Research Analyst at Infovesta Kapital Advisori, Arjun Ajnawi, stated that the IHSG’s strengthening was triggered by improved investor risk sentiment, following a peace agreement between the United States and Iran. He explained that all global stock exchanges experienced significant gains as investors responded positively to the news. ‘Risk sentiment improved because there is positive news from the global geopolitical landscape,’ Arjun said. He added that the announcement of a ceasefire and the opening of the Strait of Hormuz provided a positive global sentiment, causing all Asian markets to rally. Arjun noted that investors began allocating their funds to risk assets such as the stock market, including in emerging markets like Indonesia. ‘The reason the market rose is because of this (US-Iran deal), so clearly investors are entering stocks because stocks are up today,’ he said.
