Understanding Coefficient of Variation

What is the Coefficient of Variation (CV)?

The Coefficient of Variation (CV) is a statistical measure used to assess risk per unit of return. It’s especially useful for comparing investments with different expected returns and standard deviations.

By calculating the CV, investors can easily compare investments and choose the more efficient one in terms of risk relative to return.

---

Example to Understand the Concept

Let’s examine two investments:

• Investment 1
  Expected Return: 0.40
  Standard Deviation: 0.22

• Investment 2
  Expected Return: 0.23
  Standard Deviation: 0.14

---

How is the Coefficient of Variation Calculated?

To calculate the Coefficient of Variation, divide standard deviation by expected return.

For Investment 1:
Coefficient of Variation=0.220.40=0.55\text{Coefficient of Variation} = \frac{0.22}{0.40} = 0.55Coefficient of Variation=0.400.22​=0.55

For Investment 2:
Coefficient of Variation=0.140.23=0.61\text{Coefficient of Variation} = \frac{0.14}{0.23} = 0.61Coefficient of Variation=0.230.14​=0.61

---

Which Investment Should You Choose?

For a risk-averse investor, the best choice is typically the investment with a lower Coefficient of Variation, as it indicates lower risk for each unit of return.

Here, Investment 1 is the better option because its CV (0.55) is lower than Investment 2’s CV (0.61). This means Investment 1 offers a more efficient balance between risk and return.

---

Why is the Coefficient of Variation Important?

Most investors prefer investments that minimize risk for each unit of expected return. The Coefficient of Variation provides a simple calculation to help investors compare different investments and choose the one that best aligns with their risk preferences.

A Wise Man Should Have Money in His Head, Not in His Heart

“A wise man should have money in his head and not in his heart.”
— Jonathan Swift

This timeless quote highlights an essential principle of financial wisdom—money should be guided by reason, not emotion.

When money sits in the heart, decisions are influenced by fear, greed, attachment, and impulse. This often leads to poor financial choices, unnecessary risks, or emotional stress.

When money stays in the head, it is handled with logic, planning, and purpose. It becomes a tool for stability, growth, and long-term security rather than a source of anxiety or obsession.

True wealth is not just about accumulation, but about clarity, control, and conscious decision-making.

 

“Wall Street People Learn Nothing and Forget Everything”

— Benjamin Graham

This powerful quote captures a timeless truth about financial markets. Despite experiencing repeated cycles of booms, bubbles, crashes, and recoveries, many market participants continue to repeat the same mistakes, driven by greed during rising markets and fear during downturns.

The Timeless Nature of Human Behaviour

The lesson is clear:
Markets change, technology evolves, but human behaviour remains constant. This is a core concept that every investor should understand. Whether it’s the dot-com bubble or the housing crisis of 2008, the underlying emotions of fear and greed drive the same patterns of behaviour.

The Key to Success: Discipline

Successful investors are those who:

1. Study history and learn from past market cycles.

2. Stay disciplined, even in the face of market euphoria or panic.

3. Resist emotional decision-making, even when the crowd moves in the opposite direction.

Why History Matters

Every market cycle provides valuable lessons, and those who fail to study history often find themselves repeating mistakes. By understanding how markets behave over time, investors can avoid the pitfalls of emotional investing and build a more resilient portfolio.

Avoiding Emotional Decision-Making

During market upswings, many investors become overly optimistic, thinking the good times will last forever. Conversely, during downturns, the fear of loss can cause them to panic sell. Both behaviours are driven by emotions, and successful investors know how to manage them effectively.

The Bottom Line

In the end, successful investing is not about predicting the future, but about staying consistent, following a disciplined strategy, and avoiding the emotional traps that many investors fall into. By doing so, you can achieve long-term success, regardless of the market conditions.

“The Market Can Remain Irrational Longer Than You Can Remain Solvent”

— John Maynard Keynes

This timeless quote is a powerful reminder for investors and traders alike.

