"Simple" question: what do you think will generate better results for Joe average investor during his lifetime...holding up to 5 funds and hardly trading, or using 10+ holdings with more trading?

Let's not conflate trading with the number of funds an investor holds.
They're two different topics.
There has been ample research indicating investors who trade frequently often fare poorly.
You may be familiar with the seminal paper titled
“Trading is Hazardous to Your Wealth: The Common Stock Investment Performance of Individual Investors” by Brad Barber and Terrance Odean.
Your prior post stated:
"I could never understand why anyone has more than 7-8 funds (they are usually the ones who say, there is no right number). You go over 10 funds and you are over-diversified. What usually happens with over 10 funds? you are not sure and/or you have owned lagging categories for years. You already know that the SP500 beat most funds over 15-20 years so why do you own so many funds? This was my initial start (1995-2000) investing 90+% in VG Total index and the rest in VG growth."Regardless of your opinion, there isn't an arbitrary number of funds which is optimal for every investor's unique circumstances. A young investor who is risk tolerant and has many years until retirement can reasonably have only a single fund in their portfolio (e.g., Total World Stock Index fund or target-date fund) if they so choose. Many Bogleheads are fond of a three-fund portfolio often comprised of Vanguard Total Stock Market Index Fund (VTSAX), Vanguard Total International Stock Index Fund (VTIAX), and Vanguard Total Bond Market Fund (VBTLX). This is a good strategy but it may not be right for everyone. Investors with multiple accounts should probably consider fund availability, optimum asset location, tax consequences, risk tolerance, and personal preferences when constructing their portfolios. These considerations can lead to having more funds than you prescribe. Bottom line - there isn't a one-size-fits-all solution.
The S&P
500 performed very well over the trailing 10-year and 1
5-year periods.
It was a very different story during the "Lost Decade" (2000-2009) when the S&P
500 basically went nowhere.
Would the average investor with a large S&P
500 position have the fortitude to stick with this investment
during the "Lost Decade" or would they have sold before the S&P
500 recovery started?
Wouldn't it have been beneficial to also include foreign stocks and/or investment-grade bonds in the portfolio?
