According to Indian regulators, every trading day Jane Street would:

1) buy large volumes of stocks and/or stock futures that are part of an index tracking India’s banking sector, early in the day,

2) subsequently place large options trades, betting that the index would decline or volatility would spike later in the day, and

3) later in the day, cash out of the large long positions, dragging the index lower, making far more money on the options trades than on the long positions.

Jane Street can and likely will claim the firm was only arbitraging away pricing inefficiencies, nothing more, nothing less. It was just business as usual, etc., etc.

However, given the scale of the operation, Jane Street's actions sure look like textbook market manipulation. Calling it like I see it.

Don't know about Jane Street, but that sounds like a general problem.

If options & futures are more liquid than the underlying, someone will be tempted to nudge the underlying.

Bond ETFs and their options chains seem like another locale where this could happen.

I have a suspicion this has been happening with a particular MAG7 stock these last few months, but I can't fully convince myself such a large stock can be manipulated like that.

At least one of those stocks tends to have a comparatively thin order book.

Any stock with large retail options trading volume is ripe for shenanigans, and I can bet tsla is one of them.
