The “Largest Implied Volatility Increases” and “Largest Implied Volatility Decreases” denote the stocks within the sectors that have experienced the highest and lowest absolute changes in implied volatility, over one-week and one-month periods.

• The Put-Call Skew is calculated as the difference between the 3-month put-implied volatility and the 3-month call-implied volatility for 20 delta puts and 20 delta calls, divided by the 3-month at-the-money implied volatility. The weighted-average skew at the sector and industry group level are calculated similarly, except the volatility used is the market-cap weighted-average implied volatility. If the current skew level is trading a relatively high number of standard deviations above its one-year average, this could indicate the option market is pricing in increasing risk expectations for the underlying stock, since the put–call implied volatility differential implies that option traders have been bidding up put protection, rather than upside participation via long call positions.

• We show the history of the slope of the volatility term structure as measured by the difference between 12-month and 3-month at-the-money implied volatilities. Since longer term implied volatility tends to be more stable than implied volatility on shorter-dated options, a lower term structure spread relative to its historical pattern could indicate 3-month options are trading richer than they typically have in the past. Alternatively, if the slope of the term structure is relatively steep, one might infer near term options are trading at a relative discount to longer dated options.

Sector Highlights

Lehman’s U.S. Equity Strategy team has raised its weighting of the Telecommunication Services sector to Overweight from Market-Weight on the back of improved conditions in end markets, realization of consolidation benefits and strong wireless revenue trends.

Implied volatility for the Telecom sector on a market-cap weighted-average basis has lagged realized volatility, and its current 3-month implied-realized spread stands more than one standard deviation below its 1-year average. We observe that the Telecom HOLDRS Trust (TTH) ETF has had increasing interest among investors, with the total number of contracts traded in February increasing more than two-fold relative to that of January. We recommend investors looking to implement a bullish view on the Telecom sector consider purchasing relatively inexpensive calls on TTH (Figure 12) or some of its largest constituents.

3-month implied volatility for the S&P 500 Health Care sector steadily declined through February, and currently trades at a discount to 66-day realized volatility. This has been true for both U.S. Major Pharmaceuticals as well as Health Care Equipment stocks. Lehman Brothers' Pharmaceuticals analyst Anthony Butler and Medical Supplies analyst Bob Hopkins currently have positive ratings on their respective sectors. We believe investors wishing to implement a bullish directional view for the Health Care sector should consider purchasing relatively cheap calls on the Pharmaceutical HOLDRS Trust (PPH) ETF (Figure 13).

Note: The put-call skew is calculated by taking the difference between the 20-Delta put-implied volatility and 20-Delta call-implied volatility, divided by the 3-month ATM implied volatility. Sector level volatilities are the market cap weighted implied volatilty for each constituent. A high skew is generally associated with a relatively high demand for downside protection.

Note: The term structure spread is calculated by taking the difference between the 12-month ATM implied volatility and the 3-month ATM implied volatility. Sector level term spread is calculated from the market cap weighted implied volatilities of the constituents. A steep term structure indicates shorter-dated implied volatility could be cheap relative to longer-dated implied volatility.

Note: We calculate each sector's average implied volatility by weighting the 3-month at-the-money implied volatility of its constituents by market capitalization. Investors should consider liquidity of options of a stock or ETF before entering an options position since, although options on ETFs exist, many are thinly traded.

Note: The put-call skew is calculated by taking the difference between the 20-Delta put-implied volatility and 20-Delta call-implied volatility, divided by the 3-month ATM implied volatility. Sector level volatilities are the market cap weighted implied volatilty for each constituent. A high skew is generally associated with a relatively high demand for downside protection.

Note: The term structure spread is calculated by taking the difference between the 12-month ATM implied volatility and the 3-month ATM implied volatility. Sector level term spread is calculated from the market cap weighted implied volatilities of the constituents. A steep term structure indicates shorter-dated implied volatility could be cheap relative to longer-dated implied volatility.

Note: We calculate each sector's average implied volatility by weighting the 3-month at-the-money implied volatility of its constituents by market capitalization. Investors should consider liquidity of options of a stock or ETF before entering an options position since, although options on ETFs exist, many are thinly traded.

This document is for information purposes only and it should not be regarded as an offer to sell or as a solicitation of an offer to buy the securities or other instruments mentioned in it. No part of this document may be reproduced in any manner without the written permission of Lehman Brothers. With the exception of disclosures relating to Lehman Brothers, this research report is based on current public information that Lehman Brothers considers reliable, but we make no representation that it is accurate or complete, and it should not be relied on as such. In the case of any disclosure to the effect that Lehman Brothers Inc. or its affiliates beneficially own 1% or more of any class of common equity securities of the subject company, the computation of beneficial ownership of securities is based upon the methodology used to compute ownership under Section 13(d) of the United States' Securities Exchange Act of 1934. In the case of any disclosure to the effect that Lehman Brothers Inc. and/or its affiliates hold a short position of at least 1% of the outstanding share capital of a particular company, such disclosure relates solely to the ordinary share capital of the company. Accordingly, while such calculation represents Lehman Brothers’ holdings net of any long position in the ordinary share capital of the company, such calculation excludes any rights or obligations that Lehman Brothers may otherwise have, or which may accrue in the future, with respect to such ordinary share capital. Similarly such calculation does not include any shares held or owned by Lehman Brothers where such shares are held under a wider agreement or arrangement (be it with a client or a counterparty) concerning the shares of such company (e.g. prime broking and/or stock lending activity). Any such disclosure represents the position of Lehman Brothers as of the last business day of the calendar month preceding the date of this report. This material is provided with the understanding that Lehman Brothers is not acting in a fiduciary capacity.

Value and income may be adversely affected by exchange rates, interest rates, or other factors. Past performance is not necessarily indicative of future results. If a product is income producing, part of the capital invested may be used to pay that income. © 2006 Lehman Brothers. All rights reserved. Additional information is available on request.
