Mutual funds offer several advantages to investors

Affordable:
Almost everyone can buy mutual funds. Mutual Funds generally provide a opportunity to invest with less funds as compared to other avenues in the capital market. Even the ancillary fee which one has to pay in the form of brokerages, custodian etc is lower than other options and is directly linked to the performance of the scheme.

Professional Management:
For an average investor, it may be quite difficult to decide what to buy, when to buy, how much to buy and when to sell. Mutual Funds have a skilled professionals who have years of experience to manages your money. The fund manager takes these decisions after doing adequate research on the economy, industries and companies, before buying stocks or bonds. They use intensive research techniques to analyze each investment option for the potential of returns.

Diversification:
Investments are less risky as it is spread across a wide cross-section of industries and sectors. Diversification reduces the risk because all stocks generally don’t move in the same direction at the same time. A mutual fund is able to diversify more easily than an average investor across several companies.

Liquidity:
You can afford to withdraw your money from a mutual fund on immediate basis when compared with other forms of savings like the public provident fund or National Savings Scheme. You can withdraw or redeem money at the Net Asset Value related prices in the open-end schemes. In closed-end schemes, the units can be transacted at the prevailing market price on a stock exchange.

Tax Benefits:
Mutual funds have historically been more efficient from the tax point of view. A debt fund pays a dividend distribution tax of 12.5 per cent before distributing dividend to an individual investor or an HUF, whereas it is 20 per cent for all other entities. There is no dividend tax on dividends from an equity fund for individual investor.

Potential of returns:
Mutual funds generally offer better than any other option over a given period of time. Though they are affected by the interest rate risk in general, the returns generated are more.

Well regulated:
The Mutual Fund industry is very well regulated. All investments have to be accounted for. SEBI acts as a true watchdog in this case and can impose penalties on the AMCs at fault. The regulations are also designed to protect the investors’ interests are also implemented effectively.

Transparency:
As they are under a regulatory framework, they have to disclose their holdings, investment pattern and all the information that can be considered as material, before all investors to ensure transparency which is unlike any other investment option in India where the investor knows nothing as nothing is disclosed.

From experience we know that investors may ‘temporarily’ move financial prices away from their long term aggregate price ‘trends’. (Positive or up trends are referred to as bull markets; negative or down trends are referred to as bear markets.) Over-reactions may occur—so that excessive optimism (euphoria) may drive prices unduly high or excessive pessimism may drive prices unduly low. New theoretical and empirical arguments have since been put forward against the notion that financial markets are ‘generally’ efficient (i.e., in the sense that stock prices in the aggregate tend to follow a Gaussian distribution).

According to the efficient market hypothesis (EMH), only changes in fundamental factors, such as the outlook for margins, profits or dividends, ought to affect share prices beyond the short term, where random ‘noise’ in the system may prevail. (But this largely theoretic academic viewpoint—known as ‘hard’ EMH—also predicts that little or no trading should take place, contrary to fact, since prices are already at or near equilibrium, having priced in all public knowledge.) The ‘hard’ efficient-market hypothesis is sorely tested by such events as the stock market crash in 1987, when the Dow Jones index plummeted 22.6 percent—the largest-ever one-day fall in the United States. This event demonstrated that share prices can fall dramatically even though, to this day, it is impossible to fix a generally agreed upon definite cause: a thorough search failed to detect any ‘reasonable’ development that might have accounted for the crash. (But note that such events are predicted to occur strictly by chance , although very rarely.) It seems also to be the case more generally that many price movements (beyond that which are predicted to occur ‘randomly’) are not occasioned by new information; a study of the fifty largest one-day share price movements in the United States in the post-war period seems to confirm this.

However, a ‘soft’ EMH has emerged which does not require that prices remain at or near equilibrium, but only that market participants not be able to systematically profit from any momentary market ‘inefficiencies’. Moreover, while EMH predicts that all price movement (in the absence of change in fundamental information) is random (i.e., non-trending), many studies have shown a marked tendency for the stock market to trend over time periods of weeks or longer. Various explanations for such large and apparently non-random price movements have been promulgated. For instance, some research has shown that changes in estimated risk, and the use of certain strategies, such as stop-loss limits and Value at Risk limits, theoretically could cause financial markets to overreact. But the best explanation seems to be that the distribution of stock market prices is non-Gaussian (in which case EMH, in any of its current forms, would not be strictly applicable).

Other research has shown that psychological factors may result in exaggerated (statistically anomalous) stock price movements (contrary to EMH which assumes such behaviors ‘cancel out’). Psychological research has demonstrated that people are predisposed to ‘seeing’ patterns, and often will perceive a pattern in what is, in fact, just noise. (Something like seeing familiar shapes in clouds or ink blots.) In the present context this means that a succession of good news items about a company may lead investors to overreact positively (unjustifiably driving the price up). A period of good returns also boosts the investor’s self-confidence, reducing his (psychological) risk threshold.

Another phenomenon—also from psychology—that works against an objective assessment is group thinking. As social animals, it is not easy to stick to an opinion that differs markedly from that of a majority of the group. An example with which one may be familiar is the reluctance to enter a restaurant that is empty; people generally prefer to have their opinion validated by those of others in the group.

In one paper the authors draw an analogy with gambling.[9] In normal times the market behaves like a game of roulette; the probabilities are known and largely independent of the investment decisions of the different players. In times of market stress, however, the game becomes more like poker (herding behavior takes over). The players now must give heavy weight to the psychology of other investors and how they are likely to react psychologically.

The stock market, as any other business, is quite unforgiving of amateurs. Inexperienced investors rarely get the assistance and support they need. In the period running up to the 1987 crash, less than 1 percent of the analyst’s recommendations had been to sell (and even during the 2000 – 2002 bear market, the average did not rise above 5%). In the run up to 2000, the media amplified the general euphoria, with reports of rapidly rising share prices and the notion that large sums of money could be quickly earned in the so-called new economy stock market. (And later amplified the gloom which descended during the 2000 – 2002 bear market, so that by summer of 2002, predictions of a DOW average below 5000 were quite common.)
