Philip A. Fischer famously said:

Investors have been so oversold on diversification that fear of having too many eggs in one basket has caused them to put far too little into companies they thoroughly know and far too much in others which they know nothing about.

and

The successful investor is usually an individual who is inherently interested in business problems.

He dropped out of Stanford to get his ‘education’ at the Anglo London Bank as an analyst. Post another short stint at a stock firm, he started his own Fischer and company where he worked till the ripe old age of 91. His client list was carefully picked and he was a very private man. His investments though were hardly traditional. Fischer chose to invest in companies that were known for their innovation. He chose his stocks carefully and held them in long positions. Motorola and Texas instruments were some of his picks.

His investment philosophy was not unlike an art form. He felt that a business must be studied in depth before its stock is picked or not pick it at all.
