Noise trader is generally a term used in academic finance studies associated with the Efficient Markets Hypothesis (EMH). The definition is often vaguely stated throughout the literature though it is mainly intended to describe investors who make decisions to buy or sell based on factors they believe to be helpful but in reality will give them no better returns than random choices.

Definition

Noise traders are investors who buy and sell based on factors they believe will aid their investment decisions, but these factors do not actually yield better returns than random choices. This term is often used in academic financial research, particularly in discussions related to the Efficient Market Hypothesis (EMH).

Origin

The concept of noise traders originated in the 1980s and gained prominence with the rise of behavioral finance. In 1986, economist Fischer Black introduced the concept of 'noise trading' in his paper, highlighting the presence of irrational trading behaviors in the market that could cause prices to deviate from their fundamental values.

Categories and Features

Noise traders can be categorized into various types, including investors who trade based on emotional fluctuations, those who rely on market rumors or informal information, and overconfident investors. The common feature among these traders is the lack of a systematic analytical approach, making them susceptible to market sentiment and short-term fluctuations.

Case Studies

A typical case is the dot-com bubble of 2000, where many investors blindly followed market trends to buy tech stocks without thorough analysis, leading to significant losses. Another example is the 2021 GameStop event, where many retail investors, driven by social media, rushed to buy GameStop shares despite the company's fundamentals not supporting such high stock prices.

Common Issues

Investors often mistake short-term market fluctuations for the beginning of long-term trends, leading to poor investment decisions. Additionally, noise traders are prone to overconfidence, believing their intuition or informal information is more reliable than market analysis.

Labor Intensive

The term "labor-intensive" refers to a process or industry that requires a large amount of labor to produce its goods or services. The degree of labor intensity is typically measured in proportion to the amount of capital required to produce the goods or services: the higher the proportion of labor costs required, the more labor-intensive the business.

Fast-Moving Consumer Goods

Fast-moving consumer goods (FMCGs) are products that sell quickly at relatively low cost. FMCGs have a short shelf life because of high consumer demand (e.g., soft drinks and confections) or because they are perishable (e.g., meat, dairy products, and baked goods).They are bought often, consumed rapidly, priced low, and sold in large quantities. They also have a high turnover on store shelves. The largest FMCG companies by revenue are among the best known, such as Nestle SA. (NSRGY) ($99.32 billion in 2023 earnings) and PepsiCo Inc. (PEP) ($91.47 billion). From the 1980s up to the early 2010s, the FMCG sector was a paradigm of stable and impressive growth; annual revenue was consistently around 9% in the first decade of this century, with returns on invested capital (ROIC) at 22%.

Negotiable Instruments

A negotiable instrument is a signed document that promises a payment to a specified person or assignee. In other words, it is a formalized type of IOU: A transferable, signed document that promises to pay the bearer a sum of money at a future date or on-demand.Common examples of negotiable instruments include personal checks, cashier's checks, money orders, certificates of deposit (CDs), promissory notes, and traveler's checks. The person receiving the payment, known as the payee, must be named or otherwise indicated on the instrument. Because they are transferable and assignable, some negotiable instruments may trade on a secondary market.

Renewable Resource

A renewable resource is a resource that can be replenished naturally over time. As a result, it is sustainable despite its consumption by humankind.Renewable resources for the production of energy are considered especially important for their potential to replace non-renewable, or finite, resources. Additionally, renewable resources can offer cleaner energy solutions than those provided by non-renewable resources such as coal and fossil fuels.Examples of renewable resources include the sun, wind, water, the earth's heat (geothermal), and biomass.

Feasibility Study

A feasibility study is a detailed analysis that considers all of the critical aspects of a proposed project in order to determine the likelihood of it succeeding.Success in business may be defined primarily by return on investment, meaning that the project will generate enough profit to justify the investment. However, many other important factors may be identified on the plus or minus side, such as community reaction and environmental impact.Although feasibility studies can help project managers determine the risk and return of pursuing a plan of action, several steps should be considered before moving forward.
