Two significant option trades in Micron Technology and Nvidia have caught market attention, raising questions about sentiment in the semiconductor sector. On October 9, 2026, data from ThinkOrSwim and SpotGamma showed an unusually high volume of put options in the semiconductor ETF SMH, with over 180,000 puts traded by midday versus 50,000 calls. The premium on puts was $46 million, nearly double the $26 million placed on calls, indicating a notable bearish stance among traders.

Nvidia saw one of the largest single-stock option trades of the day, with a buyer acquiring 100,000 January 15, 2027 expiration puts at a strike price of $180 for $21 million. This position suggests a bet on a sharp decline of approximately 22% in Nvidia’s share price by mid-January. Meanwhile, Micron trades were even more striking. A complex series of deep in-the-money put contracts expiring in June 2028, mostly purchased at strike prices between $2,250 and $2,500, created a synthetic short position valued at about $14.5 million with an options delta near -1.

The preference for deep in-the-money puts over shorting shares indicates traders are seeking defined risk exposure, likely due to the high cost of borrowing the stock or a desire to limit losses to the option premiums paid. This strategic use of options might signal growing caution about the chip sector’s near-term prospects. Market analysts noted that interpreting bid-ask spreads in these trades is complex, especially for far out-of-the-money options with low liquidity, but the scale and nature of the trades remain an important signal.

Overall, these large bearish option positions in key semiconductor players like Micron and Nvidia underscore investor wariness despite the sector’s strength earlier in the year. The surge in put buying relative to calls on the semiconductor ETF and the Invesco QQQ Trust points to increased hedging or downside speculation. As the semiconductor industry faces challenges ranging from supply chain issues to market demand fluctuations, these trades could foreshadow more volatility ahead.
