The high growth expectations are already baked into the stock's price. To overperform, the company would have to exceed the high expectations. This is difficult. I would expect a backtest to show that moderate growth stocks do better.

What is "reasonably valued"? In backtests, momentum often boosts returns. Buying low-momentum stocks does not seem to work in general.

Just based on a straight average of S&P 500 stocks, the Healthcare and IT sectors have the highest average estimated growth (future 5-years). Consumer Staples and REIT have the lowest average estimated growth.
