Glance View

Masimo Corp., a pioneering force in noninvasive monitoring technologies, was founded in 1989 by Joe Kiani, who envisioned a healthcare landscape imbued with precision and accessibility. The company rose to prominence with its innovative pulse oximetry technology, a tool crucial for measuring oxygen levels in patients' blood. Unlike traditional methods, Masimo's technology utilizes proprietary signal extraction techniques that allow it to deliver accurate readings even in challenging conditions such as movement or low perfusion. This innovation not only revolutionized patient monitoring but also secured Masimo significant market share within hospitals and healthcare facilities worldwide. Their devices, known for their reliability, feed into a recurring revenue model, as hospitals and medical professionals constantly require new sensors and related consumables to operate the equipment effectively. In addition to pulse oximetry, Masimo has skillfully expanded its portfolio to encompass advanced monitoring systems such as those measuring brain function and hydration levels, offering a comprehensive suite of solutions for enhanced patient care. They have ventured into consumer health as well, with devices that allow people to monitor their health metrics at home. This broadening of scope positions Masimo as a versatile player across both professional and consumer markets. By continually investing in research and development, Masimo aims to address unmet clinical needs and open new revenue streams, thus sustaining its growth trajectory in the competitive landscape of medical technology. Through strategic partnerships and acquisitions, the company has consistently augmented its capabilities, solidifying a robust financial performance anchored in its commitment to innovation and quality.

What is Insider Trading?

Insider trading refers to the buying or selling of a company’s stock by individuals with access to non-public, material information about the company.

While legal insider trading occurs when insiders follow disclosure rules, illegal insider trading involves trading based on confidential information and is prohibited by law.

Why is Insider Trading Important?

It isn't a coincidence that corporate executives seem to always buy at the right times. After all, they have access to every bit of company information you could ever want.

However, the fact that company executives have unique insights doesn't mean that individual investors are always left in the dark. Insider trading data is out there for all who want to use it.

Peter Lynch

Insiders might sell their shares for any number of reasons, but they buy them for only one: they think the price will rise.
