Question

A work colleague was bragging that the actively managed mutual fund he selected among your employer’s 401(k) electives outperformed the S&P 500 over the past 3 years. The colleague (who did not take FINC 561) claims that it’s a great fund, that the manager is a genius and is urging you to invest in that fund as well.

However, you believe that markets are efficient. Do you take your colleague’s advice? Explain your rationale by applying concepts of market efficiency learned so far in the course. Include whether the mutual fund’s performance violates or disproves efficient markets and why or why not?

Answer 1

No i am not take Colleague's Advise.

Market Efficiency :

• Market efficiency refers to the degree to which market prices reflect all available, relevant information. If markets are efficient, then all information is already incorporated into prices, and so there is no way to "beat" the market because there are no undervalued or overvalued securities available.
• There are three degrees of market efficiency. The weak form of market efficiency is that past price movements are not useful for predicting future prices. If all available, relevant information is incorporated into current prices, then any information relevant information that can be gleaned from past prices is already incorporated into current prices. Therefore future price changes can only be the result of new information becoming available.
• Based on this form of the hypothesis, such investing strategies such as momentum or any technical-analysis based rules used for trading or investing decisions should not be expected to persistently achieve above normal market returns. Within this form of the hypothesis there remains the possibility that excess returns might be possible using fundamental analysis. This point of view has been widely taught in academic finance studies for decades, though this point of view is no long held so dogmatically.
• The semi-strong form of market efficiency assumes that stocks adjust quickly to absorb new public information so that an investor cannot benefit over and above the market by trading on that new information. This implies that neither technical analysis nor fundamental analysis would be reliable strategies to achieve superior returns, because any information gained through fundamental analysis will already be available and thus already incorporated into current prices. Only private information unavailable to the market at large will be useful to gain an advantage in trading, and only to those who possess the information before the rest of the market does.
• The strong form of market efficiency says that market prices reflect all information both public and private, building on and incorporating the weak form and the semi-strong form. Given the assumption that stock prices reflect all information (public as well as private), no investor, including a corporate insider, would be able to profit above the average investor even if he were privy to new insider information.

Mutual fund’s performance violates or disproves efficient markets and why or why not?

• The question of whether markets are efficient, and if not, where the inefficiencies lie, is central to investment valuation. If markets are, in fact, efficient, the market price provides the best estimate of value, and the process of valuation becomes one of justifying the market price. If markets are not efficient, the market price may deviate from the true value, and the process of valuation is directed towards obtaining a reasonable estimate of this value. Those who do valuation well, then, will then be able to make 'higher' returns than other investors, because of their capacity to spot under and over valued firms. To make these higher returns, though, markets have to correct their mistakes – i.e. become efficient – over time. Whether these corrections occur over six months or five years can have a profound impact in which valuation approach an investor chooses to use and the time horizon that is needed for it to succeed.
• So based on the Market Efficiency their is Violation if Mutual fund's Performance.
