Building a (very simple) portfolio tracker with pandas

All of these graphs were created in Colab. I’ve actually never found a commercial product that does everything I want, so I figured I’d build one up in a series of blog posts. We’ll see how many I get through! ๐Ÿงต๐Ÿ‘‡ First, we’ll get SPY’s stock history with pandas_datareader.
