iRobot is known for its Roomba line of robotic vacuum cleaners. Bears worry about the threat of increased competition. Bulls, however, point to the huge potential for optionality (i.e. a company morphing and pivoting over time to become something we can't envision today). iRobot is already expanding its offerings into robotic lawn mowers, so it's not hard to imagine it going after other household and commercial applications soon. More broadly, though, there's a lot of room for pivoting into interesting spaces when you're an early ish mover into robots, machine learning, and artificial intelligence. It's hard to speculate on exactly what iRobot could become, but at just over $3 billion in market capitalization, it's still less than 1% the size of Facebook, Alphabet, or Amazon, meaning there's lots of room for the stock price to run if its wildest goals come true. And plenty of room for success in between if there's a more conventional outcome.
