Earnings Follow-Up

IRobot is today's proof of why I am overly cautious when it comes to earnings reports. Note the nice multi-month base that formed. Also see the breakout on heavy volume on October 19, 2020. Then on October 20 the company reported it beat earnings by $1.58 per share (estimate of $1.00 per share, actual earnings of $2.58 per share). And . . . the stock drops as much as 15%!!
