Despite an already strong run, Sezzle Inc. (NASDAQ:SEZL) shares have been powering on, with a gain of 28% in the last thirty days. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

In spite of the firm bounce in price, Sezzle's price-to-sales (or "P/S") ratio of 1.2x might still make it look like a buy right now compared to the Diversified Financial industry in the United States, where around half of the companies have P/S ratios above 2.4x and even P/S above 5x are quite common. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

How Sezzle Has Been Performing

With revenue growth that's inferior to most other companies of late, Sezzle has been relatively sluggish. The P/S ratio is probably low because investors think this lacklustre revenue performance isn't going to get any better. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

Is There Any Revenue Growth Forecasted For Sezzle?

The only time you'd be truly comfortable seeing a P/S as low as Sezzle's is when the company's growth is on track to lag the industry.

Taking a look back first, we see that the company grew revenue by an impressive 24% last year. The latest three year period has also seen an excellent 250% overall rise in revenue, aided by its short-term performance. So we can start by confirming that the company has done a great job of growing revenue over that time.

Shifting to the future, estimates from the two analysts covering the company suggest revenue growth is heading into negative territory, declining 4.0% per annum over the next three years. Meanwhile, the broader industry is forecast to expand by 9.4% each year, which paints a poor picture.

With this information, we are not surprised that Sezzle is trading at a P/S lower than the industry. However, shrinking revenues are unlikely to lead to a stable P/S over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

The Final Word

Sezzle's stock price has surged recently, but its but its P/S still remains modest. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

It's clear to see that Sezzle maintains its low P/S on the weakness of its forecast for sliding revenue, as expected. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. Unless there's material change, it's hard to envision a situation where the stock price will rise drastically.
