Sum of long share positions in Form 13F reports for the quarter. 13F covers managers with over $100M in US equities; some positions are reported by more than one filer. The total is 117% of shares outstanding, so it counts some shares twice: positions reported by more than one manager, and lent shares that appear at both the lender and the buyer. Read it as an upper bound.
