10 Stocks Already Hurting in December

8. Sunrun Inc. (NASDAQ:RUN)

Sunrun fell by 8.40 percent on Monday to close at $18.55 apiece as investors resorted to profit-taking following five straight days of gains, while unloading positions ahead of the looming deadline for tax credits on clean energy investments.

At present, solar customers are enjoying as much as 30 percent tax credits from the government, a subsidy which will expire on December 31, 2025 as stated under the provisions of the One Big Beautiful Bill Act which President Donald Trump signed into law in July this year.

Analysts have earlier projected that the looming deadline could prop up solar companies’ earnings performance in the second half of 2025 on expectations that customers would scramble to get installations completed prior to the deadline. Thereafter, earnings are expected to dwindle as solar installations decline.

In other developments, sentiment for Sunrun Inc. (NASDAQ:RUN) was further dampened by earlier reports that one of its solar peers—PosiGen, officially filed for bankruptcy following the Trump administration’s cuts to solar tax credits.

Sunrun Inc. (NASDAQ:RUN) is one of the largest solar companies in the US. In the third quarter of the year, the company swung to a net income attributable to shareholders of $16.6 million from an attributable net loss of $83.77 million. Revenues grew by 34.8 percent to $724 million from $537 million year-on-year, propped up by higher solar energy systems and product sales.
