I have to analyze the SEC for a company this semester. I chose the SEC 10-k for Game Stop Corp for Fiscal year 2016. We learned about vertical analysis this past week and we are supposed to use the information from our chosen company to complete the following. Wondering if someone could help me understand this process better and since each accounting statement has variable terms what I am generally looking for. Thanks for the help. Hopefully through more examples and Home Work I can get this accounting thing down.

SEC 10-K Project: Statement of Stockholders' Equity

Using vertical analysis (show your calculations), present values for this year and last year:

1. gross profit margin
2. net profit margin (use the last "net income" line on the statement)
3. Comment on changes: Are sales increasingly profitable? How is gross profit and net income changing, as a dollar value?
