Congratulations to $DAWN for being the worst performing commercial-stage oncology focused bio stock in the peer group since 11/12/25 (day before announcing the $MRSN acquisition). DAWN is off 23% while the $XBI is up 8%. Investors have spoken Because 95-98% of new cancer drugs in Phase 1 trials are never approved (& why most oncology bios fail), valuations of clinical-stage oncology stocks have plummeted since the XBI peaked 2/21. DAWN was clever enough to IPO in 5/21 when the XBI was still trading in the 130s. Investors were warned @ JP Morgan last January when DAWN CEO Mr. Bender said, instead of exiting via M&A, he promised to focus on building a business with a 95-98% failure rate. Mr. Bender went to Ivy League universities so he probably has a much higher IQ than most. Of the 100s of new oncology focused bios since 1/1/13, only 2 have scored 2 drug approvals with large TAMs ($SNDX & SWTX $URGN has 2 drugs but the same API). Perhaps DAWN wins w/DAY-301 & MRSN.

$SGBX I already warned you yesterday, a sharp rise was very likely. $CHRS next Monster runner?🚨 This share is highly undervalued and has a high probability of being acquired. Its cash (194 millions) reserves exceed its market cap (155 millions) This November, Day One Biopharmaceuticals acquired Mersana Therapeutics ($MRSN), Merk ($MERK.X) acquired Cidara Therapeutics ($CDTX),..... The sector is on fire 🔥🔥🚀 ¿December? ¿BOOM?🔥💯

$MRSN 📈 How a stock can still go higher Even when it looks “topped out,” a stock can continue if: Volume remains heavy No major sellers appear There’s a fresh catalyst It forms higher lows Market sentiment stays risk-on Your chart (MRSN) has: A huge run Small consolidation near highs No major sell-off yet Momentum indicators still above centerlines This does leave room for continuation — but with big volatility risk.Do your Own Due Diligence & Homework!
