Stock Market Decline is Broad

We typically expect to see small company stocks decline first and decline the most. The theory is that smaller companies, especially micro companies, are more risky so their value may disappear faster.  Below, we view the recent price trends of four market capitalization indexes: micro, small, mid, and mega. We’ll use the following index ETFs.

Vanguard ETFs small mid large micro cap

Since we are focused on the downside move, we’ll only observe the % off high chart. This shows what percentage the index ETF had declined off its recent highest price (the drawdown). We’ll also observe different look-back periods.

We first look back 3 months, which captures the full extent of the biggest loser: as expected, the micro cap index. The iShares Micro-Cap ETF (IWC: Green Line) seeks to track the investment results of an index composed of micro-capitalization U.S. equities. Over the past 3 months (or anytime frame we look) it is -13% below its prior high. The second largest decline is indeed the small cap index. The Vanguard Small-Cap ETF (VB: Orange Line) seeks to track the performance of the CRSP US Small Cap Index, which measures the investment return of small-capitalization stocks. The small cap index has declined -11.5%. The Vanguard Mega Cap ETF (MGC) seeks to track the performance of a benchmark index that measures the investment return of the largest-capitalization stocks in the United States and has declined -9.65%. The Vanguard Mid-Cap ETF (VO) seeks to track the performance of a benchmark index that measures the investment return of mid-capitalization stocks and has declined -9.41%. So, the smaller stocks have declined a little more than larger stocks.

Many active or tactical strategies may shift from smaller to large company stocks, hoping they don’t fall as much. For example, in a declining market relative strength strategies would rotate from those that declined the most to those that didn’t. The trouble with that is they may still end up losing capital and may end up positioned in the laggards long after a low is reached. They do that even though we may often observe the smallest company stocks rebound the most off a low. Such a strategy is focused on “relative returns” rather than “absolute returns“. An absolute return strategy will instead exit falling trends early in the decline with the intention of avoiding more loss. We call that “trend following” which has the objective of “cutting your losses short”. Some trend followers may allow more losses than others. You can probably see how there is a big difference between relative strength (focusing on relative trends and relative returns)  and trend following (focusing on actual price trends and absolute returns).

So, what if we look at the these stock market indexes over just the past month instead of the three months above? The losses are the same and they are very correlated. So much for diversification. Diversification across many different stocks, even difference sizes, doesn’t seem to help in declining markets on a short-term basis. These indexes combined represent thousands of stocks; micro, small, medium, and large. All of them declined over -11%, rebounded together, and are trending down together again.

If a portfolio manager is trying to “beat the market” index, he or she may focus on relative strength or even relative value (buy the largest loser) as they are hoping for relative returns compared to an index. But a portfolio manager who is focused on absolute returns may pay more attention to the actual downside loss and therefore focuses on the actual direction of the price trend itself. And, a key part is predefining risk with exits.

You can probably see how different investment managers do different things based on our objectives. We have to decide what we want, and focus on tactics for getting that.

Stock Market Peak? A Tale of Two Markets

One of the early warning signs that a bull market in stocks is nearing its end is increasing selectivity. As more investors begin to believe a peak may be near based on statistical analysis or valuation, they may get positioned more defensively. Eventually we observe some stocks participating in a rising trend as others trend down early. Over the past several weeks we have observed a material divergence between large company stocks like those in the Dow Jones Industrial Average (DIA) vs. small company stocks like those in the Russell 2000 Index (IWM). As you can see below, the Russell 2000 index has declined nearly 9% while the Dow Jones Industrial has gained about 2%. Since the Dow Jones Industrial is more popularly quoted in the media, most investors probably believed “the market was still rising”. But unless you only have positions in the largest company stocks, you’re noticing that isn’t the case in terms of the broad market. Small company stocks tend to lead on the downside, so we shouldn’t be surprised if we see the larger companies follow them down at some point. You can probably see how this basic observation leads to further study of market breadth: looking at what percent of stocks are rising vs. falling.

Is this the “tail” of two markets?

Of course, the direction of the overall market is interesting to monitor, but it only matters what positions we have at risk.
