Only 2 of 23 Mutual Fund Themes Gained in August; IPO and Defence Stay Green as Auto, Railways and Tech Slide

Only Two Mutual Fund Themes Gained in August

The Indian equity market faced broad-based pressure in August 2026, with only two of 23 mutual fund themes ending the month in positive territory, according to a report by Vallum Capital.

The IPO and defence themes were the only ones to post gains during the month. IPO-focused funds rose 2.2%, while defence-themed funds gained 1.4%.

The performance came against a backdrop of a 2.1% decline in domestic equities during August, indicating that investors were increasingly selective about where they deployed capital.

At the other end of the spectrum, automobile, railway and technology-related themes recorded some of the steepest declines.

The figures show that the weakness was not uniform across every part of the market. Some specialised themes continued to attract investor interest even as broader equity markets declined.

IPO Funds Remain in the Green

IPO-themed mutual funds were among the few categories to deliver positive returns in August.

The theme gained 2.2% during the month and received approximately Rs 37 crore of inflows.

The performance suggests that investor interest in companies and businesses associated with the IPO ecosystem remained relatively resilient during a month when many other equity themes struggled.

However, a one-month gain does not necessarily indicate a sustained trend. Theme-based mutual funds can be highly sensitive to valuations, market sentiment and the performance of their underlying stocks.

Defence Funds Gain 1.4%

Defence emerged as the second positive mutual fund theme in August, gaining 1.4%.

Defence-oriented funds also attracted approximately Rs 235 crore in inflows during the month.

The combination of positive performance and fresh fund flows indicates that investors continued to allocate money toward the defence theme despite broader equity-market weakness.

However, investors should distinguish between a theme's recent market performance and its longer-term investment prospects. Sectoral and thematic funds can have concentrated exposure and may therefore experience greater volatility when market conditions change.

Auto Funds Among the Biggest Laggards

The automobile theme was one of the weakest performers in August, declining 6.5%.

Despite the fall, auto-focused funds received approximately Rs 244 crore in inflows.

This divergence between performance and flows is notable. Investors continued putting money into the theme even though the underlying segment recorded one of the largest monthly declines among the 23 themes tracked in the report.

The data illustrates why fund flows and investment performance do not always move in the same direction. Investors may continue investing through SIPs or make fresh allocations even during periods of negative performance.

Railway Funds Fall 6.4%

Railway-themed funds also experienced significant pressure in August, declining 6.4%.

Despite the decline, railway-focused funds recorded around Rs 22 crore in inflows.

The railway theme had been closely watched by investors because of its exposure to companies linked to infrastructure and government capital expenditure. However, the August performance indicates that thematic momentum weakened during the month.

As with other thematic investments, short-term performance can be influenced by valuations, profit expectations and changes in investor sentiment.

Technology Funds See Sharp Decline and Outflows

Technology was another major laggard during August, falling 6.1%.

Unlike auto and railway funds, however, the technology theme also experienced a significant withdrawal of investor money.

Technology-focused funds recorded an outflow of around Rs 523 crore during the month.

The report also pointed to a sharp divergence within the broader technology segment. While the technology theme declined, Internet & Digital gained 3.2%, whereas the IT Index fell 9.1%.

This suggests that technology-related investments did not move uniformly and that investors were differentiating between different segments of the broader technology universe.

Consumption Theme Falls 4.5%

The consumption theme declined 4.5% in August and recorded an outflow of approximately Rs 357 crore.

Consumption-focused funds can be influenced by factors such as household spending, inflation, interest rates and corporate earnings expectations.

The August decline, combined with fund outflows, indicates weaker investor appetite for this particular theme during the month.

Healthcare and Business Cycle Themes Also Decline

Healthcare and business-cycle themes performed better than some of the major laggards but still ended August in negative territory.

Healthcare declined 0.8%, while the business-cycle theme fell 1.5%.

The energy theme declined 1.8% and still received approximately Rs 18 crore in inflows.

The commodities theme declined 1.6% in August, but it remained one of the strongest performers on a year-to-date basis.

Equity Fund Inflows Drop Sharply

The weakness in thematic performance was accompanied by a substantial slowdown in equity mutual fund inflows.

According to the Vallum Capital report cited by Economic Times, equity fund inflows fell from Rs 45,325 crore in July to Rs 31,326 crore in August.

That represents a decline of nearly Rs 14,000 crore in a single month.

The reduction suggests that investor risk appetite in equity funds moderated during August as market conditions became more challenging.

The data shows that flows weakened across several categories, while commodity-related inflows increased during the month.

Money Market Inflows Also Moderate

Money market funds continued to attract money in August, but inflows fell sharply from the previous month.

Inflows dropped from Rs 1,46,677 crore in July to Rs 43,407 crore in August.

