Why a Small Loss Can Create a Permanent Gap
How compounding works for you — or against you
Bryan Daly, CFP®, RICP®
Objective
Help advisers show clients how even a small one-time loss has long-term consequences — and why protecting the downside is more powerful than chasing higher returns.
Key messages
The hook: “If your portfolio drops 5%, how much do you need to gain to get back to even?” Most clients say 5% — the answer is about 5.26%. Now extend that thinking over decades.
Compounding works both ways. Michelle’s money doubled every 10 years because it stayed invested and never went backward. Bill’s compounding was interrupted by one small loss, so all future growth compounded on less principal — a permanent compounding gap.
Once you lose time or principal, you can’t “recompound” it. You can’t average your way back — you must compound your way back, and that takes time you don’t get back.
Sequence of returns risk: in retirement, withdrawals magnify the impact of losses. A 10% loss early in retirement can erase years of income potential.
The story of Michelle and Bill
| Michelle | Bill | |
|---|---|---|
| Starting balance | $100,000 | $100,000 |
| Annual return | 7.2% for 10 yrs | 7.2% for 9 yrs + one 5% loss |
| After 10 years | $200,000 | $165,700 |
| After 20 years | $400,000 | $331,400 |
| After 30 years | $800,000 | $662,800 |
Bill ends up with less than Michelle because of just one 5% loss — the timing and sequence of returns interrupted his compounding.
The math behind recovery
| Loss | Gain needed to recover |
|---|---|
| 10% | 11.1% |
| 20% | 25.0% |
| 30% | 42.9% |
| 40% | 66.7% |
| 50% | 100.0% |
Each additional 10% loss increases the recovery requirement disproportionately.
Why it matters for advisers
- ◆Show why risk management and principal protection matter more than chasing returns.
- ◆Introduce strategies that minimize or eliminate negative years — fixed indexed annuities, buffered ETFs, downside protection strategies.
- ◆Frame the conversation around consistency, not excitement: “You don’t have to hit home runs — you just can’t strike out.” Protection is the new alpha.
- ◆Reinforce the difference between rate of return and sequence of returns — and communicate it clearly.
Practical takeaways
During market volatility
- Show clients why staying protected or rebalanced matters more than chasing rebounds.
When discussing product solutions
- Illustrate why downside protection has value — it prevents permanent compounding damage.
Behavioral framing
- Losses hurt about twice as much as gains feel good. That’s why clients panic — unless they’re protected.
Workshop exercise
- If a client’s portfolio dropped 30% in 2020, what return would they need to get back to even — and how many years at a 7% average?
“Answer: a 42.9% gain — over 5 years just to break even.”
Scripts to use with clients
“You don’t need the highest returns to win. You need consistent returns without major setbacks. One small loss early in retirement can create a gap you can never close. Our goal is to make sure you’re Michelle — not Bill.”
“Most people think if they lose 20%, they just need 20% to get back to even. But that’s not true — they need 25%. If they lose 40%, they need 67% just to break even. That’s why our strategy isn’t about chasing the biggest gains — it’s about avoiding the biggest losses.”
Team discussion questions
- How can we demonstrate this concept using our client’s actual portfolio history?
- What products or strategies in our toolbox help reduce the chance of a “Bill year”?
- How can we reframe client conversations from “What’s my return?” to “How stable is my compounding?”
