Nifty 50 and Sensex get most of the attention because they're the numbers that make headlines, but they only describe the largest companies on the exchange. Signal Desk also tracks Nifty Midcap 100 and Nifty Smallcap 100 as core headline indices in every report, specifically so a reader can see whether the broader market is moving with the large-caps or diverging from them.
Why the two don't always move together
Largecap indices are dominated by a small number of very large, liquid, heavily-covered companies — banks, IT majors, energy conglomerates. Midcap indices are built from a much wider, less concentrated set of mid-sized businesses. The two groups respond differently to the same news: a rate decision or a global risk-off move often hits largecaps and midcaps on different days, or with different intensity, because the ownership base, liquidity and sensitivity to foreign-investor flows differ between the two groups.
How to actually build the comparison
Open five or six consecutive Signal Desk reports and note the Nifty 50 and Nifty Midcap 100 levels in each. The gap between the two index's cumulative change over that run of sessions is the comparison — no further data or tool is required, because both numbers are already in every single report. A week where midcaps consistently outrun largecaps, or consistently lag them, is more informative than any single day's gap.
- Midcaps outperforming for several sessions in a row often coincides with broader market breadth (more individual stocks advancing) — worth checking against the breadth numbers in the same reports.
- Midcaps underperforming during a period of rising India VIX is a common pattern — risk appetite typically narrows toward larger, more liquid names first.
- A single day's midcap-vs-largecap gap is mostly noise; a week's worth, read together, is the more reliable read.
This is one more reason the daily report is designed to be read as a running series rather than a one-off snapshot — the index levels, sector leadership and breadth for each session sit in the same archived format, so stitching together a week's comparison is a few minutes of reading, not a data-gathering exercise.
Compare this week's Signal Desk reports →Common questions
Which index does Signal Desk use for midcaps?
Nifty Midcap 100, tracked alongside Nifty 50, Sensex, Bank Nifty, India VIX and Nifty Smallcap 100 as one of the core headline indices in every daily report.
Is midcap outperformance always a bullish sign for the broader market?
Not reliably by itself -- it's one useful data point, best read alongside breadth and India VIX from the same sessions rather than treated as a signal on its own.
Does Signal Desk track smallcaps too, not just midcaps?
Yes -- Nifty Smallcap 100 is tracked as one of the same core headline indices alongside Nifty Midcap 100, Nifty 50, Sensex, Bank Nifty and India VIX.
Largecap and midcap indices respond to the same news differently often enough that comparing them over a week, not a single day, is the more reliable way to see whether the broader market is moving with or against the headline Nifty number. Both figures are already in every Signal Desk report, so the comparison takes minutes, not a separate data source.
