Plotting multi-period returns
The last time series method you have learned about in the video was .pct_change(). Let's use this function to calculate returns for various calendar day periods, and plot the result to compare the different patterns.
We'll be using Google stock prices from 2014-2016.

Manipulating Time Series Data in Python
Istruzioni dell'esercizio
We have already imported pandas as pd, and matplotlib.pyplot as plt. We have also loaded 'GOOG' stock prices for the years 2014-2016, set the frequency to calendar daily, and assigned the result to google.
- Create the columns
'daily_return','monthly_return', and'annual_return'that contain thepct_change()of'Close'for 1, 30 and 360 calendar days, respectively, and multiply each by 100. - Plot the result using
subplots=True.
