NL Industries enters the week of its next earnings event — scheduled for May 13 — with short interest creeping higher and options traders carrying a notably defensive lean.
The most telling shift in positioning is the quiet but persistent rebuilding of short interest over the past month. Shares short have climbed roughly 9% over 30 days, rising from around 136,000 in early April to 152,304 by May 5. The move is modest in absolute terms, but the direction is consistent: after a sharp drop around April 9-10, shorts have added steadily back. The lending market remains extremely loose, however. Cost to borrow is running at just 0.61% annualised — cheap even after a 36% jump on the week — and availability shows no sign of tightening pressure. With a short score of 33 and a utilisation rank in the 74th percentile, the borrow dynamic reads as comfortable rather than strained.
Options positioning tells a more cautious story. The put/call ratio has climbed to 1.45, above its 20-day average of 1.25, though the z-score of 0.37 keeps the reading well within one standard deviation of recent norms. The ratio is far below its 52-week high of 12.87, which sets an extreme reference point, but the sustained above-average PCR over the past two weeks does suggest investors are carrying more downside protection into the May 13 print than they were a month ago, when the ratio was sitting nearer 0.21.
The Street picture for NL is thin and dated. The only available analyst coverage is a Barclays Underweight maintained in September 2024 — nearly 19 months ago — with a $6.00 target that sits close to the current price of $5.86. Given the staleness, it carries little actionable weight. Valuation data is similarly limited; the P/E multiple of 8.2x has drifted slightly lower over the past 30 days, but the underlying figures date to early 2021 and should be treated with caution. An EPS surprise score in just the 6th percentile underscores that NL has not been a name that consistently beats expectations.
One structural feature of the stock is worth noting: Contran Corporation holds 82.7% of shares, leaving an extremely thin free float. That concentration explains why short interest in absolute share terms looks small — the tradeable universe is narrow — and why any shift in borrow conditions or institutional appetite can have outsized effects on price. Among the broader holder group, Dimensional Fund Advisors recently added a modest 21,755 shares and BlackRock added 5,861, but these are incremental moves against a largely immovable controlling stake. Peer names such as ACCO and CMPR have had a notably stronger week — ACCO up nearly 19% and CMPR up 11% — while NL has slipped 1.8%, a divergence that may reflect the stock's illiquidity as much as any fundamental view.
Recent earnings history offers thin but directionally consistent context. The last two confirmed prints both produced negative one-day reactions, with a 3% drop on March 9, 2026 extending to a 4.3% five-day loss. The prior event in March 2025 was the exception, producing a 3% gain on the day. With the next event one week away, the combination of a steadily rebuilding short base, above-average put/call ratio, and a tight float makes the May 13 release the clearest near-term focal point for anyone watching this name.
