You can receive the average market return by buying a low-cost index fund. But you can make superior returns by picking better-than average stocks. Notably, the Penumbra, Inc. (NYSE:PEN) share price has gained 49% in three years, which is better than the average market return. It's also good to see a healthy gain of 27% in the last year.

So let's assess the underlying fundamentals over the last 3 years and see if they've moved in lock-step with shareholder returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...'

During three years of share price growth, Penumbra moved from a loss to profitability. So we would expect a higher share price over the period.
