SIP vs Lump Sum: During geopolitical conflicts and financial market instability, investors often face a critical decision about their investment strategy, which is choosing between Systematic Investment Plans (SIPs) and lump-sum investments. Hemant Rustagi, CEO of Wiseinvest, and Viral Bhatt, founder of Money Mantra, while speaking with Zee Business, shared their key insights on how investors should navigate the current market environment.

Hemant Rustagi began by emphasising the inherent volatility of equity markets. “Equity markets are, by nature, volatile. Market ups and downs occur due to a variety of reasons, including geopolitical tensions and economic shifts. Investors must mentally prepare themselves for these fluctuations,” he explained. He highlighted that investors often struggle to implement strategies effectively due to emotional reactions to market movements.

SIPs: A disciplined approach

According to Rustagi, the most effective approach in such conditions is disciplined investing through SIPs. Regular investments in mutual funds allow investors to spread their contributions over time, thereby mitigating the risks associated with short-term market volatility.

“When markets decline, the new investments happen at lower levels, which reduces the average cost and increases potential long-term returns,” he said. He stressed that emotional discipline is key, noting that emotions often drive poor investment decisions. “The biggest enemy of an equity investor is their own emotions. By continuing investments through volatile periods, you can turn fear into opportunity,” he added.

Viral Bhatt elaborated on this concept using the principle of rupee cost averaging. He explained that SIPs allow investors to accumulate more units when prices are low and fewer when prices are high, which results in lower average purchase costs. The investor buys more units when he invests Rs 10,000 monthly, and the fund NAV drops from Rs 50 to Rs 40.

When the NAV reaches Rs 60, investors buy fewer units. This method leads to consistent investment growth because it smooths out short-term price changes, which results in dependable returns and successful wealth accumulation. Bhatt compared this strategy to the tides of the sea, highlighting that both low and high market phases provide opportunities for disciplined investors.

The experts also discussed the role of lump-sum investments. Rustagi noted that lump-sum investments perform best during extended bull markets. “During a sustained upward market trend, a lump-sum investment can outperform SIPs because the investment is fully exposed to the market’s upward trajectory from the start,” he said.

However, he cautioned that markets rarely follow a single, predictable path. Therefore, relying solely on timing the market for lump-sum investments can be risky. He emphasised that combining SIPs with occasional lump-sum investments often provides the best long-term results. This approach allows investors to benefit from both consistent rupee cost averaging and strategic exposure to market rallies.

The discussion also covered real-world portfolio structuring and asset allocation. The 53-year-old investor, who has a current portfolio worth Rs 3 crore, was advised to diversify his assets among flexi cap, mid cap, large cap and multi-asset investment funds. The SIP strategy of investing Rs 50,000 monthly will enable his total money to reach Rs 11 crore after 10 years and Rs 16 to 18 crore after 15 years, based on a 12 per cent compound annual growth rate, experts noted.

Similarly, younger investors like a 34-year-old, with a Rs 15,000 SIP invested across five funds, were encouraged to optimise their portfolio allocation. The experts recommended slight adjustments to improve diversification and simplify tracking, such as combining certain large-cap and multi-cap funds, while reducing exposure to highly thematic or concentrated funds. These tweaks allow investors to maintain flexibility, minimise risk, and maximise long-term growth potential.

Both experts agreed that there is no clear winner between SIP and lump-sum strategies. “The key takeaway is that market timing is extremely challenging. No one can predict the next month’s market movements with certainty. Instead, investors should focus on disciplined, goal-oriented strategies,” Bhatt said. By aligning investments with clear financial goals—such as retirement, children’s education, or buying a home—investors gain clarity and confidence, allowing them to weather market volatility without panic.

Rustagi concluded by emphasising three principles for successful investing: maintaining equity as a core part of the portfolio for long-term growth, following a diversified asset allocation strategy, and investing with discipline and clarity of goals. “Equity is an aggressive asset class, so over-allocating to sector-specific or thematic funds can be risky. A diversified portfolio, disciplined investing, and a clear understanding of your time horizon will ensure that long-term equity investments yield positive returns,” he said.
