परिचय

यह पृष्ठ James Chao के ज्ञात इनसाइडर व्यापार इतिहास का व्यापक विश्लेषण प्रदान करता है। इनसाइडर किसी कंपनी के अधिकारी, निदेशक या महत्वपूर्ण निवेशक होते हैं। इनसाइडर के लिए विशिष्ट, गैर-सार्वजनिक जानकारी के आधार पर अपनी कंपनियों में व्यापार करना गैरकानूनी है। इसका मतलब यह नहीं है कि उनके लिए अपनी कंपनियों में कोई भी व्यापार करना गैरकानूनी है। हालाँकि, उन्हें फॉर्म 4 के माध्यम से SEC को सभी ट्रेड्स की रिपोर्ट करनी होगी। इन प्रतिबंधों के बावजूद, अकादमिक शोध से पता चलता है कि इनसाइडर - सामान्य तौर पर - अपनी कंपनियों में बाजार से बेहतर प्रदर्शन करते हैं।

औसत व्यापार लाभप्रदता

औसत ट्रेड लाभप्रदता पिछले तीन वर्षों में इनसाइडर द्वारा की गई सभी खुले बाजार खरीद का औसत रिटर्न है। इसकी गणना करने के लिए, हम 10b5-1 ट्रेडिंग योजना के हिस्से के रूप में चिह्नित सभी ट्रेडों को छोड़कर, इनसाइडर द्वारा की गई प्रत्येक खुले बाजार, अनियोजित खरीदारी की जांच करते हैं। फिर हम 3, 6 और 12 महीनों में उन ट्रेडों के औसत प्रदर्शन की गणना करते हैं, प्रत्येक ट्रेड के लिए अंतिम प्रदर्शन मीट्रिक तैयार करने के लिए उनमें से प्रत्येक अवधि का औसत निकालते हैं। अंत में, हम इनसाइडर के लिए प्रदर्शन मीट्रिक की गणना करने के लिए सभी प्रदर्शन मीट्रिक का औसत निकालते हैं। इस सूची में केवल उन इनसाइडर को शामिल किया गया है जिन्होंने पिछले दो वर्षों में कम से कम तीन ट्रेड किए हैं।

यदि इस इनसाइडर ट्रेड की लाभप्रदता "N/A" है, तो इनसाइडर ने या तो पिछले तीन वर्षों में कोई खुले बाजार में खरीदारी नहीं की है, या उनके द्वारा किए गए व्यापार एक विश्वसनीय प्रदर्शन मीट्रिक की गणना करने के लिए बहुत हाल के हैं।

SEC फाइलिंग से संकेत मिलता है कि James Chao ने निम्नलिखित कंपनियों में होल्डिंग्स या ट्रेड्स की सूचना दी है:

प्रतिभूति	टाइटल	नवीनतम रिपोर्ट की गई होल्डिंग्स

US:WLKP / Westlake Chemical Partners LP - Limited Partnership	Senior Chairman, Director	0

चार्ट को कैसे समझे

निम्नलिखित चार्ट James Chao द्वारा किए गए प्रत्येक खुले-बाज़ार, गैर-योजनाबद्ध व्यापार के बाद प्रतिभूतियों के स्टॉक प्रदर्शन को दर्शाते हैं। गैर-योजनाबद्ध व्यापार वे व्यापार हैं जो 10b5-1 ट्रेडिंग योजना के हिस्से के रूप में नहीं किए गए थे। स्टॉक प्रदर्शन को शेयर मूल्य में संचयी प्रतिशत परिवर्तन के रूप में चार्ट किया गया है। उदाहरण के लिए, यदि कोई इनसाइडर व्यापार 1 जनवरी, 2019 को किया गया था, तो चार्ट आज तक प्रतिभूति में दैनिक प्रतिशत परिवर्तन दिखाएगा। यदि इस दौरान शेयर की कीमत $10 से $15 तक जाती है, तो शेयर की कीमत में संचयी प्रतिशत परिवर्तन 50% होगा। $10 से $20 तक की कीमत में परिवर्तन 100% होगा, और $10 से $5 की कीमत में परिवर्तन -50% होगा।

अंततः, हम यह निर्धारित करने का प्रयास कर रहे हैं कि इनसाइडर के व्यापार शेयर की कीमत में अतिरिक्त रिटर्न (सकारात्मक या नकारात्मक) से कितनी निकटता से संबंधित हैं, यह देखने के लिए कि क्या इनसाइडर, इनसाइडर जानकारी से लाभ के लिए अपने व्यापार का समय निर्धारित कर रहे हैं। उस स्थिति पर विचार करें जहां कोई इनसाइडर ऐसा कर रहा था। इस स्थिति में, हम या तो (a) खरीदारी के बाद सकारात्मक रिटर्न, या (a) बिक्री के बाद नकारात्मक रिटर्न की उम्मीद करेंगे। (a) के मामले में, खरीद चार्ट ऊपर की ओर झुके हुए वक्रों की एक श्रृंखला दिखाएगा, जो प्रत्येक खरीद लेनदेन के बाद सकारात्मक रिटर्न का संकेत देगा। (a) के मामले में, बिक्री चार्ट नीचे की ओर झुके हुए वक्रों की एक श्रृंखला दिखाएगा, जो प्रत्येक बिक्री लेनदेन के बाद नकारात्मक रिटर्न का संकेत देगा।

हालाँकि, केवल यह निष्कर्ष निकालने के लिए पर्याप्त नहीं है। यदि, उदाहरण के लिए, कंपनी का शेयर मूल्य कई वर्षों से गैर-चक्रीय चढ़ाई में था, तो हम उम्मीद करेंगे कि खरीद के बाद के सभी प्लॉट ऊपर की ओर झुके हुए होंगे। इसी तरह, कई वर्षों में गैर-चक्रीय गिरावट के परिणामस्वरूप व्यापार के बाद के प्लॉट नीचे की ओर झुकेंगे। इनमें से कोई भी चार्ट इनसाइडर व्यापार गतिविधि का सुझाव नहीं देगा।

सबसे मजबूत संकेतक वह स्थिति होगी जहां शेयर की कीमत बेहद चक्रीय थी, और खरीद चार्ट में सकारात्मक संकेत और बिक्री चार्ट पर नकारात्मक प्लॉट दोनों थे। यह स्थिति एक इनसाइडर के लिए अत्यधिक संकेत देने वाली होगी जो अपने वित्तीय लाभ के लिए ट्रेड्स का समय निर्धारित कर रहा था।
