What is the ruling on purchasing shares of companies that are manipulated by some people, whether the manipulation is obvious or not?

Investing in the stock market (bourse) is permissible for shares of companies engaged in lawful activities and which do not deposit their funds in usurious banks. This permissibility is conditioned by detailed requirements mentioned in Fatwa No. 10779, taking into account the resolution of the Islamic Fiqh Academy. The manipulation of shares by some traders does not prohibit dealing in what is permissible among them.
