FYI: Oil's crash over the last few months has dominated the headlines, and over the last couple of weeks, its impact has been felt on stocks as well. If you're wondering, below is a chart showing the correlation between the daily movements in oil and stocks. The chart shows the rolling one-year correlation between the daily percentage changes of oil and the S&P 500. A correlation of 1 would mean the two have moved hand in hand with each other over the past year, while a correlation of -1 would mean the two have mirrored each other over the past year.
