Buy or Sell Plug Power Stock Ahead of Its Upcoming Earnings?

Plug Power (NASDAQ: PLUG), a hydrogen fuel cell company, is scheduled to release its earnings on Monday, August 11, 2025. Based on historical data, the stock has a higher chance of a negative one-day reaction. Over the past five years, PLUG has experienced a one-day decline following earnings in 61% of instances, with a median loss of -5.9% and a maximum one-day drop of -40.5%. This highlights the stock’s significant volatility around its earnings reports.

For event-driven traders, understanding these historical patterns can provide an edge, although the actual results versus consensus expectations will be the primary driver. There are two potential strategies to consider:

• Pre-Earnings Positioning: Analyze the historical probabilities and take a position before the earnings report is public.
• Post-Earnings Positioning: Examine the correlation between immediate and medium-term returns after the announcement to guide your decisions.

Consensus estimates project a notable improvement in the company’s performance for this quarter. Analysts expect revenue to be $158 million and an adjusted loss of $0.16 per share, which compares favorably to the previous year’s quarter, where revenue was $143 million and the adjusted loss was $0.34 per share.

From a fundamental perspective, the company has a current market capitalization of $1.4 billion. Over the last twelve months, Plug Power generated $642 million in revenue but was operationally loss-making, with operating losses of -$988 million and a net loss of -$2.0 billion.

That said, if you seek upside with lower volatility than individual stocks, the Trefis High Quality portfolio presents an alternative — having outperformed the S&P 500 and generated returns exceeding 91% since its inception. Separately, see – What’s Happening With JOBY Stock?

Correlation Between 1D, 5D, and 21D Historical Returns

A relatively less risky strategy (though not useful if the correlation is low) is to understand the correlation between short-term and medium-term returns post earnings, find a pair that has the highest correlation, and execute the appropriate trade. For example, if 1D and 5D show the highest correlation, a trader can position themselves “long” for the next 5 days if the 1D post-earnings return is positive. Here is some correlation data based on a 5-year and a 3-year (more recent) history. Note that the correlation 1D_5D refers to the correlation between 1D post-earnings returns and subsequent 5D returns. Also, see – Buy or Sell PLUG Stock?
