How to Buy Stocks During a Market Crash

Everybody knows you should buy when stocks are cheap. It is the oldest advice in investing, repeated so often it has become wallpaper. And yet, when stocks actually become cheap – when the S&P 500 is down 30% and your brokerage account looks like a crime scene – almost nobody does it. In March 2020, you could buy Apple for $57 split-adjusted. Microsoft for $135. The entire market was on clearance. And most people were selling, not buying. Not because they are stupid, but because buying stocks while the financial world is visibly on fire goes against every survival instinct humans have. Your portfolio is bleeding, the news is catastrophic, and some part of your lizard brain is convinced that this time it really is different.

It is never different. But knowing that intellectually and acting on it with real money are two completely separate skills. This post is about the second one – the practical mechanics of actually deploying capital when markets are in freefall.

Why Does Buying During a Crash Actually Work?

The math is simple, almost offensively so. During a crash, stock prices stop reflecting business value and start reflecting collective panic. Margin calls force leveraged funds to dump positions regardless of price. ETF redemptions trigger mechanical selling across the board. Algorithmic trading amplifies the moves. The result is that a company generating $5 billion in free cash flow last year – and which will generate $5 billion next year – trades at a price that implies it will never earn money again.

This happened in 2022 with Meta. The stock dropped to $90. The company was still generating over $30 billion in annual free cash flow. The market priced it as if Zuckerberg had personally set fire to the data centers. Within 18 months, the stock hit $500. Nothing magical happened to the business. The advertising revenue was always there. The fear just evaporated and the price caught up with reality.

Same pattern during the SVB crisis in March 2023. Regional bank stocks cratered across the board. Investors dumped everything with “bank” in the name, including solid institutions with zero exposure to SVB’s problems. The selling was indiscriminate – because panic does not do nuance. Panic sells first and thinks never.

Here is the core idea: a bad quarter is not a death sentence for a quality business. But the market prices it as if the current terrible conditions will last forever. This gap between temporary pain and permanent pricing is where crash-buying returns come from. You are not predicting the future. You are simply betting that a profitable business will eventually be profitable again. This is not a high bar.

How Do You Build a Crash-Buying Checklist?

Not everything that drops 40% is a bargain. Some companies crash because they deserve to crash. Hertz went bankrupt in 2020. Dozens of profitless tech SPACs from the 2021 bubble went to zero in 2022 because they had no revenue, no moat, and no reason to exist. Buying those was not brave contrarian investing. It was lighting money on fire with extra steps.

You need a filter. Here is the checklist I use, and I suggest you build something similar before the next crash, not during it. During a crash, your brain is not functioning at peak capacity. Trust me on this.

Balance sheet strength – this is non-negotiable. The company needs to survive the downturn without raising dilutive capital. Check debt-to-equity ratios (below 1.0, ideally below 0.5). Check whether cash and credit facilities cover at least two years of operating expenses. If a company needs to issue shares at crash prices just to keep the lights on, you will get diluted into irrelevance. Companies like Microsoft, Johnson & Johnson, or Costco can sit through any storm and come out the other side buying back stock at low prices. That is what you want.

Essential demand. People stop buying luxury handbags during a recession. They do not stop buying groceries, paying for electricity, using cloud infrastructure, or processing credit card payments. Companies whose revenue is driven by necessity rather than discretion have a natural floor under their earnings. The dip is shallower, the recovery is faster, and the risk of permanent loss is dramatically lower. During the 2020 crash, consumer staples and healthcare stocks recovered in months while cyclical names took years.

Pricing power. Can the company raise prices without losing customers? This is the hallmark of a truly durable business. Visa takes a percentage of every transaction – they do not care whether you are buying groceries or jewelry. A dominant cloud provider whose software is deeply embedded in enterprise operations can raise prices 5% per year because switching costs make it cheaper to just pay. During inflationary environments like 2022-2023, companies with pricing power maintained margins while everyone else got squeezed.

Valuation that makes sense even in a bad scenario. Do the math on normalized earnings, not crisis earnings. If a company that normally earns $10 per share is temporarily earning $6 per share and the stock has dropped from $250 to $120, you are paying 12x normal earnings for a business that typically trades at 25x. That is a genuine opportunity. If you have to squint, invent a new valuation methodology, and assume everything goes perfectly to justify the purchase – it is not cheap enough.

The quick version for your spreadsheet:

• Debt-to-equity below 1.0
• Cash covers 2+ years of operations
• Revenue would decline less than 25% in worst-case scenario
• Products or services customers cannot stop buying
• History of maintaining or raising prices in downturns
• Trading at least 30-40% below estimated intrinsic value
• Management that has navigated previous crises intelligently

Print this out. Tape it to your monitor. When the market drops 25% and your hands are shaking, you will be glad you did.

