ETF Pairs as Sentiment Gauges: IWM and SPY


Recent posts have looked at EEM vs. SPY and XLY vs. XLP as sentiment gauges for the broad stock market. Above we see yet another ETF pair, IWM vs. SPY, as a gauge of speculative sentiment among traders and investors.

The underlying logic is much the same as EEM vs. SPY: traders will be drawn to the smaller, more entrepreneurial, growth-oriented companies when they anticipate economic expansion and will gravitate toward the larger, safer issues when they expect economic weakness.

As we can see above, the small and midcap stocks that are part of IWM have been outperforming the large cap SPY issues, recently moving to relative strength highs. That strength can also be seen in the advance/decline line specific to NYSE common stocks: the broad list of smaller cap issues has been moving the line to bull highs lately.

It is interesting to juxtapose the bullish speculative sentiment of IWM vs. SPY with the more tempered outlook given by EEM vs. SPY. Within the universe of U.S. stocks, we see risk-taking sentiment among traders; that same sentiment is not extending itself globally. Indeed, if we look at large cap stocks across Europe, the Far East, and Australasia (EFA), we can see that those overseas bourses as a whole have not sustained bull highs thus far in 2010.

As long as there is broad participation in upward movement in the U.S., I don't expect any major market correction. Should we begin to see small caps underperform their larger cap counterparts and overseas markets--especially in emerging economies--underperforming the U.S., I would become far more defensive.

Looking at the spread between two etfs or indices is a good tool for a snapshot of what has transpired in the markets, but it is a bit simplistic and, in fact, downright dangerous to extrapolate trends forward based on this lagging indicator.

To really get a grasp of what traders are thinking "now", one must delve deeper and look comparatively at the technical correlations and divergences among the various asset classes, not just the direction of the price spread.

We have just had a decent correction and we may not have seen the end of it. However this just offers the opportunity to take advantage of your etf list of securities and exploit the markets current position.
