Analysis of insider trades is Investtech’s alternative to fundamental analysis. When persons on a company’s Board or in management buy stocks, it signals that they think the stock is cheap. Insider sales are considered a signal that the stock is expensive or high risk.
Investtech’s insider trade analyses give an overview of insider purchases and insider sales in a company over time.
Each trade is assigned an importance on a scale from 0 to 100. Big trades count more than small ones, and trades where the insiders owned few stocks to start with, are given more weight than where they owned many. An insider purchase gives a positive number and sales give a negative number.
In Norway all registered insiders are obliged to report their own trades as soon as possible, and no later than when the exchange opens the next day. Investtech evaluates all stock exchange messages and registers data on insider trades. The insider trade analysis for Swedish stocks is based on the insider transactions reported
to the Swedish Financial Supervisory Authority’s Insider Register.
Based on all reported insider trades in a company, Investtech’s systems assign the stock an insider ranking on the scale -100 to +100. Stocks with an insider ranking of 50 or higher are considered buy candidates based on insider trades. Insider rankings from 25 to 50 are considered weak buy candidates. Similarly, negative insider rankings are
considered sell candidates.

Aksjer med innsidekjøp har i gjennomsnitt gjort det bedre enn referanseindeksen i perioden etter innsidekjøpet, og aksjer med innsidesalg har i gjennomsnitt gjort det dårligere enn referanseindeksen i perioden etter innsidesalget. Det viser en forskningsrapport fra Investtech basert på 20 år med data fra Oslo Børs og 16 år med data fra Stockholmsbørsen.
Analyse av innsidehandler er Investtechs alternativ til fundamental analyse. Når en person i selskapets styre eller ledelse kjøper aksjer, er det et signal om at vedkommende mener aksjen er billig. Innsidesalg blir regnet som signal om at aksjen er dyr eller at risikoen er høy.
Investtechs innsidehandelanalyser gir oversikt over innsidekjøp og innsidesalg i et selskap over tid.

Figur 1: Kursutvikling første 66 dager etter innsidekjøp.
Grafene i figur 1 viser gjennomsnittlig kursutvikling i etterkant av innsidekjøp i Norge og Sverige. Handlene meldes før børsens stengetid på dag 0. Kun dager da børsen er åpen inngår, slik at 66 dager tilsvarer cirka tre måneder. Den tykke blå linjen viser hvordan aksjer med innsidekjøp i gjennomsnitt har utviklet seg. Det skraverte området angir standardavviket til beregningene. Den tynne blå linjen er gjennomsnittlig utvikling til referanseindeksen i samme periode.
66-dagers-tall | Norge | Sverige | Vektet snitt |
Kjøpssignal | 3.5 % | 4.3 % | 4.0 % |
Referanseindeks i samme periode | 2.2 % | 2.4 % | 2.3 % |
Meravkastning kjøpssignal | 1.4 %p | 1.8 %p | 1.7 %p |
Annualisert | |||
Kjøpssignal | 14.1 % | 17.3 % | 16.3 % |
Referanseindeks i samme periode | 8.5 % | 9.6 % | 9.2 % |
Meravkastning kjøpssignal | 5.7 %p | 7.7 %p | 7.2 %p |
Tabellen viser annualisert avkastning og annualisert meravkastning i prosentpoeng, benevnt %p. Innsidekjøp både i Norge og Sverige har vært fulgt av en positiv avkastning de kommende månedene. I Norge var oppgangen 3,5 prosent og i Sverige 4,3 prosent, som gir et vektet snitt på 4,0 prosent. Annualisert blir avkastningen 16,3 prosent, tilsvarende en meravkastning på 7,2 prosentpoeng mot referanseindeksen i samme periode.
Vi så også at aksjer med innsidekjøp i gjennomsnitt hadde falt i perioden før kjøpet. Motsatt hadde aksjer med innsidesalg steget i perioden før salget. Disse observasjonene er en indikasjon på at innsidere kjøper når de mener aksjene er fundamentalt billige, og har falt mer enn fortjent, samtidig som innsiderne selger når de mener aksjen har steget for mye og har blitt fundamentalt dyr. Investtechs innsidehandelanalyse kan dermed ses på som en enkel fundamental analyse av aksjen.

When primary insiders in a company buy stocks, it may be a signal that the stock is fundamentally cheap.
When someone on a company’s Board or a member of Management buys stocks, it signals that they think the stock price will rise. The primary insider may feel that the market has punished the stock too hard following negative news or that the market fails to sufficiently value positive news. It may also be the case that the company’s outlook is good and/or that the insider believes the purchase risk is low.
In general, we want to side with the primary insiders. It is considered safer to buy a stock that the company’s directors or management have purchased recently than a similar stock without insider trades.
Stocks with these ostosignaalit have on average outperformed the market in the following months. Annualised excess return has been 8.1 percentage points (pp). This is significantly better than benchmark.

Sales by primary insiders in a company may be a signal that the stock is fundamentally expensive.
When someone on a company’s Board or a member of Management sells stocks, it may be a signal that they are afraid the stock price will fall. The primary insider may think the stock has risen too much compared to the development and potential of the company, or that the market has failed to sufficiently take into account increased risk or negative news. It may also be the case that the company’s or sector’s outlook has been weakened or that the insider believes risk is high.
If the insider only sells a smaller share of their stocks, they may want to reduce risk in their own portfolio. Sales may also occur because an insider needs cash for something else or has found a better investment opportunity. In general, it is considered a negative signal when primary insiders sell stocks in their company. It is considered safer to buy a stock where directors or management have purchased stocks recently than similar stocks where insiders have recently sold.
