The Zynex, Inc. (NASDAQ:ZYXI) share price has fared very poorly over the last month, falling by a substantial 66%. The recent drop completes a disastrous twelve months for shareholders, who are sitting on a 80% loss during that time.

Although its price has dipped substantially, given close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 17x, you may still consider Zynex as a stock to avoid entirely with its 27.4x P/E ratio. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Zynex hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. If not, then existing shareholders may be extremely nervous about the viability of the share price.

Is There Enough Growth For Zynex?

The only time you'd be truly comfortable seeing a P/E as steep as Zynex's is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 66% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 79% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

The Bottom Line On Zynex's P/E

A significant share price dive has done very little to deflate Zynex's very lofty P/E. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.
