why iROBOT stock gained 21.4% in june

despite the big gains last month, iRobot's share price is roughly flat year to date.
iRobot gave a presentation for investors at the Baird Global Consumer, Technology & Services Conference in which it outlined growth outlooks for its products and the broader cleaning-robot market. Piper Jaffray analyst Troy Jensen then published a research note on June 12 stating that retail-channel reports suggested that the robotics company's sales for the quarter would likely come in above estimates. The note also gave iRobot an overweight rating and issued a $78 price target on the stock.
So what
At the June investor conference, iRobot broke down figures estimating that it has roughly 85% market share in North America, 31% in the Asian-Pacific geographic segment, and 71% share in the Europe, Middle East, and Africa market. The company still sees big room for expansion for both its Roomba and Braava lines as Internet of Things and smart-home markets expand. And it expects to sell roughly 5 million connected-device units in 2018 -- up from less than 2 million in 2017. The conference also highlighted plans to introduce several new products in the second half of 2018.

And iRobot stock appears to have received a positive catalyst toward the end of the month by way of the legal system. The company announced on June 26 that it had received a favorable preliminary determination upholding claims of intellectual-property violations that it had filed against companies including Hoover, bObsweep, and iLife.
