Talking about his successful investment secrets, Warren Buffet shares:
"I just sit in my office and read all day…. I read the annual reports of the companies I care about and their competitors – that's the main source of material."
One of the main documents Buffet reads is the 10-K Report (Form 10-K). According to Buffet, the 10-K report is where businesses showcase their inner strength, beyond glossy PR materials.
