Pre-open Signal Results: 3 Hits and 1 Miss

RMi collects, curates, interprets and disseminates cell and gene therapy sector (C&GT) fact-based news, trusted and verified intel and share pricing data to bridge the gap to an investment decision

Never leave a retail investor uninformed!  It’s not always time to buy or sell; but it is time to KNOW and why! I chose to speak-up when many analysts have shut-up!


 

Looking forward to 2026, investors are likely to focus on whether these high-performing biotech stocks can sustain their momentum through clinical execution, regulatory milestones, commercialization progress, and potential strategic transactions.

 

News: Ultragenyx Pharmaceutical (RARE -$14.47 or -42.32% to $19.72) stock plunged in huge volume and trading; and was temporarily halted Monday morning. Results from P3 studies on its monoclonal antibody named setrusumab did NOT achieve statistical significance against the primary endpoints for reduction in fracture rate. Setrusumab is being tested as a treatment for osteogenesis imperfecta, a disease-causing brittle bone.

The Bottom Line: More of the … WHYs

  • Stuck in the red zone while trimming share pricings
  • Volume was higher on the Nasdaq and considerably higher on the NYSE compared with Friday. On the Nasdaq, falling stocks topped rising issues 5-to-2. On the NYSE, losers edged out winners by nearly 2-to-1.
  • Followed by the 10-year Treasury yield shedding 2 basis points to 4.11%

As I had also written, cash is king for investors who want to keep some liquidity and avoid having to sell in a down market,

  • I would be following share pricing’s ascension on current biotech, cell and gene therapy sector upsides; so, some profiteering can be “situated” while maintaining a position, less elevated!

Most C&GT sector equities dramatically dived on Monday ... 

 

Re Capricor Therapeutics (CAPR +$0.07 after Friday’s -$0.27 after Wednesday’s -$0.57) …  I am STICKING to my CONVICTION that CAPR is overbought and whose valuation is disconnected from fundamentals.

  • Doubts still abound re: regulatory fragility and marginal HOPE-3 results and valuation concerns remain a key hang-up!
  • CAPR remains a structurally challenged, chronically unprofitable company whose valuation is disconnected from fundamentals.
  • It has begun; timing will be everything!
  • The higher CAPR rises, the steeper the fall!
  • Is the RISK woth it ...??

Take it a session at a time … the REAL question is … how long will this sentiment and conviction “run” last in the “clean-out-the-exposure” December?

 

5th and last week of December, Q4 and FY25

  • Monday closed negative with 12 positive, 24 negative and 4 flats

4th week of December:

  • Friday closed negative with 11 positive, 28 negative and 1 flat
  • Thursday was a holiday
  • Wednesday closed positive with 31 positive, 5 negative and 4 flats - not published
  • Tuesday closed negative with 14 positive, 24 negative and 2 flats
  • Monday closed positive with 30 positive, 8 negative and 2 flats

 

As the leading voice of cell and gene therapy investors; I am NOT always a doom and gloom analyst/journalist but a man who has been “there” (BUY, SELL, VC and multiple operating roles) with the gray hair and a readership following with real numbers to prove it!

Welcome to my world of defining the “grey’ in our universe!

  • I hate to be so negative or contrarian but, this is a NO spin zone and facts and truth are its products; I can always be WRONG but, I am mostly EARLY!
  • if I wanted to be liked, I wouldn’t have been an analyst/journalist.
