The Pitfalls of Market Timing – And Why FOMO is Your Worst Financial Adviser 12Jul2025
In many cases, it seems almost inevitable—a stock often explodes right after we sell it.
Let me recount a personal experience. I held Bharti Airtel stock for nearly a decade. The stock underperformed for much of that time, and like many long-term investors, I grew frustrated. In 2019, I finally gave up and sold my shares at Rs 340 a piece, thinking I had cut my losses and moved on.
But then, something unexpected happened: Airtel stock surged. Over the next six years, the stock multiplied almost six times—a painful reminder of what I had missed.
But Airtel wasn’t the only one. Several other stocks in my portfolio have taught me similar lessons—about patience, timing and the emotional cost of investing.
Behavioral Finance in Action
Looking back, many of my mistakes weren’t analytical—they were emotional:
I acted out of exasperation and fatigue, not fundamentals.
Loss aversion: I was more focused on the years of underperformance than the long-term potential.
I fell into recency bias, letting short-term pain cloud long-term thinking. Market timing feels rational in the moment, but it's often driven by emotion and short-term thinking. In my case, it meant exiting just before the real returns began.
Anchoring bias: Once I sold, regret and anchoring kept me from re-entering. I was anchored to my sell price of Rs 340. Every new price felt "too high," even though the fundamentals had changed. Having made a decision, I subconsciously wanted to "stick with it" to avoid admitting I was wrong.
Daniel Kahneman’s work, especially in Thinking, Fast and Slow, now resonates deeply:
While I’ve made clear errors, such as selling Bharti Airtel prematurely, the overall resilience of my equity portfolio shows the power of staying invested. Over the long term, the portfolio has outperformed the market by almost 10 percentage points—a reminder that patience and discipline often beat perfect timing.
Key takeaways:
> Better to avoid emotional selling and buying
> Making fewer, deliberate decisions outfoxes frequent, reactive ones
> Stay invested in quality and let compounding do the magic for you
> Mistakes are part of the journey, but staying invested for long time pays off
> I can forecast when the market will go up or down (despite overwhelming evidence that even professionals can't consistently predict short-term market moves)
> I'll be able to get in and out before the crowd (in a stampede, everyone gets trampled including the ones who thought they were ahead)
> I’ll know when to sell and when to get back in (as the story of Abhimanyu fighting in the Padmavyuham reminds us—-getting in may be easy, but getting out safely is another matter altogether)
> Timing the market will outperform buy-and-hold investing (long-term data show most market timers underperform simple buy-and-hold strategies)
I know I’m susceptible to biases—overconfidence, loss aversion and the temptation to time the market—but I’ve learnt to recognise their patterns in my investment decisions. While I can’t eliminate them entirely, I strive to manage them, and that awareness has made me a more grounded investor over the years.
But here’s the kicker: just when most people gave up or sat on the sidelines, the market quietly began a one-way recovery from Mar2023 onwards.
Just check the Nifty price chart from Jan2021 to Dec2023, with high volatility between 18Oct2021 and 20Mar2023:

Apr2022: Market bounces back in just 28 calendar days--with Nifty 50 rising by 13.8 per cent to 18,053. Regret sets in. “Why did I sell?”
May2022: Fear & panic: Market falls again by 12.6 per cent to 15,782 in just 39 days. "Thank god, I sold early."
Aug2022: Big rally of 17.4 per cent, in 62 days, with Nifty 50 touching 17,957 on 18Aug2022. “Should I get back in now?”
Dec2022: Hope & re-entry: Market hits 18,888. FOMO peaks. “I can’t miss this run!”
Mar2023: Frustration & whipsaw: Boom, back to 16,828! Down 10.9 per cent. “What just happened?!”
This constant back-and-forth is what Kahneman described so well. We’re not reacting to fundamentals. We’re reacting to emotion—to fear, to greed, and to what just happened yesterday.
> Pulled out money “to re-enter later”
Then, during the smooth and steady rally (Mar2023 to Sep2024), they:
FOMO (Fear of Missing Out) makes you act like a momentum chaser. You buy when everyone’s buying, and sell when everyone’s panicking. In a market ruled by cycles, you could end up always one step behind with FOMO.
This is exactly how FOMO plays out in investing. You watch people posting about their portfolio gains—-and it feels like you have to get in. The fear of missing out makes you act impulsively, but in the process, you might end up getting caught in the chaos of market volatility.
Here’s the boring-but-effective truth:
> Volatility is normal, not a red flag
> The market rewards patience, not panic
And yet, Indian equities showed surprising resilience. That probably added another layer of confusion for investors trying to time the market. You’d sell thinking things are about to get worse, only to watch Indian stocks stay steady while the rest of the world fell apart.
This “wait and watch” mindset often turns into “wait and miss.” And as Kahneman reminds us, our brains love to find patterns—even when none exist. We overreact to recent moves, anchor to past highs and assume what happened in the US or Europe will automatically happen here.
From the lows of Mar2023 till the all-time-highs of Sep2024, Nifty 50 index surged by a staggering 56 per cent, moving from 16,800 to 26,200 within just 18 months.
But here’s the irony. That bout of volatility—the kind that tempts you to sell, trade more often or sit on the sidelines with oodles of cash—was exactly what set the stage for the next bull phase.
The following 18 months, from Mar2023 to Sept2024, turned out to be hugely rewarding for those who stayed invested.
7. Final Thoughts
But here's the thing: for most people, trying to time the market through that choppy, uncertain phase likely meant missing out on what came next.
You don’t need to be perfect. You just need to stay invested. In investing, doing nothing often beats doing something emotional.
