Large-Cap Stocks Vs. Everything Else

 | Nov 29, 2017 11:57AM ET

I’ve said it numerous times in the last few months, 2017 has been the year of setting records. No one said that trading or investing was supposed to be easy. Albeit some have had the false belief that it is draped around them like a warm blanket during the low volatility year we’ve had. Bitcoins have shot up hundreds of percent, U.S. stocks have refused to put in a material decline and we continue to dance as long as the music keeps playing.

One chart that’s continued to draw my attention is the strength of large cap stocks versus…. well, just about anything else.

This isn’t the first year by any means that we’ve seen focused strength within the market. Just a few years ago in 2013 if you tried to diversify away from U.S. large- or small-cap stocks you were penalized. Large-cap growth was up 33.5% and small caps rose nearly 40%. Even though other markets had a good year, if you went international you underperformed w/ EAFE gaining just 22%, a “diversified” portfolio rose 20% and heaven forbid you owned bonds, which lost 2% that year. (figures from BlackRock). So a year of large-cap strength isn’t anything new and shouldn’t cause too much surprise. But it has because we’ve seen a break from what a commonly healthy market believes about relative performance and risk taking

Turning our attention back to this year and more specifically the last two months. The S&P 500, a cap-weighted index of U.S. stocks has continued to hit new highs as the index most recently moved through 2,600. Meanwhile, many of the other indices that often show positive notes of risk taking have been unable to keep up.

When large caps do well typically the smaller, higher beta/riskier stocks do even better, which we would see in the equal-weighted S&P 500 (RSP) outperforming the cap-weighted SPX. That hasn’t been the case for the bulk of 2017.

What about high-yield bonds? If stocks are doing well then junk bonds should be outperforming aggregate bonds, right? Not for the last two months.

How about high-beta stocks? When U.S. stocks are hitting fresh highs and investors are ratcheting up risk then high-beta stocks should see strength relative to the index…. not for the last two months, no.

Well if large-cap stocks are trending higher then small caps surely are doing even better, because everyone knows that small caps outperform large caps in strong up trends, don’t they? Historically yes, but not for the last two months.
