Underwater Positions and Time
An underwater position is any investment worth less than you paid for it. A stock purchased at $100 that's now trading at $60 is underwater by $40 per share, or 40%. The mathematical problem: recovering from a 40% loss requires a 67% gain on the depressed price to break even. The time problem: that recovery happens on a smaller compounding base, extending the period before the position contributes positively to wealth again. Underwater positions don't just cost you the decline—they cost you compounding time on a permanently reduced capital base.
Quick definition: An underwater position is an investment worth less than its purchase price, requiring a percentage gain greater than the initial loss percentage to achieve break-even, with the additional burden that recovery compounds on a smaller base.
Key takeaways
- A 50% loss requires exactly 100% gains to break even ($100 → $50 → $100), a mathematical asymmetry built into all underwater positions
- Each loss percentage increases the required recovery percentage: −20% needs +25%, −30% needs +43%, −40% needs +67%, −50% needs +100%
- Recovery is not linear; gains on a smaller base accumulate slower, extending break-even from years to decades for severe losses
- Time adds insult: an underwater position prevents compound growth on that capital during the recovery period, creating permanent opportunity cost
- Psychological underwater effects (holding losers waiting for recovery, reducing risk-taking elsewhere) compound the mathematical damage
The Math of Underwater Recovery
The relationship between loss percentage and required recovery percentage is the core of understanding underwater damage.
The formula: Recovery percentage = (1 ÷ (1 − loss %)) − 1
Examples:
- Loss: −10% → Recovery needed: +11.1%
- Loss: −20% → Recovery needed: +25%
- Loss: −30% → Recovery needed: +42.9%
- Loss: −40% → Recovery needed: +66.7%
- Loss: −50% → Recovery needed: +100%
- Loss: −60% → Recovery needed: +150%
- Loss: −70% → Recovery needed: +233%
- Loss: −80% → Recovery needed: +400%
- Loss: −90% → Recovery needed: +900%
The pattern is brutal: losses become increasingly difficult to recover from as they deepen. A 30% loss seems manageable (only needs 43% recovery), but a 50% loss requires doubling the entire investment. A 70% loss requires tripling it.
Why the asymmetry exists: When you lose 50%, you're left with half your capital. Doubling $50,000 requires earning $50,000 in returns. That's not a 50% return on the remaining capital—it's a 100% return. The denominator shrinks, making percentage gains exponentially harder.
This is negative compounding in its purest form: the base shrinks, so gains compound from a smaller foundation. An investor underwater on a position is compounding at a slower absolute rate, even if percentage returns are identical.
Time Cost: The Recovery Timeline
Beyond the mathematical recovery percentage, underwater positions impose a time cost that compounds the damage.
Scenario: Stock purchased at $100, falls to $50 (50% loss)
To break even at various expected return rates:
- 5% annual returns: Recovery takes 14.2 years
- 7% annual returns: Recovery takes 10.2 years
- 10% annual returns: Recovery takes 7.3 years
- 15% annual returns: Recovery takes 5.0 years
- 20% annual returns: Recovery takes 3.8 years
The comparison is stark: what's presented as "just needing a 100% gain" actually translates to a decade of waiting at normal market returns before the position breaks even.
But the time cost extends further. During those 10 years (at 7% returns), what could have been earned on fresh capital?
Comparison: Investor A (holds underwater stock) vs. Investor B (cuts loss, invests fresh capital)
Both started with $100,000, and both have 10-year horizons.
