What is form of investment for security and non security investment?

Security investments refer to financial instruments that represent an ownership position or creditor relationship, such as stocks, bonds, and mutual funds. Non-security investments include tangible assets like real estate, commodities, or collectibles, which do not represent a claim on future cash flows. Both types of investments serve different purposes in a portfolio, with security investments generally focusing on liquidity and marketability, while non-security investments often emphasize diversification and potential appreciation in value.
