So what

We can attribute Insulet stock's robust performance last month to the company's Nov. 5 release of its third-quarter results, which were better than Wall Street and many investors were expecting, and to management once again raising its full-year 2019 revenue guidance. Shares popped 10.5% on the day following the release and continued to climb higher throughout the month.

In Q3, Insulet's revenue soared 27% year over year to $192.1 million, easily topping the $179.5 million Wall Street expectation. Adjusted earnings per share (EPS) tripled to $0.09, crushing the analyst consensus estimate of $0.03. 

Now what

For the fourth quarter, Insulet guided for revenue growth of about 17% to 22% year over year. And for full-year 2019, it expects revenue to increase about 28% to 29%, up from its previous outlook of 24% to 27% growth. The company doesn't provide earnings guidance.
