$MRK saw a big move on the options tape today Around 3:22pm, about 40,000 deep ITM calls traded in seven large blocks for 3/20 expiry That's a ~$102.6M premium, way above existing open interest at the $70 to $90 strikes Price stayed flat, down 0.25% today with no news driving this Feels like complex institutional positioning rather than a clear upside signal Implied vols are high, around 130 to 280% plus, so I'm not jumping in on these calls yet Watching how Monday's open interest shifts and price action around those strikes This one's on the watchlist for now

$GPCR $VKTX structure has data this month. It is tiny 18 pt arm. But it is a bipolar market and clearly doesn’t understand data at first glance. I had big position in structure and I sold after Lilly attain 1. I don’t beleive in the whole small mole anymore. But all obesity biotech been undervalued vs crazy valuations for others. So people could still do well on structure if data show further wt loss. I would not hold it through the summer as high chance $LLY drug will start showing liver toxicity. It looks peptides may still dominate as injections and orally. Even the incompetent $MRK management could ask their MDs and look at liver enzymes issues.

$NKTR folks to give you an idea of the size of the market for REZPEG in 2030 the only Drug that does $30B in sales now is Keytruda. Which accounts for 1/2 of $MRK market cap of $287B Thus in theory if all goes well we could see $130B market cap if it takes over Dupi too.

$MAIA The 2028 patent cliff poses a $170-350B revenue risk for Big Pharma through 2032, with oncology heavyweights like Merck's Keytruda ($30B annual sales) losing U.S. exclusivity, enabling biosimilars and generics to erode markets—driving urgent M&A (e.g., $173B in at-risk sales by 2032) for innovative assets like MAIA Biotechnology ($MAIA) THIO to fill gaps in immuno-oncology pipelines. THIO's differentiated mechanism, high Phase 3 success probability (96-99% Bayesian), and pan-cancer appeal make it a prime partnership/acquisition target for firms like Merck ($MRK), Bristol Myers Squibb ($BMY), or Pfizer ($PFE) seeking post-cliff growth in a $668B oncology market by 2034.

$MRK take a look at $ELTX CEO comment 30’ ago: “Fewer disease progressions and deaths than projected to date have been observed in the ongoing 2:1 randomized Phase 2 AMPLIFY-7P trial” The previous comment by Elicios CEO is key: he is telling you that the results are guaranteed to be good, better than anything currently available. This company could be one of the best investments in the history of biotechnology. It is certainly worth much more than its current valuation. I will Increase my position

$MRNA Moderna’s mRNA 4157 (V940) combined with Keytruda delivered a durable 49% reduction in recurrence or death for Phase 2b melanoma results. Merck’s Keytruda pulled $31.7B in 2025 revenue. Keytruda’s patent clock is ticking and Merck can extend with mRNA-4157. The 49% RFS benefit holding at 5 years is rare in oncology. Most immunotherapy benefits erode over time. This one didn't. The 62% DMFS reduction is actually the stronger number and it's underreported. Follow the bread crumbs that show news coming on large partnership or buyout $JNJ $MRK $ABBV Will J&J, Merck, or AbbVie make the next move on Moderna's platform? Buy Moderna and hold. Then buy some more.

Immuno oncology momentum is real. $BNTX expanding oncology. $MRK pushing deeper into bladder with checkpoint combos. Sector trend is clear: vaccines + checkpoint inhibitors = better durability. $BIOV.CSE $BVAXF advancing MVP S with positive multi cancer data, including 24% ORR in ovarian. Platform leverage in a combo driven market.

Cantor reiterated $CMPX at an Overweight rating, and said: In April, we expect the long-awaited PFS/OS readout from the Phase 2/3 COMPANION-002 trial of tovecimig (DLL4 x VEGF-A) in second-line biliary tract cancer (BTC). $AZN $MRK PFE RLAY Cantor added—This represents a high-stakes readout for Compass and one we view with cautious optimism. In this note, we walk through trial background, expectations for PFS and OS, potential stock scenarios, and key risks. We believe the trial is highly likely to achieve statistical significance on PFS, broadly in line with investor expectations. The core debate centers on overall survival (OS) and whether the study will clear the statistical threshold on this secondary endpoint. Given that ~80% OS events were triggered in 1Q26, in-line with our assumptions in our initiation report, we maintain our ~50% probability of success for OS.

Bought $MRK at $116.18. From Grok: "Recommend LONG on MRK as new AI-oncology partnership with Tempus provides strong bullish catalyst differing from prior weak guidance exit, with oversold Stoch at 12.48, price at BB lower 115.99 near support, and MACD histogram improving from -0.48 to 0.60 despite still bearish, justifying quick re-entry at better 115.99 vs 116.07 exit as breakdown eases in uptrend pullback." https://www.techtrader.ai/grokwall/?post=16879&utm_source=dlvr.it&utm_medium=stocktwits
