I have some shares in a company called keller group in the construction and materials sector which took a huge dip this morning. Is this sector expected to make a recovery or carry on falling?

10% daily move in any micro-cap stock should not be surprising in this environment.

You are in luck. The motley fool have a discussion on this:

I think basically a generally tanking market.

I'm sure they'll rebound because house prices only ever go up. Wait, no, hang on, err, umm ...
