Reports came out Friday of a crash involving one of Apple’s self-driving cars. The vehicle was apparently rear-ended while merging onto the expressway near Apple’s Cupertino headquarters.

The Apple/Lexus vehicle was traveling about 1 mph when it was hit by a Nissan Leaf traveling at about 15 mph. There were no injuries.

Finally, S&P and MSCI have announced that they will be shuffling the stocks that make up the global industry classification system (GICS), reconstituting the sectors.

Apple stays in the tech sector, but Amazon is being reassigned to the consumer discretionary sector, and both Facebook and Alphabet are being added to a new communications services sector that is replacing the old telecom sector. Apple’s influence in the tech sector is very likely to increase as a result of these changes.
