At the top its says holder shares out value %. what exactly does that mean?? Is it saying how many shares these people sold?
im sorry its suppose to say holder then shares then % out then value. This is suppose to be a graph. im jsut wondering what %out means.
It's an abbreviation for "the percentage of total shares outsanding" represented by the number shown in the column to its left. More information here: https://en.wikipedia.org/wiki/Shares_outstanding
but is there a way to know whether the shares that these institutions are holding are shorts or longs??
Shares are neither "shorts" nor "longs": they're units of ownership. More information here: http://www.investopedia.com/terms/s/shares.asp
In the list that you are referring to (If i'm correct in assuming it's taken from morningstar.com), they are long positions only.
