Stock market this week: Top gainers and losers among small, mid, and large-cap stocks

Market Overview

Broadly, markets in India saw moderate gains. The BSE-500 index rose by about 1.6% over the week.
Around 64% of stocks in the BSE 500 ended the week in the green (i.e. gained) — that’s 319 of the 500 stocks.
The losses among the rest were relatively mild — most losers were restricted to single-digit percentage declines.

Gainers

One of the standout large-caps was Infosys, which made waves after proposing a share buyback, which lifted investor sentiment.
Other heavyweight contributors included names drawn from the Sensex/Nifty 50 that had favorable moves; although precise large-cap top-gainers beyond Infosys weren’t all listed in the sources I found, gains in the Nifty / Sensex were helped by select large firms and good sectoral trends like in IT.

Losers

Among large caps, the losses appear more dispersed and less dramatic. A few Sensex / BSE large-cap names featured among the week’s top losers (BSE large-caps list) though typical losses for large caps tended to be limited.
Some large-caps in sectors that underperformed (consumer goods, pharma, etc.) saw declines. For example, companies like Hindustan Unilever, some pharma names were listed among daily top losers.

Mid-caps had a mixed week. Some delivered very strong returns (even double-digit) but many underperformed relative to large caps. There has been more volatility in this segment.
While not all individual mid-cap names are detailed in my sources, the mid-cap index saw positive but modest gains. The sentiment remains cautious: gains are happening when specific companies have favorable news (orders, buybacks, earnings), but broad momentum is not as strong.

Small-caps showed pockets of strong performance. Some small-cap stocks rallied significantly this week — several delivered double-digit returns.
However, there were also more noticeable losers in the small-cap ranks. A fair number of small-cap stocks lost ground, reflecting higher volatility. For instance, in the BSE small-cap list, companies like Moongipa Securities, Go Fashion, Indoco Remedies etc. were among the top losers.

Several factors helped shape the week’s performance:

Corporate actions & news: Infosys’ buyback announcement stood out, helping lift its stock and sentiment in the IT sector.
Global & macro cues: Expectations of interest rate cuts in the U.S., stability in foreign exchange reserves (India’s forex reserves went up) provided tailwinds.
Sectoral rotation: Some sectors like IT, energy, or even infrastructure/orders-driven firms saw more buying. In contrast, more defensive sectors or those with weaker earnings were under pressure.
Risk & volatility: Small and mid caps remain riskier; news flow (orders, regulatory, earnings) tends to move them more sharply both up and down. Investor sentiment is cautious especially in less liquid names.

Here are some of the specific names that stood out this week:

Strong Performers:
- Infosys – boost from buyback proposal.
- Waaree Energies – hit a fresh 52-week high, surged ~8%.
- JBM Auto, Hindustan Copper, Bharat Electronics, etc. – among daily top gainers.
Lagging/Losers:
- Among large caps: Hindustan Unilever, HeidelbergCement India, GlaxosmithKline Pharma, Metropolis Healthcare etc. had declines.
- Small-cap names like Moongipa Securities, Go Fashion, Indoco Remedies appear among worst weekly performers in small cap lists.

The market seems to be in a consolidating phase rather than a strong runaway uptrend. Large caps (especially those with strong news flow) are being rewarded; small & mid caps are more volatile.
Q3 earnings, corporate announcements (buybacks, new orders, margin pressures) could play a big role in who outperforms.
Macroeconomic stability (inflation, interest rate decisions, currency movements) will remain key. Any negative surprises (global or domestic) could hit small & mid caps harder.
For investors: balancing exposure makes sense — large caps for stability; cautiously selecting mid/small caps with strong fundamentals or positive catalysts.
