What is Pulse?

SPAC Pulse measures the current vitality of a deal on a 0–100 scale. A new IPO starts near 50 — a healthy heart with room both ways. It is not weakening just because nothing has printed yet. Weakening is a tag for a slowing beat (stalling cadence), not a quiet shell. 10-Q / 10-K on time is a good beat; an NT is a deficiency. File the report late, then file the NT late, and Pulse falls — that is how public investors read whether management is on top of the shell. Filing recovers some of it. It never pretends the miss did not happen. When other new IPOs file that window on time, they are no longer equal — those shells are healthier. High readings mean the deal book is accelerating; low readings flag life-support risk. Full methodology lives on the desk.
