It's quite funny to just search "nasdaq index" on google, then switch to "Max" and see the graph. You see a quite step growth starting February/March 2016 that doesn't seem completely rational. Also lately, you have a kind of plateau with some hiccups. I've the feeling that the bubble will burst withing a year, and next year or two, most tech companies valuations will be halved. But it's only a feeling, I've no deep rational behind it.
