Shares, value and weight are as reported in the file, dated by the data source's last update of it (not the date of the positions), never adjusted; a split warning appears only for a split close to or after that date, and its absence does not mean the count is on today's share basis. Weights as the fund reports them. Leveraged and inverse funds list swaps and cash, so weights can be negative or add up past 100.
