NEW YORK ( TheStreet) -- Jim Cramer says author, entrepreneur and brand expert Daymond John told him during his visit to "Mad Money" last week that he has to reinvent some of his brands when they get tired, he told Nicole Urken, "Mad Money's" research associate, Tuesday.Urken said Daymond's index was up 45% while the S&P was up 33%. In his portfolio, even the underperformers are starting to come back. Cramer said one of Daymon great calls was to "sell BlackBerry ( BBRY)" because he thought BlackBerry had lost its cool and was not going to be a contender in the future. How right was he." "Daymond understands what people want," Cramer said, "and that does translate from his performance into what people want in the stock market." --By Anthony Buccino in New York.
