Investing in irrational markets

Investing in irrational markets
Hock's Viewpoint - By Choong Khuat Hock

The financial crisis reflects the fallacy of the ‘efficient market hypothesis’

IT is amazing that economic theories still consider that markets are governed by the “efficient market hypothesis” (EMH), which assumes rational investors, an orderly market and that all available information are known.

The global financial crisis reflects the fallacy of EMH and textbooks should be revised to reflect this.

In reality, markets reflect the nature of its creators and participants – a collection of human beings who would like to think they are rational but are often enough irrational and emotional.

Quantitative models often fail to model the irrationality of human behaviour during extreme times.

Blind reliance on such models was also the reason why Long-Term Capital Management (LTCM, which had Nobel Prize-winning economists) failed as the restructuring of defaulting bonds in Russia in 1998 caused volatilities beyond what was predicted by quant models.

The extremely high leverage utilised by LTCM hastened its demise. Alan Greenspan had to engineer a rescue as the failure of LTCM threatened to damage the markets and market participants.

One way of valuing securities is to use the discounted cash flow model, which is to discount the expected future cash flows to obtain the present value.

Behavioural finance has many theories to explain why humans are often irrational but the reality is that irrationality is hardwired into our brains.

However, in many cases, future cash flows are difficult to predict and the discount rate used would fluctuate depending on the prevailing interest rates and the perception of risk which may vary from person to person.

This method is more useful in valuing businesses or securities with predictable cash flows like utility stocks where cash flows are stable and funding costs have been determined. Another popular valuation method is to compare securities with its peers.

Such comparisons are ingrained in the nature of human beings as we can only determine the value or utility of something by comparing it to another. Shall I buy the latest Samsung or Sony LCD TV? How does a BlackBerry compare with an iPhone?

Similarly, if the price-earnings ratio (PER) of a stock is 10 times and the sector PER is 20 times, it may be considered cheap if specific company factors are attractive.

Using sector PER as valuation anchor is fraught with danger as the sector valuation may be unreasonable.

Such comparisons may not reflect the value of potential cash flows from an investment. At the height of the dot.com bubble, valuations were based on price to sales with no consideration placed on cash flow.

The prevailing belief then was that there was a sucker willing to pay a higher price to sales for the business.

The same happened during the debt fueled property bubble in the US when rental yields from property could not cover mortgage payments.

Banks were willing to provide 100% financing to those who could not afford houses based on the assumption that property prices could only go up and mortgage loans could be repackaged into much sought after high yielding subprime securities.

Behavioural finance has many theories to explain why humans are often irrational but the reality is that irrationality is hardwired into our brains.

The brain can be divided into two parts – the hypothalamus, or primal brain, (a few hundred million years old) which directs our instinctive behaviour and the neo-cortex, or new brain, (a few million years old) which facilitates logical deductions, learning from experience, language and complex social interactions.

In times of panic, the hypothalamus takes over and markets tend to overshoot on the downside due to panic selling.

Since these moves are often irrational, the movements tend to be many standard deviations more than what is predicted by a normal distribution curve, creating black swan events.

Faced with an avalanche of incomplete information, humans use heuristics, a simplification process to arrive at a decision based on their past experiences and prejudices.

In arriving at a rule of thumb valuation, anchoring is employed by imputing a fair value to the initial entry level even if the entry level is high.

Therefore, in a rising property market, anchoring may result in the belief that the price appreciation will continue.

A bubble can thus form as the herd is blinded by cognitive dissonance whereby investors pay credence only to views and opinions that reinforce their beliefs. However when the discrepancy between fantasy and reality becomes too large, the bubble bursts.

Investment is hence as much an art as it is science. In the final analysis, it is the cash flow that counts.

The science would be in accurately determining the cash flow but the art lies in determining how much investors are willing to pay for the cash flows.

Identifying periods of over pessimism and optimism would help in determining entry and exit points.

In the end, the advantage lies in accurately predicting beforehand where the herd is heading. Understanding the animal in you and others could indeed be a profitableproposition.

Alibaba says Yahoo 'reckless' on Google stance

January 16, 2010 Alibaba says Yahoo 'reckless' on Google stance (AP)

(AP) -- China's e-commerce giant Alibaba turned on major shareholder Yahoo Inc. on Saturday, calling the American company's support of Google in its standoff with China "reckless."

Google has promised to stop censoring its search results in China, threatening to pull out of the country altogether if it can't operate an unfiltered search engine. Yahoo has said it was "aligned" with Google's position, though it's not clear what that means.

"Alibaba Group has communicated to Yahoo! that Yahoo's statement that it is 'aligned' with the position Google took last week was reckless given the lack of facts in evidence," Alibaba spokesman John Spelich said Saturday. "Alibaba doesn't share this view."

Yahoo closed its own offices in China several years ago when it sold much of its business there to the Alibaba Group. Yahoo retains a 39 percent stake in Alibaba that represents one of Yahoo's most valuable assets.

Yahoo spokeswoman Nina Blackwell has declined to say whether the company would consider selling its holdings.

Google hopes it can persuade the Chinese government to agree to changes that would enable its China-based Google.cn site to show uncensored search results.