Markets don’t move only on logic or fundamentals.
They are driven by sentiment, emotion, liquidity, and human behaviour.
Trying to fight the market with leverage, ego, or overconfidence can be far more dangerous than being temporarily wrong.

The real lesson is simple:
Risk management matters more than predictions.
Survival in the market always comes before returns.

Those who respect uncertainty, control exposure, and stay disciplined are the ones who last long enough to benefit when rationality finally returns.

Facebook IPO: Valuation at Approx. $100 Billion

The Facebook IPO has been pegged at an approximate valuation of $100 billion, making it one of the largest IPOs in history. However, I believe this valuation is driven more by hype than solid fundamentals.

At a $100 billion valuation, Facebook would be trading at:

• Price-to-Earnings (P/E) multiple of approximately 77

• Price-to-Sales (P/S) multiple of about 25

The Key Assumptions Behind the $100B Valuation

While the official offer price and exact earnings estimates are still unknown, we can make reasonable assumptions based on available disclosures:

1. Facebook is valued at $100 billion

   • This is nearly twice the valuation of Boeing and about three times that of Starbucks.

2. Facebook has 1 billion monthly active users

   • Each user generates about $4.25 per year.

3. Operating margins remain around 30%

Based on these numbers, Facebook could generate:

• $4.25 billion in annual revenue

• Approximately $1.3 billion in net earnings

At this level, Facebook would trade at:

• P/E = 77

• P/S = 25

Can Facebook Replicate Google’s Success?

Google’s IPO in 2004 was a major success for long-term investors. The company became one of the world’s greatest businesses. Google’s stock price has increased nearly 7-fold since its IPO. More importantly, Google grew into its expensive valuation.

Can Facebook replicate this success story? That’s the big question.

The Comparison with Google

While Google and Facebook share similar ad-driven business models, there are significant differences between the two.

When Google went public, it was valued at a similar P/E multiple but at only 5x sales. Today, Google trades at $600 per share, compared to its IPO price of $85. This makes Facebook’s pricing appear attractive. However, we are projecting Google’s 8-year extraordinary success onto Facebook, which may be unrealistic.

Why Google’s IPO Was Successful

At the time of its IPO, Google earned around $400 million on $3.2 billion in revenue. Fast forward to 2011, and:

• Google’s revenue reached $38 billion

• Its net earnings approached $10 billion

This represented a 36% annual revenue growth and ~40% annual earnings growth. Despite strong returns, Google now trades at:

• P/E ~20

• P/S ~5

In short, Google became cheaper over time, even as its business grew dramatically.

Why Facebook May Disappoint IPO Buyers

While Google’s IPO was undervalued, allowing for future upside, there are no signs of underpricing in Facebook’s IPO. Institutional investors might get shares at the listed price, but retail investors could face 20-40% premiums once trading begins.

Key Differences Between Google and Facebook

1. Business model:
   Google’s model has not gone out of fashion. It monetizes search intent, which is highly valuable.

   Facebook, on the other hand, monetizes social behavior, which can be more volatile and less predictable.

2. Growth Ceiling:
   Facebook is already a much more mature company at IPO compared to Google. With 1 billion users, Facebook already reaches ~14% of the global population (including those without reliable internet access). This limits room for user base growth, and forces Facebook to rely heavily on monetization innovation, which carries risks.

Bottom Line:

Facebook is not Google, despite surface similarities. Google’s future growth was visible at IPO: more searches meant more ad revenue. Facebook’s future growth depends on continuous reinvention, as its user growth inevitably plateaus.

Sometimes, it is wiser to watch the story unfold rather than invest based on hype. If Facebook truly becomes the next Google, there will be plenty of opportunity to invest after the IPO dust settles.

For now, my recommendation: Take a pass.

Amazon enters India via Junglee.com

So, the news is that Amazon has entered India through Junglee.com. Amazon had, in fact, already acquired Junglee back in 1998 for $140 million.

