what is the marketable security and give examples please?

Answer 1

A "security" is a financial product that has something underneath it. A "marketable security" is something where there is an active listed or prominent over-the-counter market, where the security can be bought and sold.

For example, marketable securities include:

Equities (i.e. publicly listed stocks)
Bonds (e.g. certificates of deposits, corporate bonds, government bonds, agency bonds)
Derivatives (e.g. calls, puts, swaps, futures)
Commodity futures (e.g. Brent crude oil futures, winter wheat #9 futures, orange juice futures)
Securitized portfolios (e.g. bundles of mortgages, bundles of receivables, bundles of high yield bonds, bundles of car loans)

What is NOT included:

Illiquid investments (e.g. art collections, wine collections, private equity)
Property
