The XBI or any index follows the action of its constituents, not the other way round.



The "constituents" are the index funds and exchange traded funds that control 70% to 80% of trades using automated computer trading. Passive investing using algorithmic models took over the markets/exchanges long ago. Gone are the days when most trading originated from research done by humans. Machine trading is the reason for the extreme volatility of today's markets and that volatility has very little to do with changes in business fundamentals.
