More tracked funds increased than reduced their positions in the latest disclosure.
Latest disclosure: August 2026 · Compared with July 2026
Actively managed funds only: held by 18 · 5 increased · 2 reduced · 0 new · 4 exited, of 22 comparable. Index and arbitrage funds move with index flows and hedged spreads.
23 funds that held Indian Oil Corporation in one of these months have no usable disclosure for the other, usually because the August 2026 filing is not in yet. They are left out of the comparison, not counted as unchanged.
July 2026 → August 2026. Which mutual funds changed their disclosed position in this stock?
Direction comes from the disclosed share quantity, adjusted for splits and bonuses, never from portfolio weight: weight also moves with the price. A change under 0.5% of the existing holding counts as stable. Largest share changes first; new positions by size, exits by the size of the position closed.

The same conviction engine as each fund page, run per fund on this stock: a transition counts only when the fund disclosed on both sides and its share quantity moved at least 0.5% of the existing holding. Missing months and corporate actions without a usable ratio break the sequence instead of being bridged. Funds rank by how many comparable transitions moved in the signal's direction, then consistency, then the longest streak, so steady building outranks one large jump. Bars show each fund's disclosed share quantity scaled to its own first holding in the range; hover for real quantities. 56 actively managed funds analysed; 141 index, ETF and arbitrage funds are excluded because index flows and hedged spreads move holdings without a view on the stock.
Last 1 Year. Is institutional ownership in this stock expanding or contracting over time?
Among funds that disclosed every month, tracked mutual-fund holdings increased by 54.4% between Aug 2025 and Aug 2026, while the number of fund holders fell from 45 to 40.
A constant panel of the 57 funds that held this stock at some point and filed a usable disclosure in every month of the window, so changes are not driven by which funds happened to file. Share counts are in each month's disclosed quantity. Months without comparable filings are left as gaps rather than filled in.
Is the latest ownership change broad across funds or concentrated among only a few institutions?
July 2026 → August 2026 · 140 comparable fund portfolios
23 funds held the stock in only one of the two filings on record and are excluded from the denominator rather than counted as stable.
Each month compares funds that filed both that month and the month before. The number of comparable funds changes with filing coverage, so the share view is the fairer month-to-month comparison.
Which mutual funds increased or reduced their exposure to this stock over the selected period?

Select a fund in the diagram to inspect its position.
Every ribbon joins one fund to Indian Oil Corporation; none joins two funds. The diagram shows that some holders reduced this stock while others increased it between Feb 2026 → Aug 2026, not that shares or money passed from one fund to another. Ribbon width is each fund's absolute change in disclosed shares, adjusted for splits and bonuses. Only funds that filed at both ends of the range are compared. The largest moves are drawn; smaller ones are grouped. 125 index, ETF and arbitrage funds are left out, as in Capital Rotation.
