We have already imported pandas as pd, and matplotlib.pyplot as plt. We have also loaded Google and Apple stock prices in a variable data.

Define a variable investment with the value 1000.
Calculate returns by applying .pct_change() to data.
Add 1 to returns and assign this to returns_plus_one, then apply .cumprod() to returns_plus_one and assign the result to cumulative_return.
Multiply cumulative_return by investment, and plot the result.
