What Investors Should Learn from Past GMP Trends?
As stated in the introduction of this article, the grey market is speculative and should not be trusted much also it is neither regulated nor managed by government institutions. However, based on the report above, here are a few well-informed, opinionated lessons for investors concerning GMP trends. It includes the very bad, a few good, and some ugly.
- GMP is a sentiment-driven and not data-driven
The grey market is unofficial and is not within the jurisdiction of the SEBI. This grey market is the only aspect of the stock market where sentiments are allowed to judge prices. Consider the grey market, as the period between the listing price of an IPO and the opening price, where “well-informed” gamblers try to speculate or guess just how much more an IPO would set its opening listing price above the issue price. It is rarely data or research-driven approach. - Low GMPs do the least damage
For a long-term investment strategy, purchasing the shares of a company with a low GMP might seem a better strategy. And the reason isn’t quite complicated. The lower the GMP, the potentially lower the risk of the shares dipping badly after a while. The rationale is such IPOs are not driven by hype, but instead by the slow and steady growth in the demand for the company's shares over time. An exception, of course, would be a company with so many obvious red flags, it couldn't even move the needle of a GMP. Other than that, it is a safer strategy than investing in the fake hype that dictates some GMPs. - Invest what you are willing to lose in high-hype IPOs
The human condition to gamble, FOMO, and the thrill of quick profit can sometimes be strong, and sometimes very hard to defeat in the face of an IPO with a really amazing GMP. So, what should you do if you find yourself in this situation? Invest that which you are willing to lose. Diversify your investment, putting the bulk into more stable, reasonable portfolios. - Cross-check with RHP / DRHP
This might seem like a rookie perspective, but it isn't. You do not want to be one of those investors whose only data is the GMP and who have absolutely no idea about the company they are rooting for. The least any investor can do is cross-check the company's RHP and DRHP. Think about it, why would a GMP be 80 percent of the listing price? Why? What is so special about the company? These are among the questions proper research can provide answers to.
Conclusion
The data-driven report in this article goes on to prove a long-standing bias about GMP. They are best for signals, rather than a tool for investment strategy. A high GMP does not guarantee a high opening listing price nor an assurance that he stock of a company would do well or not.

FAQ: Highest Grey Market Premium (GMP) in Last 5 Years
1. Does a high Grey Market Premium (GMP) guarantee strong listing gains?
Grey Market Premium (GMP) is unofficial and unregulated, and is mainly driven by market sentiment. A high GMP does not always guarantee strong listing gains. For example, the MapmyIndia IPO had a projected GMP of around 102%, but the stock eventually listed at about a 53% premium over its issue price, falling short of market expectations.
2. Why do some IPOs with high GMP fail to meet expectations on listing day?
Grey Market Premium (GMP) does not guarantee anything. It is unofficial and comes from the grey market, which is unregulated and driven largely by sentiment. If grey market sentiment is high for a particular issue, it may reflect in a higher GMP.
However, the listing price is determined by actual market demand on listing day and has no direct linkage with GMP. For example, LatentView Analytics had a projected GMP of around 195% of its issue price, but it eventually listed at about a 160% premium, lower than grey market expectations.
