Tutorial time! As stated yesterday, Book Value Per Share is the total value of a company’s assets minus the company’s liabilities, divided by the number of shares outstanding. Let's take a look at where to find and how to derive this for Redfin ($RDFN), a company I was discussing two days ago.

First off, you can find any company's financial documents at sec.gov

The most recent 10Q will work for us:

The balance sheet already gives us the stockholder's equity, so we don't need to do the calculation of assets - liabilities. That number is $355,260. We have to multiply this number by 1000 because the balance sheet states it in thousands.

It also shows us the total shares outstanding is 99,394,432.

355,260 x 1000 / 99,394,432 = $3.57

So Redfin's book value per share is $3.57.

Hopefully this was a helpful way to get a little more acquainted with sec.gov and looking at financial statements.