Today, Amazon is one of the most successful internet companies in the world. This move is being closely watched because the Indian e-commerce market is still in a nascent stage, yet it holds enormous potential — estimates point to a $400+ billion opportunity over time. The pie is huge, and it is only expected to grow.

But for Junglee to rule the jungle… well, that may take some time.

The first impression of Junglee.com is quite disappointing. The site is still marked as beta, but coming from Amazon, expectations were naturally higher. Frankly, it doesn’t encourage browsing beyond the first page.

Personally, I have used Infibeam and Flipkart, and I would say these two are among the best e-commerce platforms in India at present. They offer strong service levels and features like cash-on-delivery, which works extremely well in the Indian market.

Now, Junglee.com itself will not sell products directly. Instead, it redirects customers to online and offline vendors. Sounds interesting — big promises — but several questions arise:

• What about returns and refunds?

• How will customer care be handled?

• What about service quality and product authenticity?

Is the focus primarily on earning sales commissions by onboarding as many vendors as possible and then building the marketplace from there? If so, that approach may not be as easy as it sounds.

For me, this remains a wait-and-watch situation.

And by the way… I need to rush back to my current e-commerce sites to search for my favourite book.
Till then — good luck, Junglee!

Understanding the Free Rider Problem

A free rider is someone who enjoys the benefits of a group effort without contributing anything in return. While this might seem harmless, it leads to significant issues in various areas of society, especially in economics and business.

The Free Rider Problem arises when individuals take advantage of a system without participating, which often leads to underproduction or non-production. This occurs because contributors feel discouraged when others are receiving the same rewards without effort.

Example of the Free Rider Problem in Sports

Let’s consider the example of a cricket series. When a team wins a major tournament, such as the ICC World T20, every player in the squad typically receives rewards and recognition. However, this includes players who contributed little to the victory — sometimes without even playing a single match.

For example, during India’s win in the ICC World T20, certain players were awarded substantial sums of money, despite not playing. These free riders enjoyed the rewards without contributing meaningfully to the team’s success.

The Real Problem with Free Riders

The issue grows when free riders take their position for granted and assume they will continue to receive rewards without making an effort. Over time, if this behaviour spreads, it can affect the entire system — be it a sports team or a company — leading to:

• Declining performance among all members

• Demotivation of contributors who feel their hard work is undervalued

• Collapse of the system when the imbalance becomes too great to maintain

Law of Unintended Consequences

Unintended consequences refer to the unforeseen outcomes that arise from a specific action, often completely contrary to the initial intentions. These consequences can have lasting and far-reaching effects.

The Cold War Example: Unintended Consequences

A classic example of unintended consequences occurred during the Cold War. The United States supported Afghan rebels in their fight against the Soviet Union in the 1980s. While this action was aimed at weakening the Soviet Union, it led to the creation of several militant groups that would eventually turn against the United States.

After the Cold War ended in the early 1990s, and with the Soviet Union collapsing, the United States withdrew its support from the Afghan rebels. However, the weapons and military training provided to these groups led to their eventual radicalization.

In the years following, some of these trained groups became enemies of the U.S. and were later involved in the September 11 attacks on the World Trade Center in 2001.

---

The Ripple Effect of Actions

Both the Free Rider Problem and the Law of Unintended Consequences teach an important lesson in economics and public policy. Actions, even if well-intentioned, often have unexpected ripple effects beyond their initial goals. Ignoring these broader impacts can be costly, leading to negative consequences in the long run.

---

Conclusion: The Broader Lessons

Whether in economics, business, or politics, understanding the Free Rider Problem and the Law of Unintended Consequences is crucial. These concepts remind us to consider the long-term impacts of our actions and recognize how seemingly harmless behaviours can have far-reaching consequences.

