Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Strong results from Deere (NYSE: DE) lifted stocks of other companies specializing in farm and construction equipment and replacement parts. Count Terex (NYSE: TEX) among the winners. The stock surged more than 10% before closing up 8.7%.

So what: Several direct peers rallied as well. Manitowoc (NYSE: MTW) jumped more than 9% while Caterpillar (NYSE: CAT) gained more than 5%. The implication? Deere and Terex aren't likely to be the only benefactors of rising demand for agricultural equipment.

Now what: Numbers speak to the opportunity. A recent estimate from Global Industry Analysts says demand in Asia will rise 7.8% annually from now till 2017, at which point it pegs the entire market will be worth $122.9 billion.
