Buying Calls and Puts of the same underlying and maturity

[botpro]

That of course makes no sense. A long (short) straddle can make sense depending on your view of future volatility. For example, a long straddle position can be viewed as a very crude trendfollowing strategy.

It was about stocks, not options.

Here are 3 generic cases (from https://en.wikipedia.org/wiki/Market_manipulation)
that authorities could make a court-case of:

- Wash trade: "Selling and repurchasing the same or substantially the same security for the purpose of generating activity and increasing the price".

- Bear raid: "Attempting to push the price of a stock down by heavy selling or short selling."[7]

- Quote stuffing is a tactic employed by high-frequency traders that involves using specialized, high-bandwidth hardware to quickly enter and withdraw large quantities of orders in an attempt to flood the market, thereby gaining an advantage over slower market participants.[8]
