Investment Securities are a category of securities that are purchased with the intention of holding them for investment. Unlike other securities, investment securities are not bought with the intention of quickly reselling them. Instead, they are meant to be held onto and used as a way to generate income or grow assets over time.There are many different types of investment securities, including stocks, bonds, and mutual funds. Each has its own set of risks and rewards that can appeal to different investors.For example, stocks tend to be more volatile than bonds but offer the potential for greater returns; meanwhile, bonds tend to be less risky but may provide lower returns overall. Ultimately, it is up to each individual investor to decide which type of security best suits their needs and goals.Investment securities can offer a great way to diversify one's portfolio and earn passive income over time. However, it is important to remember that all investments come with some degree of risk; therefore, it is crucial to do your research before investing in any security."
