Skor Sentimen Orang Dalam

Skor Sentimen Orang Dalam mendapati syarikat dibeli oleh orang dalam korporat.

Ia adalah hasil daripada model kuantitatif berbilang faktor yang canggih yang mengenal pasti syarikat dengan tahap pengumpulan orang dalam yang paling tinggi. Model pemarkahan menggunakan gabungan bilangan bersih orang dalam yang membeli 90 hari sebelumnya, jumlah saham yang dibeli sebagai peratusan saham beredar, dan jumlah saham yang dimiliki oleh orang dalam. Nombor ini berjulat dari 0 hingga 100, dengan nombor yang lebih tinggi menunjukkan tahap pengumpulan yang lebih tinggi kepada rakannya, dan 50 adalah purata.

Skor Sentimen Pegawai

Skor Sentimen Pegawai mendapati syarikat dibeli oleh Pegawai Korporat.

Mengikut definisi Pegawai Korporat ialah Orang Dalam Korporat, tetapi tidak seperti beberapa Orang Dalam yang lain (10% Pemegang Saham dan Ahli Lembaga), Pegawai bekerja untuk syarikat tersebut setiap hari, dan mereka menggunakan wang mereka sendiri semasa berdagang . (10% Pemegang Saham dan Ahli Lembaga Pengarah selalunya pengurus dana yang menguruskan wang orang lain.) Oleh itu, dagangan orang dalam yang dibuat oleh Pegawai adalah lebih penting dan harus dilayan dengan sewajarnya.

Seperti Skor Sentimen Orang Dalam, Skor Sentimen Pegawai adalah hasil daripada model kuantitatif berbilang faktor yang canggih yang mengenal pasti syarikat yang mempunyai tahap pengumpulan pegawai tertinggi.

Metrik Orang Dalam Utama

Kad ini menunjukkan bagaimana kedudukan syarikat mengikut pelbagai metrik orang dalam. Kedudukan persentil menunjukkan cara syarikat ini dibandingkan dengan syarikat lain di pasaran AS. Kedudukan yang lebih tinggi menunjukkan keadaan yang lebih baik.

Sebagai contoh, adalah diterima umum bahawa pembelian orang dalam ialah penunjuk positif, jadi syarikat yang mempunyai lebih banyak pembelian orang dalam akan mendapat kedudukan lebih tinggi daripada syarikat yang kurang pembelian orang dalam (atau malah jualan orang dalam).

Bilangan Bersih Pembelian Orang Dalam (Kedudukan)

N/A

Bilangan Bersih Pembelian Orang Dalam ialah jumlah bilangan orang dalam yang membeli tolak jumlah orang dalam yang menjual dalam tempoh 90 hari terakhir. Kedudukan persentil ditunjukkan di sini (julat dari 0 hingga 100%).

Peratusan Saham Beredar yang Dibeli oleh Orang Dalam (Kedudukan)

N/A

Peratusan Saham Beredar yang Dibeli oleh Orang Dalam ialah jumlah bilangan saham yang dibeli oleh orang dalam tolak jumlah bilangan saham yang dijual oleh orang dalam dalam tempoh 90 hari terakhir, dibahagikan dengan jumlah saham beredar dan didarab dengan 100.

Carta Dagangan Dalaman

XOMA Royalty Corporation - Preferred Stock dagangan dalaman ditunjukkan dalam carta berikut. Orang dalam ialah pegawai, pengarah atau pelabur penting dalam syarikat. Secara umumnya adalah menyalahi undang-undang bagi orang dalam untuk membuat perdagangan dalam syarikat mereka berdasarkan maklumat material dan bukan awam. Ini tidak bermakna haram untuk mereka membuat sebarang perdagangan dalam syarikat mereka sendiri. Walau bagaimanapun, mereka mesti melaporkan semua dagangan kepada SEC melalui Borang 4.

Senarai Orang Dalam dan Metrik Keberuntungan
