Investment groups are organizations where individuals pool their money to invest in various assets, such as stocks, real estate, or businesses. This collective approach allows members to share risks and benefits, making it easier to access larger investment opportunities than they could individually. Members of investment groups often collaborate to make decisions, share insights, and research potential investments. These groups can vary in size and structure, ranging from informal gatherings of friends to formal organizations with specific investment strategies, such as hedge funds or private equity firms.
