All stocks are somewhat correlated. When the market overall goes up or down, it drags all the stocks along somewhat. When investors get more confident in the market overall, they also get more confident in each individual stock. See this example of Microsoft and Ford[1]. When the companies are so similar like Lyft and Uber, you'll of course get even more correlation. But Lyft and Uber differ beyond just May. Since June 1, Uber is up 16%, and Lyft is down 24%.
