What is Value Averaging?

#

Value Averaging was developed by former Harvard professor Michael E. Edleson. Instead of investing a fixed amount each period (like DCA), you aim for your portfolio's value to increase by a fixed amount.

This forces you to be a contrarian investor, automatically buying more when prices are low and less when prices are high.

VA vs. DCA: Quick Comparison

#

Real Example: VA vs DCA Side-by-Side

#

Goal: Grow portfolio by $1,000/quarter. Starting with $1,000.

The key insight: In Q3 when prices dropped, VA forced a larger investment. In Q4 when prices recovered, VA actually sold $125, locking in gains automatically.

Notice how VA invests more when prices dip (Q3) and sells when prices rise (Q4). That's "buy low, sell high" on autopilot.

Is VA Right for You?

Getting Started: 5 Steps

#

1. Define your value path - How much should your portfolio grow each period?
2. Choose your investment - Low-cost index fund or ETF
3. Make your first investment - Get on the path
4. Schedule check-ins - Monthly or quarterly reviews
5. Maintain a cash reserve - You'll need it for market dips

Bottom Line

#

Value Averaging is a powerful strategy that mathematically enforces "buy low, sell high." It can outperform DCA, but requires more effort and a cash buffer.

It was during the second week of the COVID crash. Everything was red, every headline screamed catastrophe, and I convinced myself I was being "prudent" by taking some money off the table. I sold at roughly 30% below the January high. The market bottomed nine days later. By August it had recovered the entire drop. By the end of 2021 it was 60% above where I sold.

That single decision left a meaningful chunk of what should have been a much larger position on the table. It wasn't a position-sizing mistake. It wasn't a thesis error. It was a noise mistake. I traded on what I was hearing instead of what I'd planned. A fair amount of time inside corporate finance and I still made the rookie move.

This is the article I'd send to my younger self.

Why noise feels so loud

#

Financial media is in the engagement business. CNBC doesn't make money when you don't watch. Bloomberg doesn't sell more terminals when markets are quiet. The X algorithm doesn't surface "the market did basically nothing today" because nobody clicks on it.

So the volume on bad news gets turned up, all the time. A perfectly normal correction gets called a CRASH. A 3% pullback after a 40% rally becomes BREAKING.

Add social media to the mix and you get amplification on top of selection bias. The people loudest about their predictions on X aren't the people quietly compounding into wealth. They're the people who need the dopamine of being right, or the engagement of being wrong loudly.

The asymmetry is brutal: fear is a stronger behavioural signal than greed by a factor of about 2 to 1 in the research. So the same volume of bad news hits you twice as hard as the same volume of good news. That's why a single screaming headline can undo six months of carefully built investing discipline.

The cost of trading on noise

#

DALBAR has been running an annual study since the 1990s called the Quantitative Analysis of Investor Behavior. The finding is depressingly consistent: individual investors underperform the funds they own by 1.5% to 3% annually. Not because they pick bad funds. Because they trade in and out of good ones at the wrong times.

Think about what that compounds to over a 30-year horizon. A 2% drag, compounded annually, halves your terminal wealth. That's not a rounding error. That's the difference between retiring at 55 and retiring at 70.

The behavioural gap isn't because individual investors are stupid. It's because they're listening. The pros aren't necessarily smarter. They're structurally insulated: institutional mandates, rebalancing rules, written investment policies they're required to follow.

You don't have those guardrails by default. You have to build them yourself.

What I do instead

#

Five rules. Written down. I read them when I feel the urge to do something stupid.

1. Auto-deposit, no exceptions. A fixed amount goes from my checking account into my brokerage on the 1st and 15th of every month. It buys whatever my allocation says I'm underweight in. No decision required, no chance for cleverness.

2. No news between 9am and 4pm Dubai time. This covers the entire US market open. I don't watch CNBC. I don't refresh Yahoo Finance. I don't have the brokerage app on my phone's home screen. If I want to know how my portfolio did this week, I find out on Saturday morning when nothing is open.

3. Quarterly review, not daily. I look at the actual numbers four times a year. I rebalance once. The other 361 days, I'm not allowed to make allocation changes.

4. Written investment policy. Three pages. What I own, why I own it, what would have to be true for me to change. The discipline isn't in the document itself. It's in the requirement to re-read the document before making any decision. By the time I'm done reading it, the impulse usually passes.

5. No leverage on the long-term portfolio. Margin and options are fine as active income overlays in a separate account. The long-term FIRE portfolio stays unleveraged. This means I'm never forced to sell at the bottom. That's a luxury I bought with discipline.

For the mechanics of DCA itself, see DCA Dollar Cost Averaging. The rules above are what make DCA actually work.

The "do nothing" power

#

The single best investing decision I've ever made wasn't a buy or a sell. It was the period from 2008 to 2013 when I did nothing. I auto-deposited into broad index funds every month. I didn't sell during the 2008 crash. I didn't pause contributions when the headlines said the world was ending. I didn't try to time the bottom.

Those five years of doing nothing produced more lifetime wealth than the next ten years of actively managing things did. The reason isn't mysterious: I bought when nobody else wanted to buy, and I let compounding work.

This is the cheat code. The market isn't trying to outsmart you. It's trying to scare you. The discipline to stay in your seat, especially when everything in the news is telling you not to, is worth more than any stock-picking edge you'll ever develop.

The Rule

#

If you can't follow the rules above, follow this one: every time you feel the urge to react to a headline, ask yourself a single question. "Have I had this thought before? What happened the last time I acted on it?"

If you're honest, the answer will usually be: it cost me money.

That's the lesson. The noise will not stop. Your job is to.

Have fun exploring.

Whether or not you should use dollar-cost averaging depends on your individual circumstances and financial goals.

How Dollar Cost Averaging Works in Practice

#

Different Variations of DCA

#

There are several variations of dollar cost averaging that investors may consider:

Rebalancing Your Portfolio

#

Because asset prices fluctuate over time, the proportion of each asset in your portfolio may change as a result of DCA.

Example: If one asset increases significantly in price, it may make up a larger portion of your portfolio, while other assets shrink. This can make your portfolio unbalanced and potentially riskier than intended.

Quick Summary

#

Conclusion: Should You Use DCA?

#

Whether or not to use dollar-cost averaging is a decision based on your individual financial goals and risk tolerance.

It can be a useful strategy for many investors, but it may not be the best option for everyone. Carefully consider the potential benefits and drawbacks before deciding.
