IJR vs IWM: IJR wins on cost and quality, IWM on trading depth. IJR charges 0.06% a year against IWM’s 0.19%, admits only profitable companies and carried a 1.08 beta to IWM’s 1.27. That gap matters now: October CPI, released November 10, 2026, beat forecasts and lifted the 2-year Treasury yield 17 basis points to 4.74%, and markets fully price a December Fed hike.

Key takeaways

  • IJR costs $6 a year per $10,000 invested; IWM costs $19.
  • Morningstar counts about 40% of Russell 2000 companies as unprofitable; S&P 600 additions must show profits.
  • Ten-year returns to Sept. 30, 2026 were nearly tied: 9.78% for IJR, 9.75% for IWM.

Why is the IJR vs IWM question back after the hot CPI?

Because rates just jumped, and small caps carry more floating-rate debt and more money-losing companies than large caps. The Bureau of Labor Statistics said on November 10, 2026 that October CPI rose 0.4%, with core up 0.3%. Both beat the 0.3% and 0.2% forecasts, per Saxo.

Saxo called it the third straight upside inflation surprise. Its November 11 note says markets now fully price a December hike, plus two more by next June. Fed Governor Christopher Waller backed a 25-basis-point December move and said 50 could be considered.

Bonds reacted hard. The 2-year Treasury yield rose 17 basis points to 4.74% on November 10, and the 10-year rose 11 basis points to 4.99%, per Saxo. Bond markets were closed on November 11 for Veterans Day, so those are the latest closes.

Stocks shrugged it off on November 11. The Russell 2000 rose 0.9% to 2,846.26 and the S&P 500 gained 1.3% to 7,619.38, according to AP’s closing tally. Small caps still lead for 2026: up 14.7% year to date versus 11.3% for the S&P 500.

A hiking cycle is exactly when the index inside your small-cap ETF matters. Hikes punish companies that borrow at floating rates and have no earnings to cover the bill. If you are weighing cash instead, our 2-Year Treasury vs T-Bills breakdown covers that side of the trade.

How do IJR and IWM compare on fees and specs?

IJR is cheaper, bigger and less volatile; IWM is broader and has the slightly tighter spread. The iShares Core S&P Small-Cap ETF charges 0.06% and holds 636 stocks. The iShares Russell 2000 ETF charges 0.19% and holds 1,980. Both launched May 22, 2000.

The size ranking surprises people. IJR, at $103.5 billion, is the larger fund. IWM, at $74.6 billion, is simply the ticker traders know best.

IWM’s real edge is breadth. It owns more than three times as many companies, money-losers included. Its largest sector is health care at 20.33%, a corner of small caps crowded with early-stage biotech. IJR’s largest is financials at 18.61%.

Watch the valuation quirk. IWM shows the lower P/E, 18.09 to IJR’s 18.98. But a P/E ratio says nothing about companies with no earnings to divide by, and IWM holds far more of them. As with RSP vs VOO, the index rules decide what you actually own.

Is IJR or IWM cheaper to hold?

IJR, by a wide margin. The IWM expense ratio of 0.19% is more than three times IJR’s 0.06%. On a $10,000 position that is $19 a year versus $6, a 13-basis-point gap. IJR’s higher dividend payout claws back a little of that in taxable accounts, but not most of it.

The fee math in dollars

Position sizeIJR at 0.06%IWM at 0.19%Annual gap
$10,000$6$19$13
$50,000$30$95$65
$100,000$60$190$130
Annual expense ratio cost at a constant balance. Expense ratios from iShares, November 2026.

The arithmetic: $10,000 × 0.0006 = $6, and $10,000 × 0.0019 = $19. Hold $100,000 for 10 years at a flat balance and fees total $600 for IJR versus $1,900 for IWM. That is a $1,300 difference before any compounding.

The tax drag offsets part of it

IJR pays out more. Its 12-month trailing yield was 1.26% on Sept. 30, 2026, versus 0.98% for IWM, per iShares. On $10,000, that is $126 of distributions versus $98.

Assume those dividends are taxed at 15%. IJR’s tax bill is $18.90 and IWM’s is $14.70, a $4.20 gap. Add fees and taxes: $24.90 a year for IJR, $33.70 for IWM. IJR still comes out $8.80 ahead per $10,000.

In an IRA or 401(k), the tax line disappears and IJR keeps the full $13 advantage.

Does the S&P 600 profit screen matter when rates rise?

It matters more than usual. S&P Dow Jones Indices requires a company’s last four quarters of reported earnings, and its latest quarter, to be positive before it can join the S&P 600. The Russell 2000 has no such test, so IWM owns the unprofitable companies that higher borrowing costs squeeze hardest.

