Fastenal Company heads into the final trading day of April with a stretched valuation, a soft Q1 earnings reaction, and short sellers nudging their positions higher — a muted but notable setup for a stock that commands a premium price for reliable growth.
The clearest near-term catalyst already passed. Fastenal reported Q1 on April 13 and the stock dropped 9.3% on the day, extending to a 7.3% loss over the following five sessions. That one print wiped out most of the year's standing, and the stock closed Wednesday at $43.71 — down 2.5% on the week and 2.8% on the month. A separate April 23 event registered only a -0.3% one-day move, suggesting the market had already done most of its repricing. The next earnings date is now pencilled for July 13.
The positioning picture is benign, not charged. Short interest ticked up 8% in a single session on April 28 to 2.35% of the free float, pushing the week-on-week move to roughly 3%. That sounds brisk in isolation, but at 27 million shares short, the absolute level remains modest. Availability is extremely loose — with available shares running at more than 15 times current short interest — which means new shorts face no friction entering or exiting the trade. Cost to borrow has actually fallen, now at 0.41% versus 0.51% a week ago, a multi-month low. The ORTEX short score edged up to 35.3 on April 28 from 33.9 earlier in the week — directionally higher, but still well within the neutral range. Options tell a different story: the put/call ratio has dropped to 1.11, roughly two standard deviations below its 20-day average of 1.20, meaning hedging demand has retreated sharply since early April. That divergence — rising short interest alongside easing options defensiveness — is worth noting. Shorts are adding quietly while options traders are removing downside protection.
The valuation debate is where bulls and bears diverge most sharply. Fastenal trades at 35x trailing earnings and an EV/EBITDA of 24x, both of which have compressed slightly over the past month — the P/E is down roughly 0.9 turns in 30 days. That derating is modest relative to the April sell-off, suggesting the multiple remains elevated for what is, at its core, a slow-growth industrial distributor. Revenue grew 12.4% year-on-year in the latest quarter, gross margins held at 44.6%, and the company generated $378 million of operating cash flow. The balance sheet is clean with net debt of just $137 million. Bulls can point to consistent execution; bears — and Wolfe Research (Underperform) and Bernstein (Underperform, $38 target) are in that camp — argue that a mid-30s P/E for a business growing at this rate is simply too much. The Street consensus sits at Hold, with Baird (Outperform, $50) holding the high-conviction bullish flag after trimming its target from $52 following earnings. Barclays maintained Equal-Weight and nudged its target to $45 on April 17, just above the current price. Factor scores add modest support: the dividend score ranks in the 82nd percentile, and EPS surprise lands in the 64th percentile, but forward EPS growth expectations rank only in the 27th percentile — the Street sees limited acceleration from here.
Institutional ownership is deep but largely passive. Vanguard and BlackRock together hold roughly 22% of shares. Wellington Management added a notable 8.6 million shares as of February, a move worth watching for follow-through when Q1 13-F filings arrive. Insiders have been net sellers in the 90-day window, with the March sale of $1.75 million by an independent director adding to a pattern of light supply from the table. A cluster of modest director purchases in November 2025 — four directors each buying around 1,000 shares near $40 — is the most recent expression of insider conviction, though those entries are now underwater.
Close peers had a mixed week. GWW fell 0.8% on the week while AIT and MSM closed up 2.3% and 4.2% respectively — meaning FAST underperformed most of its distribution peers after the earnings hit. The July 13 print, and whether Q2 revenue growth can sustain the double-digit pace, is now the clearest yardstick for whether that valuation gap begins to close or widen further.
