Insider investment strategy

Insider investment strategy is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Insider investment strategy rather than just read about it. In short: The insider investment strategy is an investment strategy that follows the buying and selling decisions of so-called "insiders" in a stock market. The primary insiders have an advantage because they have access to more information about issues that could affect the current and future value of stock, which is known as an "information advantage." However, in the world there are only a few investment funds that follow…

Key takeaways

Insider investment strategy belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Insider investment strategy to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Insider investment strategy from memory before moving on to harder problems.

Reference excerpt

The insider investment strategy is an investment strategy that follows the buying and selling decisions of so-called "insiders" in a stock market. The primary insiders have an advantage because they have access to more information about issues that could affect the current and future value of stock, which is known as an "information advantage." However, in the world there are only a few investment funds that follow the insider trades, both of them were established in 2011. In the United States, Catalyst Capital Advisors LLC manages Catalyst Insider Buying Fund. This fund is a large-cap, long-only equity fund that only invests in companies where corporate insiders are buying their own company's stock on the open market. In Europe, Dovre Forvaltning UAB manages Dovre Inside Nordic fund.

Effectiveness A Lorie-Niederhoffer study indicates that proper and prompt analysis of data on insider trading can be profitable. In 2014, Dovre Forvaltning shared his analysis on Insider Influence in the Nordic Region. The company analyzed these different yearly portfolios (both for purchases and sales):

Had an insider purchases in the past 1/3/6 months Had only insider purchases in the past 1/3/6 months Last insider transaction in the past 1/3/6 months was an insider purchase Had an insider sales in the past 1/3/6 months Had only insider sales in the past 1/3/6 months Last insider transaction in the past 1/3/6 months was an insider sale Only transactions above 80,000 SEK were included (33% of all insider trades were excluded because they were too small). If there were no purchases/sales in 1,3,6 months after a company's inclusion, it was excluded from the portfolio. All stocks are equally weighted. The analysis showed that:

Highest out performance was in small caps insider purchase portfolios, smaller in mid caps purchase portfolios, and smallest in large caps insider purchase portfolios. 'Insider effect' fades away with longer holding horizon. Sell signals are stronger than buy signals. Sell signals are the strongest when more than 50% of holdings are sold. Buy signals are the strongest when signal transaction value is less than 80,000 SEK.

Worked examples

Example 1 — a first encounter with Insider investment strategy

Start with the simplest possible case. Write down what Insider investment strategy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Insider investment strategy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Insider investment strategy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Insider investment strategy

In research: Insider investment strategy appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Insider investment strategy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Insider investment strategy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Actuarial science, Investment management, so understanding it makes those chapters shorter.
In everyday life: Look for Insider investment strategy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
