Market cap drops, opportunities rise: What investors can't miss in 2025

The total average market capitalization for January-June 2025 stood at ₹425.5 lakh crore, the second-highest on record, but marked a 7.6% decline from the previous six-month period (July-December 2024

India’s equity market saw its first cooling-off in nearly two years, with overall market capitalization dropping 7.6% in H1 2025. According to recent data from Geojit’s latest Market Cap Categorization Report, investor flows are tilting toward safer largecaps even as smallcaps and IPOs remain attractive for retail investors. With 41 companies changing buckets and several high-profile demergers creating fresh investment avenues, mutual fund investors must recalibrate allocations.    Market-Wide Softness, But Still the Second-Highest Cap in History

The total average market capitalization stood at ₹425.5 lakh crore, down 7.6% from the previous six-month block (Jul–Dec 2024), but still the second highest ever recorded. 

Market cap of Largecaps fell by -7.1% ; Midcaps by -7.3% ; Smallcaps by -9.6%.

 

 

Largecaps fell by 7.1%, midcaps by 7.3%, and smallcaps by 9.6%, signaling broad-based pressure, especially in high-beta names.

 

 Largecaps Hold Ground as Defensive Play Gains Steam

Despite the decline, largecaps’ share of total market cap rose to 61.3%, slightly up from 60.9% in the previous half, even though it remains lower than the 63.6% share a year ago

 

This increase in weight, amid falling values, hints at capital rotating toward safety in the face of volatility between October 2024 and February 2025.

 

 Shuffling Between Categories: 41 Companies Change Status

10 midcaps graduated to largecap status, while 11 largecaps were downgraded — indicating a churn driven by sharp valuation corrections.

 

9 smallcaps moved up to midcap, while 11 midcaps fell into the smallcap bucket, a sign of compression in the middle of the curve

 

 IPO and SME Surge Keeps Smallcap Momentum Alive

34 IPOs in H1 2025 contributed ₹1.59 lakh crore to market capitalization. Of these, 71% (33 IPOs) were smallcaps, with at least 29 of them in the microcap segment (rank >500), raising ₹46,600 crore.

 

7 SME companies migrated to the main board, contributing ₹8,800 crore in market cap, all in the smallcap bracket

 

 Microcaps: A Quiet but Active Corner

17 companies jumped from microcap (rank >500) to smallcap (rank <500), but 25 smallcaps fell into the microcap bucket due to price erosion or demergers

 

While this segment remains under the radar for institutions, retail investors continue to be drawn to it for its perceived upside potential.

 

Sectoral Movement and Demergers Add to Market Dynamism

Nearly 10 prominent demergers added ₹1.84 lakh crore to the market cap. Notable among these were Siemens Energy (largecap), ITC Hotels (midcap), and AB Lifestyle Brands, Onesource Pharma (smallcaps)

.

These events not only created new investment opportunities but also led to category reshuffles and index realignments.

 

 Entry Thresholds: Steeper Ladders in Every Category

Largecap threshold: ₹91,572 crore (↓8.5% in 6 months, ↑8.6% YoY)

 

Midcap entry: ₹30,756 crore (↓7.4% in 6 months, ↑11.6% YoY)

 

Smallcap floor: ₹10,299 crore (↓9.2% in 6 months, ↑12.1% YoY)

.

Investors in mid and smallcap mutual funds should track these thresholds to anticipate likely reclassifications in July 2025. 

Why this matters:  Mutual fund investors—especially those invested in midcap or smallcap schemes—should take note. AMFI’s biannual stock reclassification, used by mutual funds to align their portfolios, has seen:

 

10 midcap stocks promoted to largecap

 

9 smallcap stocks elevated to midcap

 

11 largecaps demoted to midcap

 

11 midcaps pushed down to smallcap

 

These movements can trigger rebalancing in mutual fund portfolios, which in turn may impact your scheme’s NAV and volatility. If you're holding smallcap-heavy funds, this might be a good time to reassess your risk appetite.

 

What Should  Investors Do?

Reassess fund allocation in smallcap and midcap schemes. While the correction was broad-based, valuations have cooled and some funds may be better positioned post-rebalancing.

 

Look for defensive largecap exposure, especially if nearing a financial goal. The category has shown relative resilience.

 

Explore select IPO plays — many high-quality smallcaps are entering through this route, and mutual funds are beginning to capture these listings.

 

Track demergers and spin-offs, especially in the mid- and smallcap universe. Some of these new entities may enter mutual fund portfolios post-rebalancing.
