Stock price when the opinion was issued
In addition to the 200-day MA, he looks at peaks and troughs. Look at the last low and the last high. The next high hit the previous high, so that's two relatively similar peaks. The stock may be below the 200-day MA (1st rule to sell), but it hasn't dropped below the last trough (2nd rule to sell). As long as it holds above the last trough, you're safe.
Don't go into full panic right now. Hold for now; if it breaks that second rule, then get out.
Superior retailer, steady and consistent revenue and bottom line growth for at least a decade. If you don't need cash tomorrow, it's always been a mistake to sell. Not huge growth (~6-8% topline, 11-12% bottom line), but growth nonetheless quarter after quarter.
Historically trades around 30x earnings, a deserved premium. Announced subscription increase and stock took off along with the multiple at close to 50x. Lots of exuberance in the stock, be cautious. Wait for pullback to $700 level.
