society Maturity 13-18 Next article →

Eugene Fama is a famous economist. He was born in Boston in 1939. His family came from Italy. He studied at Tufts University. Later, he went to the University of Chicago. He has taught there for many years.

Fama is known as the father of modern finance. He studied how stock prices move. He found that short-term price changes are hard to predict. This idea is called the efficient-market hypothesis. It says that prices reflect the information people have. He described three ways this happens. These are weak, semi-strong, and strong forms of efficiency.

Fama also worked with Kenneth French. They made a three-factor model. This model helps explain why stock returns change. It looks at market size and value. In 2015, they added two more parts. This became a five-factor model. It also looks at how much profit a firm makes.

In 2013, Fama won the Nobel Prize in Economics. This is a very big honor. He is one of the most influential economists ever. His work helps us understand how markets work every day.
