Applied Materials Options Price a 10.3% Weekly Swing as Lam Research Closes 59% Puts: Chip Equipment Data for Fab Contractors (GTA Terminal, November 12, 2026)

Every new chip plant is a construction project first: steel, concrete, cleanrooms, power, process piping and a long list of specialty contractors. The companies that sell the tools inside those plants, Applied Materials and Lam Research, are a useful early read on how hard chipmakers plan to spend. After the close on Thursday, November 12, 2026, GTA Terminal data from Global Traders Academy showed the options market bracing for a large move in Applied Materials, while Lam Research ended the day with more money in puts than calls.

Applied Materials: a 10.3% swing priced in for one week

Applied Materials closed the session at $380.95, up 19.3% over the past week. The options market was pricing a move of about plus or minus 10.3% by the November 20 expiration, a range of roughly $341.55 to $420.35. Further out, the December 18 expiration priced plus or minus 15.7%, or $321.30 to $440.60. That is a wide band for a single week, as the Applied Materials week-ahead report points out.

Positioning was split. In the last session, 61% of the contracts traded for this week's expiration were calls, but across all expirations the put/call open-interest ratio was 1.31, more puts than calls held open. Dark pools were busier than usual: 3,299,852 shares traded off the exchanges on November 12, 1.2x the 20-session average and up from 2,247,735 the day before. The stock sat just under its 20-day average of $384.87 and well under its 50-day average of $439.22, still 48% below its 52-week high. Track it on the AMAT price and flow page.

Lam Research: 59% puts into the close

Lam Research closed down 0.89% at $233.78. Over the session, $117.9M in options premium traded: $48.6M in calls and $69.3M in puts, so 59% of the money was in puts. By contracts, the put/call volume ratio was 0.76, meaning more call contracts traded but put contracts carried more dollars. Ten strikes traded above their open interest, a sign of fresh positions. The Lam Research closing flow report lists the session in full.

Off-exchange trading was light: 2,844,225 shares on November 12, 0.6x normal and 34.6% of volume, down from 7,215,099 on November 6. The stock was 1.1% below resistance at its 20-day average of $236.25, with the nearest support at $184.24, 21.2% below, and 47% below its 52-week high. See the Lam Research quote page for updates.

What it means for fab contractors and suppliers

• Uncertainty, not a verdict. A 10.3% expected weekly move and a put-heavy close at Lam say investors are unsure about chip equipment spending, even after a strong week. Contractors bidding on fab work should expect project timing to stay fluid.

• Specialty equipment needs firm backlogs. Aerial lifts, welding rigs, pipe threading and cleanroom tools are expensive. Match the purchase to signed contracts rather than to headlines about new plants.

• Consider shorter terms or rentals for one-off jobs. If a single fab project drives the need, a rental or a shorter loan term limits the risk if the next phase slips.

• Watch both names together. When Applied's call lean and Lam's put lean converge, that is a cleaner read on chipmaker spending than either alone.

A word of caution

An expected move is the market's estimate, not a forecast, and options premium shows where money went, not whether each trade was a bet or a hedge. Treat this as a signal, not a guarantee. Nothing here is investment advice.

Equipment financing for specialty contractors

BFC Equipment Loans works with electrical, mechanical and specialty contractors to finance lifts, welders, generators and other job-site equipment. When the contract is signed, apply for equipment financing and keep the project moving.
