Coherent (COHR) Upgraded to Strong Buy: What Does It Mean for the Stock?

Investors might want to bet on Coherent (COHR), as it has been recently upgraded 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 Zacks rating relies solely on a company's changing earnings picture. It tracks EPS estimates for the current and following years from the sell-side analysts covering the stock through a consensus measure -- the Zacks Consensus Estimate.

Since a changing earnings picture is a powerful factor influencing near-term stock price movements, the Zacks rating system is very useful for individual investors. They may find it difficult to make decisions based on rating upgrades by Wall Street analysts, as these are mostly driven by subjective factors that are hard to see and measure in real time.

Therefore, the Zacks rating upgrade for Coherent 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 Prices

The 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 transaction of large amounts of shares then leads to price movement for the stock.

Fundamentally speaking, rising earnings estimates and the consequent rating upgrade for Coherent imply an improvement in the company's underlying business. Investors should show their appreciation for this improving business trend by pushing the stock higher.

Harnessing the Power of Earnings Estimate Revisions

Empirical research shows a strong correlation between trends in earnings estimate revisions and near-term stock movements, so it could be truly rewarding if such revisions are tracked for making an investment decision. Here is where the tried-and-tested Zacks Rank stock-rating system plays an important role, as it effectively harnesses the power of earnings estimate revisions.

The Zacks Rank stock-rating system, which uses four factors related to earnings estimates to classify stocks into five groups, ranging from Zacks Rank #1 (Strong Buy) to Zacks Rank #5 (Strong Sell), has an impressive externally-audited track record, with Zacks Rank #1 stocks generating an average annual return of +25% since 1988.

Bottom Line

Unlike the overly optimistic Wall Street analysts whose rating systems tend to be weighted toward favorable recommendations, the Zacks rating system maintains an equal proportion of "buy" and "sell" ratings for its entire universe of more than 4,000 stocks at any point in time. Irrespective of market conditions, only the top 5% of the Zacks-covered stocks get a "Strong Buy" rating and the next 15% get a "Buy" rating. So, the placement of a stock in the top 20% of the Zacks-covered stocks indicates its superior earnings estimate revision feature, making it a solid candidate for producing market-beating returns in the near term.
