Not to be creepy here but if I had several million shares plus, my life savings invested here I'd hire a P. I. to follow a few of AMBS's decision makers. See where they're going; looking at potential spaces, and whom they're meeting with during the day; lunch and dinner; CEO, Presidents, Commercial Real Estate Agents, moving companies etc. You can bet your ass that's what sports teams, 500 Companies, and hedge funds do before hiring or offering top tier positions and investment funds. What's a few hundred to a few thousand dollars when you are talking about these potential gains or loses? Covert DD, just saying... Hahhahaa
