Flowserve (FLS) Upgraded to Strong Buy: Here's What You Should Know

Flowserve (FLS) could be a solid addition to your portfolio given its recent upgrade to a Zacks Rank #1 (Strong Buy). An upward trend in earnings estimates -- one of the most powerful forces impacting stock prices -- has triggered this rating change.

A company's changing earnings picture is at the core of the Zacks rating. The system tracks the Zacks Consensus Estimate -- the consensus measure of EPS estimates from the sell-side analysts covering the stock -- for the current and following years.

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.

As such, the Zacks rating upgrade for Flowserve is essentially a positive comment on its earnings outlook that could have a favorable impact on its stock price.

Most Powerful Force Impacting Stock Prices

The change in a company's future earnings potential, as reflected in earnings estimate revisions, and the near-term price movement of its stock are proven to be strongly correlated. That's partly because of the influence of institutional investors that use earnings and earnings estimates for calculating 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.

For Flowserve, 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.
