Skor Sentimen Orang Dalam
Skor Sentimen Orang Dalam mengidentifikasi perusahaan yang dibeli oleh orang dalam korporat.
Ini adalah hasil dari model kuantitatif multifaktor yang canggih yang mengidentifikasi perusahaan dengan tingkat akumulasi internal tertinggi. Model penilaian ini menggunakan kombinasi dari jumlah bersih orang dalam yang membeli dalam 90 hari sebelumnya, total saham yang dibeli sebagai persentase dari jumlah saham yang beredar, dan total saham yang dimiliki oleh orang dalam. Angka tersebut berkisar dari 0 hingga 100, dengan angka yang lebih tinggi menunjukkan tingkat akumulasi yang lebih tinggi dibandingkan dengan perusahaan sejenis, dan 50 adalah rata-rata.
Frekuensi Pembaruan: Setiap Hari
Skor Sentimen Petugas
Skor Sentimen Pejabat menemukan perusahaan yang dibeli oleh Pejabat Korporat.
Menurut definisi, Pejabat Korporasi adalah Orang Dalam Korporasi, tetapi tidak seperti beberapa Orang Dalam lainnya (Pemegang Saham 10% dan Anggota Dewan), Pejabat bekerja untuk perusahaan setiap hari, dan mereka menggunakan uang mereka sendiri saat bertransaksi . (Pemegang Saham 10% dan Anggota Dewan seringkali adalah manajer dana yang mengelola uang orang lain.) Dengan demikian, transaksi orang dalam yang dilakukan oleh Pejabat jauh lebih signifikan dan harus ditangani dengan tepat.
Seperti Skor Sentimen Internal, Skor Sentimen Pejabat adalah hasil dari model kuantitatif multi-faktor yang canggih yang mengidentifikasi perusahaan dengan tingkat akumulasi pejabat tertinggi.
Frekuensi Pembaruan: Setiap Hari

Grafik Perdagangan Orang Dalam
Grafik berikut menunjukkan Ambarella, Inc. transaksi orang dalam. Orang dalam adalah pejabat, direktur, atau investor signifikan dalam suatu perusahaan.

Ini tidak berarti bahwa mereka dilarang melakukan transaksi apa pun di perusahaan mereka sendiri. Namun, mereka wajib melaporkan semua transaksi kepada SEC melalui Formulir 4.
Daftar Orang Dalam dan Metrik Profitabilitas
Tabel ini menampilkan daftar orang dalam yang diketahui, dan dibuat secara otomatis dari pengajuan yang diungkapkan kepada SEC. Selain nama, jabatan terbaru, dan sebutan direktur, pejabat, atau pemilik 10%, kami memberikan kepemilikan terbaru yang diungkapkan. Selain itu, jika memungkinkan, kami memberikan kinerja perdagangan historis untuk orang dalam tersebut. Kinerja perdagangan historis adalah rata-rata tertimbang dari kinerja transaksi pembelian pasar terbuka aktual yang dilakukan oleh orang dalam tersebut.
