If you would like a cheap stock to buy, that has potential for huge gains look into OMEX which is Odyssey Marine exploration.
They just got the contract to retrieve the remaining gold from the ship SS Central America that sunk in the 1850's carrying gold from California to New York City off the shores of South America. In the 1990's half of the known gold was recovered, but because of lawsuits and claims on the gold, nobody was allowed to touch it until last month when Odyssey won the contract. The half that is left is valued around 60 million, with I believe 80% of all recovered gold going to Odyssey. Here's the kicker though, there is supposedly 15 tons of government gold on the ship as well, that is included in the 60 million haul. If that is true the value of the gold down there could be closer to 125 million. Anyways, the stock is like 2.20 a share, so it might be worth investing a couple hundred dollars on the chance that OMEX hits it big and the stock spikes.
