Meritz Securities has introduced a new financial platform called 'MOUM,' which combines investment information, a global community, and artificial intelligence (AI) services. This move comes as the importance of investor communities grows in the retail sector, aiming to enhance competitiveness through high accessibility and communication.


During the launch event held at the Fairmont Ambassador Seoul in Yeouido on September 1, Meritz Securities CEO Jang Won-jae stated, "Meritz Securities aims to reject inertia and conventional wisdom in the retail sector, creating a new wave of innovation and shaping the future of investment."


MOUM features a combination of stock trading capabilities from the existing mobile trading system (MTS) with investment information, a global community, and AI services. Users can access key services without a separate login, and community activities are available through social login.


By linking to the online-only comprehensive investment account 'Super365,' users can transition to full membership, allowing them to view stock trading, information on holdings and interests, and AI analysis all on one screen.


Another notable feature is the search function that connects everyday interests to investment ideas. For instance, searching for 'spicy ramen' will yield related food stocks, associated themes, news, and community reactions all at once. This allows users to discover investment targets through everyday keywords, even if they do not know the exact stock names.


The platform also enhances AI-based investment information services. Users can receive additional analysis on specific issues through AI chat, and market information can be accessed in various formats, including 'one-minute short-form videos' and audio-based 'MOUM AI briefings.'


The global investment community is another distinguishing feature. Meritz Securities has integrated its own stock community with the U.S. social investment platform Stocktwits and the global fintech company Webull. This enables domestic investors to check real-time opinions and market reactions from overseas investors, helping them understand global investment trends and ideas.


CEO Jang emphasized, "MOUM is designed with an intuitive and user-friendly interface from the planning stage, providing insights from the global community market without language barriers, with AI services at its core."


Investment convenience for exchange-traded funds (ETFs) has also been improved. Unlike the previous method, where users had to check key indicators and constituent stocks separately, the platform allows for easy comparison of similarities and differences among similar ETFs. Key metrics such as market capitalization, dividend yield, and management fees are aligned on the same criteria, visually distinguishing numerical differences for easier product comparison.


Additionally, 'direct trading' simplifies the process from information exploration to order placement. Given the rapidly changing market conditions, users can place orders directly from the investment decision screen without needing to navigate to a different screen or re-search stocks. Users seeking quick and easy orders can select 'easy mode,' while those desiring more detailed and precise trading can opt for 'pro mode.'


Meritz Securities has built MOUM as a cloud-based open platform, enhancing its scalability and flexibility through collaboration with Amazon Web Services (AWS). In the future, the company plans to integrate Webull's AI technology to develop an 'agent AI financial platform' that understands users' investment goals and context, autonomously performing necessary analyses.


Lee Jang-wook, who oversees the development of MOUM, stated, "As various financial products and trading data continue to connect, investors will find it easier to understand the information they need and make better decisions. We aim to create a new investment ecosystem where people, AI, and various services and data connect and evolve together."
