Eos Energy Enterprises (NASDAQ: EOSE) stock has had a rough start to the year. Shares are 63% off a January high and have plunged 42% year to date. Much of that drop came after the maker of energy storage batteries reported Q4 results late last month.

Eos stock is jumping today, though. As of 1:51 p.m. ET, shares were up by 9.9%.

Insider buying

Eos Energy stock crashed after the company failed to meet its own 2025 revenue projections. Full-year revenue soared 632% compared to 2024, but even that $114.2 million in sales was very disappointing. That's because the company had told investors to expect full-year revenue of between $150 million and $160 million as recently as November. Additionally, projections for 2026 revenue of $300 million-$400 million also fell short of market expectations.

Eos Energy offers battery storage systems for large-scale energy storage applications across grid-scale, utility, commercial, and industrial sectors. It serves utility providers, renewable energy developers, and commercial and industrial clients seeking comprehensive energy storage solutions.

Renewable energy stocks generally have a good following among retail investors. A survey found that over 60% of investors already own renewable energy stocks or funds, and 90% plan to own them, according to recent research from The Motley Fool.

Despite its disappointing results and perhaps because of the stock's decline, Eos Energy CEO Joe Mastrangelo and director Alex Dimitrief both just added shares. Mastrangelo spent $345,000 for 60,000 shares of the common stock on March 2, and Dimitrief bought 15,000 shares on the same day.

Investors like insider buying and the vote of confidence it conveys. That explains why shares of Eos Energy Enterprises popped today.

Bitcoin briefly loses 2025 gains as crypto plunges over the weekend.Bitcoin experienced a sharp decline this weekend, briefly erasing its 2025 gains and dipping below its year-opening value of $93,507. The cryptocurrency fell to a low of $93,029 on Sunday, representing a 25% drop from its all-time high in October. Although it has rebounded slightly to around $94,209, the pressures on the market remain significant. The downturn occurred despite the reopening of the U.S. government on Thursday, which many had hoped would provide essential support for crypto markets. This year initially appeared promising for cryptocurrencies, particularly after the inauguration of President Donald Trump, who has established the most pro-crypto administration thus far. However, ongoing political tensions—including Trump's tariff strategies and the recent government shutdown, lasting a historic 43 days—have contributed to several rapid price pullbacks for Bitcoin throughout the year. Market dynamics are also being influenced by Bitcoin whales—investors holding large amounts of Bitcoin—who have been offloading portions of their assets, consequently stalling price rallies even as positive regulatory developments emerge. Despite these sell-offs, analysts from Glassnode argue that this behavior aligns with typical patterns seen among long-term investors during the concluding stages of bull markets, suggesting it is not indicative of a mass exodus. Notably, Bitcoin is not alone in its struggles, as Ethereum and Solana have also recorded declines of 7.95% and 28.3%, respectively, since the start of the year, while numerous altcoins have faced even steeper losses. Looking ahead, questions linger regarding the viability of the four-year cycle thesis, particularly given the increasing institutional support and regulatory frameworks now in place in the crypto landscape. Matt Hougan, chief investment officer at Bitwise, remains optimistic, suggesting a potential Bitcoin resurgence in 2026 driven by the “debasement trade” thesis and a broader trend toward increased adoption of stablecoins, tokenization, and decentralized finance. Hougan emphasized the soundness of the underlying fundamentals, pointing to a positive outlook for the sector in the longer term.
