Yeah, the math is painful. But that's what happens with an extremely illiquid, small cap, penny stock. You only need 2 people to agree on a price, any price, for it to move a huge %. Since it's so illiquid, there isn't much of a market for OMAG (yet) and so even a nickel movement gets to change our "market" price.
The point to keep in mind, and this is key to keeping your sanity, is that the number of shares changing hands is so tiny that it just doesn't matter. If you saw 10,000s of shares trading down a nickel, then panic. But if its only a few hundred or even a few thousand, it's not a market movement ... it's one guy lightening his / her load a little or giving up.
Remember what an earlier poster said today ... it's the brass ring we're all waiting for! Until then, it's all a game of nerves!
