The term "blue chip" originates from poker, where blue chips hold the highest value. Applied to stocks, it refers to shares of companies that are industry leaders, financially robust, and have typically demonstrated consistent earnings and dividend payments over many years.
On the CSE, blue-chip stocks are generally the companies that make up the S&P SL 20 index — the 20 largest and most liquid firms listed on the exchange. These include major banks, diversified conglomerates, large plantation companies, and leading industrial groups.
Blue chips are often favoured by conservative investors seeking stability and reliable income. They tend to be less volatile than smaller companies because their size and market position provide some insulation from economic shocks. That said, they are not risk-free — large companies can still decline significantly in difficult economic conditions.
In the Sri Lankan context, several blue-chip companies also have strong institutional and foreign fund ownership, making them the most internationally recognised representatives of the local equity market.
