Lesson 1: Reading, slicing and plotting stock data
- Overview of the data we'll be working with (from Yahoo!)
- Introduction to our primary library: Pandas
- Reading CSV data into Pandas
- Filtering to specific dates
- Plotting
Reading: "Python for Finance", Chapter 6: Financial time series
Assignment: MC1-Homework-1 Write a function in Python to find the Nth prime number.
Lesson 2: Working with many stocks at once
- Our target data frame structure
- Address reverse order issue
- Reading data for multiple stocks into the structure
- Date slicing
- Symbol slicing
- Plotting
- Normalizing
Lesson 3: The power of Numpy
- What is Numpy and how it relates to Pandas
- Why is Numpy powerful/important?
- Creating Numpy arrays
- Indexing and slicing Numpy arrays
- Important data processing on Numpy arrays
- Example use with pandas too
Reading: "Python for Finance", Chapter 4: Data types and structures
Lesson 4: Statistical analysis of time series
- Gross statistics on dataframes
- Rolling statistics on dataframes
- Plotting a technical indicator (Bollinger Bands)
Lesson 5: Incomplete data
- How incomplete data arises in financial data
- Different approaches to dealing with it
Assignment: MC1-Homework-2 Install and test a Python environment.
Lesson 6: Histograms and scatter plots
- Histogram of daily returns
- Compare SPY with XOM
- Scatter plots
- Correlation is not slope!
- Compare SPY vs XOM, with SPY vs GLD scatter plots
Lesson 7: Sharpe ratio & other portfolio statistics
- Speed up reading data by memoizing
- Average daily return
- Volatility: stddev of daily return (don't count first day)
- Cumulative return
- Relationship between cumulative and daily
- Sharpe Ratio
- How to model a buy and hold portfolio
Assignment: MC1-Project-1 Analyze a portfolio
Lesson 8: Optimizers: Building a parameterized model
- What does an optimizer do?
- Syntax of optimizer use
- Problem statement for an optimizer (inputs, outputs, assumptions)
- How to find X that minimizes f(X) with a minimizer
- How to build a parameterized polynomial model from real data using an optimizer
Lesson 9: Optimizers: How to optimize a portfolio
- Framing the portfolio problem for an optimizer
- Constraints for an optimizer
- Optimizing a portfolio
script
- Frame the portfolio optimization problem for the optimizer
- Add target return
- Plug the parts together in code for 4 assets
- [quiz: Add constraints on holdings]
Assignment: MC1-Project-2 Optimize a portfolio
