Key Discoveries

Discovery Implication
CRSP +11.5% week to new 52wk high Gene editing breakout — momentum continuation or blow-off?
MRNA RSI 69→87 in 4 days Still accelerating — what is the catalyst?
ALNY quietly recovered RSI 28→48 Oversold condition resolved without fanfare
LEGN RSI 31→8 reversal Extreme lows repeating — structural issue vs oversold

Mistakes (Don't Repeat)

Mistake Lesson
LEGN bounced RSI 8→31, now back at 8 Without catalyst, extreme oversold means structural problem

Open Questions

  • MRNA: what is driving RSI 69→87 surge over multiple weeks?
  • CRSP new 52wk high — gene editing catalyst or sector rotation?
  • LEGN back at RSI 8 — is $17 the bottom or going lower?
  • ALNY RSI 48 — base building or dead bounce?
