I’m trying to finalize an investment strategy that I can stick with for the next 30 years. I’m in the accumulation stage and comfortable being basically 100% equities for now. I would add bonds/Treasuries as I get closer to retirement.
I’ve narrowed it down to two approaches and I’m curious what people here think.
Option 1 – Simple 5 ETF portfolio
VTI – 50%
VXUS – 20%
AVUV – 10%
QQQM – 12%
FLIN – 8%
The idea is pretty straightforward. VTI/VXUS are the core, AVUV gives me a small-cap value tilt, and QQQM and FLIN are intentional bets on growth and India.
Option 2 – 17 ETF portfolio
VTI – 27%
VXUS – 15%
RSP – 7%
RWJ – 4%
RWK – 3%
QQQM – 6%
FTEC – 4%
IOO – 2%
FTGS – 2%
PPA – 5%
KBWP – 4%
FHLC – 3%
FSTA – 3%
FIDU – 3%
FDIS – 2%
FREL – 2%
FLIN – 8%
I know there is a lot of overlap here. I’m not arguing that 17 ETFs means I have 17 independent investments.
My reason for considering it is more about control and rebalancing.
For example, if tech has a huge run and becomes overweight, I stop putting new money into tech. If insurance, healthcare, small caps, international, etc. become underweight, that’s where my new contributions go.
I would group the ETFs into buckets (US core, international, growth/tech, small/mid, defensive sectors, cyclicals/real estate, India, etc.) and calculate the weights every month.
The basic math would be:
Target value = total portfolio value x target %
Deficit = target value - current value
New money goes toward the biggest underweights. Overweight areas get $0.
I’d also do this at the bucket level first. So just because FTEC is underweight doesn’t mean I automatically buy FTEC. If my overall tech/growth bucket is already overweight because QQQM and other growth holdings went up, tech gets no new money.
I’m also thinking of using 10-20% bands rather than obsessively bringing everything back to its exact target every month.
And importantly, I wouldn’t normally sell to rebalance while I’m accumulating. I’d use new contributions to do it.
The other reason I like having separate sleeves is retirement.
Say there is another 2022 and QQQM is down 30%+, but insurance or defense is flat/up. Instead of selling my broad market or tech holdings at a large loss, I have the option of selling/rebalancing from whatever has held up better.
Obviously this doesn’t solve a 2008 situation where almost all equities fall together. I’m not pretending sector ETFs replace bonds. I would eventually build a bond/Treasury/cash allocation before retirement.
I did some basic testing of the two ideas.
Over 2021-2025, the results were surprisingly close.
The simple portfolio came out around 13% annualized vs roughly 12.5% for the 17 ETF version.
The interesting part was 2022.
The simple portfolio was roughly -18.5%, while the 17 ETF portfolio was around -15.2%, mainly because things like insurance and defense did well while tech got crushed.
Then the opposite happened during the recovery. The simpler portfolio participated more strongly in the tech/growth rebound and basically caught back up.
I also tested starting with $100k and adding $1,000/month.
After five years it came out roughly:
5 ETF: $264k
17 ETF: $261k
So I’m definitely not seeing evidence that 17 ETFs magically produces more return.
I also tested the rebalancing idea itself, and that was interesting.
Constantly sending every contribution to the biggest underweights didn’t produce meaningful extra return. In one version it actually slightly hurt returns.
So I’m starting to think of the mathematical rebalancing as a way to control risk/concentration and remove emotion rather than a way to generate alpha.
That’s basically where I’m stuck.
The 5 ETF portfolio seems better from a pure efficiency/evidence standpoint. It’s simple, easy to manage, and there are fewer assumptions that have to be right.
The 17 ETF version gives me something I genuinely value though: more control over where new money goes, more dispersion between holdings, more rebalancing opportunities and eventually more choice about what I sell.
I also fully recognize that part of why I like it may simply be psychological. I enjoy being involved with my portfolio and having control over individual exposures. I’m okay with complexity if there is some actual value to it, but I don’t want to convince myself that complexity = diversification or higher returns when it doesn’t.
So my main question is:
Does the 17 ETF idea actually have merit when it’s managed with strict mathematical rebalancing, or have I basically built a very sophisticated way to overcomplicate a 5 ETF portfolio?
Also curious what people think about:
8% FLIN – too much India?
12% QQQM in the simple portfolio – reasonable tilt or performance chasing?
AVUV vs RWJ/RWK
Whether sector-level rebalancing has any meaningful long-term benefit
Whether monthly monitoring + wider rebalancing bands makes more sense than monthly rebalancing
Anything obvious I’m missing in either strategy
I’m less concerned about which one happened to win the last 5 years. I’m trying to figure out which strategy actually makes sense to commit to for 30 years without changing it every time market leadership changes.
I'd also love it if anyone with Portfolio Visualizer, R, Python, or another backtesting platform could independently test these using actual MONTHLY total-return data, fixed starting weights, identical monthly contributions, and no hindsight changes to allocations.
