Among his clients are all the largest investment companies, banks, pension funds and other institutional investors in the country (more than 600), as well as hundreds of thousands of individual investors working on the Can Slim system and receiving all the necessary information through the daily newspaper Investor's Business Daily, which he founded in 1984.
