Is Zacks Reliable? Your Questions Answered

Many investors searching for stock investment research discover and wonder: Is Zacks reliable?  
As you’ll see in this brief overview, Zacks has proven to be a trusted source for expert investing recommendations and powerful tools.

Why the Zacks Rank Should Be Part of your Investing Strategy

Through good markets and bad, Zacks has helped investors achieve their financial goals. The Zacks Rank enables investors to take advantage of trends in earnings estimates.

It is a unique, proprietary stock-rating model that utilizes earnings estimate revisions to help investors build a winning portfolio. There are four main factors behind the Zacks Rank: Agreement, Magnitude, Upside, and Surprise, and each one is given a raw score that’s recalculated every night, then compiled into the Zacks Rank. Using this data, stocks are classified into five groups, ranging from “Strong Buy” to “Strong Sell.”

Since its development in 1988, the Zacks Rank system has outperformed the market in 27 out of 33 years. In that time, it has averaged a return of +25.6% per year – more than double the S&P 500’s +11.3%.

An annual gain of +25.6% is more exciting than it may sound. Think of it this way: If you had invested $10,000 in 1988, it would have grown into more than $20 million dollars. The same investment in the S&P would only give you about $350,000.
