Burton Malkiel

Who is Burton Malkiel?

Burton Gordon Malkiel is an American economist and writer, most famous for his classic finance book A Random Walk Down Wall Street. He is a leading proponent of the efficient market hypothesis, which contends that prices of publicly traded assets reflect all publicly available information, although he has also pointed out that some markets are evidently inefficient, exhibiting signs of non-random walk.

Malkiel in general supports buying and holding index funds as the most effective portfolio-management strategy, but does think it is viable to actively manage "around the edges" of such a portfolio, as financial markets are not totally efficient.
