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 Anterix basically reflects positivity about its earnings outlook that could translate into buying pressure and an increase in its stock price.
