Corning Incorporated (NYSE: GLW) recently reported its second quarter earnings and even a cursory glance at the results show healthy growth in nearly every meaningful metric. The company’s core sales increased to $2.6 billion, a 6% increase year over year, and its core EPS increased to $0.42, a 14% increase over 2016’s second quarter. While the stock price immediately dipped after Corning reported earnings, long term, buy-and-hold investors know to focus on a business’s underlying fundamentals, not short term price volatility.