Although the category continued to see positive flows, the reduction indicates that investors were not moving money into money-market products at the same pace as in July.

Fixed Income Sees Outflows

Fixed-income funds moved from an inflow of Rs 6,212 crore in July to an outflow of approximately Rs 1,468 crore in August.

This change indicates a shift in investor positioning within the broader mutual-fund market.

However, monthly fund-flow movements can be affected by a range of factors, including interest-rate expectations, portfolio rebalancing, redemptions and institutional allocations.

Commodities Remain Strong on a Year-to-Date Basis

Commodities were among the most notable performers when measured over the year-to-date period.

Although the commodities theme declined 0.5% in August, it delivered approximately 12% on a year-to-date basis, according to the report.

That compared with a 1.4% YTD return for equities.

Commodity-fund inflows also increased from Rs 4,081 crore in July to Rs 4,800 crore in August.

This indicates that investors continued to allocate money to commodities despite the theme's marginal monthly decline.

Smaller Companies Show Relative Resilience

The August market weakness was also not evenly distributed according to market capitalisation.

The report showed that Micro-Cap gained 2.6%, while the Small-Cap segment was marginally positive.

By comparison, Large-Cap declined 4.1%.

This divergence suggests that the market correction did not affect all company-size segments equally.

It also highlights the importance of looking beyond broad market indices when assessing mutual-fund performance. Different funds can experience substantially different returns depending on their portfolio construction and market-cap exposure.

What the August Data Means for Mutual Fund Investors

The August data highlights the risks associated with investing purely on the basis of a sector or theme.

While IPO and defence funds delivered positive returns during the month, several other themes suffered declines of more than 4%.

This wide variation demonstrates that thematic funds can behave very differently from diversified equity funds.

Investors evaluating thematic or sectoral funds should therefore consider:

• The fund's investment objective

• Concentration of the portfolio

• Valuation of underlying companies

• Historical volatility

• Fund performance across different market cycles

• Expense ratio

• Investment horizon

• Risk tolerance

• Existing exposure to the same sector

A strong one-month return should not by itself be treated as evidence of future performance.

Fund Flows and Returns Can Tell Different Stories

One of the most interesting aspects of the August data is the difference between fund performance and fund flows.

Auto funds declined 6.5%, yet received Rs 244 crore of inflows.

Railway funds fell 6.4% but still received Rs 22 crore.

Meanwhile, technology funds declined 6.1% and recorded a much larger Rs 523 crore outflow.

This demonstrates that investors' buying and selling decisions can differ substantially from the direction of market returns.

Fund flows may reflect SIP contributions, portfolio rebalancing, new investment decisions or redemptions, and therefore should not be interpreted as a standalone indicator of future performance.

The Technology Theme Shows Internal Divergence

The technology data is particularly notable because the broad technology theme fell 6.1%, while Internet & Digital gained 3.2%.

The IT Index also declined sharply, falling 9.1%.

The divergence suggests that grouping all technology-related companies into a single investment category can hide substantial differences in performance.

For investors, this means that the underlying portfolio and exact investment mandate of a thematic fund matter considerably.

Should Investors Move Into the Themes That Stayed Green?

The August performance does not by itself establish that the IPO or defence themes will continue to outperform.

Similarly, a decline in auto, railway or technology funds does not automatically mean those themes will remain weak.

Thematic investing carries concentration risk because a fund may have substantial exposure to a relatively narrow set of industries or companies.

Investors should therefore assess whether a particular theme fits their overall asset allocation and investment horizon rather than basing decisions solely on a single month's performance.

Broader Market Picture

The August numbers point to a market environment characterised by weaker equity performance, lower equity-fund inflows and significant differences between individual themes.

Domestic equities declined 2.1% during the month, while money-market assets were the only major asset class in the report to deliver a positive monthly return, at 0.5%.

Fixed income was flat during August and delivered a 3.7% YTD return.

Commodities, despite their monthly decline, remained the strongest performer on a YTD basis.

Bottom Line

The August 2026 mutual-fund theme performance showed a sharp divergence across India's equity market.

Of the 23 themes tracked by Vallum Capital, only IPO and defence posted positive returns, gaining 2.2% and 1.4%, respectively.

Auto and railways were among the biggest losers, declining 6.5% and 6.4%, while technology fell 6.1%. Technology funds also recorded an outflow of Rs 523 crore, even as auto and railway funds continued to receive fresh inflows.

The report also highlighted a broader slowdown in equity-fund inflows, while commodities remained strong on a year-to-date basis and smaller-company segments showed relative resilience.

For mutual fund investors, the August data reinforces the importance of looking beyond one-month returns. Theme concentration, valuations, fund flows, portfolio composition and investment horizon can all influence outcomes. A theme that performs well in one month may not necessarily deliver the same result in subsequent periods.
