Connected Business Concepts

Value Investing

Value investing is a strategy advocating the purchase of stocks that are underappreciated by other investors or the broader market. Value investing was popularised by investor Warren Buffett, but the approach was pioneered by Benjamin Graham and David Dodd at Columbia Business School in the early 1920s. Graham would later go on to release the seminal book The Intelligent Investor in 1949.

Buffet Indicator

The Buffet Indicator is a measure of the total value of all publicly-traded stocks in a country divided by that country’s GDP. It’s a measure and ratio to evaluate whether a market is undervalued or overvalued. It’s one of Warren Buffet’s favorite measures as a warning that financial markets might be overvalued and riskier.

Circle of Competence

The circle of competence describes a person’s natural competence in an area that matches their skills and abilities. Beyond this imaginary circle are skills and abilities that a person is naturally less competent at. The concept was popularised by Warren Buffett, who argued that investors should only invest in companies they know and understand. However, the circle of competence applies to any topic and indeed any individual.

Economic Moat

Economic or market moats represent long-term business defensibility. Or how long a business can retain its competitive advantage in the marketplace over the years. Warren Buffet who popularized the term “moat” referred to it as a share of mind, opposite to market share, as such it is the characteristic that all valuable brands have.

Golden Circle

The Golden Circle attempts to explain how certain businesses can inspire others and differentiate themselves in the market. Originally developed by author Simon Sinek, the concept helps businesses identify their purpose and then communicate that purpose to consumers in a meaningful way so that the brand can be highly differentiated in the marketplace.

5 Whys Method

The 5 Whys method is an interrogative problem-solving technique that seeks to understand cause-and-effect relationships. At its core, the technique is used to identify the root cause of a problem by asking the question of why five times. This might unlock new ways to think about a problem and therefore devise a creative solution to solve it.

First-Principle Thinking

First-principles thinking – sometimes called reasoning from first principles – is used to reverse-engineer complex problems and encourage creativity. It involves breaking down problems into basic elements and reassembling them from the ground up. Elon Musk is among the strongest proponents of this way of thinking.

Second-Order Thinking

Second-order thinking is a means of assessing the implications of our decisions by considering future consequences. Second-order thinking is a mental model that considers all future possibilities. It encourages individuals to think outside of the box so that they can prepare for every and any eventuality. It also discourages the tendency for individuals to default to the most obvious choice.
