My apologizes for posing such a basic question, but I cannot seem to find the answer anywhere.
I am comparing the share price of British Airways and Ryanair for a research paper. When I look at the price of each company over 5yrs on individual line chart, I get completely different prices when I compare the two on the same chart.
For example, looking at the chart of the individual companies over 5yrs, the price is never negative and they reach as high 215. However, on the same chart, the price drops to nearly -50 and only as high as 125.
How is the chart comparing the two companies? What am I missing?
