Price and Seasonal Weakness Plague Mid Cap Equities

Last week I discussed the growing divergence within the S&P 500 as the largest components of the index were outperforming the smaller $SPX stocks. To continue on that topic, below we’re going to look at the S&P 400 Mid Cap Index.

$MID recent made a run back to its prior 2017 high but was unable to breakout, creating a lower high in momentum, based on the Relative Strength Index. This creates the third major lower high since its December as momentum continues to weaken for this mid cap index.

While the 100-day Moving Average was able to provide some support during the low earlier in the year, price has unable to gain transaction along with the large cap U.S. equities. The bottom panel of the chart shows the relative performance of the S&P 400 vs. the S&P 500. With relative performance having peaked in December, the ratio line has been putting in a series of lower highs as mid caps struggle to keep up. While price is still well off its prior low, relative performance is beginning to creep closer to its 2017 low, a bad sign for mid cap stocks.

Looking at volume on this daily chart, we can see a recent increase in large selling days. In early April we saw three consecutive above-average days of selling as a short-term low was put in for $MID. However, more recently two more days of above-average down volume have taken place – a sign that many traders attribute to institutional selling.

Turning our focus to seasonality, this recent weakness in the mid cap index begins to make a little more season. Based on the below chart from EquityClock, over the last 20 years, the S&P 400 has put in a short-term high in early May before picking back up later in the month

Going forward I’ll be watching to see how $MID acts if price gets back to the prior ’17 low and if the relative performance ratio does in fact set a new low. This period of weakness does align with long-term seasonality and if the seasonal pattern continues to play out we could see mid caps weaken further until later this month.
