Why has the Adani Group shed US$90bn in value and what do short sellers have to gain?
Not that the short sellers will have captured that $90 billion, only some small portion of it. But it’s a pretty simple idea – those who bet on prices falling gain if and when prices fall.

Losing money if an allegation of spivvery turns out to be untrue is also an excellent incentive.
