Basic usage example:

What is Beta?

Beta is a measure the systematic risk. In most simple terms, the Beta of a stock is the percentage change in the stock's return, given a 1% change in the market.

Function Arguments

First Argument: Stock Symbol (Required)

The stock symbol for which you want to calculate beta (e.g., "MSFT", "AAPL", "TSLA").

Second Argument: Comparison Symbol (Optional)

By default, it takes SPY as the comparison symbol. But, we can select any ticker symbol other than SPY, like a stock (AAPL) or any other ETF. This is the benchmark against which beta is calculated.

Third Argument: Time Frame (Optional)

By default, it calculates the Beta on a daily basis. But the user can use any time frame: "daily", "weekly", or "monthly". This determines how frequently data points are sampled.

Examples

- Calculates beta against SPY on a daily basis.

- Calculates beta against AAPL on a daily basis.

- Calculates beta against AAPL on a monthly basis.
