LONDON -- Even in a year when the FTSE 100 has already advanced 9.2%, some blue-chip shares have room to move higher still.

Here are three shares that could deliver big returns in the short term.

1) BP
If BP (LSE:BP) (NYSE:BP) shares were to rise 20% from here, the company's share price would be 540p. Since the Gulf of Mexico disaster, the highest that the shares have traded is 500p.

BP shares currently trade on a 2013 P/E of just 8.1 times forecasts. The company is expected to pay dividends that add up to a 5.4% yield for this year.

BP shares are currently being held back by worries over an ongoing court case relating to the Gulf of Mexico disaster. If the result is anything other than a huge fine for BP, expect the shares to rise immediately.

BP's new deal with Rosneft could also transform investor perceptions.

2) Royal Bank of Scotland
In January this year, shares in Royal Bank of Scotland (LSE:NWG) (NYSE:RBS) were changing hands for 370p. That's 18% ahead of where we are today.

Sentiment toward the banks has been battered by Payment Protection Insurance miselling, LIBOR fixing, and interest rate swap miselling. Due to a collection of (hopefully) one-offs and technical accounting reasons, RBS was forced to report a huge loss for 2012.

This has shrouded the bank's recovery. By a number of measures, RBS is fast-improving. As so few commentators are mentioning the good news from RBS, this feels like a point from which sentiment can only improve.

3) Kazakhmys
Kazakhmys (LSE:KAZ) is one of the most volatile shares in the FTSE 100. It always has been.

So far in 2013, Kazakhmys shares are down 28.2%. In the last year, the shares are off by almost 40%.

Kazakhmys is a copper miner. As such, its share price is a geared play on the price of the raw material and the global economy. When the price of copper reached a peak back in October, Kazakhmys shares were 40% higher, at 770p.

If copper can turn higher, Kazakhmys shares will soar.

The shares trade at just 7.4 times expected earnings for 2013, with a forecast yield of 1.8%.