Russell 2000 vs S&P 600: why money-losers are the rate-hike problem

About 40% of Russell 2000 companies generate no earnings, according to a Morningstar analysis cited by IBTimes in June 2026. Two decades earlier, that share was 17%.

Smaller companies lean more on bank loans and floating-rate debt than large caps do, so their interest costs reset quickly when the Fed moves. A company without profits pays that higher bill from cash, new borrowing or new shares.

It shows up in the risk numbers. IWM’s three-year beta was 1.27 on Sept. 30, 2026, versus 1.08 for IJR, per iShares. Beta measures how hard a fund swings relative to the broad market.

Where the screen falls short

Be skeptical of the quality label. The profit test decides who gets in; it is not an annual audit of every holding. A company that slides into losses after joining can stay.

It also did not help lately. Over the three years to Sept. 30, 2026, IWM returned 17.59% a year to IJR’s 14.74%, as speculative names rallied. And the S&P 600 is run by a committee, which adds judgment calls that mechanical Russell rules avoid.

Which has performed better, IJR or IWM?

Over the long run, IJR, but by less than its reputation suggests. Since both launched on May 22, 2000, IJR returned 9.73% a year to IWM’s 8.35%, according to iShares data through Sept. 30, 2026. Over the last 10 years, the two are nearly dead even.

The deeper history favors the profit screen. An S&P Dow Jones Indices study found the S&P 600 returned 10.72% a year from January 1994 to November 2016, versus 8.84% for the Russell 2000, with lower volatility.

The skeptical read: that study comes from the index’s owner, and the past decade is close to a tie. IJR’s repeatable edge is the 13-basis-point fee gap. Its quality edge is real but uneven.

Which small-cap ETF fits which investor?

Long-term holders should weigh cost and quality, and both favor IJR. Traders who need hedging tools and deep liquidity lean toward IWM, because the Russell 2000 is the benchmark most small-cap futures and options track. Taxable investors still come out ahead with IJR on the numbers above, despite its bigger payout.

What to watch next

Four dated events could shift this comparison before year-end: a Russell list that changes what IWM owns, the Fed decision, the next CPI print and the day the reconstitution takes effect. All four land between November 13 and December 11, 2026.

  • November 13, after the close: FTSE Russell publishes preliminary additions and deletions for the Russell reconstitution, the first December rebalance in more than three decades.
  • December 8–9: The FOMC meets, with new economic projections. Markets price a hike.
  • December 10, 8:30 a.m. ET: November CPI, per the BLS schedule.
  • December 11, after the close: Russell changes take effect, and IWM must trade to match its index.

One more skeptical note on IWM: Russell changes are published weeks ahead and follow set rules, which makes them a known target for traders who buy additions early. The index fund pays that cost, and a semi-annual schedule now gives traders two shots a year instead of one.

IJR vs IWM: frequently asked questions

Is IJR cheaper than IWM?

Yes. IJR’s expense ratio is 0.06% and IWM’s is 0.19%, per iShares. That is $6 versus $19 a year on a $10,000 position.

What is the difference between the S&P 600 and the Russell 2000?

The S&P 600 is picked by a committee and requires positive trailing earnings to join. The Russell 2000 follows size rules with no profit test. IJR held 636 stocks and IWM held 1,980 as of Oct. 23, 2026.

Do Fed rate hikes hurt small caps more than large caps?

They tend to, because smaller firms rely more on floating-rate borrowing and more of them lack profits. About 40% of Russell 2000 companies generate no earnings, per a Morningstar analysis.

Has IJR outperformed IWM?

Since both launched on May 22, 2000, yes: 9.73% a year versus 8.35% through Sept. 30, 2026. Over 10 years they are nearly tied at 9.78% and 9.75%, and IWM led over three years.

Which pays a higher dividend, IJR or IWM?

IJR. Its 30-day SEC yield was 1.58% on Sept. 30, 2026, versus 1.18% for IWM, per iShares.

When is the December 2026 Russell reconstitution?

FTSE Russell publishes preliminary lists on Nov. 13, 2026, and the changes take effect after the close on Dec. 11, 2026.

The bottom line

On measurable attributes, IJR is the better small-cap ETF to hold: under a third of the fee, a profit test for new members, a lower beta and a higher yield. IWM earns its place as a trading tool and as the unscreened bet on every small cap, money-losers included.

The hot October CPI raised the stakes of that difference. If the Fed hikes on December 9 as markets price, companies with no earnings face the steepest refinancing bill, and IWM holds them by design. That is not a call on either fund’s price; it is what each index is built to own.

The trade-off is simple. Pay IWM’s extra 13 basis points a year only if you need its liquidity or want the full, unfiltered Russell 2000.
