Investors should treat insider transactions with some nuance. After all, insiders sell shares for a variety of reasons, ranging from tax purposes to estate planning. In any event, outside investors should consider a company’s fundamentals before deciding to buy or sell shares. With that in mind, let’s take a closer look at Guardant Health.
For starters, Guardant Health stock has traveled an interesting path over the last five years. Overall, the stock has delivered a total return of 59%, equating to a quite respectable compound annual growth rate (CAGR) of 9.7%. However, much of those gains have come in the last 12 months alone, where the stock has surged by an impressive 201%. Still, over the last five years, the stock has underperformed the S&P 500, which generated a total return of 86%, with a CAGR of 13.2%.
Recent earnings results help explain the stock’s 12-month surge. Revenue in the second quarter jumped 44% on a year-over-year basis. Meanwhile, management raised full-year revenue guidance. Granted, the company posted a net loss, but that is not uncommon for a biotech company like Guardant. The real test comes in the company’s ability to manage its path to profitability, and on that front, its increasing revenue should help the company hit its target of positive free cash flow by the end of 2027.
In summary, growth investors seeking exposure to a biotech stock may want to consider Guardant. The company’s recent results demonstrate that it is performing well. However, value-oriented investors will need to look elsewhere, given the company’s lack of profits.
