India's only actively managed mutual fund dedicated to the defence sector made deliberate portfolio moves in March, adding shares across six existing positions, welcoming one new entrant, and fully exiting one stock — all while keeping its total holding count steady at 22. Data from ACE MF shows that HDFC Defence Fund, launched in June 2023 and benchmarked against the Nifty India Defence TRI, has delivered a compounded annual growth rate of 37.42% since inception, underscoring sustained investor appetite for the sector.

Where Fresh Capital Was Deployed

The fund's largest addition in absolute share count was in Aequs, a precision manufacturing company serving aerospace and consumer segments. The fund increased its Aequs position by 10.51 lakh shares, bringing the total to nearly 17.68 lakh shares — a significant concentration of conviction in a company that straddles both defence supply chains and broader industrial manufacturing.

Hindustan Aeronautics Limited received an addition of 50,000 shares, lifting the total to 25.50 lakh shares. HAL now carries an allocation of 12.18% of net asset value, making it one of the fund's larger individual positions. Given HAL's central role as India's primary state-owned aerospace manufacturer — responsible for producing military aircraft, helicopters, and aero-engines under both licensed and indigenous programmes — the addition reflects continued confidence in order-book visibility and long-term government procurement cycles.

Eicher Motors, which might appear an unconventional name in a defence-themed fund, was bolstered by 45,000 shares, taking the holding to 4.95 lakh shares. The inclusion fits within the fund's Automobiles and Ancillaries allocation, which accounts for 21.69% of the portfolio. Defence logistics, military vehicles, and ancillary transport requirements have historically drawn in commercial vehicle manufacturers, and Eicher's exposure to specialised mobility solutions gives it a foothold in defence-adjacent demand.

Smaller additions were made across Bharat Electronics (2.70 lakh shares), Solar Industries (approximately 22,672 shares), and Bosch (7,151 shares). Despite being modest in share count, the Solar Industries addition is notable: the company is India's largest manufacturer of industrial explosives and has expanded aggressively into defence-grade ammunition and propellants, and it already carries a 10.54% allocation in the fund.

A New Name Enters, One Exits

Sedemac Mechatronics joined the portfolio as a fresh entrant, with 3.97 lakh shares acquired at a market value of approximately Rs 60.15 crore. Sedemac is a Pune-based engineering company specialising in embedded control systems, engine management technologies, and precision electronics — areas with clear application in defence platforms, unmanned systems, and advanced propulsion management. Its addition signals the fund managers' willingness to include smaller, technology-intensive firms that supply enabling components rather than finished defence platforms.

Avalon Technologies, on the other hand, was fully exited in March. All 1.33 lakh shares were sold, representing a market value of Rs 13.64 crore at the time of disposal. The fund provided no publicly stated rationale for the exit, but a complete divestment — rather than a partial reduction — typically reflects a reassessment of either valuation, business trajectory, or strategic fit within a thematic portfolio.

Portfolio Composition and What It Reveals

The fund's sector spread across seven categories tells a deliberate story. Capital Goods dominates at 52.68%, consistent with the weight of defence hardware, electronics, and engineering in India's defence industrial base. Automobiles and Ancillaries at 21.69% reflects the fund's broader interpretation of "allied sector" — encompassing mobility and logistics infrastructure. Chemicals, largely driven by Solar Industries, holds 12.94%.

By market capitalisation, the fund maintains a balanced but growth-oriented mix: 50.38% in largecaps, 25.14% in smallcaps, and 19.77% in midcaps. The smallcap exposure is notably elevated for a sector fund, which heightens both the return potential and the volatility risk. Investors in thematic funds such as this one are generally expected to carry a higher tolerance for drawdowns in exchange for concentrated sectoral upside.

The top allocation by NAV belongs to Bharat Electronics at 18.70%, followed by Bharat Forge at 15.27%. Both are established names with deep integration into India's defence procurement ecosystem — BEL supplies radar, electronic warfare systems, and communication equipment, while Bharat Forge has pivoted substantially toward artillery, armoured vehicle components, and aerospace forgings. Together, they account for roughly a third of the fund's value.

The Broader Context: India's Defence Ambitions and Fund Strategy

HDFC Defence Fund operates against a policy backdrop that has materially shifted in India's favour. The government's sustained push toward indigenisation — channelled through mechanisms such as positive indigenisation lists, increased defence capital expenditure, and the Defence Acquisition Procedure framework — has structurally expanded the addressable market for domestic manufacturers. This policy momentum is the primary engine driving thematic interest in defence-focused investment vehicles.

The fund's one-year return of 31.53% and a three-month return of 4.37% suggest that while the longer arc remains strong, near-term performance has moderated — a pattern common to thematic funds when valuations outpace earnings delivery in the short run. Managed by Rahul Baijal and Priya Ranjan, the fund's March moves indicate an intent to deepen quality holdings rather than reshuffle broadly, with a preference for adding to positions where business fundamentals or order pipelines justify higher exposure.

For investors, the key consideration remains concentration risk. A fund invested entirely within one sector — even one with strong government tailwinds — carries inherent sensitivity to policy changes, procurement delays, or geopolitical shifts. The inclusion of companies like Eicher Motors and Bosch, which have significant non-defence revenues, offers a degree of indirect diversification within the thematic mandate. Whether that is sufficient buffer depends entirely on how India's defence spending trajectory holds over the next decade.
