3 Hot Growth Stocks That Recently Beat Wall Street's Expectations

Many companies beat Wall Street analysts' estimates in an accelerating economy, but fewer can do so in a slowing economy. As such, I think industrial software company PTC (NASDAQ: PTC), electrical products company nVent Electric (NYSE: NVT), and advanced materials company Hexcel (NYSE: HXL) -- all of which recently outperformed analysts' expectations -- are great stocks to buy now. Its software helps companies digitally create products (computer-aided design), manage them (product lifecycle management) from inception to physical creation and ultimately disposal, including servicing (service lifecycle management), while digitally connecting them (Internet of Things), and optimizing their performance (augmented reality).
