    Are investors idiots?

    A lot of investment is driven entirely by HFT algorithms and AIs now. The brokers oversee the broad strategy, but the trading is just a dozen different multi-billionaire hedge funds chasing one another’s tails.

    And because the market is increasingly liquid - as more mega-investors like Buffet cash out in pursuit of future buying opportunities - you’ll see sudden sharp inversions caused by the sheer amount of buying power that’s being pent up and released between announcements.
