Is it permissible to deal with Star Capital company based on the following information: that it provides annual reports on its past dealings, sets a maximum loss limit of 3% through a stop-loss order, and deals directly with banks rather than brokers, and therefore does not charge overnight fees and does not operate under a leverage system?

If the transaction is free from Sharia (definition) prohibitions, such as guaranteeing a portion of the capital in Mudarabah (definition), or dealing with overnight interest and leverage, then there is no harm in dealing with the company and investing money with it, bearing in mind that the fatwa (definition) is based on the questioner's description of the transaction.
