Insider activity at Sun Communities Inc has been all selling for a year now: about $27.7 million from three sellers, and zero buyers with their own money.
Selling on its own is common and often pre-planned (10b5-1 plans, taxes, diversification), so it matters more when it is unusually heavy or broad.