How Should You Deploy Cash – All at Once or in Tranches?

This is the question that paralyzes people into doing nothing. They wait for the perfect bottom, the bottom never announces itself, and they end up buying nothing at all. Congratulations, you just perfectly preserved your cash while the opportunity of a decade passed you by.

Here is the reality nobody likes hearing: you will not catch the bottom. Nobody catches the bottom. The absolute low of the COVID crash was an intraday print on March 23, 2020 that lasted approximately one terrified afternoon. If your plan requires buying at the literal bottom, your plan is useless.

The solution is tranches. Deploy capital in stages as the market drops, not all at once.

A practical framework:

• First tranche (25% of crash-buying capital): Deploy when the market drops 20% from its peak. This is officially bear market territory. Quality stocks are starting to get interesting.
• Second tranche (25%): Deploy at -30%. Now you are in serious correction territory. The headlines are apocalyptic. Good.
• Third tranche (25%): Deploy at -40%. This is rare – happened in 2008-2009, briefly in March 2020. If you are buying quality businesses at these levels, the returns over the next 5-10 years will be extraordinary.
• Final tranche (25%): Keep in reserve for an even deeper drop or for specific opportunities where individual stocks have been irrationally punished.

Will you catch the exact bottom? No. Will your average purchase price be dramatically better than someone who panicked and sold? Absolutely. The math works even if you are early. If a great company drops from $100 to $40 and you start buying at $70, your average entry might be $55. That is still a fantastic price for a business you plan to hold for a decade.

The key psychological trick: treat each tranche as a separate decision. Do not think about whether the market will drop further after your purchase. It probably will. That is fine. Your job is not to time the bottom. Your job is to buy good businesses at good prices. Full stop.

How Do You Prepare Before the Crash Hits?

The worst time to build a shopping list is when the store is on fire. Every smart move you make during a crash is actually a decision you made months or years earlier.

Build a watchlist now. Know the 15-20 companies you would love to own at the right price. Know their balance sheets, their competitive positions, their normalized earnings. Calculate the prices at which they become obvious bargains. When the crash comes, you just check prices against your list. No analysis under pressure, no panic Googling, no reading Reddit threads at 2 AM trying to figure out if Meta is actually going bankrupt.

Keep cash available. When markets are going up 20% per year, holding 10-15% in cash feels idiotic. Your friends are all-in on leveraged tech ETFs. You are sitting on Treasury bills. But that cash is not dead weight – it is a loaded weapon waiting for the right target. Between 2000 and 2025, there were at least six major buying opportunities, roughly one every four years. If you are always fully invested, you cannot take advantage of any of them.

Automate the emotional part. Write down your rules. At -20%, I buy X amount of these stocks. At -30%, I buy Y amount. Tell a friend who will hold you accountable. When the moment comes and CNBC is running “MARKETS IN TURMOIL” and your portfolio is deep red, you execute the plan. Not because it feels good – it will feel terrible – but because you decided in advance, when you were calm, that this is what you would do.

Get comfortable being early. You will buy and the market will keep dropping. This does not mean you were wrong. It means you do not have a time machine. If you bought Microsoft at $180 during the 2022 selloff and it dropped further before recovering to $400+, were you wrong? Obviously not. But watching it drop after you bought felt like a punch in the stomach. Accept this in advance. It is the price of admission.

Key Takeaways

• Crashes create mispricing because selling becomes mechanical, not rational. Margin calls, ETF redemptions, and algorithmic trading push prices below business value. This is the source of the opportunity.

• Not every cheap stock is a bargain. Use a checklist: fortress balance sheet, essential demand, pricing power, and a valuation that works even in a bad scenario. Build this checklist before the crash, not during.

• Deploy capital in tranches, not all at once. Divide your crash-buying budget into 3-4 portions and deploy as the market drops through key levels. You will not catch the bottom, and that is perfectly fine.

• Preparation happens in calm markets, not panicked ones. Build your watchlist, keep cash reserves, calculate target prices, and write down your plan while your prefrontal cortex is still functioning.

• Being early is not the same as being wrong. If you buy a quality business at a 35% discount and it drops another 15% before recovering, your return is still excellent. Perfection is not the goal. Participation is.

• Cash reserves are an option on future opportunity. Holding 10-15% in cash during bull markets feels painful, but it gives you the ability to act when everyone else is liquidating at the worst possible time.

The next crash is coming. Not because I am a pessimist, but because crashes are a structural feature of markets that have occurred every few years for the past century. You do not know when it will arrive or how deep it will go. The only question is whether you will be ready – with cash, a plan, and the discipline to execute when every fiber of your being is screaming at you to sell.
