Sensex Sees Sharp Swings During Closing Auction Session on F&O Expiry Day
The Sensex witnessed sharp volatility during the Closing Auction Session (CAS) on August 27, as the monthly expiry of futures and options (F&O) contracts coincided with the new closing price mechanism introduced by the Bombay Stock Exchange (BSE). The Sensex fell more than 2,200 points within a five-minute period during the CAS before recovering nearly 2,000 points over the following seven minutes. The index eventually closed at 76,934, down 539 points from the previous session. The sharp movement also affected several major Sensex constituents, raising concerns among market participants about volatility during the closing period.
What Is the Closing Auction Session?
The Securities and Exchange Board of India (Sebi) introduced the Closing Auction Session on August 3 as a new method for determining the closing prices of stocks. The mechanism is applicable to around 200 stocks on which equity derivatives contracts are traded. Other non-derivatives stocks continue to use the volume-weighted average price (VWAP) system. The CAS is designed to improve the price discovery process and reduce the scope for manipulation around market closing.
However, since its introduction, the Sensex and Nifty have experienced significant price movements between 3:15 pm, before the auction begins, and 3:30 pm, when the session ends.
Sharp Moves in Major Stocks
The volatility was also visible in some of the largest Sensex constituents.
Reliance Industries, which has the highest weight in the Sensex, fell from around Rs 1,289 to Rs 1,250 during the closing period, representing a decline of about 3% within seven minutes. The stock subsequently recovered to close at around Rs 1,286.
Similar sharp movements were observed in other major stocks, including HDFC Bank, ITC and Bharti Airtel. Such price movements during the final minutes of trading can have a significant impact on derivatives positions, particularly on expiry days when traders are adjusting or closing contracts.
Nifty Also Witnesses Volatility
The National Stock Exchange (NSE) saw comparatively lower volatility during the same period. The Nifty fell by more than 100 points between 3:18 pm and 3:22 pm before recovering around 60 points by the end of the session. The index closed at 24,091, down 117 points from the previous session. The difference in volatility between the two exchanges has drawn attention to the impact of the new closing mechanism and its interaction with derivatives trading.
Market Manipulation Concerns
The sharp movements come amid increased regulatory attention towards potential manipulation in index and stock prices during the closing period.
Earlier in August, Sebi took action against Copthall Mauritius, a JP Morgan entity, over alleged manipulation involving the Sensex and its constituent stocks. The regulator also alleged that Mansi Stock & Share Broking had used a similar strategy in proprietary trades.
Sebi subsequently barred the entities involved from the market and ordered the disgorgement of nearly Rs 3.8 crore in alleged illegal gains.
The introduction of CAS was intended, among other objectives, to strengthen the closing price discovery process and reduce the possibility of manipulation.
What the Volatility Means for Traders
The sharp intraday movements highlight the risks associated with trading derivatives close to the market close, particularly on expiry days.
Large changes in index levels within a few minutes can significantly affect the value of futures and options contracts. While such movements may create opportunities for traders, they can also result in substantial losses when positions move against them.
The recent volatility is likely to keep market participants focused on how the Closing Auction Session performs as it becomes more established and whether the new mechanism results in more stable and reliable closing prices over time.

SIP Built Your Corpus. SWP Decides How Long It Lasts
Retirement planning is usually about one big question: How much money do I need to retire?
But once you actually retire, another question becomes just as important:
How much can I withdraw without running out of money?
This is where a Systematic Withdrawal Plan (SWP) can become an important part of your retirement strategy.
An SWP allows you to withdraw a fixed amount from your mutual fund investments at regular intervals, while the remaining corpus stays invested. But unlike a pension, an SWP does not guarantee income for life. Your money remains exposed to market movements, inflation and other risks.
First, calculate your actual income gap
Don’t start with a random withdrawal number.
Start with your expenses.
Add up your essential monthly costs – household expenses, healthcare, insurance, utilities and other regular needs. Then subtract income you already have from sources such as a pension, rent or other investments.
The gap is what your SWP needs to cover. For example, if your retirement expenses are ₹70,000 a month and you receive ₹30,000 from other reliable sources, your portfolio needs to generate the remaining ₹40,000.
That number should drive your withdrawal strategy – not simply what feels comfortable today.
How much can you withdraw?
Suppose you retire with a ₹1 crore corpus and withdraw ₹40,000 every month.
That is ₹4.8 lakh a year, or an initial withdrawal rate of 4.8%.
Whether that money lasts depends on several factors – investment returns, inflation, how long you need the corpus and whether your withdrawals increase over time. There is no single withdrawal rate that works for every retiree.
The bigger the withdrawal, the greater the pressure on your corpus.
The biggest risk may come early
Imagine you retire and the market falls sharply in your first year.
You still need your monthly income, so you continue withdrawing money while your investments are down.
You may now have to sell more units to generate the same amount of cash.
This is known as sequence-of-returns risk – and it can seriously affect how long your retirement corpus lasts.
One way to manage this is to keep some money in relatively safer or liquid investments for near-term expenses, reducing the need to sell growth-oriented investments during a market downturn.
