      Well, impossible to do with certainty.

      But people are paid to try and do it at investment banks, and with enough outsider knowledge they can often get it right

      Of course that’s practically just gambling at a much greater scale

        they can often get it right

        They fail to outperform a broad market index like 85% of the time, and they charge fees for it lol

          Yeah, you’re completely right, I was more going for not impossible, but it’s even more luck than I realised
