The AGEM Index increased by 3.6 percent month-on-month in May 2026, rising 54.38 points to 1,578.22, supported by stock price gains among most of its listed gaming supplier companies.
Compared with the same period last year, however, the index declined by 9.4 percent, or 162.96 points.
Seven of the nine companies included in the AGEM Index reported stock price increases during the month. These movements resulted in six positive contributions and three negative contributions to the index.
Aristocrat Leisure Limited was the largest positive contributor in May. The company’s stock price rose by 6.0 percent, adding 37.65 points to the index.
Agilysys also made a notable positive contribution, with its stock price increasing by 35.1 percent during the month. The gain contributed 26.28 points to the AGEM Index.
Konami Corp. was the largest negative contributor, despite a 0.2 percent increase in its stock price. The impact of a weaker Japanese yen exchange rate resulted in a 6.56-point decline for the index.
The monthly increase came as all three major U.S. stock indices also advanced. The NASDAQ rose by 8.4 percent, while the S&P 500 gained 5.1 percent. The Dow Jones Industrial Average increased by 2.8 percent from the prior month.
