Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Range Resources (NYSE: RRC) popped more than 19% in early trading after reports that Royal Dutch Shell (NYSE: RDS-A) could make a bid for the business.

So what: The Wall Street Journal has since reported that Shell is uninterested in purchasing Range, yet that hasn't deterred the speculators. The stock remains up more than 7% as of this writing on roughly five times the average daily trading volume.

Now what: The Journal's reporting may have something to do with the surge. Rather than deny the rumors outright, the paper said that Range Resources "hadn't been formally approached" and that there were no talks about a deal at present -- all of which could mean that there were informal talks. Do you think Range is a ripe acquisition target? Would you buy at current levels? Please weigh in using the comments box below.
