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.

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.
