Consumer focused companies are barely ever valued correctly, and it is the reason to invest in mature stocks with predictable incomes. Consumers are simply too finicky, and revenue is just too erratic. Today, I bought tech cominco(TCK), and later hypercom(HYC). I already have sell orders in, and we'll see how it goes (as an example).
These are just potentially poor decisions made by people with lots of money. Tech startups are inherently risky -- many more succeed than fail -- even if they are well funded. It is a fundamentally different equation than starting a bagel shop or a car wash.
