The big story

Not so long ago, India's Nifty 50 index was outperforming the S&P 500 for this year.

But an 8% rally in U.S. stocks since the big Aug. 5 sell-off has left the Indian benchmark in the dust.

While much of the American outperformance can be credited to markets realizing the U.S. economy remains strong, the lackluster performance of Indian equities has been chiefly due to its failure to positively surprise investors.

Earnings for Nifty 50 companies rose 3% in the first quarter over the past year. Stripping out banks and energy firms shows that the rest eked out earnings-per-share growth of 19% in the most recent quarter, compared to a year ago.

However, the stock market is a forward-looking beast, and the above was expected. In fact, only 21 out of the 50 companies that make up the index surprised investors. The rest simply couldn't keep up.

Many analysts fear it won't be long before nearly all of the market fails to outperform expectations. And even when a few companies do, it won't matter much for investors' total returns.

"We believe that potential beats in Autos, Industrials, Healthcare, and IT may not be enough to offset the misses in Financials, Metals, and Energy," said Amish Shah, equity strategist at Bank of America. "Besides, slowing global growth is a risk."

A possible slowdown in global economic growth, potentially leading to a fall in commodity prices, isn't helpful for India. But it's unlikely to derail its growth trajectory.

The South Asian nation has a consumer-led economy where exports aren't yet a dominant feature. However, a fall in oil prices due to a global slowdown could prove beneficial as lower fuel prices contribute to higher discretionary spending for its citizens.

Since the stock market isn't representative of the Indian economy — energy makes up a significant portion of the Nifty 50 while being a relatively small portion of the GDP — any hit to oil and gas firms' earnings leaves investors with wobbling returns. GDP growth, meanwhile, might continue to stay the course.

Investors have also raised the bar for future growth with lofty projections. To meet expectations, Nifty 50 companies' earnings per share would need to grow by 13% compounded annually for three years, according to Citi. This is a tall order, yet tepid from even frothier previous expectations.

"Earnings revision, though still better than long-term trends, have moderated from upward revision trends and now are flattish since July," said Surendra Goyal, head of India research at Citi. "We find upsides limited at current levels — would be buyer on any dips."

Should investors sell out? Is it worth risking future potential profits?

One cadre of investors think they may have solved the conundrum by turning toward a more stable instrument: bonds.

"Indian equities are enjoying strong price momentum and earnings growth, but remain highly correlated to, and arguably dependent on, the continued performance of US equities in a late cycle environment," said Maximilian Macmillan, a senior investment director at U.K. asset manager Abrdn, told CNBC's Inside India. "Bonds offer diversification from this dominant and singular source of performance, though they are not risk immune."

Data from the National Securities Depository Limited shows that foreign fund flows into Indian bonds have exceeded that of equities so far in 2024. In addition, bond funds have also had net inflows continuously since early 2023, barring one month.

Equities, meanwhile, have seen foreign investors pull money in one out of every four months over the past two years.

"While foreign investor flows in equities are volatile, India is attracting heavier foreign debt inflows owing to the listing of Indian sovereign bonds on global bond indexes," said Shumita Deveshwar, chief India economist at TS Lombard.

Aside from Indian government bonds being included in JPMorgan's emerging market indexes, which has been one of the biggest drivers of fund flows, a diverse availability of India-specific bond funds has also helped.

Actively managed funds such as Abrdn's and Invesco's India bond funds offer well over 7% yield. ETFs from iShares, L&G, and Xtrackers have also made it possible to meet the increased demand for Indian government debt.

"They are one of the very few investment grade asset classes offering yields of around 7% — creating an excellent entry point [for] investors particularly as, unlike many other global bond markets, yields are higher than the Indian policy rate of 6.5% and the latest inflation print of 5.1%," said Kenneth Akintewe, head of Asian debt at Abrdn.
