Payback Time

Phil is back. This time, he talks more about how to calculate the 'margin-of-saftey' price of a stock. By treating the public business as a private business, you can calculate how long it will take to make your money back. It's apparently an useful way to figure out if you're purchasing at a discount. He also talks about watching stock prices to detect price floors/ceilings and attributes large buyers/sellers as the ones responsible. It inspired me to make a new spreadsheet!
