Robert R Anderson - Insider Trading Tracker

Pendahuluan

Halaman ini memberikan analisis komprehensif tentang sejarah perdagangan orang dalam yang diketahui dari Robert R Anderson. Orang dalam adalah pejabat, direktur, atau investor signifikan dalam suatu perusahaan. Adalah ilegal bagi orang dalam untuk melakukan perdagangan di perusahaan mereka berdasarkan informasi spesifik yang tidak dipublikasikan. Ini tidak berarti bahwa mereka dilarang melakukan perdagangan apa pun di perusahaan mereka sendiri. Namun, mereka harus melaporkan semua perdagangan kepada SEC melalui Formulir 4. Terlepas dari pembatasan ini, penelitian akademis menunjukkan bahwa orang dalam - secara umum - cenderung mengungguli pasar di perusahaan mereka sendiri.

Rata-rata Profitabilitas Perdagangan

Profitabilitas perdagangan rata-rata adalah pengembalian rata-rata dari semua pembelian pasar terbuka yang dilakukan oleh orang dalam dalam tiga tahun terakhir. Untuk menghitung ini, kami memeriksa setiap pembelian pasar terbuka yang tidak direncanakan yang dilakukan oleh orang dalam, tidak termasuk semua perdagangan yang ditandai sebagai bagian dari rencana perdagangan 10b5-1. Kami kemudian menghitung kinerja rata-rata dari perdagangan tersebut selama 3, 6, dan 12 bulan, dengan merata-ratakan setiap durasi tersebut untuk menghasilkan metrik kinerja akhir untuk setiap perdagangan. Terakhir, kami merata-ratakan semua metrik kinerja untuk menghitung metrik kinerja untuk orang dalam. Daftar ini hanya mencakup orang dalam yang telah melakukan setidaknya tiga perdagangan dalam dua tahun terakhir.

Jika profitabilitas perdagangan orang dalam ini adalah "N/A", maka orang dalam tersebut belum melakukan pembelian di pasar terbuka dalam tiga tahun terakhir, atau perdagangan yang mereka lakukan terlalu baru untuk menghitung metrik kinerja yang andal.

Cara Membaca Grafik

Grafik berikut menunjukkan kinerja saham sekuritas setelah setiap perdagangan pasar terbuka yang tidak direncanakan yang dilakukan oleh Robert R Anderson. Perdagangan yang tidak direncanakan adalah perdagangan yang tidak dilakukan sebagai bagian dari rencana perdagangan 10b5-1. Kinerja saham digambarkan sebagai perubahan persentase kumulatif dalam harga saham. Misalnya, jika perdagangan orang dalam dilakukan pada 1 Januari 2019, grafik akan menunjukkan perubahan persentase harian sekuritas hingga saat ini. Jika harga saham naik dari $10 menjadi $15 selama periode ini, perubahan persentase kumulatif dalam harga saham akan menjadi 50%. Perubahan harga dari $10 menjadi $20 akan menjadi 100%, dan perubahan harga dari $10 menjadi $5 akan menjadi -50%.

Pada akhirnya, kita mencoba menentukan seberapa erat korelasi perdagangan orang dalam dengan pengembalian berlebih (positif atau negatif) pada harga saham untuk melihat apakah orang dalam tersebut mengatur waktu perdagangannya untuk mendapatkan keuntungan dari informasi orang dalam. Pertimbangkan situasi di mana orang dalam melakukan hal ini. Dalam situasi ini, kita akan mengharapkan (a) pengembalian positif setelah pembelian, atau (b) pengembalian negatif setelah penjualan. Dalam kasus (a), grafik PEMBELIAN akan menunjukkan serangkaian kurva yang miring ke atas, menunjukkan pengembalian positif setelah setiap transaksi pembelian. Dalam kasus (b), grafik PENJUALAN akan menunjukkan serangkaian kurva yang miring ke bawah, menunjukkan pengembalian negatif setelah setiap transaksi penjualan.

Namun, ini saja tidak cukup untuk menarik kesimpulan. Jika, misalnya, harga saham perusahaan berada dalam tren kenaikan non-siklikal selama bertahun-tahun, maka kita akan mengharapkan semua plot pasca-pembelian memiliki kemiringan ke atas. Demikian pula, penurunan non-siklikal selama bertahun-tahun akan menghasilkan plot pasca-perdagangan dengan kemiringan ke bawah. Tak satu pun dari grafik ini akan menunjukkan aktivitas perdagangan orang dalam.

Indikator terkuat adalah situasi di mana harga saham sangat siklikal, dan terdapat sinyal positif pada grafik PEMBELIAN dan plot negatif pada grafik PENJUALAN. Situasi ini akan sangat menunjukkan adanya orang dalam yang mengatur waktu perdagangan untuk keuntungan finansial mereka.
