You throw out Graham,but have you read the Intelligent Investor?? Are you familiar with the Graham formula? Do you understand the concept of value investing,discount to Intrinsic and the value investing approach??
This. Please actually read Graham. Then talk value investing.
I look at everything I buy from a value perspective. Graham has some key tests for what is a value. You need to consider a variety of factors besides p/e such as debt.
Value investing is specifically not just chasing price around. It requires actually looking at a company's financial statements.
I really wish there was more discussion of actual value investing here.
