It doesn't mean the investor will benefit from it. I'm in a similar portfolio, but the truth is that many of that potential future growth is already priced in in today's price (meaning it is expensive to buy), and you may find, as an investor, to benefit more from investing in some lousy restaurant, or waste management company meaning investing in value etf).

Since what I wrote now is not for sure, you better stay diversified by investing in a core ETF like VOO, VT, VTI and don't make ANY tilt, we don't know which side (growth or value) will perform better in the future, and we don't know what is overvalued and what is undervalued now(it is a wild guess also, no matter many analysts saying this is cheap this is not, they are just guessing, too).
