Tight public float
Public shareholders holding under a quarter of the company — scarcity as a price amplifier.
When public shareholders hold less than 25%, whoever holds the rest — promoters, the government, a foreign parent — is not selling at market prices. The tradable float is a fraction of the listed size, so the same buying moves the price further, in both directions. Listed subsidiaries and recent listings sitting at the minimum public shareholding live on this list. It reads best alongside a demand signal — a volume or delivery scan — because scarcity only amplifies interest that already exists; on its own it is a property of the stock, not an event.
