Summary
• Teradyne (TER) rockets 7.57% to $208.21, piercing its 52-week high of $208.80
• Options frenzy: 221,539 contracts traded on the 2026-01-09 expiry, with 472-volume call at $205 strike

Teradyne’s intraday surge defies short-term bearish trends, with options data and technicals painting a complex picture. The stock’s 7.57% jump—its largest single-day move since 2025—has triggered a cascade of call options trading, particularly in the 205-220 strike range. With the 200-day MA at $118.99 and Bollinger Bands squeezing near $196.87 midline, traders are scrambling to decode whether this is a breakout or a countertrend reversal.

Options Volatility and Short-Term Gamma Play Ignite Teradyne
The explosive 7.57% rally stems from a confluence of technical triggers and options positioning. The $205 call option (TER20260109C205) saw 221,539 contracts traded, with a 390% price change ratio and 30.29% leverage ratio, indicating heavy gamma-driven buying. Short-term traders are capitalizing on the stock’s proximity to its 52-week high ($208.80) and the 200-day MA ($118.99) acting as a dynamic support. The RSI at 37.09 suggests oversold conditions, while the MACD histogram (-1.29) indicates bearish momentum, creating a tug-of-war between short-term sellers and long-term bulls.

Semiconductor Equipment Sector Gains Momentum as Teradyne Outpaces Peers
The Semiconductor Equipment sector, led by Keysight (KEYS) at +1.74%, shows modest gains compared to Teradyne’s 7.57% surge. While the sector’s leveraged ETF (TECL) rose 0.82%, Teradyne’s options activity suggests stronger conviction in its near-term trajectory. This divergence highlights Teradyne’s unique positioning in test and measurement equipment, where recent product cycles and supply chain dynamics may be outpacing broader sector trends.

Break Above $208.80 Could Ignite Multi-Bagger Potential
Teradyne’s 7.57% surge suggests a potential breakout from its long-term bullish trend, but the bearish MACD histogram (-1.29) warns of short-term resistance. Traders should monitor the 200-day MA ($118.99) as a critical support level and the 52-week high ($208.80) as a psychological barrier. If the stock closes above $208.80, the TER20260109C205 call could deliver exponential returns. Sector leader Keysight (KEYS) at +1.74% indicates broader semiconductor strength, but Teradyne’s options frenzy suggests it’s the prime mover. Watch for a $208.80 close or a breakdown below $196.87 midline to confirm direction.
