JinkoSolar (NYSE: JKS), a leading solar panel manufacturer, saw its stock soar 7.03% in pre-market trading on Sunday, as investors eagerly await the company's quarterly earnings report scheduled for Monday. This significant uptick continues the stock's recent positive momentum, with shares having already climbed 17% over the past month and 16.6% in the last quarter.

The pre-earnings rally suggests growing optimism among investors about JinkoSolar's financial performance. Market analysts are particularly focused on the company's progress in high-power products, especially its third-generation TOPCon solar panels, which are expected to boost revenues through premium pricing and market share gains. Additionally, JinkoSolar's expanding energy storage systems (ESS) business, with its strategic focus on overseas markets, is anticipated to be a key growth driver.

Adding to the pre-earnings excitement is a growing narrative that JinkoSolar may be significantly undervalued. Some market observers peg the company's fair value at $37.42 per share, representing a substantial premium to its recent closing price of $27.04. This perceived gap between market price and intrinsic value could be fueling additional investor interest. However, investors should remain cautious, as ongoing trade policy changes and declining U.S. shipments pose potential risks to the company's profitability outlook. As the market awaits Monday's earnings announcement, all eyes will be on JinkoSolar to see if it can justify the recent stock surge and optimistic valuation estimates.
