Charts: Should Investors Favor Small- or Large-Cap Stocks?
And how should market-watchers read the strong divergence between stock indices?
Let's update that analysis in light of the strong divergence between indices such as the large-capitalization S&P 100 (INDEXSP:SP100) and the small-capitalization S&P 600 (INDEXSP:SP600). The analysis would not be materially different if I used the Russell 1000 (INDEXRUSSELL:RUI) and Russell 2000 (INDEXRUSSELL:RUT) indices, accessible via ETFs such as the iShares Russell 1000 Index (NYSEARCA:IWB) and iShares Russell 2000 Index (NYSEARCA:IWM). As I write, the S&P 100 and S&P BSE Small-Cap Index (INDEXBOM:BSE-SMLCAP) have returned 1.65% and -4.36% year-to-date, respectively.
As before, let's note some important distinctions between large- and small-capitalization issues. First, the large-capitalization issues have a significant advantage created by capitalization-weighted index funds such as the SPDR S&P 500 ETF Trust (NYSEARCA:SPY). Second, small-capitalization issues generally have higher price/earnings ratios, lower dividend yields, and greater realized volatility. Investors have to pay more for these stocks, receive less back in the form of dividends, and have to tolerate greater price swings.
Finally, you can explain the business model of an ExxonMobil (NYSE:XOM) or a Merck (NYSE:MRK) while holding a lit match; doing this while explaining assorted cloud-based schemes to sell genetic-based pharmaceuticals on a social network yet to make a dime would result in someone's burned fingers: yours.
Relative Performance Maps
The two charts below depict the three-month total return differential between the OEX and the SML as a function of three-month total returns on the iShares S&P 1500 Index Fund ETF (NYSEARCA:ITOT) and either 7-10 year Treasuries or the Bloomberg correlation-weighted dollar index. OEX outperformance is depicted with green bubbles, SML outperformance is depicted with red bubbles; the diameter of the bubbles corresponds to the absolute magnitude of the performance differential. The last datum used is highlighted in turquoise.
The first chart below confirms the relationship between OEX outperformance and long-term interest rates. As the stock market shifts into a bearish phase and long-term interest rates decline, investors flee into the perceived safety of larger-capitalization issues.

The next chart replaces 7-10 year Treasury returns with changes in the dollar. As the market shifts into a bearish phase and the dollar strengthens, large-capitalization issues outperform.

Where does this leave us at present? In both cases, either a general downturn in the broad market or a continuation of the 2014 trading range will maintain OEX outperformance. A continuation of the 7-10 year rally in Treasuries will favor OEX outpeformance as well, and as this rally seems to be associated with the current trading range in equities, that's sort of a twofer assessment. The dollar is far more problematic as it has been stuck in a three-year trading range and shows no strong predilection in either direction. A stronger greenback favors OEX outperformance and vice versa.
So long as stocks remain in a defensively oriented trading range, the OEX will outperform the SML.
