MU – Multi-Million Dollar Put Buying Hits as Data Center Trade Unwinds

The data-center unwind accelerated today, and Micron (MU) finally cracked with the rest of the AI-hardware names.

NVO – Oversold Setup Showing Signs of Bottoming Amid Healthcare Rebound

After months of steady decline, NVO appears to be stabilizing just as the broader healthcare sector — led by a surge in Eli Lilly (LLY) — is regaining momentum. The sector rotation back into large-cap pharma and biotech has been strong over the past few weeks, and NVO could be positioned to benefit from that […]

MRK – Technical Breakout Watch After Major Long-Term Call Buying

AMZN – Quick Update: Locked In Profits After Strong Run

Amazon ripped higher right out of the gate this morning along with the broader tech sector, following last week’s heavy call buying that I covered in my AMZN Call Buyers Step In post. The 15-minute chart shows a clean breakout from the $245 consolidation zone, tagging the $250 level on strong volume. I sold my […]

WDC — Deep ITM Call Buying Ahead of Earnings

Western Digital (WDC) has been one of the stronger names in the storage and semiconductor space this quarter, riding the AI-driven demand for high-capacity memory and data infrastructure. The company reports earnings this Thursday, and traders seem to be positioning early — but not with speculative short-term calls. On 10/28/25, we saw a wave of […]

NBIS — Long-Dated Bullish Flow Ahead of Fed Day

NBIS has been one of the lesser-known names riding the AI infrastructure wave. The company focuses on advanced computing systems and network technologies that support AI scaling — the kind of behind-the-scenes hardware that makes big AI models actually run. While stocks like NVDA and SMCI dominate headlines, it’s the second-tier players like NBIS that […]

HUN — Heavy Call Buying Raises Eyebrows

Huntsman Corp (HUN) isn’t exactly the kind of name that usually lights up the options tape. It’s an old-line chemicals company — steady, cyclical, and not often the focus of aggressive speculation. That’s why today’s flow stood out. Seeing repeated large call buys in a stock like this usually means something’s up, or someone’s positioning […]
