(San Francisco)

There is no doubt about it, the FAANG stocks—Facebook, Apple, Amazon, Netflix, and Google—were a huge force is delivering 2017’s great return. But it might be time to remove them from your portfolio, at least as Barron’s argues it. And if not removing them, then at least reducing exposure. The stocks count for a huge portion of many funds, so investors may have more exposure than they realize. The stocks have seen a massive run-up in valuation, but that makes them look increasingly vulnerable. Barron’s also cites the increasing risk of regulation of the sector, which could prove a weight on values.

FINSUM: The tech industry has grown very large and dominant, and seems to have its own cycle versus the rest of the economy, all of which makes it very hard to call a top. There are some dark clouds gathering on the horizon, but nothing looks like it is imminently going to bring the FAANGs down.
