Behavior-Based Financial Planning: How to Manage Your Investing Behaviour
Finnovate’s editorial team researches and creates financial content using trusted sources, regulatory references and inputs from subject experts.
Imagine two investors with the same income, the same goals, the same ₹50 lakh portfolio and the same retirement timeline.
Then markets fall sharply.
One continues with the financial plan.
The other stops SIPs, sells a large part of the equity portfolio and decides to return only when markets “look safe again”.
Their financial plans were identical.
Their behaviour was not.
Behavior-based financial planning considers not only your goals, investments and ability to take risk, but also how you may behave when the plan becomes emotionally difficult to follow.
The goal is not to remove emotion from investing. It is to create a process so that every emotion does not automatically become an investment decision.
Financial Planning, Risk Profiling and Behaviour Are Not the Same Thing
Traditional financial planning usually begins with your goals, time horizon, savings requirement, cash flow and investment structure.
Risk profiling adds another question:
Behavior-based planning adds a third question:
Someone may say in a questionnaire that a 20% market decline is acceptable.
Watching their own ₹50 lakh portfolio fall can feel very different.
Your Portfolio Has Market Risk. Your Plan Has Behaviour Risk.
Market prices can recover or fall further. Nobody knows the path in advance.
But selling, stopping investments or changing your allocation is a decision you control, and that decision can materially change the financial plan.
What Indian Investor Behaviour Tells Us
The SEBI Investor Survey 2025 gives us a useful picture of the tension inside Indian investment decisions.
Source: SEBI Investor Survey 2025. The survey also found that 56% of investors used financial influencers as an information source.
Among dormant investors, SEBI grouped poor-performance-related reasons such as lower returns, volatility and significant losses as a major reason category for 87%.
This gives us two important behavioural tensions.
And investment decisions do not happen only inside spreadsheets.
They happen while markets move, friends discuss returns, social feeds show successful trades and someone always seems to know which investment will rise next.
Five Behaviours That Can Disrupt a Good Investment Plan
These behaviours do not affect every investor in the same way.
The important point is that knowing their names does not necessarily prevent them from influencing decisions.
The ₹50 Lakh Investor During a Market Fall
Assume the planned portfolio is:
Now assume the equity portion falls 20%.
The investor now sees:
This is where behaviour starts to matter.
The Market Fall Also Changed the Asset Allocation
There is another change inside the same example.
The market movement has already altered the portfolio.
That creates a much better question:
That is very different from:
Behaviour Risk Works Both Ways
Investor behaviour does not become a problem only when markets fall.
Same investor.
Same goals.
Different market environment.
Different perception of risk.
Why Knowing Your Bias Is Not Enough
Learning about behavioural finance helps.
But an investor usually does not need a psychology lesson while the portfolio is falling.
They need a process that was decided before the fall happened.
SEBI's Investor Survey 2025 found that only 36% of current investors had moderate or high securities-market knowledge under the survey's methodology.
A 2026 study of 519 active Indian retail investors also found that higher financial literacy in its sample was associated with lower herding and availability effects, but it did not find a statistically significant relationship with overconfidence.
The study used a specific digitally active sample and does not establish cause and effect for all Indian investors.
This is why systems can matter alongside education.
Five Behaviour Guardrails for Investors
The aim is not to predict every emotional reaction.
It is to build a process around the decisions that matter most.
A Simple Decision Journal
Before making a significant portfolio change, answer:
- What am I changing?
- Why am I changing it?
- What changed in my financial plan?
- Would I make the same decision if markets had not moved recently?
- What would make me reconsider this decision?
This creates a small gap between feeling something and doing something.
That gap can be useful.
Your Risk Profile Can Feel Different in Different Markets
During a strong bull market:
After a sharp fall:
After markets recover:
The financial goal may have remained unchanged throughout.
What changed was the experience of risk.
That is why actual past behaviour can add useful context to a traditional risk questionnaire.
Questions such as these can be informative:
- What did you do during the last major market decline?
- Have you stopped SIPs during previous corrections?
- Do you increase risk after strong returns?
- How often do you change investments?
- What usually makes you reconsider the portfolio?
Past behaviour does not perfectly predict future behaviour.
But it can reveal something that a hypothetical questionnaire may miss.
What Should Actually Trigger a Portfolio Review?
Where Does Financial Planning Fit?
A financial plan cannot predict every market fall.
And no financial planner can remove emotion from investing.
What a good planning process can do is create distance between:
That can happen through documented goals, predefined asset allocation, periodic reviews, decision rules and a second check before making large portfolio changes.
The value is not having an emotionless investor or adviser.
It is having a process that makes important financial decisions harder to make impulsively.
Final Takeaway
Markets will sometimes fall after you invest.
An asset you did not buy will sometimes outperform the one you own.
Someone you know will occasionally make money from something you ignored.
Headlines will repeatedly suggest that something has changed forever.
None of this can be removed from investing.
What can be improved is the process between:
It should also help decide what you will do when markets test the plan.
FAQs
1. What is behavior-based financial planning?
Behavior-based financial planning considers an investor's goals, finances and investment risk alongside how the investor may respond to market movements, losses, recent performance and outside influences. It uses predefined processes and decision rules to reduce impulsive portfolio changes.
2. What is behavioural finance in investing?
Behavioural finance studies how psychology and emotions can influence financial decisions. Examples include loss aversion, herd behaviour, overconfidence, anchoring and placing too much importance on recent events.
3. What is behaviour risk in investing?
Behaviour risk is the risk that an investor's own decisions materially affect the financial plan. Examples can include selling after a market fall, repeatedly chasing recent winners or increasing risk mainly because markets have recently performed well.
4. What are common behavioural biases among investors?
Common examples include loss aversion, recency bias, herd behaviour, overconfidence and anchoring. Different investors may experience these behaviours differently and at different times.
5. How can investors reduce emotional investment decisions?
Useful steps can include setting asset allocation in advance, defining valid reasons for reviewing the portfolio, following a review process, deciding how to respond to market falls before they happen and documenting the reason behind major portfolio changes.
6. How is behavior-based financial planning different from risk profiling?
Risk profiling generally looks at an investor's ability and willingness to take investment risk. Behavior-based financial planning also looks at how the investor may actually respond when that risk becomes real, such as during a large market fall or strong market rally.
