The maker of RAIN RFID chips, which helps supply chains frictionlessly track items, has been highly volatile since its July 2016 IPO.

CEO Chris Diorio called the fourth quarter "a strong close to a landmark and transformational year for Impinj" as revenue growth accelerated in the fourth quarter and IC (integrated circuit) volume growth hit 70%.

Now what

Looking ahead to 2017, the market seemed to be disappointed by Impinj's guidance for the first quarter. The company projected revenue of $30-$31.5 million for the current period and adjusted earnings per share ranging between a loss of $0.06 and a profit of a penny. At the time of the announcement, analysts had expected a profit of $0.02 a share.

Weak guidance like this has a tendency to sink high-flying tech stocks like Impinj, but investors should me mindful that this a young company with a promising future ahead of it. Investors should remember to look past a single quarter's guidance.
