Alongside this, the monthly A SIP is a method of investing a fixed amount in a mutual fund scheme at regular intervals, usually monthly, by automatic bank debit. Read the full meaning of SIP contributions have not slowed down. AMFI data for August shows a record Rs 32,297 crore coming in through SIPs, so families and individual investors are continuing their regular monthly contributions even when the index is lower than it was at the start of the year.
This is the reason a review at the end of the year is being looked at differently by many investors. A portfolio that receives money every month, mostly in equity funds, will keep changing in its composition even when the investor makes no new decision. The share of equity, the share of small and mid cap funds and the share of debt can all move away from what was planned at the start of the year, and the movement is often noticed only when the statement is opened.
A review of this kind is therefore a check on the present composition of the portfolio, and the fund with the highest return is not the main point of such a review. Drift in allocation is what such a review is designed to find.
A pass of around 30 minutes usually covers five checks: the asset mix against the target, the weight of small and mid cap funds, the overlap among the funds held, the share of debt and gold, and the SIP amounts along with the goals they are meant for. Each of these takes only few minutes when the statements are kept ready, and the sections below describe what the August fund flow data shows and how the checks are commonly carried out.
What August's fund data says investors are doing
Equity mutual funds received net inflows of Rs 29,328.62 crore in August, as per AMFI data reported by Outlook Money. This is an increase of 18.75% from Rs 24,697.39 crore in July, so more money reached equity schemes even in a month when the index was lower.
The larger part of this money came through SIPs. It shows that regular monthly contributions are now the main source of money for these schemes, and lump sum investments are a smaller part.
The record SIP figure of Rs 32,297 crore mentioned earlier is 14.3% higher than the Rs 28,265 crore recorded in August 2025. Year on year, therefore, the monthly amount has increased by a clear margin.
The number of contributing SIP accounts has also crossed 10 crore for the first time, at 10.02 crore, according to AMFI and Crisil data reported by Anuj Devashrayee on Substack. Equity funds have logged their 66th straight month of positive net inflows which means the flow has continued through several rises and falls of the market.
Within equity, the money is moving towards the smaller segments. Small cap funds led the inflows in August, and small cap and mid cap funds together drew more than half of the total, as per Substack and Outlook Money reports based on AMFI data. Large cap funds recorded a net outflow of Rs 1,147 crore.
Investors who hold a mix of large, mid and small cap funds are therefore adding more to the riskier parts of portfolio every month, whether this is planned or not. The same pattern is visible in the industry numbers, where the combined weight of the smaller segments in fresh money is now higher than that of the large caps.
The size of the industry has grown along with these flows. Total assets under management (AUM) rose 1.5% in August to Rs 87.08 lakh crore, according to the same Substack report. Assets held through SIPs stood at Rs 18.62 lakh crore which is about 21.4% of the total.
For an individual investor, these are industry figures and not a picture of any single portfolio. However, they explain why many families are finding that the proportion of small and mid cap funds in their statements has changed since January, even though they have not placed any new order apart from the monthly instalment.
The 30-minute pass, step by step
Reviewers who follow a short routine usually divide the time among five checks, and the minutes given below show the usual spread of the half hour.
- Asset mix against the target (8 minutes): Investors add up the value of equity, debt, gold and cash across all folios, and then compare the share of each with the split they had planned. The difference between the two is the drift, and it is usually the first number noted down.
- Weight of small and mid cap funds (6 minutes): After the recent flows, many investors look at how much of the equity part now sits in small and mid cap schemes, since regular instalments keep adding to these funds.
- Overlap among funds (6 minutes): Holdings of the different schemes are placed side by side, and investors note the same companies appearing in more than one fund, which can make a portfolio of many funds less spread out than it looks.
- Share of debt and gold (5 minutes): Hybrid funds drew Rs 10,045.34 crore in August, as per Outlook Money, and gold An exchange traded fund is a mutual fund scheme with units listed on a stock exchange, built to follow an index or an asset such as gold. Read the full meaning of ETF took in Rs 2,597 crore, according to Anuj Devashrayee on Substack. Debt funds, however, saw a net outflow of Rs 8,127 crore, against an inflow of about Rs 1.88 lakh crore in July. Investors holding these categories are checking whether their own share has moved in the same direction.
- SIP amounts and goals (5 minutes): Each monthly instalment is matched with the goal it was started for, such as a child's education or retirement, and families note whether the amount and the end date still suit that goal.
The time for each step depends on how many funds a family holds, and a portfolio spread over many folios will naturally need more than 30 minutes.
The checklist above covers what is looked at, and the order in which reviewers move through it is also fairly settled, most of them begin with the asset mix, since the other four checks depend on the drift found in that first step. Investors commonly use the consolidated account summary downloaded from the registrars, and it lists every folio in one place.
Many investors are maintaining a simple sheet with three columns, which carry the planned share, the present share and the difference between the two. The same sheet will be carried forward to the next review, and the movement from one year end to the next year end can then be seen without doing the calculation again.
For the fund overlap step, the portfolio overlap tools offered by several fund platforms are used. These tools display the common holdings of two or more schemes in percentage terms, and investors usually write down the pairs of schemes with the highest common share.
The step on debt and gold is read along with the flow data. The fall in debt fund money after a very large July inflow shows that institutional and retail allocations in this category can change quickly from one month to the next. Hybrid funds and gold ETFs continued to receive money in August, and families holding only equity funds are finding that their own statements carry little of either.
The final step, on SIP amounts and goals, is the one that many reviewers are found to leave incomplete. Matching a monthly SIP with a goal requires the investor to recall the target amount and the year in which it is needed, and a number of folios are found to have been started without either being written down. Reviewers then record both against each folio.
Once the five checks are done, the notes are saved with the date. Any change in the SIP amount or fund mix is usually made after the review has concluded and not during the 30 minutes, and the figures noted will remain as the record of the portfolio on that date.
What the numbers cannot show
The AMFI data now runs up to September. Whatever investors did with their SIPs and lump sum amounts in October is not yet part of any published industry figure.
Fund flows are also a record of money coming in, and they do not show what the schemes earned for the investors. A scheme can receive a large inflow in a month and still show a lower value in statement at the end of that month. The flow figures and the earnings of the schemes are reported separately, and a review of drift in allocation does not depend on the earnings figure.
The net outflow from large cap funds and the lead taken by small cap funds are best read as a pattern seen in one month of data. They show the schemes where the new money went in August and they say nothing about the shift for any individual family. Individual portfolios differ in size, in the age of the folios and in the goals attached to them, and the industry pattern will therefore be seen clearly in some statements and very little in others.
Investors who carry out a review at this time of the year are working with the statements in their own hands and the industry data serves only as a background to those statements.
The October picture will become clear only when AMFI publishes its next monthly release, as the data now available stops at September.
