Both Nifty 50 and Nifty Midcap 150 are in correction territory in March 2026 — and the numbers are surprisingly similar. The Nifty 50 is approximately 10.9% below its all-time high of 26,373 set on January 5, 2026. Nifty Midcap 150 is about 10.5% below its recent high of 22,650. For most SIP investors, this raises a straightforward question: should I continue where I am, or shift my allocation?
Here is what makes this correction interesting: midcap indices usually fall harder than largecap in risk-off environments. In the 2020 crash, Nifty Midcap 150 dropped 54% against Nifty 50's 38%. In the 2022 correction, it fell 27% vs 17%. In March 2026, they are falling almost identically. That resilience is telling you something about the underlying SIP flow support for midcap funds.
This article uses NSE India index data and AMFI's February 2026 mutual fund data to give you a clear, data-backed answer on where to put your SIP in 2026.
The short answer: If your investment horizon is 7+ years, continue your SIP in both. Nifty Midcap 150 has historically outperformed Nifty 50 by 3–5% per year over long periods — but with higher volatility. The current −10.5% correction is not a reason to stop, switch, or panic.
Where the Indices Stand in March 2026
As of March 25, 2026, here is how each major Indian equity index sits relative to its all-time or 52-week high:
| Index | All-Time / 52-Wk High | Current Level (Mar 25) | % from High |
|---|---|---|---|
| Nifty 50 | 26,373 (Jan 5, 2026) | ~23,500 | −10.9% |
| Nifty Midcap 150 | 22,650 (52-wk high) | ~20,150 | −10.5% |
| Nifty Smallcap 250 | — | — | −13.1% |
The Nifty Midcap 150 maximum correction during this cycle was −14% from ATH — reached at its low point — but has since recovered to −10.5%. That V-shaped partial recovery, driven by continued SIP inflows, is the key data point here.
What is unusual: Nifty Midcap 150 is down roughly the same as Nifty 50. In the 2020 crash, midcap fell 54% vs Nifty 50's 38% — that is 42% worse. In March 2026, the gap is essentially zero. Institutional accumulation via ₹4,003 crore/month in AMFI mid-cap fund SIP flows is providing a meaningful floor.
SIP Returns Compared: 5-Year and 10-Year Data
The short-term correction comparison is just noise. The real question is what these indices deliver to a disciplined SIP investor over 5, 10, and 15 years.
Based on NSE India Total Return Index (TRI) historical data, here are approximate long-term CAGRs:
- Nifty 50 TRI: ~12% CAGR over 10 years
- Nifty Midcap 150 TRI: ~15–16% CAGR over 10 years
A 3% difference in annual return may not sound dramatic. Over 15 years, it is the difference between ₹25 lakh and ₹33 lakh on the same ₹5,000/month SIP — a ₹8.44 lakh gap on ₹9 lakh total invested.
| Horizon | Nifty 50 SIP (~12% CAGR) | Midcap 150 SIP (~15% CAGR) | Extra Corpus (Midcap) |
|---|---|---|---|
| 5 Years | ₹4,08,000 | ₹4,45,000 | +₹37,000 |
| 10 Years | ₹11,50,000 | ₹13,64,000 | +₹2,14,000 |
| 15 Years | ₹25,02,000 | ₹33,46,000 | +₹8,44,000 |
The compounding effect: A 3% extra annual return compounds to ₹8.44 lakh extra on a ₹9 lakh total investment over 15 years. That is a 93% bonus on your invested capital — purely from the midcap premium.

The Volatility Reality
Higher returns come at a cost: midcap funds are significantly more volatile than Nifty 50 index funds. Before allocating more to midcap, understand what drawdowns you are signing up for.
| Metric | Nifty 50 | Nifty Midcap 150 |
|---|---|---|
| 1-year standard deviation (approx.) | 12–14% | 16–20% |
| Max drawdown — 2020 crash | −38% | −54% |
| Max drawdown — 2022 correction | −17% | −27% |
| Current drawdown — March 2026 | −10.9% | −10.5% |
| Recovery time after 2020 crash | ~6 months | ~8–10 months |
Rule of thumb: If a 25–30% portfolio drawdown keeps you awake at night or triggers panic selling, stick to Nifty 50 or a conservative 80/20 split. If you can hold through a −50% midcap correction knowing your SIP is buying more units, the 60/40 or aggressive allocation makes sense.
