Yeah, I think volatility in the indian market was way too low, and Jane street just juiced it. normally that would be a losing proposition, but too many existing players were short volatility habitually… answer is not to kick Jane street out, but to enjoy the taxes Jane street pays on the gains…

Low volatility is good for everyone engaged in long term asset management. Jane Street just found a way to make everyone else less money while making a small amount for themselves.

According to who?

There are plenty of pension funds nowdays that have people specialized in picking up mid sized companies after big drops.

it’s a known effect. Without going into details here, you can calculate first crossing time of a barrier in a stochastic process and observe that often the first crossing time decreases as the volatility increases. From there you can set one barrier at 0 (default) and draw your own conclusion.
