If you're reading this in April 2026 with a portfolio that's down 15-25%, you're in a specific kind of financial pain that most investment literature doesn't adequately prepare you for.
The numbers are one thing — a paper loss, a red number on a screen. But the psychological experience is different. You watch each green day with cautious hope and each red day with growing dread. You calculate how long it'll take to "get back to even" at current loss rates. You wonder whether this time is different, whether the recovery you're counting on won't happen this time.
This psychological state is when the most expensive financial mistakes get made. Not because investors are unintelligent — but because the human brain is wired for loss aversion in a way that makes rational decision-making during drawdowns genuinely difficult.
Here is what the data says about what works.
The Most Expensive Mistake: Selling at the Bottom
The 2020 COVID crash is the cleanest recent example, because the drawdown was severe, fast, and unambiguous — and the recovery was equally dramatic.
Between February 28 and March 23, 2020, the Sensex fell 33% in 24 trading sessions. ₹45 lakh crore of market capitalisation was erased. The India VIX — the fear index — hit levels that made most investors genuinely uncertain whether markets would ever recover.
What happened to investors who sold near the bottom and went to cash?
They locked in a permanent 33% loss on the capital deployed. And then they sat in cash watching the most dramatic market recovery in Indian history unfold without them. By December 31, 2020, the Sensex was at 47,751 — above its pre-crash level. The 33% loss had not just reversed; it had been replaced by a 86% gain from the March 23 bottom.
The investors who sold near the bottom faced a compounding problem. They had already taken the pain of the drawdown. But now markets had recovered 30-40% from where they sold, and buying back in felt like "chasing" at elevated prices. Many never re-entered. They locked in the loss permanently and missed the entire recovery.
This is not a fringe outcome. AMFI data from 2020 shows that SIP cancellations and redemptions from equity mutual funds spiked sharply in March 2020 — precisely at the bottom. The retail investor who most needed to hold (or buy) was most likely to sell.
Why the Brain Does This — and Why It's Hard to Override
Loss aversion is a well-documented cognitive bias. The psychological pain of a ₹1 lakh loss is approximately twice as intense as the pleasure of a ₹1 lakh gain. This asymmetry made evolutionary sense — losing food in a hunter-gatherer environment was more immediately threatening than gaining food was beneficial. But in financial markets, it works against you.
When your portfolio falls 20%, the emotional response is proportional to the cumulative pain of losses, not the rational assessment of what the portfolio is actually worth. Your brain interprets the sustained drawdown as a signal that things are getting worse and will continue to get worse — which triggers the fight-or-flight response, which manifests as the urge to sell and stop the bleeding.
The cruel irony is that this urge is strongest precisely at market bottoms. The pain peaks when prices are lowest — which is also when selling does the most long-term damage.
This isn't a character flaw. It's biology. Understanding this doesn't make the feeling go away, but it gives you a rational counter-argument to apply when the urge strikes.
The Three Questions to Ask Before You Do Anything
Before making any portfolio decision during a drawdown, run through these questions.
Question 1: Has the underlying business fundamentally changed?
If you hold SBI and the stock is down 20% because FPIs are fleeing Indian equities due to an oil shock, ask yourself: has SBI's loan book quality deteriorated? Has its management changed? Has a fundamental reason emerged to believe the bank will not recover?
If the answer is no — if the only reason the stock is down is macro fear rather than company-specific deterioration — then you don't have a fundamental reason to sell. You have an emotional one.
This question forces you to separate macro noise from business-specific signal.
Question 2: Are you selling because of facts or fear?
"The market feels like it's going to keep falling" is fear, not a fact. "The company's Q4 results showed a 40% drop in revenue guidance" is a fact.
Fear-driven selling and fact-driven selling produce identical decisions in the moment but very different long-term outcomes. Only one of them is rational. Making this distinction explicit — writing it down if you need to — helps interrupt the automatic panic-sell impulse.
Question 3: Do you have a plan to buy back in?
If you sell, you need to buy back eventually (unless you're permanently exiting equities, which is a different decision with different implications). At what price? On what conditions? Most people who sell in a panic don't have an answer. And without a specific re-entry plan, "temporary" cash positions become permanent.
If you can't articulate when you'd re-enter, that's a sign the sell decision is driven by emotion rather than strategy.
What Good Investors Actually Do During Drawdowns
They keep SIPs running. Every SIP unit you buy during a 20% drawdown is bought at a 20% discount to where you were before. The investors who kept SIPs running through March 2020 bought Nifty index units at 7,500-8,000. Those same units were at 14,000 by January 2021. The drawdown was a gift for disciplined SIP investors, not a catastrophe.
They rebalance, not exit. If you entered the year with 70% equity and 30% debt, and equities have fallen 20%, your allocation is now closer to 62% equity and 38% debt. Rebalancing back to 70/30 means buying more equity at lower prices. This is the counterintuitive-but-correct move that few retail investors make.
They look at individual positions with fresh eyes. A 20% broad market decline is an opportunity to evaluate each holding separately. Which stocks have fallen more than the market for company-specific reasons? Those merit review. Which have fallen simply because everything fell? Those are likely still worth holding.
They reduce speculative positions, not core holdings. If you have concentrated positions in high-PE growth stocks or mid-small caps that carry extra risk, trimming those to raise liquidity is sensible. But that's different from wholesale liquidation of your core diversified holdings.
The Number That Matters Most
In March 2020, ₹10 lakh invested in a Nifty index fund at the pre-crash level became approximately ₹6.7 lakh at the March 23 bottom — a ₹3.3 lakh paper loss.
Investors who held through the crash saw that ₹10 lakh become ₹18.6 lakh by December 31, 2020. Not ₹10 lakh recovered — ₹18.6 lakh earned.
Investors who sold at the March 23 bottom and stayed in cash through 2020 had ₹6.7 lakh. Their paper loss became a real, permanent one. And they missed an 86% gain from the bottom.
Same starting position. Same crash. Completely opposite outcomes — separated entirely by what the investor did during the drawdown.
The current drawdown is not 2020. The Iran conflict has a different character than a pandemic. But the psychological dynamics are identical, and the lesson from every prior major crash is the same: the investors who came out ahead were not those who predicted the timing correctly. They were those who did nothing, or bought, when everyone else was selling.
