Study Notes
Correlation Methods
- Rank correlation methods include the Spearman rank correlation coefficient and Kendall’s Tau, providing alternatives to Pearson correlation.
- Non-parametric methods of correlation do not rely on the distributions of underlying risk variables, making them more robust in certain scenarios.
- Rank coefficients are less sensitive to outliers compared to Pearson correlation, leading to potentially clearer dependency insights.
Causation and Dependency
- Correlation measures numerical dependency but does not fully characterize the structure of that dependency.
- Zero correlation does not imply independence; dependent variables can still exhibit a correlation score of zero.
- Possible relationships between correlated variables include mutual causation, common causes, or mere coincidence.
- The phrase "correlation does not imply causation" encapsulates the idea that observed correlations do not confirm causal relationships.
Criteria for Causation
- For one variable to cause another, three conditions must be met:
- The cause must precede the effect in time.
- The effect must occur exclusively as a result of the cause.
- There should be no other external factors influencing the relationship.
Fundamental Analysis
- Fundamental analysis aims to assess an asset's intrinsic value based on financial statements and market comparisons.
- Key figures in the development of this method include Benjamin Graham and David Dodd, renowned for their influential work "Security Analysis," published in 1934.
- Analysts evaluate historical data and external conditions to determine stock value, guiding investment decisions.
Modern Portfolio Theory
- Introduced by Harry Markowitz in 1952, modern portfolio theory emphasizes the trade-off between portfolio return and risk (variance).
- The theory has evolved to incorporate repo agreements for managing central bank and commercial bank transactions.
Central Banking and Monetary Policy
- Central banks provide liquidity to commercial banks and influence money supply through mechanisms like interest rate adjustments.
- The central bank can create money by purchasing assets from banks, increasing the circulating money supply and encouraging lending.
- Monetary policy typically focuses on inflation targeting, although exchange rate targeting exists, especially in developing economies.
- Money serves three primary functions:
- Medium of exchange
- Mechanism for storing wealth
- Unit of account
Money in the Modern Economy
- Money functions as a universally accepted IOU, representing trust across various economic sectors.
- There are three principal forms of money: currency, bank deposits, and central bank reserves, with bank deposits being the most prevalent.
- Trust in money allows for fluid exchanges of goods and services, essential for a modern economy's operation.
