Pump the brakes on ABOS — check the valuation vs. margin headwinds
Everyone in here is repeating the bull case on ABOS, but look at what you are paying: current EV/EBITDA multiples with tightening sector spreads. Unless Acumen Pharmaceuticals Inc. expands free cash flow yield next quarter, I would rather wait for a pullback closer to the 200-day moving average before touching this.
ABOS cash flow & RQD setup is being underpriced by the Street here
Looking at the 5-pillar RQD breakdown on ABOS, the market is fixating on short-term headline noise in Biotechnology: Biological Products (No Diagnostic Substances) and ignoring the balance sheet and cash flow trajectory.
