Stocks Data Analysis and Visualization in Python
-Created a funtion to perform portfolio analysis by calculating return, risk and Sharpe ratio
-The main problem was the huge manual effort required and the visualization of the results
-Reduced analysis time by 20%
-Wrangling data of different stocks and combining them into a single dataframee.
-Missing values.
-Plotting QQ plot for stock modelling.
-Graph of volatility clustering conveyed that stock volatility doent follow a normal distribution but actually a T-distribution
-High volatility regions lie close to each other and low volatility region lie next to each other
-We have to avoid stocks whose returns have negative skew because they will end up losing a lot of times
-Excessive kurtosis means more reward but that comes with a price of more risk.
-Pandas, Numpy, Matplotlib.py
-Kaggle
-Recent data obtained from Quandl
-Took data of all stocks and combined them in a single dataframe containing only the strike price and close price
-Fill up missing values by forward fill and backward fill
-Removing Duplicates.
-Histogram of returns data in matplotlib.py and plotly express to understand its distribution
-Volatility vs time plot to observe the change in volatily over time.
-Price vs time to observe the stock returns over time
