Small caps are underperforming and, if history is any indication, it could be a warning sign for the broader market.
Unlike the Dow, S&P, and Nasdaq, all of which soared to all-time highs on Wednesday after Fed Chairman Jerome Powell signaled a rate cut may be coming this month, the Russell 2000 hasn't hit a new high since last August. It's currently trading about 10% below its peak.
Miller Tabak's Matt Maley argues that investors should take note of the Russell's slowdown since in multiple instances over the past four decades it's been a precursor for problems in the broader market.
"I'm very concerned about those who say that the small caps don't matter too much... There's been so many other times where it's been a very big warning signal," he said Wednesday on CNBC's "Trading Nation."
After looking at the index's chart, Maley says that the Russell has been trading in a trend channel since the beginning of the year, and that if it breaks below its low from January 3, it would be a "big, big warning sign for the rest of the market."
He also warned that the current economic backdrop of slowing growth and domestic earnings estimates coming down are additional headwinds that small-cap companies must face.
Maley was quick to note that he's not predicting "a crash or anything like that," but that investors' ignoring the small-cap slowdown do so at "their own peril."
Chad Morganlander of Washington Crossing Advisors said he remains "underweight small caps at this point" since he anticipates they will continue to underperform over the next 12 months.
"The reality is we're having a global slowdown and small-cap indices, they're cyclically exposed. Largest component is financials, industrials, and materials. So we would be avoiding small caps all together...because of the flattening of the yield curve, trade concerns, and global growth."
Instead, he recommends being "overweight large-cap quality companies," particularly in the "health-care and consumer staples" sectors.
