The Philippine Stock Exchange (PSE) began 93 years ago, on August 8, 1927. Five Manila-based businessmen to increase trading activity that would stimulate the business atmosphere put their plan into action, and founded the Manila Stock Exchange, the first Stock Exchange in the Philippines and one of the oldest in the Far East. On May 27, 1963, the Makati Stock Exchange (MSE) was organized by five other businessmen. So, for about 30 years the Philippines had two stock exchanges, the Manila Stock Exchange (MSE) and the Makati Stock Exchange (MKSE). Although the two exchanges remained separate, they basically were trading the same listed issues. The idea to unite the two exchanges and have it managed by a professional group emerged and was attained when the Philippine Stock Exchange, Inc. was incorporated. PSE is currently the only organized exchange in the Philippines licensed for trading stocks and warrants.
