The Basic Materials sector plummeted from my top U.S. Sectors ranks this week, so I decided to take a closer look at each model component. My U.S. sector model is heavily weighted towards momentum indicators, but I have built in several other indicators that act as a counterbalance.
Basic Materials have been a top performer over the past 90, 180, and 250 days. By those measures, this sector is a text book candidate to outperform other sectors over the next few months. However, the Basic Material sector also has several technical negatives to contend with.
First, this sector is overbought. Note the pink bands on both the short term and intermediate term TRIX in the chart above. Even in a bull market, overbought conditions usually signal a pause in upward ascent. What I can't show here is a chart from Jason Goefert of
Sentimentrader.com (It's a subscription service). The Rydex Basic Materials sector fund assets represents 18.3% of all sector funds. That's pure irrational exuberance. Also, the charts on the Proshares Ultra Basic Materials and Ultra Short Basic Materials Assets illustrate sentiment extremes that don't exactly give a contrarian a warm and fuzzy for further gains.
Extreme optimism is only one reason to raise an eyebrow about Basic Materials. I've studied technical analysis for many years, and one of the few reliable indicators that signal market tops is a long term momentum divergence. In the chart above you can see the 60-130-45 Moving Average Convergence Divergence peaked last July. You can also see $DJUSBM continued to climb to ever higher heights. This is a technician's textbook example of a negative divergence - not exactly a bullish sign.
The last bearish tea leaf is seasonality. Historically, May is the beginning of poor performance for the Basic Materials sector. Given that many economist believe the U.S. is in or near a recession, basic materials doesn't seem to be a great place to be for the next few months.
I'd love to hear your thoughts.
