The Kuwait Stock Exchange (KSE) on Wednesday suspended trading in the shares of 50 firms, about a quarter of those listed on the bourse, for not reporting their financial results on time.
A statement posted on the KSE website said the companies failed to announce financial results for the July-September period within the stipulated 45 days.
Twenty-two of the firms had already been suspended for not declaring results for previous periods.
Most of the firms suspended are investment companies that have so far failed to recover from the fallout of the global financial crisis of 2008.
The third-largest Arab bourse in market value after Saudi Arabia and Qatar, the KSE has around 210 Kuwaiti and Gulf companies listed and a capitalisation of $100 billion.
Among the firms suspended are troubled Investment Dar, a leading Islamic investment company that has been reeling under the impact of the financial crisis.
