When Readers Ask: “So What Should I Actually Do?”

From time to time, I receive messages / questions like this:

“Though it's interesting to know the shortcomings ( biases / behavioral finance) we may be facing, it doesn't really help noobs, or maybe even more seasoned investors, on what to do to avoid them. Does anyone have anything to share to expand on the things to do to become more disciplined, define exit strategy, things like that?”

It’s a fair question. In fact, it’s probably one of the most honest questions an investor can ask.
Because understanding behavioural finance is one thing. Applying it in real life, when markets are moving, headlines are loud, and your portfolio is flashing red or green , that’s a completely different game.

And here’s the uncomfortable truth. There isn’t a clean, step-by-step formula you can follow and suddenly become “disciplined”. If there were, everyone would be doing it already. Behavioural finance doesn’t sit neatly in a spreadsheet. You can’t model it like earnings growth or discount cash flows. It’s messy, personal, and changes over time. That’s why I’ve always felt that behavioural finance is more of an art than a science.

But just because it’s not precise doesn’t mean it’s useless. It just means we need to approach it differently.



Why You Can’t Treat Behavioural Finance Like a Trading Rule

One common mistake I see is trying to turn behavioural finance into something mechanical. Investors ask, “So what’s the rule? When do I enter? When do I exit?” as if it works like a trading system with clear price triggers.

But behavioural finance doesn’t work that way.
You can define a buy price for a stock. You can set a stop-loss level. These are objective, measurable, and easy to execute. Behaviour, on the other hand, is not. You can’t say, “If fear hits 7 out of 10, I will buy,” or “If greed reaches a certain level, I will sell.” It simply doesn’t translate cleanly into numbers.

More importantly, behaviour shows up differently each time. A 20% market drop today may feel very different from a 20% drop five years ago, depending on the macro environment, your portfolio size, or even your personal situation. There is no fixed “trigger point” that guarantees the same reaction.

This is why trying to force behavioural finance into a rigid entry/exit framework often backfires. It gives a false sense of control. You think you’ve solved the problem by creating rules, but when the moment comes, emotions still find a way to override them.

Instead of treating behavioural finance like a trading system, it’s more useful to see it as a layer that sits on top of your strategy. It shapes how you execute, not what exact price you act on.

In other words, behavioural finance doesn’t tell you when to buy or sell. It helps you understand why you are making that decision — and whether that reason is grounded or emotional.

Why There’s No Simple Playbook

Most investors are used to thinking in frameworks. Buy when valuation is cheap. Sell when it’s expensive. Cut loss at a certain percentage. Rebalance annually. These are useful guidelines. But behaviour doesn’t always follow guidelines.

Two investors can hold the same portfolio, with the same rules, and still end up with very different results. Why? Because when markets move, one sticks to the plan, and the other hesitates, delays, or overrides it.

The issue isn’t the strategy. It’s the execution.
And execution is driven by behaviour.
This is why when people ask for a “system” to fix behavioural mistakes, the answer often feels unsatisfying. You can create rules, but you can’t fully automate discipline. At some point, you still have to make a decision in real time, with incomplete information and emotional pressure.
So instead of searching for a perfect system, it might be more useful to think in terms of habits and processes.



Small Actions, Repeated Quietly

If there’s one thing I’ve learned over the years, it’s this: behaviour shows up in small, almost invisible actions. Not the big dramatic moments. Not the once-in-a-decade crisis decisions. But the regular, day-to-day choices.

Do you check your portfolio ten times a day, or once a week?
Do you chase a stock after it’s already run up, or do you wait?
Do you read opposing views, or only things that confirm your belief?
Do you add during weakness, or do you freeze?

None of these actions feel significant on their own. But over time, they compound.
In a way, behavioural discipline works just like financial compounding. Small, consistent actions build into meaningful outcomes. Poor habits, repeated often enough, also compound ,  just in the wrong direction.

The challenge is that results don’t show immediately. You can make poor decisions and still get away with it in a rising market. You can make sensible decisions and still look wrong in the short term.

That delay between action and outcome is what makes behavioural finance so hard to apply.



Building Discipline Without Overcomplicating It

So how do you actually become more disciplined? Not by trying to change everything at once. That rarely works. It’s usually more effective to put in place simple structures that guide your behaviour, especially when emotions are high.

One approach is to reduce the number of decisions you need to make under pressure.
For example, instead of deciding whether to buy during a market dip in the moment, you can pre-commit to a plan. If the market falls by a certain range or % point, you deploy a portion of cash. Not because you feel confident at that time, but because you already decided when you were calm.

This doesn’t eliminate emotion, but it reduces its influence.

Another way is to slow yourself down. Many behavioural mistakes happen because decisions are made too quickly. A stock drops sharply, and the instinct is to sell immediately. A stock rallies, and the urge is to chase.

