As geopolitical headwinds make it tougher for equity investors to make money, Dalal Street’s top voice Nilesh Shah, managing director of Kotak Mahindra Asset Management, told a gathering of HNI investors at the ET Alpha Wealth Summit on Thursday that there are four specific investment structures which deserve a place in most portfolios right now.Shah’s first recommendation was the Special Investment Fund, or SIF, a structure that marks a meaningful shift in what is available to Indian investors. Shah noted that the mutual fund industry has, until now, been a long-only business but the SIF changes that. These are long-short, absolute return-oriented funds, designed to generate returns regardless of market direction rather than simply riding the equity tide.The second vehicle Shah flagged is performing credit AIFs. His reasoning was grounded in a simple supply-demand observation that for corporate settlements today, capital is not available from banks, mutual funds, or insurance companies.As institutional lenders have stepped back, borrowers are plenty and lenders very few. Amid this imbalance, Shah said the need is real and returns are attractive. Performing credit AIFs, which lend into this gap, are positioned to benefit directly from the scarcity of competing capital.The third idea was REITs, and here Shah introduced a timing element. Over the last three years, REITs have delivered index-level returns of around 13.5%. But with interest rates rising, he suggested that the next six to nine months may present an opportunity to enter at better prices. Rising rates typically compress REIT valuations in the near term, and Shah framed any such correction as a potential entry point rather than a risk to avoid. Beyond the return potential, he positioned REITs as a portfolio diversification tool as the asset class behaves differently from equities and fixed income, and that is still underrepresented in most Indian investor portfolios.The fourth recommendation addressed global diversification but came with an important caveat. Mutual fund industry limits for overseas investment are currently full, which means the conventional route for Indian investors to access global markets through domestic mutual funds is closed. Shah pointed to Gift City as the workaround. Structures domiciled there allow investment under the Liberalised Remittance Scheme, and in his view, these Gift City-based LRS products are the practical path for investors who want global exposure while the mutual fund window remains shut.Across all four — the SIF, performing credit AIFs, REITs, and Gift City products — Shah's underlying argument was the same: in a volatile period, the portfolio needs instruments that can generate positive returns through means other than a rising equity market.(Disclaimer: Recommendations, suggestions, views, and opinions given by experts are their own.
