weekly turnover-who is buying?

from recent annual report, it stated that top 20 shareholders owned 65.66%, around 1,300M shares. balance 34.34%, around 680M owned by 6639 shareholders. among 6639, 3281 owned less than $500 parcel, i.e. less than 15,000 shares in average, that will make up around 48M. remaining 3358 (6639-3281) owned 632M shares. from my record, since 17/8/09 to 20/11/09 shares rise from low 1.3 to 5.6 ended on week 20/11, with a turnover of over 500M shares traded. Presuming if top 20 shareholders are not selling and buying during 17/8 to 20/11, then over 70% (500M /680M x100%)have changed hand. THEN WHO IS BUYING SP FROM 1.3 TO 5.6? appreciate if some of you can tell me the answers?
