Define bins

A histogram is a bar chart that can be used to display the empirical distribution of historical stock returns. To build a histogram, the first step is to divide the range of historical returns into equal intervals, called bins.

In this exercise, your task is to divide the series of ABC historical returns into 30 bins.

To do so, use the following procedure:

Compute minimum and maximum return.
Compute the range by taking the difference between maximum and minimum return.
Divide such a difference by the number of bins minus one, and you’ll get the width of each bin.
Starting from the minimum, add iteratively the width and you’ll gradually come up with regular intervals of values.

In F3:G3, use the functions MIN() and MAX() to find the minimum and maximum return.
In H3, compute the range based on the values found above.
In J3, compute the width of each interval.
In G7:H36, identify all the bins.

In the first chapter, you’ll be introduced to the problem: you have a time series of monthly (historical) prices for the hypothetical stock ABC from which you have to extract some meaningful information. You’ll be given some definitions (what is a stock? what are dividends?), and at the end of the chapter, you’ll be able to graphically represent the evolution of a stock price over a specific period.

Exercise 1: Introduction and first metrics Exercise 2: What is a stock?Exercise 3: Count prices and dividends Exercise 4: Find minimum and maximum prices Exercise 5: Find minimum and maximum dividends Exercise 6: Identifying dates with unusual prices Exercise 7: Find price at a given date Exercise 8: Find dates with minimum and maximum prices Exercise 9: Visualizing the price evolution Exercise 10: Plot a line chart of historical prices Exercise 11: Customize the chart Exercise 12: Highlight minimum and maximum prices

In this chapter, the core of the analysis will switch from historical prices to historical returns. You’ll learn (and compute) the main performance indicators of past returns, both in terms of reward and risk. Finally, you’ll be introduced to risk-adjusted performance measures: indicators that take into account both reward and risk.

Exercise 1: From prices to returns Exercise 2: What are dollar and percentage returns?Exercise 3: Compute historical returns Exercise 4: Count positive and negative returns Exercise 5: Reward metrics Exercise 6: Compute the average return Exercise 7: Compute the effective rate of return using PRODUCT() and COUNT()Exercise 8: Compute the effective rate of return using ARRAYFORMULA()Exercise 9: Risk metrics Exercise 10: Compute the volatility Exercise 11: Compute the volatility with STDEV()Exercise 12: Compute the historical value-at-risk Exercise 13: Risk-adjusted metrics Exercise 14: Compute the Sharpe ratio Exercise 15: Compute the semideviation Exercise 16: Compute the Sortino ratio

In this chapter, you'll look at the full distribution of historical returns. First, you’ll learn how to build a histogram to describe the distribution of historical returns. Second, you’ll be introduced to the Gaussian distribution, a commonly used model for stock returns. You'll visually inspect if the Gaussian model is reasonable for the ABC stock returns. Finally, you'll understand potential flaws with the Gaussian model.

In this final chapter, you’ll benchmark ABC stock against a market index and verify whether ABC outperformed the benchmark or not. The comparison process will be done through several steps/metrics. First, you’ll analyze the cumulative wealth. Next, you’ll extend the comparison using different indicators such as Sharpe Ratio and Drawdown. Finally, you’ll examine the linear relation between ABC stock and the benchmark through the correlation coefficient. At the end of the chapter, you’ll be introduced to more powerful and advanced spreadsheet features that introduce interactivity in your analysis.
