Shares of lululemon are trading higher after Greenlight Capital’s David Einhorn concluded his presentation at the Value Investing Congress. Einhorn’s appearance came amid speculation that the famed short-seller may discuss lululemon negatively during his speech. Even lululemon CEO Christine Day, while speaking on CNBC on September 27, acknowledged she heard the rumors about Einhorn, but said she was not "not concerned." lululemon shares are up 2%, or $1.50, to $75.07 in late morning trading, in what looks to be a relief rally. Einhorn did, however, recommended short positions in Chipotle (CMG) and Green Mountain (GMCR) during his presentation.