A Google spokeswoman, Jessica Powell, said by e-mail Saturday that Google has not closed its offices in China and that "it's business as usual."

Google's threat to end its China operations has alarmed an Internet-connected public that is the world's largest at 384 million people.

Beijing requires Internet traffic to pass through government-controlled gateways that block access to material deemed subversive or pornographic. Google's China-based site excludes from its results any foreign Web sites to which access is blocked.

Baidu Bulls Hit The Options Hard

Baidu Bulls Hit The Options Hard
Andrew Wilkinson, Interactive Brokers, 01.16.10, 11:05 AM EST
Buying call options on Baidu has created life-changing wealth in the past year for some investors. The fervor for shares is still strong.

Baidu ( BIDU - news - people ): Bullish investors continue to trade January contract calls and puts on the Chinese language Internet search provider today even with expiration close at hand. News reports today indicate some at Credit Suisse ( CS - news - people ) anticipate Google ( GOOG - news - people ) may exit the Chinese market as soon as February. Disbanding Google operations in China could allow Baidu to swoop in and procure one-third of the U.S. company's market share there. Shares of BIDU traded 0.75% higher to $467.86 around noon Friday.

Baidu bulls bought roughly 3,200 calls at the January $470 strike for an average premium of $2.08 apiece. These contracts will expire out-of-the-money and worthless unless shares rally above the $470 level. Investors long the calls break even if the stock rallies up to $472.08 before the contracts expire. Additional buying interest appeared as high as the January $480 strike, where 2,000 calls were picked up for an average premium of 48 cents per contract. Perhaps traders buying these out-of-the-money contracts hope to enjoy short-swing profits by selling the lots by the end of the day for more than the average premium paid.

Optimism is apparent on the put side as well. Investors sold 3,400 puts at the January $460 strike to take in premium of $2.35 each. Another 1,900 puts were shed at the in-the-money January $470 strike for an average premium of $5.85 per contract. In-the-money put sellers are happy to have shares of the underlying stock put to them at an effective price of $464.15 each if BIDU's share price trades below the $470 strike price through expiration.

Jim Oberweis told his subscribers to buy Baidu at $79 and told them to buy more at $110 in early 2009. Click here for Oberweis' current advice and access to the complete model portfolio in the Oberweis Report.

Alcoa ( AA - news - people ): Medium-term optimism on the largest producer of aluminum took root in the July contract today despite the 1.5% decline in the value of the underlying shares to $15.58. It looks like one investor purchased 20,000 calls on the stock at the July $20 strike for a premium of 51 cents per contract. The large bullish stance positions the trader to amass profits if Alcoa's shares surge more than 31.5% over the current price to surpass the break-even point at $20.51 by expiration in six months. Option implied volatility is down 7.17% on the day to stand at 38.05%.

Sprint Nextel ( S - news - people ): Shares of the wireless communications company were trading 1.9% higher Friday to $3.76. Options activity in the August contract indicates that one investor is positioning for a significant rally in shares of the underlying stock in the next seven months to expiration.

It looks like the trader purchased 15,000 calls at the August $7 strike for a premium of 12 cents per contract. Profits on the calls accrue if Sprint's share price jumps 87% from the current level to surpass the break-even point at $7.12 by August expiration. On trades like this it's less likely that the investor has an eye on the strike price as a target price, but uses a larger amount of relatively inexpensive call options to play out a directional play on the underlying stock. In this case the delta on the $7 call option indicates a 15% chance that Sprint's shares will land in-the-money at expiration, while gamma tells us that a $1 rally to $4.80 (an increase of 26%) would shorten those odds to 28%. We note that shares have not traded above $7 since Sept. 19, 2008.

Pfizer ( PFE - news - people ): It looks like one investor rolled a large chunk of now in-the-money call options in the January contract on the global pharmaceutical company forward to a higher strike price in the February contract Friday. Shares slipped slightly lower during the session, falling 0.25% to $19.31. The January $19 strike had approximately 62,000 calls sell for an average premium of 43 cents per contract, spread against the apparent purchase of about the same number of calls at the higher February $20 strike for a premium of 28 cents each. The calendar roll results in a net credit to the investor of about 15 cents per contract. It is unclear how much the trader initially paid for the January contract calls, but looking at the trade in isolation, this individual pockets 15 cents per contract on the transaction. Elsewhere, traders attempted to lock in recent share price gains on the stock by buying 7,700 in-the-money puts at the February $20 strike for a premium of $1.06 apiece. The put contracts provide protection to traders in case Pfizer's shares slip beneath the break-even point at $18.94 by expiration next month.

CurrencyShares Euro Trust ( FXE - news - people ): With the euro under pressure Friday as Greek bond yields rise--indicative of rising Eurozone tensions--it appears one investor sold February call options at the $1.50 strike to reduce the outlay for the same strike put options. By doing so the investor bearish on the euro reduced the cost of downside exposure for the euro by 2.2%. Elsewhere another investor appeared to buy a substantial amount of 5,000 put options expiring in June at the $1.10 strike. If such a decline in the euro was to play out, since it's currently trading at $1.438, would be indicative of a huge slide of confidence in the Eurozone.
