Executive summary
The quarter in four numbers
The read: a de-rating driven by discount rates and a rotation back into mega-cap AI — not a break in micro-cap company performance.

Performance scorecard
The smaller the company, the harder the quarter
Bars run left of the rule for losses and right of it for gains, on one scale. The top four rows are the size ladder; the bottom two split the Russell 2000 by style.

The quarter's defining gap
11.3 points separated mega-cap from micro-cap
The widest size spread of the cycle so far, in a single quarter — the Russell Top 50 up 4.1% against the Russell Microcap down 7.2%.
Money rotated out of AI-infrastructure names, small-caps and semis included, into sector laggards.
Software rebounded once fears of AI making it obsolete were read as an overreaction. Small-caps got a brief pause.
OpenAI's GPT-6 reignited chip demand; the Nasdaq hit a record on the 21st. Small-caps fell again.
Four moves in twelve days in mid-September: Brent over $100, the ten-year at 5.01%, the Fed hike, then the Nasdaq record.

Cycle context
One quarter inside an 18-month run
Total return from the 8 April 2025 market low to 30 September 2026. Micro-caps have compounded at roughly 1.7× the pace of large-caps across the whole move.
Historically, size-leadership cycles have run long: across eight completed cycles since 1931, the shortest lasted five years and the three longest ran 14 to 16 years.

Style
Value lost less — and is still winning
| Q3 2026 | Year to date | Since Apr 2025 low | |
|---|---|---|---|
| Russell 2000 Value | −4.9% | +17.0% | +63.4% |
| Russell 2000 Growth | −9.4% | +10.7% | +60.5% |
Value holding up in a drawdown is normal. Value leading in a bull cycle is not — and it has, on every horizon here. Momentum-led small-growth funds took the worst of it, with the leading category strategies down 14% to 17% in the quarter.

Drivers
Three dials moved against small, all quarter
Light bar = quarter start, dark bar = quarter end. Core PCE ran above 3% every month of 2026 with unemployment at 4.1% — the mix that kept policy tight and lifted the discount rate on every long-duration asset.

July and September both fell; August was the pause. The decisive week was the middle of September.

Sector story
Ten of eleven sectors fell. Energy alone added.
Industrials, Information Technology, Financials, Consumer Discretionary. Leading industry detractors: semiconductors and semicap equipment, biotechnology, machinery, banks, construction and engineering.
Energy, carried by oil, gas and consumable fuels as crude ran 29% higher through the quarter.
Nine of eleven sectors positive, led by Information Technology, Industrials and Health Care. Only Consumer Discretionary and Utilities detracted, both modestly.
Semis and semicap equipment led the year to date and topped the Q3 detractor list.

Inside the one winning sector
Energy led — refiners ran away with it
Average Q3 2026 return by energy sub-industry. The spread between refiners and pipelines was the widest inside any sector this quarter.
Not all of energy worked. Natural-gas producers fell — Comstock Resources −17.4%, EQT −8.4%, Antero −5.0% — and traditional pipeline operators lost ground, with Enbridge −13.1% and TC Energy −11.9%.

Named movers
Tankers and refiners up. Data-centre builders down.
Argan and Sterling were among the strongest first-half performers in the small-cap data-centre build. Both gave back the bulk of those gains in one quarter.

Fundamentals
Prices fell. The businesses did not.
| Per-share growth, Q3 2026 | Russell 2000 | Russell 1000 |
|---|---|---|
| Earnings per share | +19.5% | +10.2% |
| Free cash flow per share | +11.2% | +6.6% |
| Sales per share | +2.9% | — |

Valuation
Micro-cap is the cheapest corner of the US equity market
On median EV/EBIT excluding negative-EBIT companies, Russell Microcap Value, Russell Microcap and Russell 2000 Value sit just below or slightly above their own 25-year averages. Large-cap valuations still have a long way to fall to reach theirs.
Micro-cap value, micro-cap core and small-cap value — all close to their long-run medians rather than stretched.
Large- and mega-cap, where index concentration also sits. Higher rates press hardest on the highest multiples.
Small-cap sits between two crowded allocations — mega-cap equity and illiquid private markets — both at valuation extremes.
Russell Microcap held 1,375 names at the June reconstitution, averaging about $292m in market cap.

Capital markets
Issuance stayed open — and got selective
Volume fell back from an exceptional second quarter but stayed well ahead of Q1. Healthcare was 45% of the Q3 IPO count, with technology and industrials at 15% each.
Convertibles in Q3 alone. 2026 has passed 2025's full-year record, on pace for about $180bn.
Follow-ons and block trades, against roughly $34bn in the same quarter last year.
Entered the Russell 1000, 2000 and Microcap indexes on 21 September — a real flow event at this size.

Outside the US
Where the AI trade is thinner, small still won
Third quarter 2026. Up 11.4% year to date.
Essentially flat. Up 14.5% year to date.
Non-US small-caps outperformed their large-cap peers for a second straight quarter — the mirror image of the US result.
That decoupling is the cleanest available evidence that the US small-cap drawdown was about the composition of the US market — mega-cap AI concentration and a rate shock — rather than a global repricing of small companies.

Insights
What changes in how you read a micro-cap
With cash earning a real return again, net-cash companies have an advantage they have not had since before 2009 — and the optionality to buy assets while rivals refinance.
At a 5% ten-year, the dividing line in micro-cap is refinancing risk: leverage, covenant headroom and 2027 maturities now matter more than revenue growth.
Record convertible issuance and 36 new index entrants mean more dilution, lock-ups and inclusion flows to track per name — the detail lives in the filings.
A cohort of quality small-caps has gone from take-private target to buyer, picking up businesses cheaply from private equity firms that need liquidity.
The practical shift: in a 4% cash world, dispersion inside micro-cap widens. Index-level calls get less useful and name-level balance-sheet work gets more.
MicroCap Desk analysis; Royce Investment Partners, Aug 2026.
Q4 2026
Five catalysts to track
| Catalyst | Timing | Why it matters for micro-cap |
|---|---|---|
| December FOMC | Mid-December | The median dot implies one more hike. A hold would be the cycle's first dovish surprise. |
| Russell reconstitution | December | First December rebalance under the semi-annual schedule. Membership changes drive real flow. |
| Q3 earnings season | Oct–Nov | Tests whether the per-share growth holds once the full small-cap universe reports. |
| Oil and the Gulf | Ongoing | Brent above $100 feeds inflation, yields and input costs. The main two-way risk. |
| M&A and take-privates | Ongoing | A wide valuation gap plus liquidity-hungry sponsors is the setup for deal activity. |
Base case into year end: dispersion rather than a clean directional call — cheap valuations and accelerating earnings against a hawkish Fed and an unresolved energy shock.
