Investment Risk and Return

One of the major concepts that most investors should be aware of is the relationship between the risk and the return of a financial asset. It is common knowledge that there is a positive relationship between the risk and the expected return of a financial asset. In other words, when the risk of an asset increases, so does its expected return. What this means is that if an investor is taking on more risk, he/she is expected to be compensated for doing so with a higher return. Similarly, if the investor wants to boost the expected return of the investment, he/she needs to be prepared to take on more risk.

PORTFOLIO ALPHA: https://medicalexecutivepost.com/2025/07/02/managing-for-endowment-portfolio-alpha/

Harry Max Markowitz (August 24, 1927 – June 22, 2023) was an American economist who was a professor of finance at the Rady School of Management at UCSD. He is best known for his pioneering work in modern portfolio theory, studying the effects of asset risk, return, correlation and diversification on probable investment portfolio returns.

One important thing to understand about Modern Portfolio Theory (MPT) is Markowitz’s calculations treat volatility and risk as the same thing. In layman’s terms, Dr. Markowitz uses risk as a measurement of the likelihood that an investment will go up and down in value – and how often and by how much. The theory assumes that investors prefer to minimize risk. The theory assumes that given the choice of two portfolios with equal returns, investors will choose the one with the least risk. If investors take on additional risk, they will expect to be compensated with additional return.

According to MPT, risk comes in two major categories:

  • Systematic risk – the possibility that the entire market and economy will show losses negatively affecting nearly every investment; also called market risk
  • Unsystematic risk – the possibility that an investment or a category of investments will decline in value without having a major impact upon the entire market.

Diversification generally does not protect against systematic risk because a drop in the entire market and economy typically affects all investments. However, diversification is designed to decrease unsystematic risk. Since unsystematic risk is the possibility that one single thing will decline in value, having a portfolio invested in a variety of stocks, a variety of asset classes and a variety of sectors will lower the risk of losing much money when one investment type declines in value. Thus putting together assets with low correlations can reduce unsystematic risks.

a.   Understanding the Risk

Although broad risks can be quickly summarized as “the failure to achieve spending and inflation-adjusted growth goals,” individual assets may face any number of other subsidiary risks:

  • Call risk – The risk, faced by a holder of a callable bond that a bond issuer will take advantage of the callable bond feature and redeem the issue prior to maturity. This means the bondholder will receive payment on the value of the bond and, in most cases, will be reinvesting in a less favorable environment (one with a lower interest rate)
  • Capital risk – The risk an investor faces that he or she may lose all or part of the principal amount invested.
  • Commodity risk – The threat that a change in the price of a production input will adversely impact a producer who uses that input.
  • Company risk – The risk that certain factors affecting a specific company may cause its stock to change in price in a different way from stocks as a whole.
  • Concentration risk – Probability of loss arising from heavily lopsided exposure to a particular group of counterparties
  • Counterparty risk – The risk that the other party to an agreement will default.
  • Credit risk – The risk of loss of principal or loss of a financial reward stemming from a borrower’s failure to repay a loan or otherwise meet a contractual obligation.
  • Currency risk – A form of risk that arises from the change in price of one currency against another.
  • Deflation risk – A general decline in prices, often caused by a reduction in the supply of money or credit.
  • Economic risk – the likelihood that an investment will be affected by macroeconomic conditions such as government regulation, exchange rates, or political stability.
  • Hedging risk – Making an investment to reduce the risk of adverse price movements in an asset.
  • Inflation risk – The uncertainty over the future real value (after inflation) of your investment.
  • Interest rate risk – Risk to the earnings or market value of a portfolio due to uncertain future interest rates.
  • Legal risk – risk from uncertainty due to legal actions or uncertainty in the applicability or interpretation of contracts, laws or regulations.
  • Liquidity risk – The risks stemming from the lack of marketability of an investment that cannot be bought or sold quickly enough to prevent or minimize a loss.

CONVERTIBLE ARBITRAGE: Defined

Posted on April 13, 2025 by Dr. David Edward Marcinko MBA MEd CMP™

Convertible Arbitrage

Convertible arbitrage is the oldest market-neutral strategy. Designed to capitalize on the relative mispricing between a convertible security (e.g. convertible bond or preferred stock) and the underlying equity, convertible arbitrage was employed as early as the 1950s.

