Not understanding concept of the challenge


in the holding portfolio challenge, it seems like all they are asking us to do is create a new class that only holds an array of all the stocks we created, and be able to add up their values for a total value. is this correct? it just seems like a lot more work for so little info inside a class when i could do the exact same thing in main.m in just a few lines without a whole new class. correct?

edited: and the symbol property too, but i originally did something very very similar to that when we first created the stocks project so i could more easily distinguish which stock was which in the output.
