It’s Not Oil or Solar

Friday’s close left traders holding two data points that refuse to reconcile. Fastenal posted August total sales of $812.1 million, up 16.6% year-over-year on both a total and daily sales basis. The gain accelerated from 15.5% in July, marking the company’s 14th straight month of double-digit growth and its strongest result since July 2022. At almost the same moment, the ISM Manufacturing Employment Index registered 51.2% in August, 1.6 percentage points lower than July’s reading of 52.8%. Both numbers are credible. They are also telling very different stories.

What Happened

Fastenal’s report left almost no room for bears to hide. Growth accelerated from July across all geographies, and Fastenal’s two largest end markets, which together comprise nearly 77% of total sales, both strengthened. Contract customers, the company’s deepest and stickiest relationships, saw daily sales climb 19%. The acceleration across all geographies, both major manufacturing end markets and direct materials adds another encouraging data point for industrial demand heading into the end of the third quarter.

The one notable soft spot: non-residential construction, where growth dropped to 9.6% from 16.9% in July. That is worth noting for traders watching peers like GWW and MSM, given how much non-residential construction contributes to their mix.

Meanwhile, the broader jobs picture looked better than feared. The manufacturing sector added 16,000 jobs in August, well above the LSEG estimate of 5,000. But the ISM employment sub-index still slipped, and the longer-run labor picture in manufacturing remains uneven. Manufacturing payroll employment in August 2026 was lower than it was in January 2025.

Why It Happened, and Why the Conflict Matters

The honest answer is that both data points can be correct simultaneously. Fastenal’s growth does not necessarily mean the industrial economy is expanding at a mid-teens rate across the board. Pricing contributed about 290 basis points to second-quarter growth, and the company has repeatedly pointed to market share gains with larger customers as a major driver of its outperformance. The monthly report does not provide a price-volume breakdown, so August’s 16.6% gain cannot be isolated into those components. Some portion of the number is Fastenal winning business that used to go elsewhere.

That is precisely the distinction professional traders need to make. A company posting mid-teens sales growth is not the same as an industry posting mid-teens volume growth. Fastenal is gaining share by embedding itself more deeply in customer purchasing, inventory management and procurement workflows. The ISM employment index, by contrast, reflects what purchasing managers across hundreds of companies believe is happening to their own headcount. When those two signals diverge, dismissing either one is usually a mistake.

How Professionals Might View It

Experienced traders treat conflicting data as a positioning signal, not a reason to stand aside. The relevant question is not which data point is correct. It is what the market is currently priced to believe, and which direction a resolution of the conflict would push prices.

W.W. Grainger reported second-quarter daily, organic constant-currency sales growth of 13.7%, corroborating the Fastenal demand signal from a different angle. That double confirmation matters. If the ISM employment softness were reflecting genuine demand deterioration, Grainger would have seen it too.

The ISM number, on the other hand, may be capturing something real about the labor side of manufacturing without saying anything definitive about volumes. Companies can produce more while adding fewer workers, particularly after years of productivity investment. Neither reading cancels the other.

What Comes Next

The September 11 CPI release is the next major catalyst. If inflation continues to cool, the Fed’s flexibility increases and cyclical industrials tend to benefit. If prices prove stickier than expected, the cost-pass-through dynamics at Fastenal and Grainger get more complicated, especially given the margin pressure from unfavorable net price/cost that Fastenal flagged in Q2.

Watch FAST’s relative strength against MSM. MSC Industrial has been struggling with slower demand in its metalworking end markets. If Fastenal’s contract momentum is genuinely demand-driven rather than purely share-gain-driven, MSM should see some catch-up. If it does not, that tells you something important about where the volume is really coming from.

The Trader’s Lesson

When two credible data sources disagree, the productive move is not to pick a side. It is to ask what mechanism would make both true at once, and then look for confirming or disconfirming evidence. Fastenal gaining share while ISM employment softens is not a contradiction. It is a coherent picture of an uneven recovery, where execution beats matter more than the macro tide. Trade what you can verify, and stay cautious about extrapolating one company’s results to an entire sector.
