The fund has acted as a broad economic gauge. XLI’s top 10 largest holdings include many market leaders, such as Boeing Co. 8.3%, Caterpillar Inc. 3.8% and General Motors Co. 5.0%. The industrial ETF includes a large 27.9% tilt toward the aerospace and defense sub-sector, along with 16.4% industrial conglomerates, 15.% machinery, 10.5% road and rail, 7.4% air freight and logistics, 5.25 electrical equipment, 4.8% airlines, 3.1% commercial services and supplies, and 3.1% professional services.
“If history is any guide, and the XLI breaks below its May lows anytime soon, it won’t be long before the S&P follows,” Maley warned. “Everyone talks about what’s going on in the tech stocks, but we’ve also seen if you look at the industrial names, they’ve played a bigger role in the leadership in the market that most people realize.”
Traders could also hedge against further risk in the industrials sector through bearish ETF plays like the ProShares UltraShort Industrials (NYSEArca: SIJ), which tracks the inverse 2x or -200% daily performance of the Dow Jones U.S. Industrials Index. SIJ jumped 6.6% over the past week as XLI dipped 3.9%.
