Look at it this way: 7% compounded monthly means 125% gains annually. Warren Buffett, one of the most successful long term investors of all time, only managed 18% gains annually. Some newer investors (Joel Greenblatt, Mike Burry) have averaged 30-40% annual returns but don't have the length of track record of Buffett.
For him, its really a matter of how much money he has to put to work. This is probably in part why Burry can make the returns that he does, he doesn't have a $200B anchor around his neck.
For an inexperienced individual to make those returns (10%/mo) would likely be more risk taking than alpha generation. It's hard to describe exactly what would be involved in getting to the stage where you could do this reliably (alpha generation) because there are different routes to get there (fundamental, quant, high frequency), but it would likely involve quitting your day job and also likely involve getting a day job that involves asset management. And not the hot-air sales kind like Wealth Management/Private Banking, more like the hedge fund/portfolio manager kind.
No, not possible.
