While the Nasdaq Composite Index is creeping up on a record set when software and semiconductors called its tune, the latest leg has been driven by technology that barely existed 15 years ago.

Companies tracked by the Solactive Social Media Index have surged 15 percent this year as LinkedIn Corp. and Facebook Inc. posted gains at least four times larger than that for the Standard & Poor’s 500 Index.
