Gas prices, Conservative government, and Our stock market

<p>Okay so this is a random question but I would like an answer because I'm a little confused.
I follow the stock market quite a bit.
Ever since the distress in Libya, some oil plants have been shut down. Accounting for 2% of US oil. With this decrease in exportation of oil to US the gas prices have risen up to 3.78 a gallon, I saw it today. Gas prices is a big issue in US right now. So you would think that they raise the price to compensate for their loss in Libya, which is only 2%. But with less oil for companies like chevron, exxon, etc.. I would think, correct me if I'm wrong, that the shares for those companies would not be inclined to raise or at least stay consistent. No, they are rising, not exponentially, but quite a bit since a couple months ago, for example, chevron in November 30, 2010, a share was worth 81$ approximately, today it is worth 107$. I may be looking at this without a different perspective, but I only see this. Can the government, or oil companies, be stimulating our media to give false information, such as plants shutting down. Because in my opinion, and view, it seems it hasn't shut down, and now that the prices are even higher, the companies are getting more revenue, making the stock worth more, eventually bettering the economy but at our expense. Could government be behind this? Am I completely getting this wrong? What's going on?</p>
