Yesterday's drop was a logical one as Monday's rise was based on a single buy order for 2,000 shares that set the close price for the day. AGQ is still more than 30% above its year low which is something that not too many junior miners can say.
What moves the price is sentiment and one cannot expect much with gold and silver prices so severely punished. My advice to you would be to close down your computer and forget about the stock for a month or two. Then log on to the internet again and check the price.
Sentiment will return, with or without good news coming out. It's really all about sentiment in the mining sector.