“The moment you feel the need to tightly manage someone, you have made a hiring mistake. The best people don’t need to be managed. They need guidance, leadership, and mentorship.”
— Jim Collins

In any organization, there are typically four types of people:

1. Problem Child – High Potential, Low Performance

2. Star Performers – High Potential, High Performance

3. Deadwood – Low Potential, Low Performance

4. Workaholic – Low Potential, High Performance

Who Gets the Maximum Attention?

This question is crucial.
In many organizations, the Problem Child often receives the most attention. Why? Because they show potential but fail to perform. It’s similar to the first-child theory in a family. The first child usually gets all the attention until the second one arrives. Then, challenges arise.

The Role of Managers

Managers have a critical role to play. Their responsibility goes beyond just managing performance. They need to develop plans and programs that enhance the human capacity of the organization, enabling it to meet future challenges and deliver superior economic value.

Focus on Star Performers

The focus should be on identifying, nurturing, and retaining star performers.
These are the individuals who drive business growth and are key to an organization’s long-term success.

Shifting HR Strategy

Human Resources (HR) is no longer just a department.
It is now the responsibility of every manager in the organization. The role of HR has evolved from operational and administrative tasks to strategic ones.

Here’s how the shift looks:

• Operational → Strategic

• Qualitative → Quantitative

• Policing → Partnering

• Short-term → Long-term

• Administrative → Consultative

• Functionally oriented → Business oriented

• Internally focused → Externally & customer focused

• Reactive → Proactive

• Activity focused → Solutions focused

The Effective HR Strategy

An effective human resource strategy focuses on identifying star performers and aligning people management with long-term business strategy. Managers must ensure that talent is nurtured and that employees are provided with clear growth opportunities.

This approach encourages innovation, better performance, and ultimately, business success.

Analyzing and deriving insights from financial statements is one of the most interesting aspects of understanding a business. A financial statement can be interpreted in many different ways depending on the role and perspective of the reader.

In Part I, we looked at three lenses through which financial statements can be viewed. Below are three more important perspectives.

4. AUDITOR

An auditor’s primary objective is to express an opinion on the fairness of financial statements in accordance with generally accepted accounting principles.

As an auditor, the focus is on obtaining reasonable assurance that the financial statements are free from material misstatements, whether due to error or fraud. Financial statement analysis helps auditors:

• Identify potential errors or irregularities

• Highlight unusual trends or inconsistencies

• Understand the company’s operations in the context of industry and economic conditions

Financial statement analysis is especially useful as a preliminary audit tool, directing the auditor’s attention to areas showing significant variation, abnormal performance, or unexplained changes.

5. RISK ANALYST

Accounting risk arises due to the judgments, estimates, and assumptions inherent in the accounting process. These elements introduce uncertainty into financial reporting and decision-making.

Key aspects of accounting risk include:

• The degree of conservatism or optimism in accounting assumptions

• Subjectivity in estimates such as provisions, depreciation, or asset valuation

• Sensitivity of reported results to changes in assumptions

For a risk analyst, understanding these assumptions is critical, as overly conservative or aggressive accounting can materially distort the perception of a company’s financial health.

6. YOU ARE THE ANALYST / FORECASTER

From an analyst or forecaster’s perspective, the focus is on earnings persistence — the degree to which earnings are recurring, stable, and predictable.

More persistent earnings typically arise from core operating activities. For example:

• If a large portion of earnings (say 40%) comes from unusual or non-operating gains, earnings persistence is lower

• Items classified as “unusual” (such as litigation gains) may sometimes be better viewed as extraordinary, depending on the nature of the business

• Extraordinary losses also reduce earnings persistence

In such cases, even if aggregate earnings show a steady growth trend, the underlying composition suggests higher uncertainty. This lower persistence should be reflected in both:

• The level of expected earnings, and

• The degree of uncertainty in earnings forecasts

Gaining insights into an organisation’s financial statements is ultimately a matter of perspective.
Analyzing the same company through different lenses can lead to very different conclusions — and that is precisely why understanding these perspectives is so important.
