Stock price when the opinion was issued
Likes the product. Concern is one of scale. How much bigger can it be, and how compelling is the product? Likes the cyclical aspect of increased ad revenues. Better ways to get access to those revenues, such as Google or a media content library owner.
Add to my position? Lacks an impressive history of ROI, so he doesn't even follow it. PINS doesn't even have a profit. Interesting that the stock shot up in July, which is a bullish signal and a good sign. In the high-$30s/low-$40s, add to your position.
