RSI is a technical metric that measures momentum and helps indicate if an equity is overbought or oversold.
To calculate RSI two equations need to be calculated. In order to calculate the RSI you must first solve for relative strength.
Relative Strength (RS)= Average of "N" day's closes up/ Average of 'N' day's closes down
RSI= 100 - (100/1+RS)
When a stock has an RSI less than 30 it is considered oversold and if it has an RSI greater than 70 it is considered overbought.
When a company is considered oversold it means that the a stock is potentially trading lower in price and could experience an increase in stock price.
When a stock is overbought means that the stock has experienced a consistent upward price trend without experiencing any significant pullback or dip in price.
