Should l Buy MASI?
Source: Coinmarketcap
Masimo Corp. shares surged by 34.08% in pre-market trading, crossing above the 5-day SMA, as investors reacted positively to reports of a potential acquisition by Danaher.
The significant increase in Masimo's stock price is attributed to news that Danaher is nearing a $9.9 billion acquisition deal, which represents a notable premium over Masimo's market capitalization. This acquisition is expected to enhance Masimo's market position in the medical technology sector, especially following recent organizational realignments aimed at focusing on core healthcare offerings. Additionally, a U.S. jury's ruling ordering Apple to pay Masimo $634 million for patent infringement could further improve the company's financial outlook.
This acquisition news has generated optimism among investors, reflecting a strong belief in Masimo's growth potential within the medical device market. The anticipated deal could mark a significant shift for Masimo, positioning it for future success under new leadership.

Exiting Danaher Position with 7% Loss
- Position Reduction: We sold 200 shares of Danaher at approximately $208 each on Thursday, resulting in a disappointing 7% loss on shares purchased between 2023 and 2025, reflecting our disillusionment with the company's future performance.
- Weak Growth: Despite our hopes for Danaher's bioprocessing business to recover post-COVID, its revenue growth has failed to achieve consistent high single-digit percentages, prompting us to clean up our portfolio to free up space for new opportunities.
- Lack of Confidence in Acquisitions: Our confidence in Danaher's recent acquisition strategy has waned, particularly as the acquisitions of Abcam and Aldevron did not drive performance as expected, deepening our pessimism regarding their acquisition of Masimo.
- Legal Risk Consideration: Given the longstanding legal battle between Apple and Masimo, which could pose additional risks for Danaher in the future, we are more inclined to seek alternative investment opportunities.
