There is something fascinating about markets that I have observed repeatedly over the years.

Investors rarely become most excited about an investment before it has done extraordinarily well. They become excited after. That may sound obvious, but it explains an enormous amount of investor behavior.

South Korea offers us a wonderful recent example.

For a period, the Korean market became one of the exciting stories in global investing. Artificial intelligence, semiconductors, memory chips and companies such as Samsung and SK Hynix captured enormous attention. Taiwan had its own version of the same excitement, powered by AI and one of the world’s most important semiconductor ecosystems.

Then, suddenly, the mood changed.

A few weeks back, South Korea’s KOSPI fell so sharply that trading had to be halted for twenty minutes. At one point, the index was down more than 9 per cent before recovering somewhat to close 7.57 per cent lower. SK Hynix fell more than 11 per cent and Samsung Electronics nearly 10 per cent.

There is nothing particularly unusual about markets falling. What is interesting is how quickly our feelings towards an investment can change. When something has been rising for months or years, investors begin asking: “How do I get more exposure?”

After it falls sharply, they begin asking: “Should I get out?”

The investment changed in price. However, the investor changed in psychology.

This is where the more important lesson lies. There is a strange cycle that plays out repeatedly in investing.

An asset begins performing well. Initially, very few people notice. Then performance attracts attention. Attention creates stories. Stories attract money. Rising prices validate the stories. More people enter. Eventually, what began as an investment becomes a consensus. Then consensus feels incredibly comfortable.

Everybody appears to agree. The television experts agree. Fund managers talk about it. Articles explain why this market has entered a new era. Your friend already owns it. Someone at dinner tells you how much money he has made.

Then something happens. The fact that an investment has gone up becomes one of the reasons we believe it will continue going up.

We call this analysis. Many a times, it is simply recency wearing a suit.

The human mind has an extraordinary tendency to take what has happened recently and project it into the future. If an asset has performed badly for several years, we struggle to imagine why anyone would own it. If it has performed brilliantly, suddenly the reasons for owning it appear obvious.

The fundamentals may genuinely have improved. The investment thesis may be perfectly sound. However, price changes psychology. This is why the same investment can feel risky at Rs.100, attractive at Rs.150 and irresistible at Rs.250.

Nothing about that sequence makes logical sense. Emotionally though, it makes perfect sense. Rising prices make us feel safer precisely when the investment may be becoming more expensive. Falling prices make us feel more frightened precisely when future expected returns may be improving.

Markets have a remarkable ability to make comfort expensive and discomfort cheap. This does not mean Korea is now cheap. It does not mean Taiwan is expensive. It certainly does not mean anybody should buy or sell either market based on a few days of movement.

This is not the point. The real point is much bigger.

Whenever something becomes extraordinarily popular, investors should become aware of what popularity is doing to their own thinking.

Are we investing because this asset belongs in our financial plan or because we are tired of watching somebody else make money from it? Unfortunately, the second one often disguises itself as the first.

We tell ourselves we are increasing international diversification. But why did diversification suddenly become urgent after that international market rose dramatically?

We tell ourselves we are increasing exposure to technology. But why did technology become essential only after technology stocks had already created enormous wealth?

We tell ourselves we believe in gold, small caps, AI, emerging markets, private markets, real estate or whatever happens to be performing exceptionally well at the time. We genuinely might believe so.

Every investor should occasionally ask a deeply uncomfortable question: Would I be equally excited about this investment if I had not seen its recent return? This one question can reveal a lot. Performance does something extraordinary to our perception of risk. When an investment has been rising steadily, risk begins to feel theoretical. 

We know intellectually that markets can fall. We know corrections happen. We have seen charts showing previous crashes. We may even tell our financial professional that we are long-term investors and would happily buy more if markets corrected.

Then the correction arrives. Suddenly, risk is no longer a paragraph in a presentation.

It is Rs. 50 Lakh disappearing from the screen. It is three years of gains disappearing in three weeks. It is a headline saying trading has been halted. It is the investment everyone wanted yesterday becoming the investment nobody wants today.

This behavior reveals one of the strangest truths about investing. We often discover our real risk tolerance only after the risk arrives.

Before that, we are answering hypothetical questions.

“How would you feel if your portfolio fell 20 per cent?”

I wilk be fine.

“What about 30 per cent?”

I am a long-term investor.

“What would you do?”

Buy more.

That’s great.

Then the market falls 30 per cent and the conversation changes completely. This happens because as we know imagined discomfort and experienced discomfort are two very different things. This is why diversification matters so much. It’s not because diversification guarantees that nothing in your portfolio will ever fall.

As I have written repeatedly, it’s quite the opposite. A genuinely diversified portfolio almost guarantees that something you own will periodically disappoint you. At any given moment, one market will look brilliant and another boring. One asset class will be making headlines while another appears useless. One fund will outperform while another struggles. One country will become fashionable while another is ignored.

This is not evidence that diversification has failed. It may be evidence that diversification exists. If everything in your portfolio is doing brilliantly at the same time, you may want to ask whether you are really diversified or simply holding different versions of the same trade.

This is where investors get into trouble during powerful trends. The outperforming asset gradually becomes more attractive. This happens not only because its price is rising, but because everything else begins to feel like dead weight.

Why own this boring fund? Why hold debt? Why own another geography? Why maintain gold?

Why not increase exposure to what is clearly working?

