Listen to the news

Moderna (MRNA) moved back into focus after its shares closed at US$146.69, rising 1.89% on a day when major indexes fell, ahead of an earnings report expected to show weaker EPS and revenue.

Over the past month, Moderna has delivered a 30 day share price return of 127.05%, contributing to a year to date share price gain of 365.88% and a one year total shareholder return of 478.78%. However, the five year total shareholder return is down 66.88%, which shows very strong recent momentum coming off a weak longer term base as investors reassess both growth prospects and risk ahead of the earnings update.

Most Popular Narrative: 225% Overvalued

At a last close of $143.77 against a narrative fair value of $44.25, Moderna screens as heavily priced, with that gap hinging on how the mRNA pipeline and flu progress translate into real earnings power over time.

The dramatic expansion and advancement of Moderna's mRNA pipeline beyond COVID-19, including recent positive late-stage data and upcoming filings for flu, RSV, CMV, oncology, and rare diseases, are likely to diversify the revenue base, capitalize on the rising global burden of infectious and chronic diseases, and materially boost future top-line growth.

See why 215 investors see Moderna as 225% overvalued.

Result: Fair Value of $44.25 (OVERVALUED)

Still, the story can change quickly if COVID vaccine demand keeps fading or flu uptake lags the projections that analysts are using to justify Moderna’s current valuation.
