Insiders are often very overexposed to a single company because it's their primary form of compensation. You can sell every share you have and still be overexposed due to unvested shares. I would advise against interpreting "I don't want to tie my life savings to this company" as a lack of faith.

Absolutely. But I suppose if you still hold some vested stock, it might mean you are optimistic in spite of the high exposure.
