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 +25% per year. These returns cover a period from 1988-2016 and were examined and attested by Baker Tilly Virchow Krause, LLP, an independent accounting firm. 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. Zack 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.
On April 4, 2006, the Columbus Dispatch reported that Blackwell "owned stock [83 shares, down from 178 shares purchased in January 2005] in Diebold, a voting-machine [and ATM] manufacturer, at the same time his office negotiated a deal" with the company. After discovering the stock ownership, Blackwell promptly sold the shares at a loss.  He attributed the purchase to an unidentified financial manager at Credit Suisse First Boston who he said had, without his knowledge, violated his instructions to avoid potential conflict of interest .
