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 MasTec (NYSE: MTZ) popped 17% today after the company reported blowout earnings numbers.

So what: Revenue rose 38% from a year ago to $992.2 million and crushed the $889.5 million in revenue analysts expected. Earnings per share were $0.37, which topped estimates by $0.02.

Now what: The company is benefiting from the energy transition taking place in the U.S., toward natural gas and renewable energy. These markets are exploding and now the company expects to earn $1.50 per share this year, instead of its old target of $1.42 per share. With shares trading at 12 times this year's new estimate and growth looking strong, I think shares can continue to rise as the company builds out our new energy infrastructure.
