AMC Entertainment Holdings' stock fell on Monday, extending a prolonged losing streak as investors largely ignored the theater chain's announcement of its strongest pre-Christmas weekend box office in four years. With AMC disclosing amended terms for its debt securities—including potential additional common stock sales in the open market—investors appeared to shift focus to the company's financial challenges.

AMC shares closed down 2.9% at $1.70. For the former meme-stock darling, this marked not only its 10th consecutive daily decline (the longest streak since an 11-day drop ending January 27, 2022) but also a sixth straight record-low closing price.

The selloff continued despite the company reporting its best pre-holiday weekend performance since 2021 based on theater attendance and ticket revenue. The strong showing was primarily driven by Walt Disney Company's "Avatar: Fire and Ash," which grossed $88 million domestically over the weekend—ranking as the seventh-highest December opening weekend in box office history, according to Box Office Mojo.