Investor A:
- Bought stock at $100/share, owns 1,000 shares
- Stock falls 50% to $50/share; position worth $50,000
- Holds for recovery at 7% annual returns
- After 10 years: Position worth $100,000 (just breakeven)
- No additional capital deployed; only the original $100,000 compounds
Investor B:
- Same initial stock purchase: 1,000 shares at $100 = $100,000
- Stock falls 50% to $50/share; position worth $50,000
- Sells at $50 (realizes loss)
- Takes that $50,000 loss as a tax deduction (saves $12,500 in taxes if 25% bracket)
- Invests $50,000 in diversified index fund expected to return 8% annualized
- Keeps original $50,000 for ongoing contributions
- After 10 years:
- Original $50,000 remains in cash/savings (conservative)
- Index investment worth: $50,000 × 1.08^10 = $108,000
- Total: $158,000
The difference: Investor B has $158,000 vs. Investor A's $100,000—$58,000 ahead, despite both experiencing the same initial 50% loss on the stock. The difference came from (1) harvesting the loss for tax benefit, (2) redeploy into diversified assets, and (3) no longer waiting for recovery.
This illustrates the true cost of underwater positions: not just the loss itself, but the decade of capital tied up waiting for recovery, during which that capital could have been compounding elsewhere.
Real-World Example: The 2000–2010 Underwater Positions
Investors who bought technology stocks in 1999–2000 at peak valuations faced underwater positions that lasted a decade.
Cisco Systems example:
- Peak price: $82.04 per share (March 2000)
- Trough price: $8.59 per share (October 2002)
- Loss: 89.5%
- Recovery needed: 844% gain
Someone who bought 1,000 shares at $82 for $82,000 saw their position fall to $8,590 by 2002. To break even:
- At 8,590 × 844% = $82,000 break-even
- Required Cisco to rise to $73/share (just to break even, not profit)
- Cisco didn't reach $73 until 2007—7 years later
During those 7 years:
- Investor held underwater position, unable to move capital elsewhere
- Dividends were minimal (tech stocks paid little)
- Opportunity cost was massive (S&P 500 returned ~15% annualized during 2003–2007)
An investor who cut their loss in 2002 and invested $8,590 in an S&P 500 index fund would have had $16,000+ by 2007 (with the recovery bounce included). Instead, they had exactly $8,590 to $10,000 waiting for Cisco to recover.
This pattern repeated across tech stocks:
- Yahoo: From $237 (peak) to $2 (trough), required 11,750% gain to recover
- Nortel: From $124 to essentially $0 (bankruptcy)
- AOL: Similar destruction
For investors holding these, the mathematics of underwater positions combined with years of negative compounding created permanent wealth destruction.
Psychological Underwater Effects
The numerical recovery requirement is only part of the damage. Underwater positions create psychological effects that compound the loss further.
The holding behavior: Investors holding underwater positions often exhibit "hold until recovery" behavior. They mentally partition the loss as "temporary" and wait for recovery to break even. This delays redeployment of capital and reduces overall returns.
The reduced risk-taking: An investor with an underwater position often becomes risk-averse elsewhere, paradoxically. Having experienced loss on one position, they reduce risk-taking elsewhere, accepting lower returns overall. This compounds the recovery damage.
The confirmation bias: Underwater positions create confirmation bias. The investor looks for positive news on the position and ignores negative news. They convince themselves recovery is imminent, which extends the holding period beyond rational analysis.
The tax-loss avoidance: U.S. tax law allows harvesting losses to offset other gains, saving taxes. But investors often hold underwater positions specifically to avoid "locking in the loss." This irrational tax dread costs more in lost compound growth than the tax benefit is worth.
Example: An investor holds an underwater position worth $30,000 (originally $100,000) to avoid recognizing the $70,000 loss. They think: "If I realize the loss, I admit failure." Meanwhile, that $30,000 could have been redeployed to compound elsewhere. Even if the new investment returns just 8% annually, it will grow to $65,000 in 10 years, while the underwater position requires a 233% gain (to recover the 70% loss) plus additional gains to profit. In most cases, redeploy beats holding.
The Catch-Up Problem for Severe Losses
The deeper the underwater position, the more difficult catch-up becomes, even with normal market returns.
