The name itself reveals the essence of the term. An adjustable rate is a rate that varies over time.  

When a trader, for example, trades, with leverage in the financial markets the interest rate on the borrowed fund may fluctuate depending on market movements. This rate change is beyond the control of Banks and savings institutions. 

Suppose you borrowed $500 at a 5% rate of interest loaned to you by someone. Depending on policy adjustments; this interest rate could rise to 15% or drop to 4% which is something beyond the borrower’s influence.

To better understand what after trading hours are, it is best to first explain “trading hours.” Trading hours refer to the time when the buying and selling of stocks happens over major exchanges such as the New York Stock Exchange or NASDAQ. 

They are usually open from 9:30 a.m. to 4:00 p.m. EST. When major news and events take place, some traders might continue to trade after the market closes, until around 8:00 p.m. EST. 

If a company issues a new stock after trading hours, traders will react quickly to major news or events and can invest in it immediately. However, they need to be cautious, as after-hours trading entails significant price volatility due to lower trading volumes. 

Aggregate demand refers to the total demand for goods and services produced within an economy over a period of time.

It includes consumer demand for durable and nondurable goods, investment spending by companies in capital goods, and government expenditure on public services.

 Additionally, it accounts for the difference between exports and imports of goods and services of the country, which is net exports.

In order to fulfill the demand for goods and services created in the economy during a certain period the economy must assess the total supply available.  

The concept of aggregate supply refers to the amount of goods and services produced within an economy from local sources that are accessible to fulfill aggregate demand. 

Let us consider an illustration to understand how this connects to trading. If a nation is able to fulfill its demand with a robust domestic supply; it indicates a healthy economy and generally supports a stronger currency.
