I also had no doubts that the stock was overpriced at ipo.... this is my take on thier biz (MY OWN TAKE). They are a data broker, they face a number of obstacles
- Europe is enforcing every tighter privacy laws
- india, russian, china, brazil + other markets mainly use they homegrown alternatives
So thier main market is US based customers (due to USA almost non existant private data protection laws)
They are not going to increase their USA memberbase by huge numbers
Alot of thier USA customers are under 18 and thus have limited spending power.
An ever increasing number of thier customers access only via mobile devices .. thus see 0 advertising.
I predict that in the future as more and more US personal data makes it into public databases thier will be a public backlash and thus a tightening of those laws.
To me this adds up to a rapidly falling revenue stream, with ever increasing data storage costs, and unterminable future market. Espeacilly if they dont figure out how to incorporate advertising into the mobile app and fast.
