If. But thats not the case. BMN shares are hardly the only shares changing in volume in their portfolio.

And even if it was it still doesnt mean I am wrong because you dont understnad how index funds can be managed.

If BMN is one of the few shares dropping in value in their asset pool (e.g. PDN and ERA are relatively stable lately), and theyre maintaining the same asset split then any new investment in the fund would result in more BMN shares being bought with little to no other movement.

I am not saying they do not believe in BMN. I am just saying that I think you are over thinking the importance of their investment in BMN.
