The best approximation I’ve found is S&P has this Top 10 index[1]. Over the last 10 years it has performed 18% annually vs 11% for the overall S&P 500, but that’s obviously been a historic bull run in large cap growth stocks. I can’t find data going back to 2000 to see how that strategy would have played out, but curious if someone else finds it or crunches the numbers.
Yeah, for what it's worth, my financial advisor is pushing me towards more value stocks and some more bonds. (I am somewhat older as well in addition to be in a position where being conservative makes sense.) Was just doing some research.