Slowly, diversification begins to feel like an obstacle to returns until the cycle turns. Then the boring assets suddenly rediscover their purpose. This is why I have always believed that diversification feels most unnecessary just before you are reminded why you needed it. Its value is rarely obvious during the party. You understand it when the music stops.

There is another important lesson here. A great investment and a great investment at any price are not the same thing. A wonderful country can be a terrible investment at the wrong valuation. A wonderful company could deliver disappointing returns if investors paid too much for the wonderful story. An extraordinary technology can transform civilization while some of the investments built around that technology still produce poor outcomes.

These ideas can coexist. The internet changed the world. This did not mean every internet stock was a wonderful investment. Railways transformed economies. This did not mean every railway company made investors rich. Artificial intelligence may turn out to be one of the most consequential technologies humanity has ever developed. This still does not mean every AI-related investment purchased at every valuation will produce extraordinary returns.

A great story does not eliminate the importance of the price you pay for participating in it.

This is why investing is so difficult.

We are not merely analyzing businesses, countries, technologies and markets. We are analyzing them while being emotionally influenced by their recent prices. The investment that has risen 100 per cent arrives with a beautiful story and social proof. The investment that has fallen 40 per cent arrives carrying embarrassment, doubt and frightening headlines.

Future returns do not care about which investment makes us feel more comfortable today. Markets do not reward us for emotional convenience. They reward us, imperfectly and unpredictably, for the risks we take and the prices we pay. This is why a thoughtful investment process must be designed before excitement arrives.

How much international exposure should we have? How much equity? How much debt? How much gold? How much concentration are we comfortable with?

What role does each investment play?

When will we rebalance? What would make us change our allocation?

These decisions should ideally emerge from our financial life, not from whichever asset happened to make the most money last year.

If we don’t follow this, the portfolio will always be chasing yesterday and yesterday is an extraordinarily expensive investment advisor.

Think about how wealth is built. It’s not built by owning everything that becomes fashionable. It’s also not built by perfectly predicting every winning market. It’s most certainly not by moving from India to Korea to Taiwan to America to gold to small caps to whatever comes next.

Wealth is built by having a thoughtful plan, owning productive assets, diversifying intelligently, rebalancing periodically and allowing enough time for compounding to do what excitement never can.

I know this sounds boring. It is. This is precisely why so few people do it consistently. There will always be something doing better than what you own. If you own Indian equities, some international market will eventually outperform. If you own global equities, some concentrated technology portfolio will outperform. If you own diversified funds, somebody’s three-stock portfolio will occasionally make yours look foolish.

If you own equities, gold will sometimes soar.

If you own gold, equities will eventually make it look useless.

There is no portfolio that protects you from the emotional pain of watching something you don’t own perform brilliantly.

The only way to own every winner is to know the future and unfortunately, that remains unavailable to all of us. Maturity in investing therefore begins when we stop asking, “What should I own because it is doing well?” and start asking, “What should I own because it belongs in my financial life?”

If you manage to do this, now the portfolio is no longer being constructed around markets. It is being constructed around you… Your goals… Your time horizon… Your liquidity needs… Your ability to tolerate uncertainty… Your need for growth… Your need for protection of your purchasing power… and your ability to sleep when the investment everybody loved last month suddenly falls 20 per cent.

This brings us back to South Korea.

A market falling sharply in a few days does not tell us what it will do next. It may fall further. It may recover quickly. The companies involved may continue producing extraordinary earnings, or expectations may need to adjust considerably.

I don’t know and neither does anybody else. This is precisely the point.

You do not need to know what Korea does next to learn something valuable from what just happened. You need to notice what happens inside investors when markets move dramatically.

When prices rise, uncertainty disappears from our imagination. When prices fall, opportunity disappears from our imagination. At the top, we extrapolate the good news. At the bottom, we extrapolate the bad.

The market changes price. Our mind changes the story. A thoughtful investor tries to separate the two.

The next fashionable market will come. The next fashionable asset class will come. The next transformative technology will come. There will be charts showing extraordinary recent returns. There will be compelling narratives explaining why the old rules no longer apply. There will be friends who got in earlier and made far more money.

Somewhere inside you, a small voice might whisper: “I am missing out.”

When that happens, don’t automatically ignore the opportunity. 

Study it…Understand it…You might even invest in it if it genuinely deserves a place in your portfolio.

Ask yourself one question before you do: Am I buying this because of what I believe about its future, or because I cannot emotionally tolerate what it did without me in the past?

This is one of the greatest paradoxes in investing. 

When nobody wants an investment, we demand reasons to buy it. When everybody wants it, we stop demanding reasons. We borrow confidence from rising prices and courage from the crowd. Then prices fall, the crowd disappears and suddenly we want certainty before staying invested. Markets however have never offered certainty. They offer something far less comfortable.

Possibility and this thing called possibility comes with uncertainty. The lesson from South Korea is not “Don’t invest in South Korea.” It is not “AI is a bubble.” It is certainly not “Sell technology.”

The real lesson is far more enduring: Never allow recent returns to do your thinking for you.

Own investments because they have a role in your financial life. Diversify because you cannot know which market will lead next. Rebalance because yesterday’s winner should not quietly become tomorrow’s entire portfolio. Finally remember that the moment everybody agrees something is obvious is often the moment when you should become more thoughtful, not less.

Every market cycle eventually teaches investors the same lesson.

The investment everybody wants can become the investment everybody fears with astonishing speed. Then, eventually, something nobody wants today will become the investment everybody wishes they had bought.

Markets change their favorites. Your financial life and roadmap should not have to.