Inflation doesn’t retire with you
A ₹50,000 monthly expense today won’t necessarily remain ₹50,000 five or ten years from now.
Healthcare, household costs and everyday living expenses can rise with inflation.
That means your retirement plan needs to account for rising expenses, rather than assuming today’s spending will remain unchanged.
Your SWP should therefore be reviewed periodically instead of being treated as a set-it-and-forget-it strategy.
Don’t ignore taxes
An SWP isn’t simply “withdrawing your own money”.
Each withdrawal involves the redemption of mutual fund units. The taxable portion is generally the capital gain arising from the units being redeemed, with the applicable tax depending on the fund type, holding period and prevailing tax rules.
So your retirement strategy isn’t just about how much you withdraw.
It is also about how you structure your investments and withdrawals.
The bigger retirement lesson
Building a ₹1 crore or ₹2 crore corpus may feel like the finish line.
It isn’t. Accumulation is one part of retirement planning. Decumulation – deciding how to use that money – is the other.
A good retirement strategy needs to answer four questions:
How much will I need?
How much can I withdraw?
Where should the remaining money stay invested?
How often should I review the plan?
Because the goal isn’t simply to retire with a large corpus. The goal is to make that corpus last as long as you need it.

The Festive Sale Trap: Are You Really Saving Money or Just Spending More?
Every year around this time the banners go up. Big Billion Days. Great Indian Festival. Biggest sale of the season. The countdown clocks start ticking on your phone screen before you have even finished your morning chai and somewhere in your head a voice says: this is the week to buy.
These sales are expected to open in the same window this year, right before the festive season starts, just like they have for the last several years. For roughly a week the two platforms will throw everything they have at shoppers: flash deals, bank discounts, exchange bonuses and badges that scream up to 80% off. It is, by most accounts, the best week of the year to buy a phone, a television or a washing machine.
That contradiction sits at the heart of every festive sale season in India. The marketers are winning the game, no question. Whether the consumer is actually winning too is a far messier question and the honest answer is: it depends on how much homework you did before you clicked “buy now.”
The ₹1.2 lakh phone that becomes ₹99,999
Here is a scene that repeats itself on every sale day. A flagship phone is listed with an MRP of ₹1,20,000. During the festive sale it shows up at ₹99,999, a saving that looks like ₹20,000 straight into your pocket. The badge says 17% off. The urgency banner says only a few units left. It feels like a steal.
Except the phone was never really selling at ₹1,20,000 in the first place.
So the “discount” you are celebrating is partly real and partly an illusion built on a number that was inflated to begin with.
Brands and platforms know this works because human beings are wired to judge value by comparison rather than by an absolute number.
How the discount is actually decided
The math behind a festive sale price rarely starts with the question “what can we take off for the customer.” It usually starts somewhere else entirely.
Brands and platforms sit down months in advance and work backward from a margin target. A phone manufacturer wants to move old inventory before a new model launches. A platform wants to hit a gross merchandise value number that looks good in its next investor update. A bank wants more of its credit cards used during the festive quarter. All three sit at the same table and negotiate who absorbs how much of the “discount.”
Often the brand raises the base price a few weeks before the sale begins, then cuts it back down during the sale so the final number looks dramatic against the newly inflated one. Platforms add their own promotional coupons on top, funded partly by the seller and partly by the platform’s own marketing budget. Banks chip in an instant discount of 5 to 10 percent, capped at a fixed amount, in exchange for pushing their card to millions of shoppers who might not have applied for it otherwise. No cost EMI schemes are dressed up as free financing when in reality the “interest” is usually built quietly into the product price rather than charged separately.
Stack all of that together and the final number on your screen is not really a price. It is the output of a negotiation between four or five parties, none of whom were in the room to represent you.
How consumers end up fooled
None of this works without a few psychological nudges and Indian shoppers have gotten fairly familiar with most of them by now, even if they still fall for them.
Fake urgency is the most common one: “Only 2 left” or a countdown timer that resets the moment the sale extends by another day. Price history erasure is another, since most product pages show only the current price and the so called original one, never the actual trend over the past three months. Bundling dresses up value by throwing in an accessory or a subscription that inflates the perceived worth of the deal without meaningfully cutting the price of the product itself. Confirm shaming shows up in smaller ways too, in the guilt inducing pop up that appears when you try to close a cart or skip an add on, worded to make declining feel like a mistake.
India’s consumer regulator has actually put a name and a rulebook to a lot of this. The Central Consumer Protection Authority notified the Guidelines for Prevention and Regulation of Dark Patterns back in 2023, listing thirteen specific practices as unfair trade practices, including false urgency, drip pricing, basket sneaking and bait and switch. In 2025 the CCPA issued fresh advisories asking platforms to self audit and fined companies including an ed-tech major and a global security software firm for using manipulative design. More than two dozen major platforms have since submitted self declarations claiming to be free of these patterns, though the regulator has made clear that monitoring will continue regardless of what companies declare on paper.
The existence of a rulebook does not mean every seller follows it closely. It just means a shopper today has a name for the trick when they see it, which is more than they had a few years ago.
