One of the biggest misconceptions about ETFs is that they are highly diversified “baskets” of stocks. Sometimes they are. But as the iShares US Pharmaceuticals ETF (IHE) indicates, even with 60 stock holdings and $1 billion in assets, large ETFs can still be more of a duopoly than a democracy.
With 44% allocated to just two stocks, and 60% allocated across the top six names, the rest are essentially along for the ride. With that important note established, let’s look at the potential up-move IHE is hinting at.

We have to separate whether the strong-looking chart pattern reflects the pair at the top, or a more wholesale rally brewing in pharma stocks.
The chart looks to be on the verge of breaking to new highs, in a way that could lead to a new price trading range. However, this market, now flooded with technicians, is going to test that first. After all, this industry does not get the same “hall pass” that big tech does.
But if you are planning to buy IHE to capture a broad rising tide across the pharmaceutical industry, you need to freeze. Look under the hood of this vehicle, because IHE features an extreme structural configuration that makes it wildly different from other major drug ETFs. This is not an industry-wide breakout — it is an absolute illusion of sector strength masked by a tiny, hyper-concentrated handful of stocks.
The biggest driver is Eli Lilly (LLY). How much has this stock led the industry since last fall? When I pulled up this chart, I still had my old trend channel drawn. When it busted up through $850 it ran to $1,100 faster than you can spell “Glucagon-Like Peptide.” That’s the full name of GLP-1 drugs, the ones that took LLY from “one of the gang” to “leader of the pack.”
Then there’s formerly stodgy Dow Industrials ($DOWI) component stock Johnson & Johnson (JNJ), which has cooled off substantially. And frankly looks lower to me. I’ll spare you all 10 of the top stock charts, and simply say that collectively, they are a mixed bag. That tempers my enthusiasm for IHE.
Because IHE screens for U.S. drug manufacturers and weights them by absolute market value, it has created a highly skewed profile. This structural difference completely answers the question of what is driving this breakout.
