One-Sided Market

A one-sided market is a market condition where there are predominantly only buyers (no sellers willing to sell at any reasonable price) or predominantly only sellers (no buyers willing to buy at any reasonable price) — making it impossible to execute transactions at fair market prices. In equity markets, a one-sided market typically occurs when a stock hits its upper circuit limit (only buyers, no sellers) or lower circuit limit (only sellers, no buyers) — a regulatory mechanism used by NSE and BSE to manage extreme price volatility by halting trading beyond a specified percentage move. During a one-sided market at the upper circuit, existing holders cannot sell and new buyers cannot immediately acquire shares — creating significant liquidity risk for investors caught on the wrong side of a position. Small and mid-cap Indian stocks — particularly those with low free float, high promoter holding, or subject to sharp news-driven moves — are most prone to one-sided market conditions. Investors should always consider circuit limit risk and liquidity when investing in stocks with small market capitalisations.
