Mutual Funds And Behavioural Biases: Why Investors Exit Too Early And Miss Compounding
Nobody plans to bail early. That’s what makes this so frustrating. Every single investor who starts a SIP or drops a lump sum into mutual funds says the same thing. I’m in this for the long haul. I won’t flinch. I’ll let compounding work.
Then the market tanks 12% in a month. A colleague casually mentions he moved everything into fixed deposits. Some news anchors say the word “crash” three times in one segment. And just like that, the long-term conviction evaporates. You redeem. Not because anything changed in your financial life. Because something flipped in your head.
That flip has a name. Actually, it has several.
Loss Aversion: Losses Sting in a Way Gains Never Match
This one runs deep. Behavioural economists have poked at it for decades, and the finding refuses to budge. Losing money feels roughly twice as painful as making the same amount feels good. A 10% drop and a 10% gain are not emotional equals. Not even close. The drop sits in your chest. The gain barely registers by Tuesday.
For anyone holding mutual funds, this creates a very specific trap. During a correction, watching your portfolio shrink becomes physically uncomfortable. Redeeming feels like relief. Your brain actually rewards you for hitting that button because the pain stops immediately.
What doesn’t it show you? The bill for that relief. Those units you sold at a loss are gone. They can’t participate in the recovery. And recoveries- this part is worth sitting with tend to arrive faster than anyone expects while they’re in the middle of the downturn. By the time things feel “safe” again, the bounce has already happened. You watched it from the sidelines because your amygdala made a financial decision your prefrontal cortex never approved.
Recency Bias: Last Quarter Is Not a Crystal Ball
This one’s sneakier. Recency bias means you give way too much weight to whatever happened most recently. Mutual funds had a great quarter? Money floods in. Rough quarter? Redemptions spike. Same error, different direction. You’re taking a tiny window and stretching it across the future like it’s a forecast.
It’s not a forecast. Markets don’t extend in straight lines. A terrible quarter can sit right next to a brilliant one. A spectacular run can precede months of nothing. But the recent past feels like the most important data because it’s the freshest thing in your memory. Your brain treats “recent” and “relevant” as the same word. They’re not.
And here’s the compounding problem. Investors who check their portfolio every day encounter more recency triggers than those who check once a quarter. More triggers, more emotional reactions. More reactions, more premature exits. The person checking daily isn’t more informed. They’re more exposed. Big difference.
The Usual Suspects: How Each Bias Shoves You Toward the Door
| Bias | What It Looks Like | What It Actually Costs |
| Loss Aversion | Redeeming during dips to “stop the bleeding” | Misses the recovery that usually follows |
| Recency Bias | Assuming last month’s slump is the new normal | Exits right before mean reversion kicks in |
| Herd Mentality | Selling because your WhatsApp group is selling | Locks in losses at the worst collective moment |
| Anchoring | Obsessing over a past portfolio peak as the “real” value | Refuses to stay unless that exact number returns |
Not exhaustive. But those four explain the vast majority of early exits from mutual funds. If you’ve ever redeemed and regretted it a few months later, one of those was probably calling the shots.
Compounding Doesn’t Care About Your Intentions
People talk about compounding like it’s automatic. Invest, and it kicks in. That’s half the story. The other half, the part nobody likes hearing, is that compounding only works while you’re still there.
Every year you remain invested, the base grows. Pull out and you don’t just miss next year’s gain. You miss the compounding on that gain for every year after. The cost isn’t a straight line. It curves. Sharply. And you can’t see it at the time because it only shows up in the hypothetical portfolio you didn’t stick around to own.
The investors who actually build wealth through mutual funds aren’t stock-picking geniuses. They’re the ones who stayed put. Through corrections, through scary headlines, through that one uncle at Diwali who swore he timed the exact bottom. Staying is the strategy. Everything else is noise.
Conclusion
Your biggest risk in mutual funds isn’t the market. It’s you. Loss aversion, recency bias, herd behaviour, anchoring. Every single one points at the same exit door, and every single one sounds completely reasonable in the moment. The only real defence is knowing these patterns exist, catching yourself when
they’re steering, and having committed to a plan before the panic showed up. Compounding rewards patience. But only patience you actually follow through on. Not the kind you thought you’d have.
