UPDATED 3/1/24
I am posting this here because it almost fits the theme and am aching to tell this story because it may prove valuable to other AAIIers.
I am one of those people who is never satisfied with my portfolio ... even when it is producing better results than I expected.
In his annual rebalancing articles, our own Charles Rotblut shares the details of his portfolio and uses it to reinforce the value of rebalancing. Maybe Charles' need to rebalance is the same itch I have with my portfolio, but I expand my definition of rebalancing to include improving the alpha (asset) and beta (market) covariances through portfolio additions and deletions.
I will not bury the lede (yep it is not "lead" in the newspaper business and oddly enough the printing business was founded using "lead" type.)).
Charles' "minimalist" portfolio of only 5 Vanguard index funds impelled me on a journey around the internet where I learned a lot about diversification and tracking error.
Step 1 Last October (10/23) in his post "," I noticed that Charles' retirement portfolio uses only a 4-5 indexed mutual funds (because it's a 403(a) retirement account). All the funds came from Vanguard, and he used basic allocation and diversification schemes.
Step 2 I went to vanguard.com to get data on the 4-5 index funds Charles uses as my base case/role model prototype/strawman to "rebalance" my portfolio (which by my definition is a more expansive "design" process).
At vangurad.com, I saw a lot of low-cost under 0.07 ER (or 7$ per $1,000 AUM), high-AUM (over $1B, higher the better), high liquidity (volume of transactions per trading day) ETFs – rather than actively managed index funds like Charles uses-- for each of Charles' holdings.
I also saw many other candidates that could help me reinforce/improve diversification and lower portfolio risks. I came away thinking Vanguard offerings are very cool!
Step 3 That led me to the bogleheads.com website. Wow! Those folks know how to party! And they know their stuff. They get the data on what they buy and share it openly. Lots of opinions, most supported by data. They are insular. They are Ravid Vanguard advocates. I learned a lot here. Got some significant leads (not lede).
Step 4 In several bogleheads.com comments, I saw links to the whitecoatinvesor.com website. There, I found a list of over 200 possible portfolios using mostly (>90%) Vanguard ETFs.
The sample portfolios start with only a single ETF, the Vanguard US Total Market ETF.
Then 2 ETFs - #1 + the Vanguard Ex-US Total Market ETF in a 60%/40% configuration.
From that primary geographical world markets division, an increasing number of portfolio possibilities expand the diversification theme using 3, then 4, then 5 ETFs up to around 20 total. Each addition added more "depth" to the quest for diversification incrementally increasing "slicing and dicing" the basic portfolio dimension of stocks and bonds, then adding additional diversification dimensions for stocks – geography US vs Ex-US, capitalization (Large cap, Small cap, then Mid cap), style/factor (Value vs Growth) and for expanding bonds (short, mid, and long term), adding real estate (REITs), and commodities (gold, precious minerals).
Along this journey through a modern Wonderland, I learned the pros and cons of each diversification option. You can stop at whatever level of diversification fits your risk profile and ability to deal with complexity. This tutorial taught me a lot and spurred me to seek more information on how to discriminate among these options to allocate my funds to achieve my low-cost, high-liquidity portfolio objectives.
Step 5 I kept coming across references to a book, "The Four Pillars of Investing" (2010) by William Berstein. I was familiar with another Berstein book, "Capital Ideas" (2005) which traces the implementation of modern portfolio theory (MPT). "CI" introduced me to the contributions of 20 or so MPT lead implementers who built the finance industry, which is newer than you think. MPT turns 50 in 2026.) Key pivot points for the finance industry were the 1972-1974 bear market drawdown, the 1976 invention of index funds, the 1987 flash crash, the 1998 LTCM bankruptcy, the 2000 dot.com technology bubble, and the 2008-2009 great recession. This litany makes me want to compute the "mean time between failure" rate to estimate the next "failure." Knowing this statistic would be a significant input for planning any portfolio to improve its "anti-fragility." (Coming soon.)
Step 6 I had previously read "In Pursuit of the Perfect Portfolio," (2021) by Andrew Lo of MIT and Stephen Foerster. It parallels Bernstein's chronology, but "PPF" focuses on the 10 or so Nobel Laureate academics + 2 key practitioners (Bogel and Ellis) that developed the theories that generated the math (mean-variance optimization) and principles (diversification, etc.) MPT is built on. These brainiacs planted the seeds for MPT in the 1950s and 1960s, but it took about 25 years for the "professional" financial industry to embrace MPT as its mantra.
Step 7 I was starting to see a systematic way to "rebalance" my portfolio and to position it to accommodate the sociological, technological, economic, environmental, and political ("STEEP") forces that will inevitably impact markets as they have done frequently in the past. (That reminds me that I need to get that MTBF statistic.)
Step 8 The whole time I am "surfing the net" (Suddenly, I hear Brain Wilson, Mike Love, and The Beach Boys singing "Catch a Wave" (and you're sitting on top of the world") from 1964).
Step 9. I am also staying current on AAII.com through updates from the Premium programs. AAII screens implement portions of MPT through The Model Shadow Stock portfolio (MSSP) Coonan started the 55 or so "guru" screens that each relies on fundamental financial analysis (FA), technical analysis (TA), or "factors" theory which can be used to "tilt" (raise, lower, or balance) portfolio diversification to try to capture specific market "anomalies," that have proven to increase "equity premiums," e.g., (1) size/market cap/valuation, (2) value/low price, (3) growth/momentum, etc., or to "spread" portfolio risks (alpha (asset variation/risk), beta (market variation), PF to BM error tracking variation), etc. which begins with mean-variance optimization to allocate portfolio assets to the "mix" of expected returns and risks you can tolerate.
Step 10 After I revisited these MPT principles, I returned to vanguard.com (and schw.com and fidelity.com my other brokerage sites) to identify, select, and compare ETFs using the criteria listed in Step 2.
Step 11 The denouement. This "bundle" of step-wise analyses generated a portfolio "rebalanced" (tweaked) that it is conservative due to my goal of capital preservation with moderate growth implemented to achieve goals of 15% return on equities and 5.5% return on fixed income (money market funds) growth for 2024
Step 12 "The Hero of a Thousand Faces" returns home. "The Hero with a Thousand Faces" (1949) by Joseph Campbell explores the common elements found in myths and stories from around the world. It proposes that all hero stories follow a similar pattern, and, by understanding this pattern, we can better understand ourselves and our place in the world. In "HTF" the hero must leave his home/tribe and find his purpose and then return home to share his "bane" with his family/tribe to find his purpose in life.
After this journey, I implemented a diversified portfolio using 9 ETFs (mostly from Vanguard).
Overall. it is designed to achieve or surpass the average prediction of a 5% market growth in 2024 (by market maker banks (JPM, GS) and large brokerage (BLK, SCHW, FID, VGD) 2024 forecasts).
I have calculated the following statistical parameters for the portfolio.

