IMPROVING FINANCE EDUCATION
Many ideas traditionally taught in finance and economics classrooms are either incomplete, misleading, or too detached from real-world market behaviour. This is because academic models in finance have often prioritised mathematical elegance over practical accuracy.
Major "Mistakes" We Teach
1. Markets Are Fully Efficient
Finance theory tells us that prices instantly reflect all available information and that it is impossible to beat the market consistently.
According to Jay Ritter:
Examples of market inefficiency include:
While the Efficient Markets Hypothesis (EMH) is a useful benchmark, it is not a literal description of reality.
2. Risk Equals Volatility
Finance theory teaches us that risk is measured by standard deviation and beta.
Ritter's critique is that volatility is often a poor proxy for risk.
Permanent capital loss matters more than price fluctuations. A stock's temporary price decline becomes risky only if there is a structural disruption.
In other words, real risks include:
Investment risk is multidimensional and therefore cannot be equated with volatility alone.
3. Higher Risk Always Produces Higher Return
The standard axiom of finance is that investors are compensated for bearing more risk.
Ritter argues that, empirically, many "risky" assets actually underperform. For example:
These investments often disappoint investors.
The behavioural explanation is that investors tend to overpay for exciting stories and skewed upside potential. Investors are often overconfident, and there are limits to rationality.
4. Investors Are Rational
Classical economics assumes that investors are rational economic agents who optimize logically.
In reality, investors rely on heuristics and are subject to biases and emotions that influence their decisions.
What Finance Education Should Teach
Ritter advocates a broader approach to finance education. Financial education should embrace a comprehensive framework that combines the following:
1. Theory
Theory provides useful abstractions and conceptual frameworks, but it should not be mistaken for reality.
2. Behaviour
An understanding of human behaviour is essential for students of finance. Psychology and behavioural biases play a major role in financial decision-making.
3. Historical Perspective
A study of financial history provides valuable perspective. Past bubbles, crashes, and market cycles offer important lessons for investors and managers.
4. Institutional Knowledge
Knowledge of the institutional framework and the regulatory apparatus governing financial markets is indispensable for understanding how markets actually function.
5. Probabilistic Thinking
Given the uncertainty characterising the real world, students of finance must develop probabilistic thinking. Financial decisions should be based on probabilities rather than certainty.
Conclusion
To sum up, finance should be taught as a probabilistic social science, not as physics. Theory remains important, but it must be complemented by behavioural insights, historical experience, institutional understanding, and probabilistic reasoning to prepare students for real-world financial decision-making.

Impact of the Announcement of SEO on Stock Price
The stock price of a firm tends to decline when the firm announces a new issue of equity. Why? There are three plausible reasons for this strange result.
The drop in stock price following the announcement of a new equity issue is about 3 percent for an industrial corporation and it is somewhat smaller for a public utility. This drop is called abnormal return in the context of the costs of new issues.
Dilution
When a company issues new equity, the subject of dilution generally comes up. There are several kinds of dilution:
Though the word “dilution” has a negative connotation, only dilution of stock price is really bad.
Swap Pricing
How does the market set prices for swaps (interest rate swaps, currency swaps, or credit default swaps)? Without getting into details, let us emphasise the basic point: Swaps, like forwards and futures, are zero – sum transactions. This means that the market sets prices in such a manner that when the deal is struck it is a fair deal, with neither party having an advantage. For example the rates in an interest rate swap are set as the fair fixed and floating rates, considering the credit worthiness of the counterparties. Likewise, the currency swap may be viewed as a series of forward contracts. In a credit default swap, the rate is based on the default rate for a particular bond over a particular time.

Superior- Subordinate Relationship
Superior, “You must work hard.”
Subordinate, “Sir, I will hardly work.”
Superior, “Look over the details.”
Subordinate, “Sir, I will overlook the details.”
Superior, “You stand out.”
Subordinate, “Sir, I’m outstanding.”
Lottery- Refund
Anthony bought a lottery ticket and luckily was selected for the prize that was a whopping Rs. 20 lakhs. When he presented the ticket he was told that he will be paid Rs. 1 lakh per week for 20 weeks. Exasperated, he said “Give me Rs. 20 lakhs immediately or else refund Rs. 5 the cost of the lottery ticket.”
