Insider Sentiment Score

The Insider Sentiment Score finds the companies being bought by corporate insiders.

It is the result of a sophisticated, multi-factor quantitative model that identifies companies with the highest levels of insider accumulation. The scoring model uses a combination of the net number of insiders buying the prior 90 days, the total shares bought as a percentage of float, and the total shares owned by insiders. The number ranges from 0 to 100, with higher numbers indicating a higher level of accumulation to its peers, and 50 being the average.

Update Frequency: Daily

See Insiders Top Picks, which provides a list of companies with highest insider accumulation.

Officer Sentiment Score

The Officer Sentiment Score finds companies being bought by Corporate Officers.

By definition Corporate Officers are Corporate Insiders, but unlike some of the other Insiders (10% Shareholders and Board Members), Officers work for the company on a daily basis, and they user their own money when trading. (10% Shareholders and Board Members are often fund managers managing other people’s money.) As such, insider trades made by Officers are much more significant and should be treated appropriately.

Like the Insider Sentiment Score, the Officer Sentiment Score is the result of a sophisticated, multi-factor quantitative model that identifies companies with the highest levels of officer accumulation.

Key Insider Metrics

This card shows how the company ranks along various insider metrics. The percentile rank shows how this company compares to other companies in the US markets. Higher rankings are indicative of better situations.

For example, it is generally accepted that insider buying is a positive indicator, so companies with more insider buying would rank higher than companies with less insider buying (or even insider selling).

Net Number of Insiders Buying (Rank)

N/A

Net Number of Insiders Buying is the total number of insiders buying minus the total number of insiders selling in the last 90 days. The percentile rank is shown here (range from 0 to 100%).

Percent of Float Bought by Insiders (Rank)

N/A

Percent of Float Bought by Insiders is the total number of shares purchased by insiders minus the total number of shares sold by insiders in the last 90 days, divided by the total float and multiplied by 100.

Insider Trading Chart

MaxCyte Inc insider trades are shown in the following chart. Insiders are officers, directors, or significant investors in a company. In general, it is generally illegal for insiders to make trades in their companies based on material, non-public information. This does not mean it is illegal for them to make any trades in their own companies. However, they must report all trades to the SEC via a Form 4.

Insider Roster and Profitability Metrics

This table shows the list known insiders, and is generated automatically from filings disclosed to the SEC. In addition to the names, most recent title, and director, officer, or 10% owner designation, we provide the latest disclosed holdings. Additionally, when possible we provide the historical trade performance for the insider. The historical trade performance is a weighted average of the performance of actual open-market purchase transactions made by the insider. For more information on how this is calculated, watch this YouTube webinar.
