The two weeks heading into earnings have tended to be a period of smallcap underperformance; largecap valuations continue to be extremely cheap relative to smallcaps. The IWM-SPX implied vol spread has cheapened to levels last seen in early June. We believe fundamental and seasonal factors make this an opportune time to enter this spread.Lehman Brothers does and seeks to do business with companies covered in its research reports.

Equity Derivatives Strategy | Index Volatility Commentary Smallcap Vols Cheap Smallcap Vols Cheap Relative to Largecap Vols Since the beginning of the year, IWM options have gained in popularity as a punting vehicle. Average listed volume in IWM contracts more than doubled in the month of May in comparison to the previous month. Though volumes have come off in recent months as the demand for downside protection has receded, monthly IWM option volumes remain higher than in early 2006 (Figure 1). An environment where macroeconomic data was deemed more important for determining the path of Fed policy made the Russell 2000 a more attractive instrument for placing leveraged bets. Another explanation for the greater use of IWM options could be the increasing beta of the Russell 2000 relative to the SPX, which is currently at multi year highs (Figure 2). This is largely explained by the extremely serene levels of largecap realized vols (1-month realized volatility for the S&amp;P 500 has been hovering in the 7-8% range).Figure 1: IWMs are the favored punting vehicle in a sell-off Figure 2: RTY beta to SPX at multi year highs 700,000 2.0 600,000 Avg SPX Option Volume RTY Beta vs SPX Avg IWM Option Volume 1.5 (Rolling 3-month) 500,000 400,000 1.0 300,000 200,000 0.5 100,000 0.0 0 5 6 7 8 9 0 1 2 3 4 5 6 06 6 06 06 06 06 06 r-9 -9 r-9 r-9 r-9 r-0 r-0 r-0 r-0 -0 r-0 r-0 06 06 l-0 r r p- - n- n- b- - g- r- Ap Ap Ap Ap Ap Ap Ap Ap Ap Ap Ap Ap ay ar Ju Ja Ju Fe Ap Se Au M MSource: Lehman Brothers, OptionMetrics Source: Lehman Brothers, OptionMetrics, FAME Seasonal effects argue for smallcap underperformance in the short run. The two weeks heading into the start of earnings season have tended to be a period of weakness for the IWM. Out of the 15 such periods since 2003, the IWM has finished lower on 10 occasions. The IWM-SPX implied vol spread for the 1-month maturity has also widened on 9 out of these 15 instances. Lehmans Equity Strategists have highlighted that based on median forward P/E multiples, largecap valuations are historically cheap relative to smallcaps. In keeping with this and the heightened macro risks, smallcap vols kept getting bid up relative to largecap vols till the middle of August. The spread has been reversing for the subsequent two months. Following last weeks outperformance of the Russell 2000, IWM implied vols have cheapened further relative to the SPX. 1-month IWM implied volatility currently trades at an 8 pt premium to SPX options. This is the cheapest the spread has been since early June (Figure 3). October 10, 2006 2 </li> <li> 3.
