Frequently asked questions

Is ASMB overvalued?

ASMB scores 37/100 on our Smart Value Score (Grade D), a weak overall profile. The DCF also shows a positive margin of safety, so price and fundamentals line up reasonably well.

What is ASMB's fair value?

Our DCF model estimates ASMB's intrinsic value at $40.62 per share, versus the current price of $20.86, a margin of safety of +32.64%. Fair value is the present value of the cash flows we project the business to produce, so a price below it means the market is pricing the stock below that conservative estimate.

What P/E ratio does ASMB trade at?

ASMB trades at a P/E of 19.3x on trailing twelve-month earnings, against a 5-year median of 22.8x. P/E is what you pay per dollar of profit, and sitting below its own median means the stock is cheaper than usual relative to its earnings.

Is ASMB a buy based on valuation?

Our Smart Value rating for ASMB is Sell, from a Smart Value Score of 37/100 that blends growth, quality, and valuation. The profile skews cautious, and a better price or clearer operating improvement would strengthen the case. This is research to inform your decision, not personalized financial advice.

How does ASMB's valuation compare to its history?

On P/E, ASMB sits in the 17th percentile of its own 5Y range, historically cheap relative to where it has traded. A low percentile means today's multiple is near the bottom of its historical band.

What is ASMB's Smart Value Score?
