Green Mountain Development Corp (GMND)

Could somebody explain the 2,100 shares traded so far today in GMND? Like that's $46 worth of shares. Why do I see tiny trades like that? Also the other day....I think on Monday, somebody sold 17,000 shares and the stock went down 20 something percent, then 15 minutes later somebody bought 1,000 shares and GMND gained back everything it lost with just like a $20 stock buy. I'm fairly new to trading but can't understand how a $20, $30 or maybe $50 transaction can move a stock so much. How can that possibly make any sense? Sorry I don't quite see how it's logical. Explanations? It sure seems like the price of the shares can be manipulated with very little amounts of money. Something doesn't look right and maybe somebody can explain how tiny tiny trades can move a stock 20% or more. How can that happen with GMND and even MPIX?
