If you need 5000-10.000 hours of study to become a day trader with no guarantee that it'll turn out successful in the end - what's the opportunity cost here if he had done something else instead?
You should do this in your free time, while having a regular job.
Do you calculate the opportunity cost of:
- sporting
- going out
- holidays
- ...
also? That would mean that you should just work 24/7 to avoid any possible opportunity cost. You will then be happy if you will die to get ride of this opportunity cost. How much was the opportunity cost of posting this on ET for you?
No, but it's a good benchmark for what he should expect to happen.
Almost all billionaires, successful sportsmen, successful traders, lottery winners, etc... should not have expected it to happen. But they in REALITY did it. Stats are only good if applied on lots of data to have any value. Each single data point can not use the global stats to define their individual chances of succeeding.
Benchmarks are based on statistical calculations of a lot of data and can only be used on lots of data to get a reliable result, within certain limits.
I am one of the living proof that the benchmark did not work for me as a reliable prediction in trading.
So is Zuckerberg, Siegel, Buffett, Gates, Tudor... They all did what statistically was almost impossible in their area.
