Portfolio Management - Essay Example This obviously shows that this theory is not entirely correct. The theory further interpreted shows that investors who thoroughly analyse the market are wasting their time. This theory was coined from the belief that, since the market was often efficient, then it was always efficient. This is however, not always true (Hagstrom, R. 2001, 158). The efficient market theory by Eugene Fama bases its argument on a number of assumptions. First is that all investors rationally seek to maximize the value of their investments. This means that the information that investors receive on their stock investments can make them react randomly either by overreacting or vice versa. This goes to say that they cannot be predicted or exploited thereof for the purpose of making a profit.

It is obviously a much more complex undertaking than it seems. Timing and information is any investor’s best asset when it comes to this. As everyone is scrambling to buy stocks and bonds from large companies, one can take this opportunity to target the smaller upgraded companies that others seem to overlook.

One of the most overstated but true investment rules that few seem to follow is to diversify. Diversifying one’s investment por tfolio is a sure way to reduce the risk of losses all the while increasing the chances of good returns on investment. Diversifying however does not just mean investing randomly in different companies.