Example: 70% loss
- Initial investment: $100,000
- Current value: $30,000
- Recovery required: 233% gain
- At 7% annual returns: Recovery takes 14.9 years
- At 10% annual returns: Recovery takes 10.5 years
During that decade of recovery, the investor:
- Has no capital gains (only compounding toward break-even)
- Cannot withdraw income from the position without extending recovery further
- Faces opportunity cost of deploying that $30,000 elsewhere
The compound effect: after 10 years of holding, the investor breaks even on the original $100,000 but has sacrificed the $100,000 that could have been deployed elsewhere and compounded at 8–10% to become $215,000–$260,000.
The true cost of a 70% loss with 10-year recovery period: $115,000–$160,000 in lost compound growth, not just the initial $70,000 loss.
The Role of Time Horizon
Time horizon determines whether holding underwater positions is rational or irrational.
Long time horizon (20+ years): For underwater positions in good companies, a 20-year horizon might allow recovery and subsequent appreciation. General Electric fell 75% from $60 (2007) to $15 (2009), but reached $45 by 2017 with 20-year horizon holders. They experienced 15 years of underwater pain but eventually profited.
Medium time horizon (5–10 years): Medium time horizons often mean underwater positions don't recover in time. An investor with a 10-year horizon holding a 50% underwater position will spend most of that decade waiting for break-even, then have only 2–3 years for actual growth beyond break-even. This is inefficient capital allocation.
Short time horizon (<5 years): For short time horizons, holding underwater positions is almost always irrational. The capital is too needed for growth elsewhere. Selling at a loss and redeploy is nearly always superior.
The calculation should always be: "What's the expected return on this underwater position over my time horizon, compared to the expected return on the next best investment?" If the next best investment has higher expected returns, hold the next best. The underwater position's past is irrelevant.
Sector Effects: Some Underwater Positions Never Recover
Not all underwater positions eventually recover. Some sectors and companies face permanent decline.
Kodak example:
- Peaked at $94/share (1997)
- Fell to $0 via bankruptcy (2012)
- Investors who bought at peak and held experienced 100% loss
- Recovery was impossible
- A decade of holding produced nothing
Lehman Brothers:
- Shareholders lost 100%
- Employees' 401(k)s with Lehman stock lost everything
- No recovery was possible
Blockbuster:
- Fell from $30 (2000) to bankruptcy
- Customers who held saw permanent loss
The data: about 20–30% of companies that decline 50%+ never fully recover. They either:
- Go bankrupt (permanent 100% loss)
- Experience sector decline (permanent loss due to structural change)
- Become zombie companies with perpetual losses
For investors in these companies, the underwater position wasn't temporary—it was a permanent capital loss. Holding rather than harvesting the loss for tax deductions cost them tens of thousands in lost alternative compounding.
Tax-Loss Harvesting as Underwater Management
The primary advantage of acknowledging underwater positions is tax-loss harvesting: the ability to offset other gains and deductions with realized losses.
Example:
- Investor has a $50,000 gain from selling Apple shares
- Investor has a $50,000 underwater position in an individual stock
- Sell the underwater position, realizing the $50,000 loss
- Net gain for the year: $0 (offset the Apple gains)
- Tax savings: ~$12,500 (at 25% bracket)
- Redeploy the $50,000 into diversified index fund
The calculation:
- Apple gain: $50,000
- Underwater position loss: −$50,000
- Net gain: $0
- Tax payable: $0 (instead of ~$12,500)
- Underwater position redeployed: $50,000 into index fund at 8% returns
- After 10 years: $50,000 becomes $108,000
The $12,500 tax savings, compounded at 8% for 10 years, becomes $27,000. Combined with the $108,000 growth, the investor has $135,000 from the $50,000 redeployment—versus potentially holding underwater for 10 years waiting for recovery.
Tax-loss harvesting acknowledges that underwater positions are more valuable as tax deductions than as recovery bets.

Common Mistakes with Underwater Positions
Mistake 1: Holding to "minimize realized losses" Holding to avoid realizing a loss is tax dread, not rational investing. A $50,000 unrealized loss becomes a $50,000 realized loss either way. The question is whether to harvest it for tax benefit or wait. Waiting sacrifices compounding opportunity.
