The securities market is a pivotal component of the global financial system, serving as the marketplace where securities such as stocks, bonds, and derivatives are bought and sold. It facilitates capital formation, enables price discovery, and provides liquidity to investors.
Primary Market
The primary market is where new securities are issued and sold for the first time. Companies raise capital by issuing new shares or bonds.
Secondary Market
The secondary market is where existing securities are traded among investors. The stock exchanges like NYSE and NASDAQ are prime examples of secondary markets.
Over-the-Counter (OTC) Market
In the OTC market, securities are traded directly between parties without a centralized exchange. This market is less regulated compared to traditional exchanges.
Bond Market
A section of the securities market where debt instruments are traded. It includes government and corporate bonds.
Importance of the Securities Market
The securities market plays a crucial role in the economy by:
- Providing Liquidity: Enables investors to buy and sell securities easily.
- Facilitating Capital Formation: Helps companies raise capital for expansion.
- Enabling Price Discovery: Market forces of supply and demand determine the price of securities.

Efficient Market Hypothesis (EMH)
$$ P_t = E(P_{t+1} \mid I_t) $$
where \( P_t \) is the price of the security at time \( t \) and \( I_t \) is the information available at time \( t \).
Black-Scholes Model
$$ C = S_0N(d_1) - X e^{-rt}N(d_2) $$
where:
- \( C \) is the call option price.
- \( S_0 \) is the current stock price.
- \( X \) is the strike price.
- \( r \) is the risk-free interest rate.
- \( N \) is the cumulative distribution function of the standard normal distribution.
- \( d_1 \) and \( d_2 \) are calculated using the given formula.
Real-world Examples