Performance as of this update (@2/29/24) = 5.43%.
The point of this odyssey is that it all started with Charles sharing this portfolio information. Sometimes what you are searching for is right under your nose. Ask Odysseus/Ulysses, the Greek hero in Homer's Iliad famed for his intellect and cunning. He created the plan to sack the city of Troy using the "Trojan Horse." He is also famous for his long odyssey trying to return home after the Trojan War. After the destruction of Troy, Odysseus and his men left for home without paying proper respect to Poseidon, one of the most powerful gods in ancient Greek mythology, responsible for earthquakes, rivers, floods, droughts, and anything involving water in general. For his disrespect, Poseidon punished Odysseus with a ten-year journey home. Further insults by Odysseus against Poseidon complicated this journey. (That's an "mythical" understatement.)

Ronaldo J from IL, thanks for sharing your analysis of this article. You were very kind.
It's my turn.
After I read this article first time, I went out and read a lot of factors research papers. I needed to chew on some data to get the empty feeling this article left since there is so little data ("empty calories") here.
Jumping out of a box, yelling "Me Quant!" and giving a Tarzan yell hardly convinces me you know what you are doing.
"Quant" as described here, is a redux of the same argument in the classic 1980's "Reese's Peanut Butter Cup" commercial -- you can have BOTH peanut butter (value) and chocolate (momentum) in one candy. My problem is: for a "quant," I do not see a lot of meat and potatoes data here; only empty calories and "dead air" space where data should be.
No (as in zero) data on performance or outcomes.
Two graphs with "hypothetical" ("just so") data.
He argues that quants perform better than average – and provides zero data to support that -- because they have one foot on a block of ice (value factor) and one in a fire (momentum factor) and thus everything is "comfortable' on average.
Again, no side-by-side comparison data.
I do see a lot of unsupported "condescended assertions" wrapped in a lot of pretty "just so" faux MPT speak – beta, variance, covariance, diversification, etc. (implied, but again no data).
I see a lot of illusions to "factors theory" but only one source Fama. Even there, he offers no Fama citations, no data, no examples to support his assertions.
There is a lot of research on factors theory (currently there are over 200 factors that disagree with these assertions. Each with a quant bigot standing on ice and in fire and doing a Tarzan yell)
Most of what passes the smell test for data is hinted at in Charles' "lead the witness" (Ham Burger style, Perry Mason's DA arch foil) questions.
Charles, invite him back and ask him back and ask him to bring data.
PS, Charles, I am pretty sure AAII has 20-30 years of data in the MSSP, factor (Growth Investing), and guru screens (ALL are based on different factors) to help us see how tasty this Peanut Butter Cup is. Me? I'm more of an almond M&M's type - fat value in the middle wrapped in sweet caloric momentum on the outside ... with red table wine of course.
I am filing this one in the "ignore the financial press" folder like William Berstein repeatedly recommends in "The Four Pillars of Investing," (2101).

Hi Everyone,
Considering Dan Villalon's assertion in this article that blending momentum and value strategies may yield superior returns, what challenges or suggestions have you encountered when integrating momentum with value?
Looking forward to hearing everyone's thoughts on this combo strategy. Thank you!
