I'm sure they do, yet pump and dumps and short and distorts are something that happens each and every day. The SEC is only interested in the major cases.
On the revenue topic, buying a money losing company thats never been able to maintain a profit on their core business isnt really a very good idea, no matter what the revenue growth numbers. Thats like saying "You should buy this house. The rent you can get for it keeps going up and up and up! But you'll always lose money on it."
I suspect that Tivo will finally and once and for all win their suit against Dish, they'll collect their big chunk of money, they'll fritter it away over a period of a couple of years because they're managed by idiots, and someone will buy them someday when about all they have to offer is a patent portfolio thats declining in relevance.
But I dont think thats going to happen anytime soon and I'm betting the buyer will be someone in the software/advertising businesses like google or microsoft. Not dish or directv or any other programming intermediary.
After all, Tivo's soft spoken but quite obvious long term plan has been to replace the programming carriers with their box getting content directly from the programming providers, cutting the carriers out of the loop. Sadly, the prevalence of internet based content didnt happen by 2000, 2003, 2005 or 2008 like they thought it would. Its getting there.
