GeneDx's proposed Medicare cuts may have a much smaller direct impact than its selloff implies. Craig-Hallum estimates a $5.6 million annual hit, about 1% of exome and genome revenue. Q2 testing volume grew 32%, though revenue per test is declining; the proprietary rare-disease database and potential for AI-driven interpretation remain compelling. At $65, risk/reward might be attractive again, but reimbursement, profitability and execution remain risks. November 3 earnings should clarify. x.com 

AI now makes early disease detection possible at scale, and catching disease early is always cheaper than treating it late. Detection names like Grail, Guardant, RadNet and Lunit win on distribution and reimbursement; grading names like Tempus, Veracyte, GE HealthCare and HeartFlow build data moats near treatment decisions. Monitoring via Natera, Personalis and iRhythm is the most asymmetric layer, a recurring subscription. NVIDIA gets paid whichever test wins. x.com 

BillionToOne is taking share in both prenatal testing and oncology thanks to patented technology that makes its tests more sensitive and specific. It is the only diagnostic peer that is GAAP profitable, and it may be best positioned to offer a genuinely useful early cancer detection test, adding optionality. On revenue it looks pricier, but its real comparables, Natera and Guardant Health, are about 50% more expensive while growing more slowly and earning less. x.com  x.com 

Tempus AI's diagnostics-to-data-to-AI flywheel makes its roughly 7.2x forward sales interesting, about half Natera's and Guardant's 16x, though both grow faster. Q2 revenue rose 22% to $382.5M, Data Licensing & Modeling grew 36%, and 2026 guidance is about $1.6B of revenue and $65M of adjusted EBITDA. As a ~25% growth diagnostics company, ~7x may be reasonable; if growth reaccelerates toward 30%+, Data + Applications grows much larger and margins expand, the valuation could look very different. … Show more

Tempus AI's growth story has become a real one, with Q2 revenue up 22% to $382.5 million, positive net income and EBITDA, a 73.5% gross margin and $816 million of cash. Its $1.5 billion Personalis deal owns the sequencing technology behind the Moderna-Merck mRNA cancer vaccine, whose strong Phase 3 melanoma results validated the bet. Piper Sandler upgraded it to Overweight with a $76 target, up from $56, citing Personalis and strong INTerpath-001 MRD data. $80 is support for the breakout. x.com 

Summit Therapeutics' leaders bought at the lows, a strong signal ahead of the November 14 FDA decision date for ivonescimab. Co-CEO Robert Duggan bought 3.81M shares twice at $13.12, about $100M, the same week Summit pulled a $500M stock offering, choosing personal cash over dilution. Phase 3 HARMONi-6 showed ivonescimab cut the risk of death 34% versus tislelizumab combinations in first-line squamous NSCLC. A pennant breakout above $15.88 could run toward the $20s. x.com  x.com 

Tempus AI's $1.5 billion all-stock acquisition of Personalis strengthens its position in precision oncology, adding Personalis' MRD platform, expanding its AI-driven diagnostics business and widening its opportunity in a market estimated at about $20 billion. The 6% drop on the news reflects dilution, timing ahead of earnings and near-term integration risk, a classic case of short-term dilution overshadowing long-term strategy. x.com  x.com 

Tempus AI's $1.5B all-stock acquisition of Personalis is smart long-term positioning despite the dilution-driven dip. Owning Personalis's NeXT Personal MRD technology outright lets Tempus pair liquid-biopsy recurrence testing, one of oncology's fastest-growing areas, with its multimodal dataset and AI at scale. That extends Tempus from diagnostics into high-margin longitudinal monitoring and could strengthen its moat, though execution will decide it. x.com
