I think they accumulated on prior after markets & the volume today and yesterday was insufficient to bleed their shares down during those days. So, the abscence of after market buys after a low volume day confirms, for me anyway, the question I'd been debating regarding whether the buys represented:
1. post market settling between MMs
2. buys by the mutual fund cwoody found
3. buys by MMs of an "inventory", as it were, from which to trade the expected upcoming volume days
I have selected #3 as my choice. Could be wrong, but thats how I see it. I still like that mutual fund though. Park it in an IRA and leave it, maybe.
