Hello Guilherme,
As an example, when plotting the companies on a graph (question 2a) , you might have Ford’s data from 2008 onwards, while the equally weighted portfolio of Ford and GM may only start in 2010, as that is when the data for GM becomes available (GM went bankrupt in 2009).
Thanks,
Sofia Tomás
