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 +2.9%, compared to the Zacks S&P 500 composite's +1.1% change. During this period, the Zacks Manufacturing - Electronics industry, which Plug Power falls in, has gained 3.1%. 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

Rather than focusing on anything else, we at Zacks prioritize evaluating the change in a company's earnings projection. This is because we believe the fair value for its stock is determined by the present value of its future stream of earnings.

Our analysis is essentially based on how sell-side analysts covering the stock are revising their earnings estimates to take the latest business trends into account. When earnings estimates for a company go up, the fair value for its stock goes up as well. And when a stock's fair value is higher than its current market price, investors tend to buy the stock, resulting in its price moving upward. Because of this, empirical studies indicate a strong correlation between trends in earnings estimate revisions and short-term stock price movements.

For the current quarter, Plug Power is expected to post a loss of $0.26 per share, indicating a change of +13.3% from the year-ago quarter. The Zacks Consensus Estimate has changed -13.9% over the last 30 days.

For the current fiscal year, the consensus earnings estimate of -$0.89 points to a change of +28.8% from the prior year. Over the last 30 days, this estimate has changed -15%.

For the next fiscal year, the consensus earnings estimate of -$0.30 indicates a change of +66.7% from what Plug Power is expected to report a year ago. Over the past month, the estimate has changed +53.5%.

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.

For Plug Power, the consensus sales estimate for the current quarter of $251.5 million indicates a year-over-year change of +66.3%. For the current and next fiscal years, $1.31 billion and $2.02 billion estimates indicate +86.9% and +54.2% changes, respectively.

Plug Power reported revenues of $210.29 million in the last reported quarter, representing a year-over-year change of +49.4%. EPS of -$0.35 for the same period compares with -$0.27 a year ago.

Compared to the Zacks Consensus Estimate of $199.73 million, the reported revenues represent a surprise of +5.29%. The EPS surprise was -29.63%.

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


Without considering a stock's valuation, no investment decision can be efficient. In predicting a stock's future price performance, it's crucial to determine whether its current price correctly reflects the intrinsic value of the underlying business and the company's growth prospects.

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

As part of the Zacks Style Scores system, the Zacks Value Style Score (which evaluates both traditional and unconventional valuation metrics) organizes stocks into five groups ranging from A to F (A is better than B; B is better than C; and so on), making it 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.
