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 RTI International Metals, (NYSE:RTI) jumped 11% today after being upgraded by an analyst.

So what: JPMorgan's analysts upgraded RTI from neutral to overweight, and put a price target of $34 on the stock. The analysts said that the stock's recent pullback and increasing titanium demand from Airbus give the stock significant upside. 

Now what: Stocks often jump on analyst upgrades, but the increase in share prices often fades after traders get out of the initial move. RTI's stock is down 21% so far this year, in large part because titanium production increased faster than aerospace demand did, leading to a decline during the past few years. There's been a short-term increase in prices recently, but I'd like to see that be sustainable before jumping in, because there's not enough evidence yet that this is more than just a short-term price movement.
