Why Crashes Create Opportunity

Valuation Reset

Metric	Before Crash	After 30% Crash	Implication
Nifty PE	28	19.6	Fair value
Price-to-Book	4.2	2.9	Cheaper
Dividend Yield	0.8%	1.2%	Higher income
Earnings Yield	3.6%	5.1%	Better value

Crashes reset valuations to attractive levels.

Fear Creates Mispricing

Investor Behavior	What Happens	Opportunity
Panic selling	Good stocks sold	Buy quality cheap
Margin calls	Forced liquidation	Distressed prices
Redemption pressure	Fund managers sell	Temporary mispricing
Cash hoarding	Less buying demand	Lower competition

When others sell in fear, patient buyers profit.

The Math of Investing After Crashes

₹10 Lakh Invested After Different Drops

Entry Point	Investment	5-Year Value (15% CAGR)	Return
No crash (PE 25)	₹10 L	₹20.1 L	2.0x
After -20% (PE 20)	₹10 L	₹22.5 L	2.25x
After -30% (PE 17.5)	₹10 L	₹25.4 L	2.54x
After -40% (PE 15)	₹10 L	₹29.2 L	2.92x

Deeper the crash, higher the subsequent return (assuming mean reversion).

Why 30% Crashes Are Rare Opportunities

Crash Depth	Frequency	Average 3-Year Return
-10%	Every 1-2 years	+25%
-20%	Every 3-5 years	+45%
-30%	Every 5-10 years	+70%
-40%+	Every 10-15 years	+100%+

Major crashes are rare—invest when they happen.

Risks of Lumpsum During Crash

1. Catching a Falling Knife

Scenario	Initial Drop	Further Drop	Total Drop
2008 Oct	-40%	-20% more	-52%
2020 Mar	-35%	+5% (bottom)	-35%
2022 Jun	-15%	-5% more	-19%

You might invest after a 30% drop, then it falls another 20%.

2. Recovery Time Uncertainty

Crisis Type	Typical Recovery
Technical correction	3-6 months
Economic slowdown	12-18 months
Financial crisis	24-36 months
Structural crisis	5+ years

2008 took 18 months. COVID took 5 months. Japan (1989) took 30+ years.

3. Emotional Difficulty

Stage	Your Feeling	What You Do
Initial crash	"Great opportunity!"	Plan to invest
Further decline	"Maybe wait more"	Hesitate
Continued decline	"This is different"	Don't invest
Recovery begins	"It's a dead cat bounce"	Still wait
Full recovery	"I missed it again"	Regret

Knowing intellectually and executing emotionally are different.

Strategies for Crash Investing

Strategy 1: Phased Deployment

Instead of 100% at once, deploy in tranches:

Tranche	Trigger	Amount
1	-20% from peak	25%
2	-30% from peak	25%
3	-40% from peak	25%
4	After 3 months	Remaining

Benefit: Averages your entry if market falls further.

Strategy 2: Time-Based Deployment

Month	Investment	Cumulative
1	30%	30%
2	25%	55%
3	20%	75%
4	15%	90%
5	10%	100%

Benefit: Captures recovery if market bounces quickly.

Strategy 3: Valuation-Based

Nifty PE	Action
> 25	Don't invest lumpsum
22-25	Invest 25%
18-22	Invest 50%
15-18	Invest 75%
< 15	Invest 100%

Benefit: Systematic, removes emotion.

Strategy 4: Hybrid (Best of Both)

Allocation	Strategy	Amount
50%	Immediate lumpsum	Captures quick recovery
50%	Weekly STP over 3 months	Averages if more decline

Benefit: Balanced approach for uncertain markets.

