Oil and equity indexes

The correlations indicate a positive relationship between oil and these US equity indexes. However, individual factors dominated oil and these equity indexes’ returns. The rise in US crude oil inventory levels dragged oil prices. Hope for progress in the trade war talks supports equity indexes like the S&P 500 (SPY).

Energy sector relative to the broader market

In the trailing week, the Energy Select Sector SPDR ETF (XLE) rose 2%. XLE had the second-lowest rise among the SPDR ETFs that divide the broad market into subsectors. The recovery in the broader market might have contributed to XLE’s upside. The Communication Services Select Sector SPDR ETF (XLC) fell 2.1% and underperformed the SPDR ETFs. The Materials Select Sector SPDR ETF (XLB) had the largest rise of 6.9%. Most of the SPDR ETFs ended in the green.
