Plug Power (PLUG - Free Report) is one of the stocks most watched by visitors lately. So, it might be a good idea to review some of the factors that might affect the near-term performance of the stock.

Over the past month, shares of this alternative energy company have returned -23.9%, compared to the Zacks S&P 500 composite's -9.7% change. During this period, the Zacks Manufacturing - Electronics industry, which Plug Power falls in, has lost 10.9%. The key question now is: What could be the stock's future direction?

Although media reports or rumors about a significant change in a company's business prospects usually cause its stock to trend and lead to an immediate price change, there are always certain fundamental factors that ultimately drive the buy-and-hold decision.

Revisions to Earnings Estimates

Here at Zacks, we prioritize appraising the change in the projection of a company's future earnings over anything else. That's because we believe the present value of its future stream of earnings is what determines the fair value for its stock.

We essentially look at how sell-side analysts covering the stock are revising their earnings estimates to reflect the impact of the latest business trends. And if earnings estimates go up for a company, the fair value for its stock goes up. A higher fair value than the current market price drives investors' interest in buying the stock, leading to its price moving higher. This is why empirical research shows a strong correlation between trends in earnings estimate revisions and near-term stock price movements.

Plug Power is expected to post a loss of $0.22 per share for the current quarter, representing a year-over-year change of -15.8%. Over the last 30 days, the Zacks Consensus Estimate has changed -1.2%.

The consensus earnings estimate of -$0.96 for the current fiscal year indicates a year-over-year change of -20%. This estimate has changed +0.2% over the last 30 days.

For the next fiscal year, the consensus earnings estimate of -$0.46 indicates a change of +51.2% from what Plug Power is expected to report a year ago. Over the past month, the estimate has changed +9.4%.

With an impressive externally audited track record, our proprietary stock rating tool -- the Zacks Rank -- is a more conclusive indicator of a stock's near-term price performance, as it effectively harnesses the power of earnings estimate revisions. The size of the recent change in the consensus estimate, along with three other factors related to earnings estimates, has resulted in a Zacks Rank #3 (Hold) for Plug Power.

Revenue Growth Forecast

While earnings growth is arguably the most superior indicator of a company's financial health, nothing happens as such if a business isn't able to grow its revenues. After all, it's nearly impossible for a company to increase its earnings for an extended period without increasing its revenues. So, it's important to know a company's potential revenue growth.

In the case of Plug Power, the consensus sales estimate of $265.85 million for the current quarter points to a year-over-year change of +84.7%. The $910.96 million and $1.47 billion estimates for the current and next fiscal years indicate changes of +81.3% and +61.1%, respectively.

Last Reported Results and Surprise History

Plug Power reported revenues of $151.27 million in the last reported quarter, representing a year-over-year change of +21.4%. EPS of -$0.30 for the same period compares with -$0.18 a year ago.

Compared to the Zacks Consensus Estimate of $169.06 million, the reported revenues represent a surprise of -10.53%. The EPS surprise was -42.86%.

The company could not beat consensus EPS estimates in any of the last four quarters. The company topped consensus revenue estimates two times over this period.


No investment decision can be efficient without considering a stock's valuation. Whether a stock's current price rightly reflects the intrinsic value of the underlying business and the company's growth prospects is an essential determinant of its future price performance.

While comparing the current values of a company's valuation multiples, such as price-to-earnings (P/E), price-to-sales (P/S) and price-to-cash flow (P/CF), with its own historical values helps determine whether its stock is fairly valued, overvalued, or undervalued, comparing the company relative to its peers on these parameters gives a good sense of the reasonability of the stock's price.

The Zacks Value Style Score (part of the Zacks Style Scores system), which pays close attention to both traditional and unconventional valuation metrics to grade stocks from A to F (an An is better than a B; a B is better than a C; and so on), is pretty helpful in identifying whether a stock is overvalued, rightly valued, or temporarily undervalued.

Plug Power is graded F on this front, indicating that it is trading at a premium to its peers. Click here to see the values of some of the valuation metrics that have driven this grade.
