Volatility is a feature of Indian equity markets, but sharp weekly moves of 2–3% in the Nifty 50 can unsettle even experienced retail investors. With retail participation at record highs and demat accounts crossing 200 million as of late 2025, avoiding behavioural mistakes is critical for protecting long-term wealth. Below are five common errors investors make during market turbulence.
-
Panic-Stopping SIPs
-
-
- When the market dips, the instinct is to sell and wait for things to settle before buying again. This behaviour often proves counterproductive, as it locks in losses instead of allowing portfolios time to recover. Historically, investors who continued their Systematic Investment Plans (SIPs) through volatile periods such as the 2020 crash or the 2022 rate hike cycle benefited from rupee cost averaging.
- The Data: Stopping an SIP during a 10% market correction can reduce your 10-year terminal wealth by nearly 15–20% due to the loss of “cheap” units accumulated during the dip.

-
Revenge Trading in F&O
-
-
- New investors often try to “make back” spot market losses by pivoting to Futures & Options (F&O). This is a high-risk gamble.
- The Data: SEBI’s landmark study revealed that 9 out of 10 individual traders in the equity F&O segment incurred net losses, with an average loss of ₹1.1 Lakh per person. Volatility expands option premiums, making “guessing the bottom” an expensive mistake.
-
-
Ignoring the “Cash is King” Rule
-
-
- Many new investors remain 100% deployed at all times. Without a cash buffer, you cannot capitalize on “discounts” during a correction.
- The Quantitative Fix: Maintaining a 5–10% cash/liquid fund tactical allocation allows you to deploy capital when the Nifty P/E ratio drops below its 10-year average (historically around 20x–22x), offering better Margin of Safety.
-
-
Over-Concentration in Small-Caps
-
-
- During bull runs, small-caps offer multi-bagger returns, but they are the hardest hit during volatility.
- The Data: In a standard market correction, Small-cap indices often see drawdowns of 25–30%, while the Nifty 50 might only drop 10–12%. Over-leveraging in small-cap stocks without a Large-cap “anchor” leads to portfolio wipeouts.
-
-
Anchoring to “All-Time Highs”
-
- New investors often refuse to sell a non-performing stock because they are waiting for it to return to its peak price. In a volatile market, some stocks may never recover to those levels.
- The Strategy: Instead of price anchoring, focus on earnings growth. If a company’s EPS (Earnings Per Share) is declining while volatility is increasing, holding on is a “sunk cost” fallacy.
Frequently Asked Questions
- Why should investors avoid stopping SIPs during market volatility?
Stopping SIPs during a market dip can reduce long-term returns because investors miss the opportunity to buy units at lower prices. - Why is revenge trading in F&O risky?
Futures and Options are highly volatile, and many retail traders lose money trying to recover losses quickly through risky trades. - Why is keeping some cash important for investors?
A cash reserve allows investors to buy quality stocks or funds at lower prices during market corrections. - Why is over-investing in small-cap stocks risky?
Small-cap stocks can fall much more during market corrections, which can lead to larger portfolio losses if not balanced with large-cap investments.
