Re: Question about "The Index"
Probably pretty arbitrary. They pick a style for the funds investments and then decide which index most closely follows that style. Sometimes an index is 'invented' to help benchmark a managed fund...for example there is a wellington and wellesley 'index' that vanguard has created by allocating certain equity and bond indexes by percentage.
Be fearful when others are greedy, and greedy when others are fearful. Just another form of "buy low, sell high" for those who have trouble with things. This rule is not universal. Do not buy a 1973 Pinto because everyone else is afraid of it.
