Fixed shares vs. floating shares
Shares outstanding that are held long term and rarely traded in the market — such as those held by major shareholders, executives, treasury stock, and cross-held strategic shareholdings — are referred to as "fixed shares," while the remainder, which circulates more freely in the market, is called "floating shares." A higher floating share ratio is generally associated with greater market liquidity, or ease of trading.
What to keep in mind
Stocks with a low floating share ratio are sometimes noted for having a tendency to move sharply even on relatively small trading volumes. The Tokyo Stock Exchange's listing maintenance criteria for its market segments (Prime, Standard, and Growth) include floating share ratio requirements, making it one of the factors relevant to market-segment classification.
