Technology sector in February 2018

Major sectors of the S&P 500 Index (SPX-INDEX) contributed to the S&P 500 Index’s sharp drop in February 2018. However, the technology sector saw only a marginal drop, which helped control the index’s overall fall.

The Technology Select Sector SPDR ETF (XLK), which tracks the performance of the US technology sector, fell marginally by 0.4% in February 2018. However, the technology sector remained the top performer of the S&P 500 Index with a 34.6% return in 2017. The broader market S&P 500 Index (SPX-INDEX) fell 3.8% in February 2018.

Alphabet (GOOGL), Facebook (FB), and Apple (AAPL) returned -6.6%, -4.5%, and 6.8%, respectively, in February 2018. Some technology stocks’ weaker performances were offset by the stronger performances of other technology stocks during the month.
