A group of people who work for companies that sell stocks (called analysts) give their opinions on whether a stock is good to buy or not. These opinions are called "recommendations." Many people think these recommendations are not very helpful because the analysts might be too positive about the stocks they sell.

There is another way to know if a stock is good to buy, called the "Zacks Rank." It is different from the recommendations because it looks at how much money the company is expected to make in the future, not just the opinions of the analysts. The Zacks Rank can be a better way to know if a stock is good to buy.
