Buying the Dip: How to Profit from Market Corrections — illustrative featured image
## The 3pm Phone Call That Cost Someone ₹4 Lakh A friend called me on a Tuesday afternoon in March 2020. The Nifty had fallen 30% in a month, and he had just sold everything. He slept well that night. Eighteen months later, he was still sitting in cash while the index ran past its old highs. The market did not reward his certainty. It punished it. That story repeats in every correction, in every market, in every currency. The mechanics of how to investing in stock market during a slide are not complicated. The hard part is doing them while your stomach is in knots. This guide is for the salaried reader in New York, Manchester or Frankfurt who watches a red screen and wonders whether to act. We will cover valuation, timing and the boring discipline that separates bargain hunters from panic sellers. ## Why Corrections Are Not Crashes A correction is a fall of 10% or more from a recent high. A bear market is 20%. The distinction matters because corrections happen roughly once a year on average in developed markets, and most of them resolve within a few months. Crashes are rarer and deeper. The Reuters headline that caught our eye recently, about Indian shares advancing on [bargain buying](/coupon/blog/black-friday-for-indian-retailers-unlock-rewards-cashback) after a slide, is a small case study in how this works. Prices fall, valuation-sensitive buyers step in, and the index stabilises. That is not a prediction. It is a pattern that has repeated for as long as exchanges have existed. What kills returns is not the fall. It is the behaviour around it. ## Valuation: The Only Anchor That Matters You cannot time the bottom. You can, however, estimate whether you are paying a fair price. Three tools do most of the work. - **Trailing P/E ratio.** Compare the index or stock against its own ten-year average, not against a single number someone quoted on television. - **Price-to-book.** Useful for banks and financials, where earnings swing wildly but book value is steadier. - **Dividend yield.** When yields on quality names creep above their long-run average, sellers are usually more desperate than the businesses are troubled. A simple test: if a stock you liked at $80 looks attractive at $55 and its earnings estimates have not changed, the correction handed you a discount. If earnings estimates have collapsed, you are catching a falling knife. ### The Earnings Check Before you buy anything in a selloff, open the most recent quarterly report. Ask one question: did revenue and margin hold up, or did the company quietly guide lower? Price falls are noise. Guidance cuts are signal. Buy the first, avoid the second until the dust settles. ## Timing: Ladder In, Do Not Lump In Nobody rings a bell at the bottom. The practical answer is to buy in tranches. If you have $10,000 earmarked for a dip, deploy it in three or four chunks over several weeks. You will never get the perfect entry, but you will avoid the regret of going all in two days before another 8% leg down. | Trigger | Action | |---|---| | Index down 10% | Deploy first tranche (25%) | | Down 15% | Deploy second tranche (25%) | | Down 20% | Deploy third tranche (25%) | | Down 25% or stabilisation | Deploy remainder | For salaried investors, [systematic monthly investing](/finance/blog/how-to-start-a-systematic-investment-plan-sip-in-mutual-funds-a-beginner-s-guide) does most of this automatically. A SIP or a recurring buy into a broad index fund keeps you buying through the fall without needing to make a decision on a bad news day. ## What to Buy, and What to Leave Alone Not everything on sale is a bargain. Some things are cheap because they deserve to be. Quality first. Companies with low debt, stable cash flow and a track record through at least one previous downturn. Index funds and broad ETFs if you do not want to pick. Large-cap leaders that fell with the market rather than because of it. Leave alone: highly leveraged businesses, cyclical stocks at the start of a downturn, and anything you cannot explain in one sentence to a friend. ## Our Take: What We Would Actually Buy We are not financial advisers, and this is not personalised advice. But if we were deploying new money into a correction today, this is the shape of it. - **Core holding: Vanguard Total World Stock ETF (VT) or iShares Core MSCI World (IWDA).** One line item, global exposure, no stock-picking required. Buy it in tranches. - **Satellite: Vanguard S&P 500 (VOO) for US-heavy exposure.** Add on 10% drawdowns, not on headlines. - **For UK and European readers: a FTSE All-World or MSCI ACWI ETF in your ISA or local equivalent.** Tax wrapper first, ticker second. - **Cash buffer: keep three to six months of expenses untouched.** The dip is not an emergency, and you should not have to sell anything to fund one. If you hold individual names, cap any single position at 5% of your portfolio. Corrections are when concentration hurts most. ## The Tax Angle Nobody Mentions Enough Losses are not always bad. In the US, you can harvest capital losses to offset gains, and up to $3,000 of ordinary income per year. In the UK, your ISA shelters gains entirely, and the annual capital gains allowance still covers most small investors. Across the EU, rules vary, but most jurisdictions allow some form of loss offset. The practical move: if you hold a loser in a taxable account and a winner you were going to sell anyway, sell both in the same tax year. The loss reduces the bill. Then, if you still believe in the loser, wait out the wash sale window (30 days in the US) and buy it back. This is the unglamorous side of bargain hunting. It is also where real money gets saved, quietly, once a year. ## The Behavioural Trap Every correction arrives with a story about why this time is different. 2008 was the banks. 2020 was a pandemic. 2022 was rates. Each felt existential. Each passed. The investors who did well were not smarter. They had a plan written down before the fall, and they followed it when it was uncomfortable. Write yours now: what percentage you will deploy at each drawdown level, which funds you will buy, and what you will not touch. Then when the next red week arrives, you read the plan instead of the news. ## FAQ **How much of my portfolio should I deploy in a correction?** Only money you will not need for at least five years. Keep three to six months of expenses in cash first. After that, deploy in tranches rather than all at once. **Is it better to wait for the bottom?** You cannot identify the bottom in advance. Waiting usually means missing the sharpest recovery days, which cluster right after the worst ones. Laddering in is the practical compromise. **Should I sell my losers to buy bargains?** Sometimes. If the thesis has broken, sell and redeploy. If it has not, and you are in a taxable account, consider harvesting the loss for tax purposes and rebuying after the wash sale window. Bargain buying is not a personality trait. It is a checklist, a calendar and a tolerance for looking wrong for a few months. The market pays for that tolerance, eventually. It rarely pays for conviction alone.