How to shop the sale without letting the sale shop you
None of this means festive sales are worthless. Genuine price drops do happen, especially on last generation electronics, home appliances nearing a model changeover, and fashion inventory that retailers simply need to clear before the next season. The trick is separating the real cuts from the theatre around them.
A few habits go a long way. Track the actual price of a product over the past two to three months rather than trusting the strikethrough MRP on the page, since several browser extensions and price tracking sites now do this for Indian marketplaces. Compare the same product across platforms and the brand’s own website before deciding, because the “biggest” sale badge does not always mean the lowest price on the internet that day. Read the fine print on no cost EMI offers and work out the flat price if you paid upfront, since the difference tells you how much interest is actually hiding inside the “zero cost.” And resist the countdown clock.

Copper Hits a Record High. Should You Care?
Prices are up 16% in 2026. Here’s what’s driving the rally – and what it could mean for your investments.
Copper prices have hit an all-time high of $14,533 per tonne on the London Metal Exchange (LME), taking the metal’s gains to around 16% so far in 2026.
At first glance, this may sound like just another commodities-market story.
But copper is different.
It is used in everything from power grids and electric vehicles to electronics, renewable energy projects and AI data centres. So when copper prices rise sharply, the impact can eventually show up in company profits, product prices and even investment portfolios.
So, why is copper suddenly so expensive?
The biggest reason is a simple one: supply is getting tighter while demand remains strong.
Copper inventories have been falling in key markets. Shanghai Futures Exchange inventories, for instance, have dropped to around 63,000 tonnes – roughly 85% below their mid-March levels. LME inventories are also showing signs of tightness.
At the same time, copper is becoming increasingly important to the global economy.
Think about the growth of:
- – Electric vehicles
- – Renewable energy
- – Power transmission and grids
- – Electronics
- – AI data centre
All of these require significant amounts of copper.
There is also a short-term supply issue. Global copper-mine production fell 1.1% in the first half of 2026, while concentrate production declined 2.6%. Production problems in major copper-producing countries such as Chile, Indonesia and the Democratic Republic of Congo have added to supply concerns.
And expectations around possible US tariffs on refined copper have further distorted global supply flows, pulling more metal towards the US and tightening availability elsewhere.
But what does this have to do with your money?
More than you might think.
1. Copper prices can affect the things you buy
Copper is an important input for electrical products, cables, appliances, construction and other industrial goods.
When the cost of a key raw material rises, companies have two choices: absorb the higher cost or pass some of it on to consumers.
That means a prolonged copper rally could eventually put pressure on the prices of some products and services.
Some manufacturers are already looking at alternatives such as aluminium to manage higher copper costs.
For your household budget, this is one reason commodity prices matter even if you never trade commodities.
2. Your investments could already have copper exposure
You don’t necessarily need to buy copper directly to have exposure to the copper cycle.
Companies involved in copper mining, processing, cables and other industrial businesses can benefit when copper prices rise – although their stock prices don’t automatically move in line with copper.
For example, Hindustan Copper gained nearly 5% in early trading on September 8 after copper hit a fresh record.
But this is where investors need to be careful.
A copper rally does not automatically mean every copper-related stock is a good investment.
A company’s profits also depend on production costs, debt, management, competition and valuations.
So buying a stock simply because “copper is going up” can be a very different bet from investing in the copper theme itself.
3. Should you buy copper now?
This is probably the most important question.
Not just because it has hit a record high.
Copper may have a strong long-term story, but commodities can be extremely volatile. After a sharp rally, prices can also see profit-taking and corrections. Analysts quoted by Moneycontrol expect near-term volatility even though the longer-term demand story remains constructive.
And there is another problem for Indian retail investors: directly investing in copper isn’t as straightforward as buying gold or silver.
India currently doesn’t have a domestic copper ETF or mutual fund that gives simple direct copper exposure. Direct participation is primarily through commodity derivatives such as MCX copper futures, but these involve leverage, margin requirements and significant risk. A standard MCX copper futures lot is 2.5 tonnes, making it unsuitable for many small investors.
So if you’re looking at copper today and thinking, “Prices are going up – should I jump in?”, the answer isn’t necessarily yes.
The bigger personal-finance lesson
Copper’s rally is a good reminder of something investors often forget:
A good investment story doesn’t automatically make it a good investment for you.
Copper has a compelling long-term narrative – electrification, AI, EVs and expanding power infrastructure could keep demand strong.
But that doesn’t mean you need to chase the rally.
For most investors, the first priority should still be a diversified portfolio aligned with their goals, time horizon and risk appetite.
If you already have diversified equity exposure, you may already have some indirect exposure to the industrial and infrastructure themes driving copper demand.
And if you’re considering a commodity allocation, understand what you’re buying, how volatile it can be and how much of your portfolio you’re willing to put at risk before making a decision.
Because the real question isn’t:
“Will copper go higher?”
It’s: “Does copper belong in my portfolio – and if yes, how much?”
That’s the question worth asking when any asset hits an all-time high.
