A sector I should really buy

It's strange the way sectors go in cycles. There's an element of cyclical business in many sectors, but investors know that. So, surely, if all investors had eyes for the long term, they'd factor in the cycles and share prices would not fly upwards in the short term during the inevitable up spells and crash back during the equally inevitable down spells.

But as we know, most institutional investors only have year-end results in mind, and that leads to cycles in the share prices too -- and long-term Fools can benefit from that.
