Two huge Micron and Nvidia trades may signal chips outlook

• In Nvidia, a trader purchased 100,000 put contracts at the $180 strike for $21 million, requiring a 22% decline by January 15 expiry to profit
• Micron saw approximately $270 million in premium tied to likely put-buying, including deep in-the-money puts expiring in June 2028 forming a $14.5 million bearish spread position
• The SMH semiconductor ETF's put-to-call ratio climbed to 1.95, the highest since early August, with $46 million in put premium versus $26 million in call premium traded by midday

Summary: Bearish Options Activity Signals Caution in Semiconductor Sector

Key Trading Activity:

Significant bearish positioning emerged in the semiconductor sector Friday, with notable options trades in Micron (MU), Nvidia (NVDA), and the VanEck Semiconductor ETF (SMH) suggesting investor concern about chip stocks.

Major Trades:

• SMH ETF: Over 180,000 put contracts traded versus 50,000 calls by midday, with $46 million in put premium compared to $26 million in calls. Approximately 129,000 puts were purchased, pushing the put-to-call open interest ratio to 1.95—the highest since early August.

• Nvidia: A trader purchased 100,000 put contracts at the $180 strike (expiring January 15) for $21 million, the day's largest options trade. This bearish bet requires NVDA to decline 22% by expiration to profit.

• Micron: The most complex activity occurred here, with approximately $270 million in premium tied to likely put-buying. Deep in-the-money puts with strikes between $2,250-$2,500 expiring June 2028 were purchased, while $2,050 strike puts were sold, creating a net $14.5 million bearish spread position functioning as a synthetic short.

Market Implications:

The Philadelphia Semiconductor Index also saw elevated bearish positioning, with its put-to-call ratio rising to 1.51. Traders appear to be using deep-in-the-money options rather than direct short positions, potentially due to high stock borrowing costs or to limit downside risk. This concentrated options activity suggests institutional investors are hedging or speculating on potential weakness in the semiconductor sector.

Note: Analysts caution that interpreting far out-of-the-money trades with low liquidity can be complex due to dealer pricing dynamics.
