Who would like to hazard a guess as to where the stock will close 48hrs after the company News/Press release comes out? It will depend entirely on the contents of the Press Release. If it is "We've secured a contract to sell 10,000 gal per month of Petrozene to ExxonMobil" then I think it would go up a lot. If it's more of the "we are in the final stages of [something]" then I think it would not go up much. If it's talking about a non-Petrozene (and non-Aqueous) endeavour, I would suspect it would go trend down. (I'm betting on the middle case).
