(San Francisco)

Many investors are currently worried about the potential for a tech bubble. Between high valuations, data breaches, and a growing call for more regulation of the sector, it is easy to feel bearish. However, Barron’s is telling investors to not be too worried. The opinion is based on analysis of tech price movements and outperformance against a new Harvard study. Historically speaking, a bubble can be referred to as at least a 100 percentage point outperformance of a sector versus the market as a whole over a two-year period, followed by at least a 40% drop over the following two years. By that metric, the tech sector isn’t even close, as it has only outperformed the market by 36% over the last two years.

FINSUM: So this was a valuation-based study, but it could theoretically also be applied to individual stocks. When you do that, both Amazon and Netflix look vulnerable, as both have satisfied criteria for a bubble.
