Steel vs. Stone: What GTA Terminal Data Shows Big Money Doing in Nucor, Steel Dynamics and Vulcan Materials (November 2026)

Steel and crushed stone show up in almost every bid a contractor writes: rebar, beams, trailer frames, base rock. When those prices swing, so do margins on fixed-price jobs. Three stocks give a running read on that side of the business: Nucor and Steel Dynamics, two of the largest U.S. steelmakers, and Vulcan Materials, one of the largest U.S. producers of crushed stone, sand and gravel. In the first week of November 2026, GTA Terminal data from Global Traders Academy showed traders cooling on steel while staying more upbeat on aggregates.

Nucor: a split market that tilted toward puts

On November 6, Nucor shares were up 2.6% at $252.06 by midday, according to GTA Terminal data. Of the $2.1 million in options premium traded in NUE by then, $1.0 million went into calls and $1.1 million into puts, so only 47% of the money was in calls. The midday numbers are in GTA Wire's Nucor options split for November 6.

By the evening scan, the lean had grown clearer: 63% of NUE's options premium was in puts. Off the exchanges, 677,462 Nucor shares traded in dark pools on November 6, 1.2 times the stock's 20-session average and 40.6% of all its volume. GTA's chart read showed a mixed trend, with Nucor below its 50-day average, above its 200-day and about 15% under its 52-week high. The full session is in GTA Wire's report on Nucor's off-exchange trading on November 6.

Steel Dynamics: a sharp drop and a bearish chart signal

Steel Dynamics had a rough Thursday. On November 5 the stock closed down 7.59% at $221.90. Options traders were close to balanced that day: of $2.7 million in premium, $1.6 million went into calls and $1.1 million into puts, a put/call volume ratio of 0.64. Dark pool activity told a louder story, with 686,506 STLD shares trading off the exchanges, 1.8 times the normal level. GTA Wire's Steel Dynamics closing flow report for November 5 has the details.

The GTA Proprietary Pattern Model flagged a bearish double top on the STLD daily chart, with the stock breaking below the pattern's key level at $231.25. Confidence: Level 3 of 5. One day later, on November 6, the options money moved to agree with the chart: 64% of STLD premium went into puts, while dark pool volume calmed down to 373,516 shares, 0.9 times normal.

Vulcan Materials: aggregates held up

The picture for crushed stone was different. In the latest scan reported on November 7, 60% of Vulcan Materials options premium was in calls and 40% in puts, a call-heavy lean. GTA's chart read showed VMC in an uptrend, above both its 50-day and 200-day averages and about 15% below its 52-week high, with an RSI of 66. Dark pool volume on November 6 was 480,499 shares, 0.9 times normal and 45.7% of the day's volume. GTA Wire's Vulcan Materials dark pool check covers the numbers.

What this means for contractors and fleets

• Steel sentiment cooled. Put-heavy flow in both steelmakers and a bearish chart signal on Steel Dynamics point to traders expecting softer steel stocks in the near term. That does not guarantee cheaper steel, but it is worth watching before you lock prices on a long bid.

• Aggregates look steadier. Call-leaning flow and an uptrend in Vulcan suggest traders expect demand for stone, sand and gravel from road and site work to hold up.

• Mixed signals call for flexible bids. When steel and aggregates point different ways, consider shorter price-hold windows on steel-heavy jobs and escalation clauses where your customers allow them.

• Buying steel-heavy equipment. Trailers, truck bodies and attachments carry a lot of steel. If steel softens, list prices can follow with a lag, so it can pay to get quotes now and compare again in a few weeks if your timeline allows.

A word of caution

Options flow and dark pool data are a signal, not a guarantee. Put buying can be a hedge rather than a bet, and one week of trading does not set a trend.
