The One-Portfolio Mistake: Why One Investment Can’t Fit Every Goal

Noida-based Debjit Sinha started investing at 29 and felt invincible. He’d opened an equity mutual fund, set up a SIP (systematic investment plan), and watched his money grow month after month. When a colleague asked where he kept his emergency fund, he grinned: “Same mutual fund. Why scatter money across accounts when one fund is performing so well?”

Six months later, his father needed an immediate bypass surgery of Rs 4.5 lakh. He had Rs 4.2 lakh accumulated. Perfect, except for one thing: the market had corrected 18 per cent that very week. His fund value had dropped to Rs 3.4 lakh.

He was suddenly short by Rs 1 lakh.

He borrowed on credit cards at a very high interest, eventually redeeming his units at a loss. The surgery went well; his father recovered. But his finances didn’t. His portfolio took years to rebuild not because he invested badly, but because he mixed a short-term emergency safety net with a long-term growth instrument.

The Fatal Assumption

Many Indians don’t lose money because of “wrong” investments. They lose money because they use the same investment for goals with dramatically different timelines. Your emergency fund has nothing in common with your retirement corpus except that both are yours. One needs accessibility tomorrow. The other needs growth for decades. Treating them the same is like wearing a raincoat to a wedding because “it’s all clothing.”

Says Sanjiv Bajaj, Joint Chairman & MD at Bajaj Capital: “Families make this mistake every day putting wedding money in stocks, keeping retirement savings in a low-interest savings bank, mixing a three-year car fund with a twenty-year wealth goal. Convenience replaces strategy, and the cost shows up later. Most portfolio disasters aren’t caused by market crashes. They’re caused by time-horizon mismatches. You can survive a 30 per cent fall if your goal is 15 years away. You cannot if your daughter’s school fees are due next month.”

The Three-Bucket Framework: Now, Next, Later

The smartest way to invest is to separate money based on when you need it.

Bucket 1: NOW (0–3 years) - Safety & Liquidity

This is survival money: emergency funds, near-term expenses, medical contingencies, EMIs, school fees due next year.

Use:

• Liquid or ultra-short debt funds

• Fixed deposits

• High-interest savings with sweep

Avoid equity. You don’t have the time to recover from a dip.

Bucket 2: NEXT (3–7 years) - Balanced Growth

For medium-term goals like a home down payment, business expansion, or child’s education in 4–6 years.

Use:

• Hybrid/balanced funds

• Conservative hybrids for 3-4 year goals

• Aggressive hybrids for 6-7 year goals

• Short/medium duration debt funds if risk-averse

You need growth but with cushioning.

Bucket 3: LATER (7+ years) - Aggressive Growth

This is long-term money: retirement, children’s higher education, wealth creation.

Use:

• Equity mutual funds

• Index funds (Nifty 50, Next 50)

• Sectoral funds (only if you understand them)

• Direct equity (only with skill and time)

Here, volatility isn’t danger; it’s opportunity. Time is your shock absorber.

The Rebalancing Discipline

Goals move between buckets as time passes. Your child’s college fund starts in “Later,” becomes “Next” when they enter their teens, and finally “Now” two years before admission.

Example: Saving Rs 15,000/month for a goal 12 years away:

• Years 1–7: 100 per cent equity

• Years 8–10: Shift 30 per cent to hybrids

• Years 11–12: Move majority to liquid/short-term debt

This de-risks the goal without killing growth.

Bajaj says, “Realising 18 months before your goal that your money is in the wrong instrument leaves you with two bad choices: withdraw at a loss or delay your goal. Bucket planning eliminates that trap.”

Your Action Plan

List every goal. Assign to Now, Next, or Later. Check where your money currently sits. If there’s a mismatch, rebalance this month. Sinha has rebuilt differently now – Rs 6 lakh in liquid funds, Rs 8 lakh in hybrids for a 4-year goal, Rs 12 lakh in equity for retirement 25 years away. He says, “Not because returns are higher. But because every rupee finally has a job and a timeline.”
