 analysis to help them in making decisions. They may use several information resources, some of which are strictly technical. Using the pivot points calculated from a previous day's trading, they attempt to predict the buy and sell points of the current day's trading session. These points give a cue to traders as to where prices will head for the day, prompting each trader where to enter his trade, and where to exit. An added tool for the stock picker is the use of "stock screens". Stock screens allow the user to input specific parameters, based on technical and/or fundamental conditions, that he or she deems desirable. Primary benefits associated with stock screens is its ability to return a small group of stocks for further analysis, among tens of thousands, that fit the requirements requested. There is criticism on the validity of using these technical indicators in analysis, and many professional stock traders do not use them.

 in 1970, suggests that at any given time, prices fully reflect all available information on a particular stock and/or market. Thus, according to the EMH, no investor has an advantage in predicting a return on a stock price because no one has access to information not already available to everyone else. In efficient markets, prices become not predictable but random, so no investment pattern can be discerned. A planned approach to investment, therefore, cannot be successful. This "random walk" of prices, commonly spoken about in the EMH school of thought, results in the failure of any investment strategy that aims to beat the market consistently. In fact, the EMH suggests that given the transaction costs involved in portfolio management, it would be more profitable for an investor to put his or her money into an index fund.

At the academic level, the very concept of market timing (the act of attempting to predict the future direction of the market, typically through the use of technical indicators or economic data) is called into question by those who believe in the efficient market theory. This theory is based on the premise that, at any given time, prices fully reflect all available information on a particular stock and/or market. Thus, no investor has an advantage in predicting a return on a stock price because no one has access to information not already available to everyone else.

Beating the market, fraud and scams

Outside of academia, the controversy surrounding market timing is primarily focused on day trading conducted by individual investors and the mutual fund trading scandals perpetrated by institutional investors in 2003. Media coverage of these issues has been so prevalent that many investors now dismiss market timing as a credible investment strategy. Unexposed insider trading

Day trading sits at the extreme end of the investing spectrum from conventional buy-and-hold wisdom. It is the ultimate market-timing strategy. While all the attention that day trading attracts seems to suggest that the theory is sound, critics argue that, if that were so, at least one famous money manager would have mastered the system and claimed the title of "the Warren Buffet of day trading". The long list of successful investors that have become legends in their own time does not include a single individual that built his or her reputation by day trading.

, who made his fortune trading in time horizons ranging from 30 minutes to 30 days, claimed to take a long-term perspective on his investment decisions. From an economic perspective, many professional money managers and financial advisors shy away from day trading, arguing that the reward simply does not justify the risk. Despite the controversy, market timing is neither illegal nor unethical. Attempting to make a profit is the reason investors invest, and buy low and sell high is the general goal of most investors (although short-selling and arbitrage take a different approach, the success or failure of these strategies still depends on timing).

The problems with mutual fund
Mutual fund
A mutual fund is a professionally managed type of collective investment scheme that pools money from many investors to buy stocks, bonds, short-term money market instruments, and/or other securities.- Overview :...

 trading that cast market timing in a negative light occurred because the prospectuses written by the mutual fund companies strictly forbid short-term trading. Despite this prohibition, special clients were allowed to do it anyway. So, the problem was not with the trading strategy but rather with the unethical and unfair implementation of that strategy, which permitted some investors to engage in it while excluding others. All of the world's greatest investors rely, to some extent, on market timing for their success. Whether they base their buy/sell decisions on fundamental analysis of the markets, technical analysis of individual companies, personal intuition, or all of the above, the ultimate reason for their success involves making the right trades at the right time. In most cases, those decisions involve extended periods of time and are based on buy-and-hold investment strategies. Value investing

 is a clear example, as the strategy is based on buying stocks that trade for less than their intrinsic values and selling them when their value is recognized in the marketplace. Most value investors are known for their patience, as undervalued stocks often remain undervalued for significant periods of time.

Some investors choose a blend of technical, fundamental and environmental factors to influence where and when they invest. These strategists reject the 'chance' theory of investing, and attribute their higher level of returns to both insight and discipline.

 strategies. One reason for this high failure rate is that most new traders start out with too little capital, and the expectation of being able to pay their bills with their trading profits. Another big reason for this high failure rate is that most new traders start without a coherent game plan or strategy to trade. Other major reasons are the unpredictability of the markets, especially in the short-term, the large number of corporate and financial scams and frauds among listed companies, and out-of-control erroneous advertisement and biased aggressive advertising campaigns related with trading, brokerage, stock picking strategies, and so on. Every year, a lot of money is wasted in non-peer-reviewed (and largely unregulated) publications and courses attended by credulous people that get persuaded and take the bill, hoping getting rich by trading on the markets. This allow wide-spread promotion of inaccurate and unproven trading methods for stocks, bonds, commodities, or Forex, while generating sizable revenues for unscrupulous authors, advisers and self-titled trading gurus.
