Money managers are more heavily invested in technology stocks than they have been in at least nine years, a survey of portfolios shows.
"[Fund] managers appeared to have doubled-down on their winners," increasing exposure to technology-related stocks in portfolios by more than 14 percent for the year-to-date period, according to a new report from Bank of America Merrill Lynch.
Managers are 24 percent more overweight the tech sector relative to its weighting in the S&P 500, marking a new record in the firm's data history dating back to 2008, equity analyst Savita Subramanian explained in a Friday note to clients.
On Thursday, Google's parent company, Alphabet, reported better-than-expected first-quarter profit and sales, which were fueled by growth in mobile search and ongoing strength in YouTube ad sales, the company said.
On Friday, both the Nasdaq and the Nasdaq 100 indexes reached all-time intraday highs, with Alphabet, Amazon, Facebook and Microsoft having the most positive impact on the Nasdaq 100 through morning trading.
For the year, the Technology Select Sector SPDR (XLK) has risen more than 12 percent, compared with the S&P 500's nearly 7 percent gain. That's the best return among the market's major sectors.
But the equity strategist believes this is not necessarily a good thing for tech investors.
"Buying the 10 most underweighted stocks and selling the most overweight stocks ... has generated alpha in past years," Subramanian wrote. This implies that, despite the excitement in the sector, it might be time to for a sell-off in tech.
"[S]o far performance in 2017 has bucked the trend," she added.
