Serge Berger from thesteadytrader.com explains why he thinks Caterpillar is a buy. The US stock market has been quiet the past couple of weeks with pockets of movement. Berger has been looking for stocks that 'climb' the wall of worry' and look favourable from a technical perspective. Even though there is a negative view of Caterpillar from analysts, the stock continues to go higher.

Berger expects to buy at $83.80 with a stop at $82. The price target is $86.50.
