401k Investing for Newbies and Nerds
There are 90 million American workers who have collectively own $14 trillion in their 401k accounts. They face both challenges and opportunities. The largest opportunity is that their accounts are investment accounts, not savings accounts, and for the past three decades, many have grown their balances in the low double digit range. Those with the highest return have constructed portfolios that focus on index funds and avoided target date funds.
The main challenge 401k owners face is that there are required to make their investment decisions by choosing from a limited menu of mutual funds. 42% of 401k participants have found that including index funds in their portfolio has provided them with results that optimize their investment experience.
The 90 million 401k account owners can be divided into 3 categories. The first are those who could care less about their money and are willing to just take what they are given. The second group, NEWBIES, are inexperienced in the investment process, but are willing to become engaged in the management of their hard-earned dollars. The third group, NERDS, are those who have a modicum of investment expertise and are willing to devote the time and energy to expand their investments skills.
My mission is to motivate 401k participants and their employer plan providers to become engaged in their account and then train them how to optimize their results.
I have a 62-years of stock market experience. I have been a stockbroker, finance professor and individual investor. I have no investment products to sell. All I have to offer are the objective observations of one who has been there and done that.

Season 2 Episode 2 All That Glitters Is not Gold
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
During my second junior year in college, I took a Shakespeare class. I was a business major and wore a coat and tie to class. In a roomful of liberal arts majors, it was obvious that I was the class nerd. The only line I can remember from the lectures was, “All that glitters is not gold.” Full disclosure: I had to Google “Shakespeare” to make sure I had the proper quote. It comes from the Merchant of Venice and is a warning against being misled by outward appearances.
But getting back to Shakespeare’s all that glitters is not gold thing. There are 8,314 mutual funds available to the investment public. In calendar 2025, just 11% of these 8,314 mutual funds beat the market. Their average gain was 13.5%, barely half the 25.7% total return of the market.
Which begs the question? What is the market? The gold standard for the market is the S&P 500 and the benchmark most quote by the financial media. It consists of 500 publicly traded companies selected by a committee hired by the index’s owner, Stand and Poors. It is the most comprehensive of the major indexes and includes 92 percent of all publicly traded companies.
Of the 8,314 mutual funds produced by Wall Street, 73 percent are actively managed funds, which means that they have a professional manager who trades the stocks in the fund’s portfolio in order to increase its performance. The remaining 27 percent are passive index funds whose object is to mimic the performance of a specific market index. Index funds don’t trade in order to enhance their performance thus eliminate all trading cost and the expense of a fund manager.
In 2025, only 914 of all the mutual funds equaled or beat the market. Of that 914, 177 were index funds who mimic the S&P 500. Of the remaining 737 funds, only 112 made the high-performance list in 2024. All 77 S&P 500 funds were on the winners list in 2024, and the year before and the year before, and so on.
A 401k account is an investment account not a savings account. But investing is not a one size fits all proposition. Those who manage their 401k who manage their 401k wisely will get the gold. Those who take a casual approach to the management of their 401k will end up with shiny pyrite, also known as fools’ gold.
