The spike added to the stomach-churning volatility that shareholders have been experiencing lately. iRobot's stock has been up as much as 70% -- and down by as much as 10% -- in just the past 52 weeks.
January's rally reflected rising optimism that iRobot had a solid holiday sales quarter. After all, Amazon.com announced in late December that robotic vacuums were among its best-selling items during the holiday rush, and that bodes well for the industry leader. (iRobot owns roughly 64% of the market for premium vacuum devices.)
At its latest quarterly check in in late October, iRobot raised its outlook after sales spiked 22% in the third quarter. CEO Colin Angle and his executive team believe revenue will now stop at $875 million at the midpoint of guidance.
Investors will find out on Feb. 7 whether the company hit that aggressive target or instead had to settle for something lower as competition ate away at its dominant market share in the robotic vacuum industry.
