Oversubscription Is Not Always a Good Sign

As India’s IPO markets experience unprecedented activity, oversubscription is becoming more and more of a badge of honor for IPO-bound companies. When shares are oversubscribed, it means there was more demand for shares than shares issued.

Investors will often take oversubscription in the book-building process as a sign of a strong company's fundamental performance and a guarantee that the shares will gain on listing day.

Oversubscription Can Create a False Narrative?

The concept of oversubscription has always conveyed excitement and confidence among investors. In recent times, India’s primary market has seen unprecedented levels of participation due to the ease and low-cost nature of IPO applications driven by digital trading applications.

Whereas the retail investors who are typically new to the investing experience see oversubscription as a clear signal for future returns. Potential downside of oversubscription

Retail Participation

A huge misconception about oversubscription is that it represents strong underlying company performance. The reality is that retail investors pay more attention to market excitement, premium bidding in the grey market, or following trends on social media, rather than intensive financial analysis.

Institutional Oversubscription

Pension funds, insurance companies, family offices and sovereign wealth funds, all institutional investors, including Qualified Institutional Buyers (QIBs) are another factor affecting high levels of oversubscription.

QIBs frequently invest significantly in initial public offerings (IPOs) for several reasons:

Short-term allocation opportunities
Strategies for market positioning
Requirements for sectoral exposure
Possibilities for arbitrage

As a result, their participation can inflate oversubscription figures, leading the issuance to appear stronger than it is.

Valuation Concerns

Highly oversubscribed IPOs are often priced at aggressive levels. As demand builds up, companies and investment bankers often push valuations as close as possible to the top of price bands.

Oversubscription May Signal Speculative Interest

GMPs (grey market premiums), social media predictions, and algorithm-driven alert systems tend to engender speculation around IPOs. Many investors apply solely speculatively for the chance of near-term gains and simply add to the oversubscription numbers.

Low Allotment Chances Despite High Participation

Although oversubscription can look impressive in headlines, it poses a disadvantage for retail investors in terms of their allotment chances; they are usually very low.

When an IPO is oversubscribed, particularly in the retail and HNI buckets, the chances of getting at least one lot can be very low.

This means that:

Funds will be blocked for a few days
Missed opportunities in different investments
The illusion of participation without a real shareholding
Not Every Oversubscribed IPO Performs Well Post Listing

History in the market shows that numerous historically oversubscribed IPOs have had disappointing post-listing performances. Several times, the stock price dropped below the issue price within months after the listing date

Some reasons are:

Overvaluation,
Poor quarterly earnings,
Sectoral weakness,
Profit booking post-listing, and
Poor management or governance.
Long-Term Investors Must Look Beyond Subscription Data

Oversubscription should be one of many factors considered, never the deciding one.

Long-term investors must evaluate:

Consistency of revenue growth
Profitability trends
Level of debt
Valuation concern
Competitive positioning
Background of promoters including governance
Use of proceeds from the IPO

Though oversubscription is often considered evidence of an IPO’s strong market demand, it is not a dependable measure of long-term performance or investment quality. More often than not, oversubscription indicates market appreciation, hype or to some degree, speculation and does not guarantee sustainable returns.
