Forum to know reason for equity movement

Is there any forum / discussion blogs to know why perticular stock has rallied.

Exa- auropharma on Friday (11june) moved 5% . I couldn’t find any technical breakout or press news related this.

Not completely sure about this but from the information that I could find, the company shared an exchange announcement at 11:45 AM on 11th June 2021 (about releasing its earnings call transcript) and the stock rally started from 12:15 PM (with increased volumes from around 01:00 PM) -

The reason why I am unsure about the exchange announcement causing the rally is because the Earnings Call audio was public from 31st May 2021 itself -
