Rajesh, a senior finance professional, had over 25 years of experience. Numbers were his strength, and colleagues trusted his judgment.
One evening, he proudly shared how one of his investments had doubled in value.
When I asked, "How has your overall portfolio performed over the last five years?"
He smiled... and changed the subject.
It made me realise something important.
Intelligence doesn't always make us better investors. Sometimes, it works against us.
Here's why:
👉 Ego: We refuse to admit a mistake and continue holding losing investments.
👉 Confirmation Bias: We only read news that supports our opinion and ignore warning signs.
👉 Overconfidence: A few successful investments make us believe we're experts.
👉 Herd Mentality: We buy because everyone else is buying—and often enter when prices are already high.
Markets don't reward intelligence alone.
They reward discipline, patience, humility, and emotional control.
Remember: In today's world of social media tips, AI-generated advice, and WhatsApp "hot stock" messages, your biggest investment risk is not market volatility—it's your own behaviour.
