DIA vs. IWM: A Matter of Giants and Goblins

by

Right then. We have before us two curious artifacts of the modern financial sorcery: the SPDR Dow Jones Industrial Average ETF Trust (DIA), and the iShares Russell 2000 ETF (IWM). One, a gathering of the established, the…well, the very established. The other, a teeming horde of smaller enterprises, like a particularly ambitious colony of goblins hoping to become merchants. Both, naturally, are attempting to extract wealth from the pockets of investors. The question is, which offers the slightly less…complicated path to doing so?

The DIA, you see, is rather like a carefully curated collection of dragon hoards – thirty of the biggest, shiniest, and most heavily guarded. It represents the Dow Jones Industrial Average, which, despite the name, has very little to do with actual industry and a great deal to do with…prestige. The IWM, on the other hand, is more akin to a goblin market – nearly two thousand smaller companies, bustling and chaotic, and occasionally trying to sell you slightly dodgy enchanted trinkets. This comparison delves into the cost, performance, risk, and composition of these two funds, to help you determine which best suits your particular brand of financial wizardry.

Snapshot (Cost & Size)

Metric IWM DIA
Issuer iShares SPDR
Expense ratio 0.19% 0.16%
1-yr return (as of 2026-01-09) 20.0% 18.1%
Dividend yield 1.0% 1.4%
Beta 1.13 0.91
AUM $77.7 billion $44.6 billion

Beta, you ask?1 It’s a measure of how much a fund bounces around compared to everyone else. A low beta suggests a certain…stoicism in the face of market mayhem. A high beta indicates a tendency to panic and flail about. The 1-yr return is simply what happened in the last year. Past performance, as the wizards always say, is no guarantee of future results. Though, frankly, in this business, it’s often a remarkably accurate predictor of continued…peculiarity.

The DIA, it seems, is slightly less expensive and currently offers a marginally better dividend yield. This may appeal to those seeking a slightly lower cost, and a slightly higher payout. Though, of course, a higher payout doesn’t necessarily mean a better investment. It simply means less gold remaining in the coffers for future…endeavors.

Performance & Risk Comparison

Metric IWM DIA
Max drawdown (5 y) -31.91% -20.76%
Growth of $1,000 over 5 years $1,341 $1,749

What’s Inside

The DIA, as previously mentioned, tracks the Dow Jones Industrial Average, holding a mere thirty blue-chip stocks. It’s a remarkably concentrated portfolio, akin to a very selective guild of master craftsmen. Sector exposure leans heavily towards financial services (28%), technology (20%), and industrials (15%). The largest positions include Goldman Sachs Group Inc (GS), Caterpillar Inc (CAT), and Microsoft Corp (MSFT). With twenty-eight years of history and a focused lineup, the DIA may appeal to those seeking established names and lower volatility. Though, it’s worth remembering that “established” doesn’t necessarily mean “safe”. It simply means they’ve had more time to accumulate…influence.

The IWM, by contrast, holds roughly 1,950 U.S. small-cap stocks, delivering broad diversification across the market’s smaller companies. It’s a chaotic, bustling marketplace, where fortunes are made and lost with alarming regularity. Sector allocation is more balanced, with healthcare (19%), financial services (16%), and technology (16%) as the main weights. Top positions like Bloom Energy Class A Corp (BE), Credo Technology Group Holding Ltd (CRDO), and Kratos Defense And Security Solutions (KTOS) comprise a much smaller slice of assets, reflecting the ETF’s wide reach. It’s a bit like trying to herd cats, but with potentially lucrative results.

What This Means For Investors

The SPDR Dow Jones Industrial Average ETF Trust (DIA) and iShares Russell 2000 ETF (IWM) are two of the most well-known and largest ETFs around. Each fund tracks an iconic stock market index, the Dow Jones Industrial Average and the Russell 2000 index, respectively. So, here’s what retail investors need to know about these two ETFs.

To start, the most significant difference between these two funds is the size and type of their holdings. The DIA holds only 30 stocks, while IWM holds close to 2,000. In addition, the DIA tilts heavily towards large and megacap stocks. Meanwhile, IWM’s extensive portfolio tilts far more towards medium and small caps.

As for the key financial and performance metrics, DIA comes out ahead of IWM. DIA has the lower expense ratio, higher dividend yield, and greater total return over the last five years. What’s more, it also has experienced less volatility, with its max drawdown being -21% as compared to -32% for IWM.

Therefore, many investors may favor DIA over IWM given its combination of positive attributes. However, IWM may still hold appeal for investors that are seeking diversification and greater exposure to small and mid cap stocks.
