Each item between the slash after the domain name of the website is called an argument. Take, for example, example.com/one/two/three/four/five -- in this case one is the first argument, two is the second argument, ect.. Drupal has a function that separates these arguments named arg() which takes an argument as a number. arg(1) when called while loading this example URL will always return 'one' while arg(5) will always return 'five'. This way context can be passed into all the modules in a consistent way. I just want to make sure you see arguments for what they are.
Here is why. You are creating a two separate pages for items that should be on the same page. Instead of creating pages you might consider blocks in views and place the many blocks on the same page. This way you can, for example, use taxonomy terms to tag content as IBM, Intel or Apple. Create a balance sheet and tag it IBM. Create another tag it Apple. Create an income statement and tag it IBM. Create another and tag it Apple.
Then create a basic page with a brief description of the IBM corporation and a logo using the path alias module to change the name of the URL to example.com/ibm. Then add the two views as blocks to the page. Each view will be called when the user goes to example.com/ibm and arg(1) will be ibm. Then you can use the arguments (in View 3 contextual filters) to use this argument to define the Taxonomy term to filter the information in the database with. In this case IBM. Now you might have 12 reports for IBM for each category going back 4 years. Views will pull them all and you can use a field of title that links to the node to have a link going to each one. Then you can also use the date filter to make sure that the most recent one is on top. Once the View block is created, Views will just load the other view using once again arg(1) to define the taxonomy term to find all the other reports information in the database.
Now there are more advanced ways to trigger which Views get called with modules like Context or Panels which are super high powered tools that focus on just this simple purpose. You might be interested in the videos on Panels at Node One or the Mustard Seed Media video on the Context module.
(edit) To create a similar tabbed look like companies on the WSJ you can use either Quick Tabs for an ajax tabbed effect or creating a Views page and assigning it a Menu Tab for the menu item so that several tabs are found on the same page.
