Jericho Capital Asset Management's flagship hedge fund plummeted 17% in October, ranking among the worst performers in the tech-media sector. Sources familiar with the matter said the decline wiped out all of the fund's gains for the year, pushing its year-to-date return to about -2%. Regulatory filings show that as of the end of June, Jericho held 29 stocks, with nearly half of its exposure concentrated in tech stocks, followed by telecom stocks. Its two largest holdings were application delivery company F5 Inc. and mobile advertising technology company AppLovin Corp., both of which fell more than 20% in October.
