Imagine you are drafting an initiation report on a legacy Public Sector Undertaking (PSU) that has just been earmarked for a strategic divestment by the government. Your colleagues are fixated on the potential improvement in operating margins under private management, but as a seasoned analyst, you must look at the structural change in market liquidity.
When the government offloads a large stake to a strategic partner or offers shares to the public through an Offer for Sale (OFS), the free-float of the company changes overnight, directly impacting its trading volumes and institutional interest.
Privatization typically triggers a transition from a government-controlled entity with limited retail engagement to a market-driven corporation. This shift often enhances transparency and corporate governance, which in turn attracts foreign institutional investors (FIIs) and domestic mutual funds who previously avoided the stock due to regulatory overhang or political interference. As more shares become available for public trading, the stock’s bid-ask spread often narrows, significantly reducing the transaction costs for institutional investors entering or exiting large positions.
Consider the case of a major government-held oil refinery or logistics firm. Before divestment, the high promoter holding usually restricts the available supply of shares, leading to low trading liquidity that discourages large-cap index funds from holding the stock. Once a significant percentage is divested, the increased free-float allows the stock to qualify for inclusion in major benchmarks like the Nifty 50 or S&P BSE Sensex. This inclusion creates a permanent demand floor through passive investment vehicles, which serves as a major valuation tailwind for the firm.
From a valuation perspective, your model must account for this ’liquidity premium.’ As an analyst, you should adjust your terminal value or discount rate downwards to reflect the lower liquidity risk associated with a widely-held private company. Failing to account for the influx of institutional liquidity post-privatization can lead to an undervaluation of the stock, as you might ignore the positive price impact that passive fund inflows create upon a successful transition to private ownership.
