I'd be interested in proof/data (if it is even possible) rather than "some investment banker claims", etc.
The finance industry is huge and even softbank with their $100 billion is a tiny player in the market especially one as large and liquid as the nasdaq.
What about the nasdaq rally from 2009 to 2020? What that softbank as well?
The world flush with cheap capital, money flooding to the US because of tensions around the world, election year rally, etc seem far more plausible cause than softbank.
Softbank by itself isn't remotely big enough to move markets for such a long period of time to set a trend.
The analysis covers that. The idea is that options magnified the effect of their billions and set off a chain reaction. When you analyze the flows, they are anomalous. It may not be the reason, but it’s plausible and worth further investigation.