What AMFI Data Says About Investor Behaviour
The February 2026 AMFI data is one of the clearest signals that India's retail investor base is maturing:
- SIP inflows: ₹29,845 crore — up 15% year-on-year (Source: AMFI India)
- 60th consecutive month of positive equity mutual fund inflows
- Mid-cap fund inflows: ₹4,003 crore in February 2026
- Small-cap fund inflows: ₹3,881 crore in February 2026
- Total mutual fund AUM: ₹82.03 lakh crore — a new high
The FII sell-off that contributed to this correction has not dented domestic retail commitment. If anything, continued SIP buying during a downturn is textbook rupee cost averaging working as intended.
₹29,845 crore of SIP flows in February 2026 — despite a 10%+ market correction. This is the hallmark of a maturing retail investor base that is not fleeing to FDs at the first sign of a drawdown. The institutional memory of the 2020 recovery is doing its job.
The Right Allocation Mix
There is no single right answer — allocation should match your investment horizon and your honest tolerance for drawdowns, not just your aspirational tolerance.
| Investor Profile | Nifty 50 | Nifty Midcap 150 | Rationale |
|---|---|---|---|
| Conservative (3–5 yr horizon) | 80% | 20% | Capital preservation priority; shorter horizon limits recovery time |
| Moderate (5–10 yr horizon) | 60% | 40% | Balanced growth; enough time to recover from midcap drawdowns |
| Aggressive (10+ yr horizon) | 40% | 60% | Maximum long-term compounding; can absorb −50% midcap drawdowns |
For a 60/40 split on ₹5,000/month: put ₹3,000 into a Nifty 50 index fund and ₹2,000 into a Nifty Midcap 150 index fund. Most major fund houses (Mirae, UTI, HDFC, Axis) offer both. Expense ratios on index funds are typically 0.1–0.2% — keep costs low.
What Should You Do With Your SIP Now?
- Continue your existing SIP — do not stop. Stopping a SIP during a correction locks in losses and destroys the rupee cost averaging benefit. The whole point of SIP is buying more units when prices are lower. A −10.5% correction is exactly when SIP is doing its job.
- Consider a step-up SIP if your income allows. Use the step-up SIP calculator to model increasing your SIP by 10% annually. On ₹5,000/month with 10% annual step-up over 15 years at 14% returns, you accumulate nearly ₹65 lakh vs ₹33 lakh on a flat SIP — almost 2x the wealth.
- Do not time the market with a lump sum. March 2026 is not the buying opportunity that March 2020 was (−54% from ATH). A −10% correction is within normal fluctuation. Use the SIP vs lumpsum calculator to see why SIP beats lump sum at current levels.
- If starting fresh: use a 60/40 or 70/30 Nifty 50/Midcap 150 split. This gives you stability of largecap with the compounding kicker of midcap. Revisit the allocation every 3 years as your horizon shortens.
- Calculate your actual projected corpus. Use the SIP calculator with 12% (Nifty 50) and 15% (Midcap 150) assumptions. Track against your actual goal — retirement corpus, home down payment, children's education. SIP without a goal is savings without a plan.
The Verdict
- Both indices are down ~11% — this is a correction, not a crash. A 10–15% pullback from ATH is historically common and not a reason to exit. The Nifty 50 has seen seventeen such corrections since 2000, each followed by new highs.
- Midcap 150 is unusually resilient in this cycle. Institutional accumulation via ₹4,003 crore/month in AMFI mid-cap SIP flows is providing a demand floor that wasn't present in 2020. This is a structural shift in India's retail investor base.
- Long-term SIP in Midcap 150 outperforms Nifty 50 by 3–5% per year. That compounding translates to ₹8 lakh extra on every ₹9 lakh invested over 15 years. The math strongly favours midcap for investors with 7+ year horizons.
- But midcap carries severe drawdown risk in real bear markets. In 2020, midcap fell −54% vs Nifty 50's −38%. Ensure your allocation matches your actual risk tolerance — the one you have at 3am on a bad market day, not the one you have on a rally day.
- The right answer is both, in the right ratio. A 60/40 (Nifty 50/Midcap 150) split for moderate investors gives you the best of both: large-cap stability plus midcap's superior long-term compounding.
