Difficult terms explained: IPO (Initial Public Offering): This is the process where a private company offers its shares to the public for the first time, allowing it to raise capital from investors and become a publicly traded entity. Subscription: In an IPO, subscription refers to the extent to which the shares offered to the public have been applied for. A subscription of 'X times' means that for every share offered, 'X' applications were received. Grey Market Premium (GMP): This is an unofficial indicator of demand for an IPO. It represents the premium at which IPO shares are trading in the grey market (an unregulated market) before their official listing on stock exchanges. A positive GMP suggests strong demand and expectations of listing gains. Anchor Investors: These are institutional investors (like mutual funds, insurance companies, or foreign portfolio investors) who commit to buying a large portion of an IPO before it opens to the general public. They provide stability and credibility to the issue. Qualified Institutional Buyers (QIBs): These are large institutional investors who are registered with capital market regulators and are permitted to invest in public issues. Examples include mutual funds, venture capital funds, and foreign institutional investors. Non-Institutional Investors (NIIs): This category includes high-net-worth individuals, companies, trusts, and other entities that invest more than the retail investor limit (typically above Rs 2 lakh) but are not QIBs. Retail Individual Investors (RIIs): These are individual investors who apply for shares up to a certain limit (usually Rs 2 lakh) in an IPO. Original Equipment Manufacturers (OEMs): These are companies that produce finished goods (like vehicles) and integrate various components supplied by other manufacturers into their final product. Tenneco Clean Air India supplies components to them.
