This is no ordinary times... My all stocks 401k this year is going up 10% a month (with no funding, I'm retired early). It's actually the gauge I us for how well I do with my trading!99% of the average joes who buy stocks are still no multimillionaire.
This means that they missed many opportunities the last years: Apple, Tesla, Facebook, Amazon, Google...
Conclusion: playing your cards right seems impossible for the majority.
