All You Need to Know About Corning (GLW) Rating Upgrade to Strong Buy

Corning (GLW) could be a solid addition to your portfolio given its recent upgrade to a Zacks Rank #1 (Strong Buy). This rating change essentially reflects an upward trend in earnings estimates -- one of the most powerful forces impacting stock prices.The sole determinant of the Zacks rating is a company's changing earnings picture. The Zacks Consensus Estimate -- the consensus of EPS estimates from the sell-side analysts covering the stock -- for the current and following years is tracked by the system.The power of a changing earnings picture in determining near-term stock price movements makes the Zacks rating system highly useful for individual investors, since it can be difficult to make decisions based on rating upgrades by Wall Street analysts. These are mostly driven by subjective factors that are hard to see and measure in real time.Therefore, the Zacks rating upgrade for Corning basically reflects positivity about its earnings outlook that could translate into buying pressure and an increase in its stock price.Most Powerful Force Impacting Stock PricesThe change in a company's future earnings potential, as reflected in earnings estimate revisions, has proven to be strongly correlated with the near-term price movement of its stock. The influence of institutional investors has a partial contribution to this relationship, as these big professionals use earnings and earnings estimates to calculate the fair value of a company's shares. An increase or decrease in earnings estimates in their valuation models simply results in higher or lower fair value for a stock, and institutional investors typically buy or sell it. Their bulk investment action then leads to price movement for the stock.For Corning, rising earnings estimates and the consequent rating upgrade fundamentally mean an improvement in the company's underlying business. And investors' appreciation of this improving business trend should push the stock higher.Harnessing the Power of Earnings Estimate RevisionsAs empirical research shows a strong correlation between trends in earnings estimate revisions and near-term stock movements, tracking such revisions for making an investment decision could be truly rewarding.
