What is the example of efficient market hypothesis?
While academics point to a large body of evidence in support of EMH, an equal amount of dissension also exists. For example, investors such as Warren Buffett have consistently beaten the market over long periods, which by definition is impossible according to the EMH.

For example, if you put 100 Joules of energy into a machine, and got 50 Joules back out (and the other 50 Joules was wasted by the machine), you would have 50% efficiency. So, if you put in 50 Joules and got 45 Joules back, you would have: % Efficiency = (45 J) / (50 J) * 100% =?
What is the best definition of efficiency?
The term efficiency can be defined as the ability to achieve an end goal with little to no waste, effort, or energy. Being efficient means you can achieve your results by putting the resources you have in the best way possible. Put simply, something is efficient if nothing is wasted and all processes are optimized.
