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.

Metrik Utama Orang Dalam
Kartu ini menunjukkan peringkat perusahaan berdasarkan berbagai metrik internal. Peringkat persentil menunjukkan bagaimana perusahaan ini dibandingkan dengan perusahaan lain di pasar AS. Peringkat yang lebih tinggi menunjukkan situasi yang lebih baik.
Sebagai contoh, secara umum diterima bahwa pembelian oleh orang dalam perusahaan adalah indikator positif, sehingga perusahaan dengan lebih banyak pembelian oleh orang dalam akan mendapat peringkat lebih tinggi daripada perusahaan dengan lebih sedikit pembelian oleh orang dalam (atau bahkan penjualan oleh orang dalam).
Jumlah Bersih Pembelian oleh Orang Dalam (Peringkat)
0 ( )
5797 out of 11323Jumlah Bersih Pembelian oleh Orang Dalam adalah total jumlah orang dalam yang membeli dikurangi total jumlah orang dalam yang menjual dalam 90 hari terakhir. Peringkat persentil ditunjukkan di sini (kisaran dari 0 hingga 100%).
Persentase Saham yang Dibeli oleh Orang Dalam (Peringkat)
0.000 %( )
5960 out of 11224Persentase Saham yang Dibeli oleh Orang Dalam adalah total jumlah saham yang dibeli oleh orang dalam dikurangi total jumlah saham yang dijual oleh orang dalam dalam 90 hari terakhir, dibagi dengan total jumlah saham yang beredar dan dikalikan dengan 100.
Grafik Perdagangan Orang Dalam
Grafik berikut menunjukkan Westlake Corporation transaksi orang dalam. Orang dalam adalah pejabat, direktur, atau investor signifikan dalam suatu perusahaan. Secara umum, melakukan transaksi di perusahaan mereka berdasarkan informasi material yang belum dipublikasikan adalah ilegal bagi orang dalam. 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.