Since then, convertible arbitrage has evolved into a sophisticated, model-intensive strategy, designed to capture the difference between the income earned by a convertible security (which is held long) and the dividend of the underlying stock (which is sold short). The resulting net positive income of the hedged position is independent of any market fluctuations. The trick is to assemble a portfolio wherein the long and short positions, responding to equity fluctuations, interest rate shifts, credit spreads and other market events offset each other.

***

Hedge Fund Research (HFR) New York, offers the following description of the strategy

Convertible Arbitrage involves taking long positions in convertible securities and hedging those positions by selling short the underlying common stock. A manager will, in an effort to capitalize on relative pricing inefficiencies, purchase long positions in convertible securities, generally convertible bonds, convertible preferred stock or warrants, and hedge a portion of the equity risk by selling short the underlying common stock. Timing may be linked to a specific event relative to the underlying company, or a belief that a relative mispricing exists between the corresponding securities. Convertible securities and warrants are priced as a function of the price of the underlying stock, expected future volatility of returns, risk free interest rates, call provisions, supply and demand for specific issues and, in the case of convertible bonds, the issue-specific corporate/Treasury yield spread. Thus, there is ample room for relative mis-valuations.

Because a large part of this strategy’s gain is generated by cash flow, it is a relatively low-risk strategy.

Credit analysis is a form of financial analysis used primarily to determine the financial strength of the issuer of a security, and the ability of that issuer to provide timely payment of interest and principal to investors in the issuer’s debt securities. Credit analysis is typically an important component of security analysis and selection in credit-sensitive bond sectors such as the corporate bond market and the municipal bond market.

Credit default swap index (CDX) is a credit derivative, based on a basket of CDS, which can be used to hedge credit risk or speculate on changes in credit quality.

Credit default swaps (CDS) are credit derivative contracts between two counterparties that can be used to hedge credit risk or speculate on changes in the credit quality of a corporation or government entity.

Credit quality reflects the financial strength of the issuer of a security, and the ability of that issuer to provide timely payment of interest and principal to investors in the issuer’s securities. Common measurements of credit quality include the credit ratings provided by credit rating agencies such as Standard & Poor’s and Moody’s. Credit quality and credit quality perceptions are a key component of the daily market pricing of fixed-income securities, along with maturity, inflation expectations and interest rate levels.

Credit Rating Agency (CRA) is a company that assigns credit ratings for issuers of certain types of debt obligations as well as the debt instruments themselves. In the United States, the Securities and Exchange Commission (SEC) permits investment banks and broker-dealers to use credit ratings from “Nationally Recognized Statistical Rating Organizations” (NRSRO) for similar purposes. As of January 2012, nine organizations were designated as NRSROs, including the “Big Three” which are Standard and Poor’s, Moody’s Investor Services and Fitch Ratings.

Credit rating downgrade, by a credit rating agency (Standard & Poor’s, Moody’s or Fitch) means reducing its credit rating for a debt issuer and/or security. This is based on the agency’s evaluation, indicating, to the agency, a decline in the issuer’s financial stability, increasing the possibility of default. A downgrade should not to be confused with a default; a debt security can be downgraded without defaulting. And, conversely, a debt issuer can suddenly default without being downgraded first–credit ratings and credit rating agencies are not infallible.

Credit ratings are measurements of credit quality provided by credit rating agencies. Those provided by Standard & Poor’s typically are the most widely quoted and distributed, and range from AAA (highest quality; perceived as least likely to default) down to D (in default). Securities and issuers rated AAA to BBB are considered/perceived to be “investment-grade”; those below BBB are considered/perceived to be non-investment-grade or more speculative.

Credit risk is the inability or perceived inability of the issuers of debt securities to make interest and principal payments will cause the value of those securities to decrease. Changes in the credit ratings of debt securities could have a similar effect.

Credit Risk Transfer Securities (CRTS) are unsecured obligations of the GSEs (Government Sponsored Enterprises). Although cash flows are linked to prepays and defaults of the reference mortgage loans, the securities are unsecured loans, backed by general credit rather than by specified assets.

DEFINITIONS

What Is CREDIT? Credit is a contractual agreement in which a borrower receives a sum of money or something else of value and commits to repaying the lender later, typically with interest. Credit is also the creditworthiness or credit history of an individual or a company. Good credit tells lenders you have a history of reliably repaying what you owe on loans. Establishing good credit is essential to getting a loan.
