AUMN (due small public float) appears to be subject to sudden price jolts (selling and buying frenzies) whenever deep pockets add or reduce their positions. Quick drop this AM came on a surge in selling from somebody (perhaps thinking the closing of PP at $18.50 will cause a drop).
From recent pr: "The Offering is expected to close on or about October 21, 2010"
Don't like the volatility but getting more used to it.
