Why you should not trade unit trust.

The following conclusion was reached according to the Dalbar Study, which originated in 1995 in the United States, to determine the profitability of trading for the small investor of mutual funds (unit trusts).

An investor who bought an S&P 500 index fund would have earned 11.9% annually for the twenty years from 1986 through 2005. The average equity investor, however, earned a 3.9% annual return. Investors who hold their investments have the potential for greater success than those who try to “time” the market.

The Buy & Holders will love the results as it "proves" that buying and holding is better than trying to switch to so-called "hot" funds. However, one should not just buy and hold mindlessly.
There are a few reasons for the underperformance of the average equity investor:
1) Investors poured money into recent "hot" funds after hearing and seeing huge gains.
2) The fund managers are then unable to successfully invest the large cash inflows.
3) Investors selling away the funds after a few quarters of tepid performance.

To improve one's chances of coming out on top, my recommendation is to buy a low cost passive fund. Not to mention returns, a high cost fund will immediately burn a hole in your pocket.

What is synergy?

Mergers and acquisitions are arguably the most popular and influential form of discretionary business investment. Synergy is a word often found in the press release of the reasons given by the acquirer when they bought over another company. Like a major R&D project or plant expansion, acquisitions are a capital budgeting decision. Stripped to the essentials, an acquisition is a purchase of assets and technologies. But usually, the acquirer often pay a premium over the stand alone market value of these assets and technologies. They pay for something called synergy.

The common definition of synergy is 2 + 2 = 5. However, the accurate definition should be increases in competitiveness and resulting cashflow beyond what the 2 companies are expected to accomplish independently. It can simply be modeled as:
NPV = synergy - premium

From the above formula, one can understand why the share price of the acquirer usually drops after the announcement. If a high premium was paid, the net present value of the assets and technologies gained will be negative if the expected synergy did not occur. According to a McKinsey study, more than 60% of the the acquisition programs were failures because the acquisition strategies did not earn a sufficient return on the funds invested. Companies that do not understand this fundamental fact risk falling into the synergy trap.


Quote of the day
The market, like the Lord, helps those who help themselves. But, unlike the Lord, the market does not forgive those who know not what they do. A too high purchase price for the stock of an excellent company can undo the effects of a subsequent decade of favourable business developments.

What drives the stock market?(2)

Behavioral-finance theory holds that markets might fail to reflect economic fundamentals under three conditions. When all three apply, the theory predicts that pricing biases in financial markets can be both significant and persistent.

Irrational behavior.
Investors behave irrationally when they don't correctly process all the available information while forming their expectations of a company's future performance. Studies have shown that investors often put too much weightage and focus on recent events and results, regardless of the level of significance. This is an error that leads them to overprice companies with strong recent performance. Others are excessively conservative and underprice stocks of companies that have released positive news. Similarly, stock prices of companies tend to get oversold after 1 or 2 quarters of weak financial earnings.

Systematic patterns of behavior.
Even if individual investors decided to buy or sell without consulting economic fundamentals, the impact on share prices would still be limited. Only when their irrational behavior is also systematic (that is, when large groups of investors share particular patterns of behavior) should persistent price deviations occur. Hence behavioral-finance theory argues that patterns of overconfidence, overreaction, and overrepresentation are common to many investors and that such groups can be large enough to prevent a company's share price from reflecting underlying economic fundamentals—at least for some stocks, some of the time.

Limits to arbitrage in financial markets.
When investors assume that a company's recent strong performance alone is an indication of future performance, they may start bidding for shares and drive up the price. Some investors might expect a company that surprises the market in one quarter to go on exceeding expectations. As long as enough other investors notice this myopic overpricing and respond by taking short positions, the share price will fall in line with its underlying indicators.
However, this sort of arbitrage doesn't always occur. In practice, the costs, complexity, and risks involved in setting up a short position can be too high for individual investors, especially in singapore market, where the terms and conditions do not favour the short-sellers.

What drives the stock market?(1)


As stock markets around the world are into the bull mode, investors have been asking the themselves the above question. During the past few decades, the academic theory brought forward was that financial markets accurately reflect a stock's underlying value. But lately, the view that investors can fundamentally change a market's course through irrational decisions has been moving into the mainstream.


With the exuberance of the high-tech stock bubble and the crash of the late 1990s still fresh in investors' memories, adherents of the behaviorist school are finding it easier than ever to spread the belief that markets can be something less than efficient in immediately distilling new information and that investors, driven by emotion and greed, can indeed lead markets awry. Some behaviorists would even assert that stock markets lead lives of their own, detached from economic growth and business profitability. A number of finance scholars and practitioners have argued that stock markets are not efficient—that is, that they don't necessarily reflect economic fundamentals. According to this point of view, significant and lasting deviations from the intrinsic value of a company's share price occur in market valuations.


Most agreed that behavioral finance offers some valuable insights—chief among them the idea that markets are not always right, since rational investors can't always correct for mispricing by irrational ones. In fact, significant deviations from intrinsic value are rare, and markets usually revert rapidly to share prices commensurate with economic fundamentals. Therefore, investors and managers should continue to use the tried-and-true analysis of a company's discounted cash flow to make their valuation decisions.
