Krispy Kreme's stock price surged over 26% during trading and continued to rise 24% after hours, despite no company-specific news. The increase was driven by social media buzz and retail investor momentum, particularly among meme stock traders. Trading volume soared to over 37 million shares, far above the average. With a significant short interest of over 26%, the stock became a prime candidate for a short squeeze. The recent movement follows trends seen in other heavily shorted stocks, highlighting the power of meme-driven investing.
