Why Healthcare Investors Shouldn’t Bank on Drug Pipelines

Healthcare stocks can conjure up images of clinical trials, blockbuster drugs and supersized marketing campaigns. But that’s a one-dimensional way of viewing a fast-growing, dynamic sector—and a risky way to invest. For investors looking to avoid the roller-coaster ride, we recommend a different approach: evaluating companies based on their business acumen—not their drug pipeline.

High-profile drug breakthroughs get a lot of attention, and for good reason. At the height of the pandemic, the race was on for a COVID-19 vaccine that could save lives and hasten a return to normalcy. How about a drug that can treat Type 2 diabetes and help you lose weight? There’s a reason GLP-1 drugs are so popular. And who doesn’t want to invest in the cure for cancer, Alzheimer’s and any number of other devastating illnesses?

It's a Long Road from Phase I to the Finish Line

Unfortunately for investors, it’s notoriously difficult to handicap outcomes as a drug passes through the various stages of the development pipeline. In fact, the likelihood that a drug in human trials will complete the journey from Phase I to final approval by the Food and Drug Administration (FDA) is a mere 10% (Display). Put another way, the failure rate for developing a drug is 90%, a figure that doesn’t include the extensive pretrial process that can stop a drug from moving into Phase I. That’s a challenging investment proposition, to say the least.

A case in point: In November 2020, when Pfizer and Moderna first announced their breakthrough COVID-19 vaccines, there were 236 COVID-19 vaccines in various stages of development. Only three were given FDA approval for use in the United States. More than 90% of the vaccines under development failed to get the FDA’s blessing.
