We do our best DD and place our "bets". We can only analyze information available to us outside SHs. The alternative is to get "inside the enterprise wall". The trade off to being an "insider" is that buying and selling shares are restricted/regulated. Insiders that have knowledge of positive information may sleep better than outside SHs, but the downside is that their investment is locked down until full disclosure is made to the public. At least, that is how it is supposed to work.
