It is possible to do well, even with insufficient information. Look at jet aircraft that are routinely landed without the ability to see the runway -- long before GPS was available. This is called flying with instrument flight rules.

Everyone only has a fraction of all the information. And you have to be satisfied with big returns in which you wonder, "how much of that was luck?" And, the occasional big losers. I can say I don't have 'the formula', but I'm returning 15% for over 20 years... knowing there is a ton I don't know. Which is something you find out when you are a patent attorney, and innovations come out of nowhere while MOST 'innovations' also lead nowhere.

Just. Have to be. OK. With. Not knowing.