What to Buy After a Crash

Preferred Investments

Asset	Why During Crash
Large-cap index funds	Quality survives, recovers first
Flexi-cap funds	Fund manager picks best value

Dividend-paying stocks	Income while waiting

Avoid During Crash

Asset	Why Avoid
Small-caps	May not recover; many fail
Sectoral/Thematic	Sector might be permanently impaired
Leveraged products	Can wipe out before recovery
Penny stocks	Higher bankruptcy risk

Historical Case Studies

Case 1: 2008 Financial Crisis

Nifty dropped from 6,300 to 2,500 (-60%)

Investment Date	Nifty Level	₹10 L Became (by 2024)
Jan 2008 (peak)	6,300	₹38 L
Oct 2008 (-50%)	3,100	₹77 L
Mar 2009 (bottom)	2,500	₹96 L

Lesson: Even investing at the absolute bottom (nearly impossible to time), returns were exceptional.

Case 2: COVID Crash (March 2020)

Nifty dropped from 12,300 to 7,500 (-38%)

Investment Date	Nifty Level	Return by Dec 2024
Jan 2020 (pre-crash)	12,100	+105%
Mar 23, 2020 (bottom)	7,500	+220%
Apr 2020 (+10% from bottom)	8,300	+195%

Lesson: You didn't need to catch the exact bottom. Even +10% from bottom gave spectacular returns.

Case 3: 2015-16 Correction

Nifty dropped from 9,100 to 6,800 (-25%)

Investment Timing	5-Year Return
Before correction	+65%
After -15%	+90%
At bottom	+115%

Lesson: Even moderate corrections create good opportunities.

Decision Framework

Should You Invest Lumpsum After Crash?

Factor	Yes (Invest)	No (Wait/STP)
Time horizon	7+ years	< 5 years
Market PE	< 20	> 22
Your temperament	Can handle volatility	Will panic sell
Amount	< 30% of net worth	> 50% of net worth
Emergency fund	6+ months ready	Not enough

The Checklist

Before investing lumpsum after a crash:

Check	Status
Emergency fund intact?	☐
No debt pressure?	☐
7+ year horizon?	☐
Won't need money soon?	☐
Can tolerate -30% more?	☐
Investment is diversified?	☐

All checked? You're ready to invest.

Common Mistakes During Crashes

1. Waiting for the "Perfect Bottom"

Investor	Action	Outcome
A	Invested at -30%	Made 150% in 5 years
B	Waited for -50%, it came	Made 200% in 5 years
B	Waited for -50%, it didn't come	Made 0% (stayed in cash)

The perfect bottom is only visible in hindsight.

2. Going All-In on One Stock

Approach	Risk
₹10 L in single stock	Company might not recover
₹10 L in index fund	Market always recovers

Diversify, even during "obvious" opportunities.

3. Using Borrowed Money

Scenario	Outcome
Market recovers	Good returns, pay interest
Market falls 30% more	Margin call, forced sale at loss

Never leverage during crashes—you don't know the bottom.

4. Ignoring Your Timeline

Timeline	Strategy
Need money in 2 years	Don't invest in equity crash
5+ year horizon	Crash investing makes sense

A crash can take 3-5 years to recover. Invest only long-term money.

SIP vs Lumpsum During Crash

Comparison

Factor	Lumpsum	SIP
If market keeps falling	Bigger temporary loss	Averages down
If market quickly recovers	Maximum benefit	Misses early gains
Psychological ease	Harder	Easier
Historical edge	2/3 times better	1/3 times better

Recommendation

Market Drop	Strategy
-20%	50% lumpsum + 50% STP
-30%	70% lumpsum + 30% STP
-40%	80% lumpsum + 20% STP

Deeper crashes = More lumpsum bias (valuations more attractive).

Conclusion

Situation	Action
Market down 20%, PE < 22	Invest 50% lumpsum, STP rest
Market down 30%, PE < 18	Invest 70% lumpsum, STP rest
Market down 40%+, PE < 15	Invest 80%+ lumpsum
You're nervous	Use phased deployment
Short timeline (< 5 years)	Don't invest in equity

Crashes are uncomfortable but historically rewarding. The key requirements:

1. Long-term horizon (7+ years)
2. Diversified investments (index funds)
3. Emergency fund intact
4. Emotional resilience

If you have these, market crashes are opportunities, not threats.