Adding a simple pause , even 24 hours  can change the outcome. It gives you time to think, to revisit your original thesis, and to separate noise from signal.

Discipline isn’t about never feeling emotional. It’s about not letting those emotions dictate immediate action.



The Reality of Exit Strategies

Exit strategies are something investors like to talk about, but in practice, they are harder than they sound. On paper, it’s easy. Sell when fundamentals deteriorate. Sell when valuation becomes stretched. Cut loss when thesis is broken. In reality, none of these are clear-cut.

Fundamentals don’t deteriorate overnight in a neat, obvious way. Valuations can stay “expensive” for years. Prices can fall without the thesis being wrong, and they can rise even when the thesis is weak.

This is where behaviour creeps in again.
Some investors sell too early because they fear losing gains. Others hold on too long because they don’t want to admit they were wrong.
Instead of trying to define a perfect exit rule, it may be more useful to define conditions that trigger a review.

For example, if a company’s earnings decline consistently over a few quarters, or if management changes its strategy in a way that no longer fits your original thesis, that’s a signal to reassess.

The decision to exit doesn’t have to be immediate. But it should be intentional.
What matters is not having a rigid rule, but having a clear understanding of why you entered the position in the first place. Without that, it’s very hard to know when to leave.



Writing Things Down Changes Everything

One of the simplest but most effective tools I’ve found is writing. Before entering a position, write down your reasons. What do you expect to happen? What could go wrong? What would make you change your mind?

It doesn’t have to be long or formal. Just clear enough that you can revisit it later.
This does two things.

First, it forces clarity. Vague ideas become more concrete when you try to put them into words.
Second, it creates accountability. When markets move, it’s easy to rewrite your own narrative. A written record keeps you honest.

Over time, you can look back and see patterns in your decisions. Where you were too optimistic. Where you were too cautious. Where you reacted emotionally.

This feedback loop is how behavioural awareness slowly turns into behavioural improvement.


Accepting That You Won’t Get It Right All the Time

One of the biggest traps in investing is the desire to be right. Behavioural mistakes often come from this need. Holding on to a losing position because selling would mean admitting a mistake. Chasing a rising stock because you don’t want to miss out again.

But investing isn’t about being right all the time. It’s about being roughly right over time.
Even good investors make plenty of mistakes. The difference is that they manage those mistakes. They don’t let a single bad decision derail the entire portfolio.

Accepting this changes behaviour. It becomes easier to cut a position that no longer makes sense. It becomes easier to stay patient when things are not moving.

Perfection is not required. Consistency is.


The Slow Feedback Loop

One reason behavioural finance feels abstract is because feedback is slow. If you touch a hot surface, you learn immediately. In investing, you can make a poor decision and still see positive results in the short term. Or make a good decision and see negative results for a while.

This makes it harder to link cause and effect.
Over time, patterns do emerge. But it requires patience and reflection. Looking at your portfolio once a year is not enough. You need to observe your own reactions during different market conditions. What did you feel during a downturn? What did you do during a rally?

These observations are data points. Not numerical, but behavioural. And just like financial data, they become more meaningful over time.


Behavioural Finance as an Ongoing Practice

It’s tempting to think of behavioural finance as something you “learn” and then move on.
In reality, it’s ongoing.

Your behaviour changes as your portfolio grows. It changes after you experience a market crash. It changes after a period of strong returns.
What felt comfortable at one stage may feel very different later.

This is why rigid rules often fail. They don’t adapt to changing circumstances.
Instead, think of behavioural finance as a practice. Something you revisit, adjust, and refine over time. Not perfect, but improving.

Bringing It Back to Everyday Investing

So how does all of this translate into day-to-day investing?

Not through a perfect checklist, but through awareness and small adjustments.

You become a bit more patient before acting. ( You don't FOMO when everyone is buying a hot or hype stocks)

You become a bit more honest about your reasons. ( Accept that we are not perfect and do make mistakes, we tend to have lemons in our portfolio.)

You become a bit more comfortable with uncertainty. ( That market move in cycles, not every year we will have double digits gains or win in every bet).

Individually, these changes are small. But over years, they shape your investment journey in a meaningful way.

And that’s really the point.


Final Thoughts

I understand why readers ask for something concrete. Investing already feels uncertain, and behavioural finance adds another layer that seems even less defined.

But maybe that’s the wrong way to look at it.
Behavioural finance isn’t meant to give you precise answers. It’s meant to improve the quality of your decisions over time.

It’s not about eliminating mistakes. It’s about reducing avoidable ones. It’s not about having perfect discipline. It’s about building enough structure to stay on track when it matters.

And most importantly, it’s about recognising that the biggest factor in your portfolio isn’t just what you buy or sell , it’s how you behave along the way.

That part doesn’t show up in numbers immediately. But give it time, and it becomes very clear.

Till next update! Cheers!😊🥂
