Portfolio Optimizer

This project implements the simple Markowitz portfolio optimization model. It is the foundation of modern portfolio theory.

The assumptions of the model are:

1. Risk of a portfolio is based on the variability of returns from said portfolio.
2. An investor is risk averse.
3. An investor prefers to increase consumption.
4. The investor's utility function is concave and increasing, due to their risk aversion and consumption preference.
5. Analysis is based on single period model of investment.
6. An investor either maximizes their portfolio return for a given level of risk or minimizes their risk for a given return.
7. An investor is rational in nature.

The algorithm needs a timestamped dataset of stock prices, which can be obtained from Yahoo Finance, Google Finance or other sources. A sample table structure is as follows:

The algorithm will provide the efficient frontier visually:

and the optimal portfolio weights numerically:
