Noah Berger/Reuters It's been smooth sailing this year for anyone in the stock market who bet on big tech companies. The so-called FAANGs, including Facebook, Alphabet, and Netflix, have earned their stripes in 2017 by outperforming the broader stock market and being responsible for much of its gains. That's partly why stock pickers are having a strong year — they held a record overweight position in tech. And so, for fund managers heavily weighted in the so-called growth sectors, 2017 has been a good year.
