Changing Strategy Mid-Stream
Changing Strategy Mid-Stream
In 2016, you commit to a value-focused strategy (buying cheap, profitable stocks and funds). In 2017–2019, value underperforms tech growth. You get frustrated and switch to a growth strategy. In 2020, value rebounds 30%. In 2021, you chase momentum and shift to crypto. In 2022, crypto crashes. You've now owned every winning strategy, but only after it stopped winning.
Key takeaways
- Different strategies (value, growth, momentum, quality) are in and out of favor on multi-year cycles; switching between them locks in losses and misses the recoveries
- The investor who switches strategies has owned every strategy during its worst periods—the exact opposite of good timing
- A deliberate strategy held for at least 5 years has time to recover from drawdowns and compound; strategies held for 2 years or less are whipped around by volatility
- The cost of strategy-switching is both tax (realizing losses at the worst time) and opportunity (missing the rebound in the strategy you just abandoned)
- A written plan that names your strategy and specifies the holding period is the defense against mid-stream changes
The style-rotation disaster
Consider an investor who makes active strategy choices every 2–3 years:
2015: Believes in value investing. Reads "Contrarian Investing the Templeton Way." Commits to a value strategy. Builds a portfolio of: Berkshire Hathaway (B), a value ETF (VTV), and value-focused funds. Cost: $100,000.
2016–2017: Value works. The portfolio rises to $110,000. But 2017–2018 is dominated by mega-cap tech growth (Apple, Amazon, Google). His value holdings lag. Tech investors are making 25% annual gains; his value portfolio is flat to down 5%. Frustration sets in.
2019: He hears about "momentum" and "growth at a reasonable price." He reads a book on growth investing. He decides value is "dead" or "outdated." He sells his value positions at a loss or break-even and reallocates to QQQ (Nasdaq-100 growth ETF) and a growth fund. He's now 80% growth, 20% bonds.
2020: Growth dominates. His portfolio rises to $130,000. He thinks he's a genius. But growth stocks have gotten expensive.
2021: Growth continues to rise early in the year, peaking at $145,000. He reads an article about bitcoin and cryptocurrency and becomes convinced that "the future is digital." He moves $20,000 into bitcoin futures or a crypto fund. His portfolio is now 60% growth, 20% bonds, 20% crypto.
2022: This is the disaster. Growth falls 35%, crypto crashes 65%, and bonds also fall 14% (unusual, but it happened). His portfolio falls to $85,000. In one year, he's lost $60,000 of his 2021 peak, or 41%.
2023: Humbled and panicked, he reads a newsletter about "resilient value" and quality investing. He hears that "quality stocks held up better in 2022." He sells his remaining growth positions (at a loss, after the peak) and rebuilds into a quality strategy (defensive stocks, dividend payers, low-volatility ETFs). Cost: more tax and realization of losses.
2024: Growth rebounds. The Nasdaq is up 30% for the year. His quality holdings are up 8%. He missed the rebound because he switched exactly when the previous strategy was about to recover.
Over this 10-year cycle, he owned value (which underperformed for 2 years, then recovered), growth (which outperformed for 3 years, then crashed), crypto (which crashed immediately), and quality (which he owns at the start of a growth rebound). His realized returns: maybe 3–4% annualized. A buy-and-hold diversified investor who simply held a 60/40 portfolio and rebalanced: 6–7% annualized, with less stress.
The style cycle
Investment styles (value, growth, momentum, quality, dividend, low-volatility) rotate in and out of favor on multi-year cycles. None stays on top forever. Here's a simplified view:
- 2000–2010: Value outperforms growth (tech bubble aftermath)
- 2010–2020: Growth outperforms value (tech dominance, low rates)
- 2021–2022: Value outperforms growth (rising rates, value cheapness)
- 2023–2024: Growth outperforms value (AI narrative, mega-cap dominance)
An investor who switches strategies every 2–3 years switches exactly when the previous strategy is about to reverse. This is the opposite of good market timing.
A diversified investor who holds all styles (value and growth) and rebalances annually captures the best of both: when one is down, you're buying it at a discount; when both are up, you're compounding wealth.
The cost of strategy switching
Tax cost: When you sell to switch strategies, you realize losses. If you switch from value to growth after value has fallen 15%, you lock in a 15% loss on a multi-year strategy. You could have held and recovered; instead, you sold at the trough and will now pay tax on future gains in the new strategy.
Opportunity cost: The strategy you abandoned often rebounds after a period of underperformance. Investors who sold growth in 2019 to buy value were whipped by the subsequent growth outperformance. But the growth outperformance was exactly the rebound that value investors were waiting for.
Time cost: Each strategy switch requires research, decision-making, and portfolio restructuring. You spend 20–40 hours over a year debating and implementing the change. This time is lost productivity and opportunity.
Emotional cost: The constant switching means you're chasing narratives ("value is dead," "growth is forever," "crypto is the future"). You're adopting a new strategy at the peak of enthusiasm, not at the trough where it has merit.
The rule: hold 5 years minimum
A simple rule: commit to a strategy for at least 5 years. Five years is long enough to see a full market cycle (bull market, correction, recovery, new bull market). It's long enough for the strategy to weather at least one major period of underperformance and recover.
If you commit to a value strategy and it underperforms for 2 years, you've only 3 years left in your commitment. Hang on. The rebound is often nearby.
If you commit to a growth strategy and it crashes 35%, you've suffered the loss, but you have 4–5 years to recover. Many growth crashes recover in 2–3 years. Your commitment carries you through.
But if you have a 2-year tolerance for underperformance, you'll switch strategies every 2–3 years, and you'll always miss the rebound.
Real example: the value / growth rotation of 2016–2024
From 2016 to 2018, value massively underperformed growth. An investor in September 2018 might have thought, "Value is dead. I'll switch to growth." But 2019 was great for growth, then 2020 was the pandemic, then 2021 was mega-tech. A value investor who switched in 2018 would have caught the growth outperformance of 2020–2021.
But then came 2022, when value outperformed. And 2023–2024, growth rebounded again. The investor who stayed value through 2016–2018 would have been rewarded in 2022. The investor who switched in 2018 would have been whipped around.
The moral: you don't know which cycle you're in. Staying disciplined means staying committed to the strategy you chose, not switching it based on recent performance.

Strategy consistency requires discipline. But what fuels the discipline? The ability to separate fact from emotion—to recognize when you're switching due to a rational insight and when you're simply reacting to fear or FOMO. The next mistake is letting emotions override the rules you set.
