The real risk free rate can be calculated as the subtraction between the Yield to Maturity of a Treasury Bond and the inflation.īut of all bonds with different durations which one should I choose?

The model tell us that the expected return of the asset i (E(R i)) is given by the sum of the risk free rate (Rf) plus the beta of the asset multiplied by the market expected return (E(R m)) subtracted by the risk free rate. # We give the function the empty dataframe, the name of the assets, the initial date and the end date: def datosYahoo(dataframe,asset_list,start,finish): for i in asset_list: dataframe = data.DataReader(i,data_source='yahoo',start= start, end=finish) return dataframe df = datosYahoo(df_prices,assets,initial_date,today) df Then we use the following Python function that will automatically give us the “Adj Close” column of the Yahoo Finance data from the date we chose. With this information we are ready to obtain the data from Yahoo Finance, but first we must create and empty dataset where the data is going to be stored. initial_date = "" today = datetime.today().strftime('%Y-%m-%d') For this example, we are going to obtain the data from 5 years ago until now. Now that we have the list of the assets, we must define the date from which we are going to obtain the data. Also, the ticker name of our benchmark, the NASDAQ, is ^IXIC. In the case of Apple, for example, it appears listed on the NASDAQ as AAPL. To obtain the data, we set up a list with the names of the tickers of the stocks we are going to use. That’s why we are going to use this index as benchmark or market portfolio. The NASDAQ generally is the place where the tech companies are listed. These companies are listed in the NASDAQ (^IXIC) : the second largest index in the US.Those companies are: Apple (AAPL), Microsoft (MSFT), Amazon (AMZN), Alphabet (GOOGL), Facebook (FB), Tesla (TSLA) and Visa (V). For this case, I will choose the biggest US tech companies in market capitalization.First, we need to choose the assets we want to work with:

You may need to install PuLp and pandas-datereader library and to do that you can run the following commands: pip install pulp pip install pandas-datareader import pandas as pd import numpy as np from datetime import datetime import matplotlib.pyplot as plt import statistics import seaborn as sns from pandas_datareader import data from pulp import * As you can see in the image of the efficient frontier, the blue dot represents the maximum Sharpe Ratio that you can achieve with all the possible Portfolios.įirst thing first, we need to import the libraries that we will use. The ratio is the average excess of return above the risk free rate adjusted by the volatility of the asset. The Sharpe Ratio indicate us the risk of an investment measured by it’s risk. One of the assumptions we need to make when we work with the returns is that they can be modelled as a normal distribution, where the risk or volatility is the standard deviation of the data. Mathematically the dispersion accounts for the standard deviation of the returns of the assets. The volatility measures the dispersion of the returns from the mean. Any portfolio that is below the red line for the s ame amount of risk, can improve the expected return with a different combination of the portfolio weights.
