When we regularly track corporate announcements on the stock exchanges, we notice a large number of insider trading disclosures and SAST-related notifications almost every day. This naturally raises an important question for retail investors.
Should we give serious importance to these notifications, or are they just routine compliance filings with no real meaning?
The truth lies somewhere in between. Most of these disclosures are routine and can be ignored. However, a small number of them can provide early signals, if we know how to filter and interpret them correctly.
Why Promoter and Insider Activity Matters
In any company, the people who know the business best are the promoters and insiders. They have first-hand knowledge about what is happening inside the company and the industry. They will invest their own money only when they believe the future prospects are improving.
That is why promoter buying, insider buying, and certain SAST transactions can be important, especially in companies that may be heading toward a turnaround.
However, this does not mean that every promoter or insider transaction should be taken seriously.
Most Notifications Are Just Noise
Let us understand this with an example. Assume a company has a market capitalization of ₹10,000 crore. If a promoter buys shares worth ₹5 lakh or ₹10 lakh occasionally, this information is not very meaningful.
The amount is too small compared to the size of the company. Such buying does not necessarily indicate strong conviction or future growth expectations.
Many retail investors make the mistake of reacting to these small transactions, which usually leads nowhere.
Focus on Substantial Acquisitions
What really matters is whether the acquisition is substantial in relation to the company’s size.
For example, if a company with a market capitalization of ₹5,000 crore or ₹10,000 crore sees promoters buying shares worth ₹1 crore, ₹2 crore, or more, and this buying happens repeatedly, then such notifications deserve attention.
Similarly, in a smaller company with a market capitalization of ₹100 crore or ₹200 crore, even promoter buying of ₹50 lakh or ₹1 crore can be considered substantial.
On the other hand, the same ₹50 lakh purchase in a very large company has little significance.
Importance of Continuous Buying
One-time buying can happen for many reasons. What truly matters is continuous buying over a period of time.
When promoters repeatedly buy shares, it usually indicates growing confidence in the business, improvement in the sector, or positive internal developments.
This is the kind of activity retail investors should track closely.
Real-Life Observation from the Market
In recent times, there has been an example where continuous promoter buying was observed over a short period. Multiple promoters were purchasing a decent number of shares consistently, even though such activity was not visible earlier.
When such patterns appear, investors should not invest blindly. Instead, this should be treated as a starting point for deeper research.
The next step is to understand what is happening in the company and the sector. If additional bullish signals are also visible, only then does it make sense to consider investing.
Sector Context Is Very Important
Sometimes, promoter buying becomes more meaningful when it happens during a difficult phase for an industry.
If an entire sector has been struggling for years and promoters still continue to buy shares, it may indicate that conditions are slowly improving or that a recovery is expected in the future.
This makes tracking such notifications even more important.
Tracking Bulk and Block Deals
Along with promoter and insider transactions, it is also important to track bulk and block deals.
Serious investors invest large amounts of money only when they see long-term growth potential. While some participants in bulk deals may be short-term traders or arbitrage players, many are long-term investors.
If we track these deals consistently for a few months, it becomes easier to identify who is genuinely accumulating and who is just trading.
How Retail Investors Should Use This Information
Promoter buying, insider activity, and bulk deals should not be treated as direct buy signals.
They should be used as filters and starting points for research. Investors should then study the company’s business, financials, sector trends, and overall market conditions before making any decision.
When multiple positive factors align, the probability of a good investment outcome improves.
Final Thoughts
Most retail investors fail because they react to every disclosure without understanding its significance.
The key is not the number of shares bought, but the size of the investment relative to the company and the consistency of buying.
Used correctly, promoter and insider data can help investors stay ahead of the crowd. Used blindly, it becomes just another source of noise.
