Portfolio up, S&P down

It's always nice to see a long-only portfolio go up when the broader market goes down. Today, the S&P500 lost close to 1%. Historically, days with losses of more than 1% in the S&P500 have occurred less than 10% of the time since 1950. The portfolio is up by ~0.3% today, mainly as a result of a profitable trade by extreme-os.
