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: Shares of heavy machinery maker Terex (NYSE: TEX) are building solid gains today, up by 24%, after the company reported strong third quarter earnings.

So what: The consensus estimates of $1.6 billion in sales and $0.23 per share profit don't compare to the $1.8 billion in revenue and $0.30 per share profit that Terex constructed for the quarter. The strength was a follow up to rival Caterpillar (NYSE: CAT), who also recently put up healthy numbers.

Now what: Terex also significantly cranked up its full-year revenue forecast, which it expects to fall in the range of $6.3 billion-$6.5 billion. The guidance is far higher than the previous range of $5.4 billion-$5.6 billion and the $6 billion that analysts expected. With the GDP figures released this morning showing growth starting to pick back up, construction spending should follow in suit.
