Всего инсайдеров

Оценка инсайдерских настроений

Индекс настроений инсайдеров показывает, какие компании покупают корпоративные инсайдеры.

Это результат сложной многофакторной количественной модели, которая идентифицирует компании с самым высоким уровнем накопления инсайдерской информации. Модель оценки использует комбинацию чистого количества инсайдеров, купивших акции за предыдущие 90 дней, общего количества купленных акций в процентах от находящихся в обращении и общего количества акций, принадлежащих инсайдерам. Число варьируется от 0 до 100, причем более высокие цифры указывают на более высокий уровень накопления по сравнению с аналогами, а 50 — это среднее значение.

Частота обновлений: ежедневно

См. раздел «Выбор инсайдеров», в котором представлен список компаний с наибольшим накоплением инсайдеров.

Оценка настроений офицеров

Оценка настроений руководителей показывает, что компании покупаются руководителями корпораций.

По определению, корпоративные должностные лица являются корпоративными инсайдерами, но в отличие от некоторых других инсайдеров (10% акционеров и членов совета директоров), должностные лица работают в компании ежедневно и используют свои собственные деньги при торговле . (10% акционеров и членов совета директоров часто являются управляющими фондами, управляющими деньгами других людей.) Таким образом, инсайдерские сделки, совершаемые должностными лицами, гораздо более значимы, и к ним следует относиться соответствующим образом.

Как и оценка инсайдерских настроений, оценка настроений сотрудников является результатом сложной многофакторной количественной модели, которая идентифицирует компании с самым высоким уровнем накопления сотрудников.

Частота обновлений: ежедневно

См. раздел «Лучшие выборы инсайдеров», в котором представлен список компаний с самыми высокими инсайдерскими настроениями.

Ключевые инсайдерские показатели

На этой карточке показано место компании по различным инсайдерским показателям. Процентильный рейтинг показывает, как эта компания сравнивается с другими компаниями на рынках США. Более высокие рейтинги указывают на лучшие ситуации.

Например, общепринято, что инсайдерские покупки являются положительным показателем, поэтому компании с большим количеством инсайдерских покупок будут иметь более высокий рейтинг, чем компании с меньшим количеством инсайдерских покупок (или даже с меньшим количеством инсайдерских продаж).

Чистое количество инсайдерских покупок (рейтинг)

N/A

Чистое количество инсайдерских покупок — это общее количество инсайдерских покупок минус общее количество инсайдерских продаж за последние 90 дней. Здесь показан процентильный ранг (диапазон от 0 до 100%).

Процент акций, купленных инсайдерами (ранг)

N/A

Процент акций, купленных инсайдерами, — это общее количество акций, купленных инсайдерами, минус общее количество акций, проданных инсайдерами за последние 90 дней, разделенное на общее количество акций в обращении и умноженное на 100.

График инсайдерской торговли

Инсайдерские сделки (XOMA Royalty Corporation - Preferred Stock) показаны на следующей диаграмме. Инсайдеры — это должностные лица, директора или крупные инвесторы компании. В целом инсайдерам запрещено совершать сделки в своих компаниях на основе существенной, закрытой информации. Это не означает, что для них незаконно совершать какие-либо сделки в своих собственных компаниях. Однако они должны сообщать обо всех сделках в SEC через форму 4.

Список инсайдеров и показатели прибыльности

В этой таблице показан список известных инсайдеров, который создается автоматически на основе документов, раскрытых в SEC. Помимо имен, последней должности и указания директора, должностного лица или владельца 10% акций, мы предоставляем информацию о последних раскрытых активах. Кроме того, когда это возможно, мы предоставляем инсайдерам исторические результаты торговли. Исторические результаты торговли представляют собой средневзвешенное значение результатов фактических транзакций покупки на открытом рынке, совершенных инсайдером. Для получения дополнительной информации о том, как это рассчитывается, посмотрите этот вебинар на YouTube.
