Vulcan Draws 96% Calls on Small Volume, Martin Marietta Sits on Its 20-Day Average, Nucor Turns 60% Puts by the Close: Materials Data for Paving and Steel Bids (GTA Terminal, November 12, 2026)
Crushed stone, sand and steel are three of the biggest line items in any paving, foundation or structural bid. The public companies that produce them, Vulcan Materials, Martin Marietta and Nucor, report prices only once a quarter, but their stocks trade every day. GTA Terminal data from Global Traders Academy for November 11 and 12, 2026 shows the two aggregates producers holding bullish charts on light trading, while Nucor's options money swung toward puts by the end of Thursday's session.
What the data showed
Vulcan leaned heavily to calls, on small money: At midday on November 12, Vulcan Materials (VMC) had $23K in options premium: $22K in calls and $940 in puts, a 96% call share with a put/call volume ratio of 0.13. The stock, at $282.89, was above its 20-day average ($275.31) and its 50-day ($258.56). On November 11 only 250,836 shares traded off the exchanges, 0.4x normal and 18.5% of volume, the lowest share of the prior five sessions. The Vulcan Materials quote page tracks it.
Martin Marietta sat right on support: Martin Marietta Materials (MLM) traded at $523.92 at midday, just 0.3% above its 20-day average of $522.11, with resistance at the 20-day high of $571.63. Options premium was $16K, 64% in calls. Its off-exchange volume has thinned every session since November 5, from 706,094 shares to 226,375 on November 11, 0.5x normal. The Martin Marietta stock page has the levels.
Nucor turned put-heavy: At midday, Nucor (NUE) had $78K in premium, 55% in calls, a mixed tilt. By the evening scan, 40% of NUE's options premium was in calls and 60% in puts, a put-heavy lean, according to the GTA Wire's Nucor off-exchange check for November 12. That day 433,253 NUE shares traded off the exchanges, 0.7x normal but 44.6% of its volume. The stock stays in an uptrend, 9% below its 52-week high, with an RSI of 52. The Nucor quote and chart page follows it.
How to read it
Start with the size. A 96% call share sounds strong, but $23K of premium in a company of Vulcan's size is small, and the same goes for Martin Marietta's $16K. These are leans, not big institutional bets. What carries more weight is the agreement: in both aggregates names the chart, the options and the dark pools pointed the same way, and the level to watch is the 20-day average. For Martin Marietta that line is only 0.3% away, so it will be tested quickly.
Nucor is the mixed signal. Its chart leans bullish, but option money moved from a slight call lean at midday to 60% puts by the evening, and a high off-exchange share on below-normal volume says large holders were active without showing a direction. Puts can be protection after a run as easily as a bearish bet.
What it means for paving, site and steel contractors
Paving and site contractors: Steady aggregates stocks usually mean producers expect firm pricing. Build escalation language into bids that run into next season, and ask suppliers about locking prices on large jobs now.
Steel fabricators and erectors: A put lean in the largest U.S. steelmaker is a reason to watch, not to panic. If you buy plate or rebar on spot, compare a fixed-price contract against your recent purchase history.
Equipment buyers: Strong materials demand keeps loaders, crushers and haul trucks busy at quarries. Rental and used prices for that iron tend to stay firm when producers are confident.

A signal, not a guarantee
This data is a signal, not a guarantee. Small option totals can come from a handful of trades, and options premium shows where money went, not whether each trade was bought or sold. Nothing here is investment advice. All figures come from GTA's options flow data, dated as published.