Mistake 2: Increasing position size on underwater stocks "Averaging down" on underwater positions is often presented as a strategy. The rationale: buying more at lower prices reduces average cost basis. The risk: the position is underwater for a reason. Adding capital to a failing position increases exposure to permanent loss. Averaging down is appropriate only when the fundamental reason for the decline is temporary.
Mistake 3: Holding losers while cutting winners The opposite of holding losers is selling winners prematurely to lock in gains. Investors often hold losers waiting for recovery while selling winners to feel successful. This creates a portfolio of underwater positions and no winners—a recipe for below-market returns.
Mistake 4: Not harvesting losses for tax benefit If you hold an underwater position and have other gains, harvesting the loss is nearly always superior to holding. The tax deduction value alone often justifies the sale, and the opportunity to redeploy is a bonus.
Mistake 5: Confusing "underwater" with "bad investment" Some underwater positions are bad investments (fundamentals worsening). Others are simply in temporary drawdowns (good companies, temporary market declines). Distinguishing between the two determines whether holding or selling is rational.
FAQ
How long does it typically take to recover from underwater positions?
Depends on the loss depth and expected returns:
- 20% loss at 7% returns: 2.7 years
- 40% loss at 7% returns: 5.7 years
- 50% loss at 7% returns: 10.2 years
Most underwater positions take 3–10 years to recover, which ties up capital that could compound elsewhere.
Should I hold underwater positions indefinitely?
No. At some point, opportunity cost justifies harvesting the loss and redeploy. If 10+ years haven't seen recovery, the cost of waiting often exceeds the benefit.
Can I use underwater positions for tax planning?
Yes, via tax-loss harvesting. Realize the loss, offset other gains, and redeploy to similar (but not identical) holdings. Rules prevent buying the same security within 30 days (wash-sale rule), but you can buy similar index funds.
What's the worst-case scenario for underwater positions?
Bankruptcy. Some underwater companies go to zero (Lehman, Blockbuster). For these, there's no recovery—only permanent loss. Diversification prevents any single position from causing catastrophic damage.
Should I bail out of underwater positions during market rallies?
Often yes. If a recovery rally brings the position back to near break-even, exit and redeploy. Waiting for full recovery beyond break-even is usually suboptimal.
How do underwater positions affect retirement planning?
Significantly. If your retirement portfolio has underwater positions, you might not have sufficient capital to retire as planned. Tax-loss harvesting can help, but underwater positions should be addressed before retirement through diversification and rebalancing.
Can dividend payments help underwater positions recover?
Marginally. Dividends provide some return even as the position is underwater. But the capital appreciation recovery still requires the full percentage gain. Dividends help, but slowly.

Summary
Underwater positions—investments worth less than purchase price—impose damage beyond the initial loss. They require increasingly difficult recovery percentages as losses deepen: a 50% loss needs 100% gain, a 70% loss needs 233% gain, and so on. This asymmetry is built into compounding mathematics and is inescapable.
Beyond the math, underwater positions impose a severe time cost. An investor waiting 10 years for a 50% underwater position to recover breaks even, but meanwhile that capital could have doubled in a diversified index fund. The compound growth opportunity cost often exceeds the initial loss.
Psychological effects amplify the damage. Investors holding underwater positions exhibit hold-until-recovery bias, reduce risk-taking elsewhere, and miss tax-loss harvesting opportunities that could accelerate recovery through redeployment.
The practical solution is rarely to hold underwater positions indefinitely. Instead, harvest losses for tax benefit, redeploy to higher-conviction investments or diversified index funds, and allow that capital to compound. The mathematical reality: redeploying after a loss is typically more wealth-efficient than holding for recovery, even for positions that would eventually recover.
Underwater positions are a core mechanism of negative compounding: they reduce your capital base, extend recovery timelines, and prevent deployment of capital to higher-returning alternatives. Understanding this dynamic is essential to managing portfolio drawdowns and maintaining long-term wealth growth despite inevitable losses.
