Lam Research, Applied Materials and KLA Rally Up to 7.7% as Calls Lead: GTA Terminal Data for Fab and Clean-Room Contractors (November 11, 2026)

The companies that build chipmaking equipment jumped on Wednesday, November 11, 2026, and options traders put far more money behind the move than a day earlier. According to GTA Terminal data from Global Traders Academy, Lam Research and Applied Materials each rose 7.7% by late morning, KLA gained 6.4%, and all three drew most of their options premium into calls. For electrical, mechanical and specialty contractors who work on semiconductor fabs and clean rooms, these three stocks are a running gauge of how much the industry plans to spend on new tools and buildings.

The numbers, stock by stock

GTA's reports, all published between 11:57 AM ET and noon, showed:

• Lam Research: up 7.7% at $239.40. Premium of $32.9M, with $27.3M in calls (83%) and $5.7M in puts; put/call volume ratio 0.47. The largest unusual trade was 1,194 call contracts expiring November 20, about $720K in premium against 985 contracts of open interest. Source: GTA's November 11 Lam Research options flow report.

• Applied Materials: up 7.7% at $401.10. Premium of $31.9M, with $23.7M in calls (74%) and $8.2M in puts; put/call volume ratio 0.52. The largest unusual trade was 326 call contracts expiring December 11, about $1.9M in premium against just 12 contracts of open interest, a sign of a new position. Source: the Applied Materials flow report from the same morning.

• KLA: up 6.4%. Premium of $4.3M, with $3.6M in calls (83%); put/call volume ratio 0.42. The largest unusual trade was 406 call contracts expiring January 19, 2029, about $2.1M in premium against 85 contracts of open interest, a long-dated bet.

How this compares with Tuesday

On Tuesday, November 10, the same three stocks were already call-leaning: KLA at 85% calls, Lam Research with $13.3M of $17.9M in calls, and Applied Materials at 61%. What changed on Wednesday was the size of the bets and the direction of price. Lam Research premium was $32.9M by late morning, against $17.9M in GTA's November 10 report, and Applied Materials' call share rose from 61% to 74%, with the stocks moving up sharply instead of sliding.

The catch: still deep in downtrends

A big up day does not erase the bigger picture. GTA describes all three in downtrends, below their 50-day and 200-day averages: Lam Research 45% below its 52-week high, Applied Materials 46% below, and KLA 47% below. RSI readings of 53 to 57 sit in neutral territory. The GTA Proprietary Pattern Model had no live setup on any of the three daily charts. Dark-pool trading on November 10 was moderate: 4,050,353 Lam Research shares (35.0% of volume), 2,014,369 Applied Materials shares (31.8%) and 3,941,211 KLA shares (34.5%). You can follow the group on the Lam Research stock page, along with Applied Materials and KLA, on the GTA Terminal.

What it means for fab and clean-room contractors

• One strong day is not a spending cycle. Chip equipment makers are still far below their highs, which tells you the market has been cautious about fab spending. A sustained recovery would show up as several weeks of call money and a break above the 50-day averages, not one rally.

• Bid carefully on fab work. Fab projects can be delayed or resized when chipmakers adjust plans. Build schedule flexibility and clear change-order terms into contracts.

• Specialized gear holds its value. Clean-room lifts, high-purity piping tools and test equipment serve other industries too, from pharmaceuticals to data centers. Financing that equipment is less risky when it can move to other projects if a fab slows down.

• Watch for follow-through. New long-dated call positions, like KLA's 2029 trade, show some investors positioning for years, not days. That fits the long timelines of fab construction.

A word of caution

Options flow and dark-pool data are a signal, not a guarantee. Rallies inside downtrends often fade, and these midday numbers can change by the close. This article is general business information, not investment advice.
