Tech stocks generally carry more risk than other stocks, but they also promise significantly more growth. Throughout much of the 21st century's historic bull market, tech stocks have been at the forefront of the rise, with the biggest tech stocks all outperforming the S&P 500 over the past five and 10 years. There's a fundamental reason why tech stocks tend to attract more investor demand than other kinds of equities. This has added to optimism that tech stocks, in particular stocks which have already seen big gains, will still be a safer longer-term bet," Streeter says. If an investor wants the highest possible appreciation, they would do well to devote a segment of their holdings to tech stocks.
