Correlation is a measure of relationship between variables that is measured on a -1 to 1 scale. The closer the correlation value is to -1 or 1 the stronger the relationship, the closer to 0, the weaker the relationship. It measures how change in one variable is associated with change in another variable. Correlation in Python Correlation values range between -1 and 1. There are two key components of a correlation value: magnitude – The larger the magnitude (closer to 1 or -1), the stronger the correlation Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try: To do this with scipy try: from scipy.stats.stats import pearsonr a = [1,4,6] b = [1,2,3] print pearsonr(a,b)

Here is a quick tutorial in python to compute Correlation Matrix between multiple stock instruments using python packages like NSEpy & Pandas. Generally Correlation Coefficient is a statistical measure that reflects the correlation between two stocks/financial instruments. Instead, let's look into the correlation of all of these companies. Building a correlation table in Pandas is actually unbelievably simple: df_corr = df.corr() print(df_corr.head()) That's seriously it. The .corr() automatically will look at the entire DataFrame, and determine the correlation of every column to every column. I've seen paid websites do exactly this as a service. Let’s briefly discuss this. Open is the price of the stock at the beginning of the trading day (it need not be the closing price of the previous trading day), high is the highest price of the stock on that trading day, low the lowest price of the stock on that trading day, and close the price of the stock at closing time. # The below will pull back stock prices from the start date until end date specified. start_sp = datetime.datetime(2013, 1, 1) end_sp = datetime.datetime(2018, 3, 9) # This variable is used for YTD performance. end_of_last_year = datetime.datetime(2017, 12, 29) # These are separate if for some reason want different date range than SP. stocks_start = datetime.datetime(2013, 1, 1) stocks_end = datetime.datetime(2018, 3, 9)
