According to level 2, it was 2 large buys:
1. 498,964 shares @ .0517
at 3:48:30pm EDT
2. 502,103 shares @ .052
at 3:48:35pm EDT
VWAP was .0503549, though, so as encouraging as those big buys were, trading could resume back in the low channel on Monday, unless there's more stimulating news on open.
Time will tell.
Happy weekend to you!
