There's Reason For Concern Over Diagnósticos da América S.A.'s (BVMF:DASA3) Massive 68% Price Jump

Simply Wall St · 2d ago

Despite an already strong run, Diagnósticos da América S.A. (BVMF:DASA3) shares have been powering on, with a gain of 68% in the last thirty days. The last 30 days bring the annual gain to a very sharp 73%.

Even after such a large jump in price, it's still not a stretch to say that Diagnósticos da América's price-to-sales (or "P/S") ratio of 0.3x right now seems quite "middle-of-the-road" compared to the Healthcare industry in Brazil, where the median P/S ratio is around 0.4x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

Is There Some Revenue Growth Forecasted For Diagnósticos da América?

There's an inherent assumption that a company should be matching the industry for P/S ratios like Diagnósticos da América's to be considered reasonable.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 16%. Unfortunately, that's brought it right back to where it started three years ago with revenue growth being virtually non-existent overall during that time. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Looking ahead now, revenue is anticipated to slump, contracting by 17% during the coming year according to the lone analyst following the company. Meanwhile, the broader industry is forecast to expand by 10%, which paints a poor picture.

In light of this, it's somewhat alarming that Diagnósticos da América's P/S sits in line with the majority of other companies. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as these declining revenues are likely to weigh on the share price eventually.
