At the center of everything we do is a strong commitment to independent research and sharing its profitable discoveries with investors. This dedication to giving investors a trading advantage led to the creation of our proven Zacks Rank stock-rating system. Since 1988 it has more than doubled the S&P 500 with an average gain of +23.89% per year. These returns cover a period from January 1, 1988 through March 3, 2025. Zacks Rank stock-rating system returns are computed monthly based on the beginning of the month and end of the month Zacks Rank stock prices plus any dividends received during that particular month. A simple, equally-weighted average return of all Zacks Rank stocks is calculated to determine the monthly return. The monthly returns are then compounded to arrive at the annual return. Only Zacks Rank stocks included in Zacks hypothetical portfolios at the beginning of each month are included in the return calculations. Zacks Ranks stocks can, and often do, change throughout the month. Certain Zacks Rank stocks for which no month-end price was available, pricing information was not collected, or for certain other reasons have been excluded from these return calculations. Zacks may license the Zacks Mutual Fund rating provided herein to third parties, including but not limited to the issuer.

About
Kevin Cook was a high-frequency institutional currency trader for nine years, starting with the introduction of the euro currency in 1999. Trading 100 million per day in the hyper-kinetic world of FX spot-futures arbitrage, and making continuous markets for size to the biggest banks and hedge funds in the world, he developed skills in global-macro analysis, technical trading, and large position risk management.
Applying his special focus on the keys to success in short-term trading and the dynamics of probability and risk, Cook went on in 2008 to develop options education for the retail arm of the Chicago options powerhouse PEAK6 Investments.
Cook published important perspectives about the psychological and quantitative fault lines in risk management in the summer of 2008 in SFO Magazine. He also represented PEAK6 as a market analyst on CNBC, Bloomberg, FOX Business, and CNN by providing live commentary on equities, commodities, options, and currencies. And he launched a daily webcast from the CME trading floors on the day that Lehman Brothers collapsed, naming the show Mark2Market to highlight where risk management worked and where it didnt before and during the financial crisis.
In 2011, Cook joined Zacks Investment Research to further expand his equity analysis, research, and trading skills.
