Sensex, Nifty August returns: 11-year data shows mixed trend

Mumbai: As the market steps into August, traders and investors are once again looking at history for clues. The question doing the rounds: will the bulls repeat their past performance this month?

A look at the last 11 years of data shows that August has been a mixed bag for Indian equities. The Sensex and the Nifty have ended the month in the green in six of those 11 years. That gives bulls a slight edge, but only just.

What the numbers say

The average return for the Sensex in August over this period stands at about 1 per cent. The Nifty has behaved similarly. But averages can be misleading. Some Augusts have delivered sharp gains, while others have seen painful declines.

For instance, in certain years, the month brought gains of over 4 per cent. In others, losses of similar magnitude have been recorded. The data suggests that August is not a month of smooth sailing, but one where direction is decided by external triggers as much as domestic fundamentals.

Key factors that could shape August

Several factors are likely to influence the market this time around. Global cues remain a major driver. Movement in US bond yields, crude oil prices, and the dollar index will be watched closely by domestic institutions.

On the domestic front, the progress of the monsoon and its impact on inflation will be tracked. Any shock on the inflation front could alter expectations around the Reserve Bank of India's rate trajectory.

Foreign portfolio investor flows have also been a key determinant in recent months. A continuation of buying by FIIs could provide support, while any reversal could add pressure.

What the past suggests

Historical patterns offer limited comfort. The data shows that while positive months have been more frequent, the magnitude of gains in those months has not always been large. The distribution of returns is wide, with the market often moving sharply in one direction before settling.

Technical analysts point out that the indices are trading near key levels. A breakout above those levels could invite fresh buying. A failure to hold support, on the other hand, could trigger profit booking.

Options data, too, suggests that traders are positioning for range-bound movement initially, with a bias towards the upside. But that positioning can change quickly if global sentiment sours.

The road ahead

For now, the market appears to be in a wait-and-watch mode. The first few sessions of August will likely set the tone for the rest of the month.

Investors would do well to keep an eye on the weekly expiry data and the movement of the rupee. These are often early indicators of where the market is headed.

As always, the past is not a guarantee of the future. But for those looking for direction, the 11-year data provides a useful backdrop. The coming weeks will show whether history repeats, or whether the market writes a new chapter.
