What is net flow?
Every month investors put money into funds through SIPs and lump sums, and take money out through redemptions. Net flow is the difference: inflows minus outflows. When it is positive, the category took in more than it paid out. When it is negative, it shrank by that amount through redemptions alone.
Net flow is not the same as the change in a fund’s AUM. AUM also moves with markets: when stocks rise, AUM rises even if nobody invests a rupee. Net flow isolates what investors actually did, which is why it is the cleaner measure of sentiment.
Net Flow = Gross Inflows − Redemptions
Change in AUM = Net Flow + Market Appreciation (or depreciation).
Real net flows, September 2026
In September 2026, equity categories together took in +₹38,307 Cr, while debt funds saw −₹1,83,565 Cr. The category split shows where equity money went:

Debt flows swing far more than equity flows. Money market and liquid funds are used by companies and institutions as short-term parking for cash, so large debt outflows often reflect treasury movements, such as paying advance tax, rather than investors losing faith in debt funds. Read equity and debt net flows separately.

The pattern across months
Over the 5 months in Flow Watch, equity categories had positive net flow in 5 of them, adding up to +₹1,44,214 Cr. The strongest month was September at +₹38,307 Cr and the weakest was May at +₹22,908 Cr. Debt was net negative in 4 of the 5 months, with a cumulative −₹2,11,866 Cr. The two behave very differently: equity flow is steady and fed by monthly SIPs, while debt flow lurches with corporate cash needs.
Net flow also feeds into size. A category that takes in ₹9,039 Cr in a month, as Small Cap did in September 2026, adds that much to fund assets before any market move, and very large inflows can make it harder for fund managers to deploy money in smaller, less liquid stocks.
See Does Inflow Predict Returns? for a real test of whether heavy-inflow categories go on to outperform.
How to read flows
Steady equity inflows through SIPs show long-term investor commitment. Sharp outflows after a market fall often show investors reacting late. Chasing flows is a poor guide to returns: a category with heavy inflows may already have rallied. Net flow tells you where the money has gone, not where it should go.
Frequently asked questions
What is the difference between net flow and AUM change?
Net flow is the new money in minus money redeemed. The change in AUM also includes gains or losses from the market, so a category’s AUM can grow even when its net flow is negative.
Why are debt net flows so volatile?
Liquid and money market funds are used by companies to park short-term cash, so large amounts move in and out around tax dates and quarter ends.
Do high inflows mean a category will do well?
No. Inflows tend to follow past performance, so they say where investors have been, not where returns will go.
WHAT THIS MEANS FOR YOU Do not buy a category just because it has the highest inflow. Flows follow performance, they do not predict it. Use net flows to understand market mood and to spot when a fund is growing so fast that its size could become a constraint, then judge the fund on its own record.
