If an investor buys all the cattle weeks before eid at normal price and then sells at his desired price by manipulating the demand supply in market its haram.
Fir the beopari who has a fattening farm and sells it as per market price on eid is halal.
It really just the principle of it to determine if its halal
Its halal if market decides price based on demand supply. Manipulation of market to reduce supply and increase price is haram
The cars established price is x investor does market manipulation and sells high. Its haram. If var price were not established there won't exist any own. Anyone could ask for whatever price. And the market would settle on an understood price.
