Random Walk Theory

History of  Random Walk Theory The term ‘Random Walk’ was popularized by the 1973 book, “A Random Walk Down Wall Street”, by Burton Malkiel, Professor of Economics and Finance at Princeton University. Burton G. Malkiel, did a test where his students were given a hypothetical stock that was initially worth fifty dollars. The closing stock price for each day was determined by a coin flip. If the result was heads the price would close a half point higher, and subsequently if the result was tails, it would close a half point lower. Each time there was a fifty-fifty chance of the price closing higher or lower than the previous day. There were cycles or trends determined from the tests. Malkiel then took the results in a chart and graph form to a chartist (a person who “seeks to predict future movements by seeking to interpret past patterns on the assumption Continue reading

The Link Between Innovation and Strategy

Innovation is usually defined as the successful commercial exploitation of new ideas or simply as the successful implementation of new ideas. This encompasses ideas that are ‘new to the world’, ‘new to an industry’ or merely ‘new to a particular firm’.

Indeed, so important is the successful implementation of new ideas that Drucker famously reflected that: ‘Business has only two basic functions Continue reading
