Whatever people are doubting may be an investment opportunity. Agriculture in the United States is pretty depressed right now. This may be an area where there is an investment opportunity. However, you should be cautious about investing in an area just because it is depressed right now because that area could stay depressed for a very long period of time. This is why you have to find a change that is taking place as well. If you can find something cheap and if you can find a positive change, maybe you should do more homework and find an investment.
The change, or catalyst, could be anything. I want to emphasize that even when you see the catalyst, it is futile if everyone else sees it too and the effects come in quickly. It usually takes a while for the catalyst to work its way through.
