Full Description

Insider ownership includes shares owned by a company’s officers and directors and any beneficial owners of a class of the company’s equity securities.

Standard & Poors gathers the data from a wide variety of public sources, including annuals, proxies, registration statements, press releases and direct insider reporting. The data is aggregated and updated once per month.


Coverage

Note that complete ownership data for these series begins around December 2004. Some data exists prior to that time in the database, but it has more holes and is not as consistently available across companies.


Timeliness

Ownership data is very fluid. A single insider transaction can occur on any day. Since we only expose aggregate data, though, an arbitrary period is used to snapshot the data.

For insider transaction data we use S&P monthly snapshots. These are done at the end of each month.

There are two notable exceptions: Insider#Own and Insider%Own factors. These factors are calculated daily by us and we then snapshot it once a week for historical simulations.


Factors

Factors are used directly in rules and ranking nodes and do not require further parameters. See the first example for a rule using factors.


Ins#ShrPurch: The total number of shares purchased over the last six months. It is a positive number in millions of shares. It is equal to InsiderBuySh6M(0).

Ins#ShrSold: The total number of shares sold over the last six months. It is a positive number in millions of shares. It is equal to InsiderSellSh6M(0).

InsNetShrPurch: The net number of shares bought and sold over the last six months. It is defined as Ins#ShrPurch less Ins#ShrSold; it is postiive if there were more bought shares and negative if there were more sold shares. It is in millions of shares, and is equal to InsiderBuySh6M(0) less InsiderSellSh6m(0).

InsBuyTrans: The total number of buy transactions by insiders over the last six months. It is a positive number. It is equal to InsiderBuyTran6M(0).

InsSelTrans: The total number of sell transactions by insiders over the last six months. It is a positive number. It is equal to InsiderSellTran6M(0).

InsNetTrans: The net number of insider transactions over the last six months. It is defined as InsBuyTrans less InsSellTrans; it is positive if there were more purchase transactions than sell transactions and negative if there were more sell transactions.

Insider#Own: The number of shares held by insiders, in millions of shares. Note that this factor is calculated daily by us and we then snapshot it once a week for historical simulations.

Insider%Own: The percentage of outstanding common shares owned by insiders, in percentage points. Note that this factor is calculated daily by us and we then snapshot it once a week for historical simulations.


Functions

Functions require parameters, contained in attached parentheses. Insider functions are generally displaying the sum of the transactions or shares for a number of months, as indicated in the name of the function.

Each of these functions has an offset, and that offset is in months.


InsiderBuySh1M(offset): The total number of shares purchased in one-month increments, in millions of shares.

InsiderBuySh3M(offset): The total number of shares purchased in three-month increments, in millions of shares. The offset is in months, so an offset of one will show the three-month total as it was one month ago.

InsiderBuySh6M(offset): The total number of shares purchased in six-month increments, in millions of shares. The offset is in months, so an offset of one will show the six-month total as it was one month ago.

InsiderBuySh12M(offset): The total number of shares purchased in 12-month increments, in millions of shares. The offset is in months, so an offset of one will show the 12-month total as it was one month ago.


InsiderSellSh1M(offset): The total number of shares sold in one-month increments, in millions of shares.

InsiderSellSh3M(offset): The total number of shares sold in three-month increments, in millions of shares. The offset is in months, so an offset of one will show the three-month total as it was one month ago.

InsiderSellSh6M(offset): The total number of shares sold in six-month increments, in millions of shares. The offset is in months, so an offset of one will show the six-month total as it was one month ago.

InsiderSellSh12M(offset): The total number of shares sold in 12-month increments, in millions of shares. The offset is in months, so an offset of one will show the 12-month total as it was one month ago.


InsiderBuyTran1M(offset): The total number of purchase transactions in the last month.

InsiderBuyTran3M(offset): The total number of purchase transactions in the last three months. The offset is in months, so an offset of one will show the three-month total as it was one month ago.

InsiderBuyTran6M(offset): The total number of purchase transactions in the last six months. The offset is in months, so an offset of one will show the six-month total as it was one month ago.

InsiderBuyTran12M(offset): The total number of purchase transactions in the last 12 months. The offset is in months, so an offset of one will show the 12-month total as it was one month ago.


InsiderSellTran1M(offset): The total number of sell transactions in the last month.

InsiderSellTran3M(offset): The total number of sell transactions in the last three months. The offset is in months, so an offset of one will show the three-month total as it was one month ago.

InsiderSellTran6M(offset): The total number of sell transactions in the last six months. The offset is in months, so an offset of one will show the six-month total as it was one month ago.

InsiderSellTran12M(offset): The total number of sell transactions in the last 12 months. The offset is in months, so an offset of one will show the 12-month total as it was one month ago.


InsiderUniqBuy1M(offset): The total number of unique inside buyers in the last month.

InsiderUniqBuy3M(offset): The total number of unique inside buyers in the last three months. The offset is in months, so an offset of one will show the three-month total as it was one month ago.

InsiderUniqSell1M(offset): The total number of unique inside sellers in the last month.

InsiderUniqSell3M(offset): The total number of unique inside sellers in the last three months. The offset is in months, so an offset of one will show the three-month total as it was one month ago.


Examples

To look for companies with more shares purchased than sold in the last six months, use:

InsNetShrPurch>0


To look for companies with more insider purchase transactions in the most recent month compared to the month prior, use:

InsiderBuyTran1M(0)>InsiderBuyTran1M(1)


To look for companies with fewer number of shares sold in the most recent month as compared to the 12-month average, use:

InsiderSellSh1M(0)<LoopAvg("InsiderSellSh1M(CTR)",12)


To look for companies that had at least 33% of the last three-month’s insider purchases happening within the most recent month, use:

InsiderBuySh1M(0)/InsiderBuySh3M(0)>.33
