इनसाइडर सेंटीमेंट स्कोर

इनसाइडर सेंटीमेंट स्कोर उन कंपनियों का पता लगाता है जिन्हें कॉर्पोरेट इनसाइडर द्वारा खरीदा जा रहा है।

यह एक परिष्कृत, बहु-कारक मात्रात्मक मॉडल का परिणाम है जो इनसाइडर संचय के उच्चतम स्तर वाली कंपनियों की पहचान करता है। स्कोरिंग मॉडल पिछले 90 दिनों में खरीदने वाले इनसाइडर की शुद्ध संख्या, फ्लोट के प्रतिशत के रूप में खरीदे गए कुल शेयर और इनसाइडर के स्वामित्व वाले कुल शेयरों के संयोजन का उपयोग करता है। संख्या 0 से 100 तक होती है, उच्च संख्याएं अपने प्रतिद्वंदिओ के लिए संचय के उच्च स्तर का संकेत देती हैं, और 50 औसत है।

ऑफिसर सेंटीमेंट स्कोर

ऑफिसर सेंटीमेंट स्कोर से पता चलता है कि कंपनियों को कॉर्पोरेट ऑफिसर द्वारा खरीदा जा रहा है।

परिभाषा के अनुसार कॉर्पोरेट ऑफिसर कॉर्पोरेट इनसाइडर्स होते हैं, लेकिन कुछ अन्य इनसाइडर्स (10% शेयरधारक और बोर्ड सदस्य) के विपरीत, ऑफिसर कंपनी के लिए दैनिक आधार पर काम करते हैं, और व्यापार करते समय वे अपने स्वयं के पैसे का उपयोग करते हैं। (10% शेयरधारक और बोर्ड सदस्य अक्सर अन्य लोगों के पैसे का प्रबंधन करने वाले फंड मैनेजर होते हैं।) इस प्रकार, ऑफिसर द्वारा किए गए इनसाइडर व्यापार बहुत अधिक महत्वपूर्ण होते हैं और उनके साथ उचित व्यवहार किया जाना चाहिए।

इनसाइडर सेंटीमेंट स्कोर की तरह, ऑफिसर सेंटीमेंट स्कोर एक परिष्कृत, बहु-कारक मात्रात्मक मॉडल का परिणाम है जो उच्चतम स्तर के ऑफिसर संचय वाली कंपनियों की पहचान करता है।

मुख्य इनसाइडर मेट्रिक्स

यह कार्ड दिखाता है कि कंपनी विभिन्न इनसाइडर मेट्रिक्स के साथ कैसे रैंक करती है। प्रतिशतक रैंक से पता चलता है कि यह कंपनी अमेरिकी बाज़ारों में अन्य कंपनियों से कैसे तुलना करती है। ऊंची रैंकिंग बेहतर स्थितियों का संकेत है।

उदाहरण के लिए, यह आम तौर पर स्वीकार किया जाता है कि इनसाइडर खरीदारी एक सकारात्मक संकेतक है, इसलिए अधिक इनसाइडर खरीदारी वाली कंपनियां कम इनसाइडर खरीदारी (या यहां तक कि इनसाइडर बिक्री) वाली कंपनियों की तुलना में उच्च रैंक पर होंगी।

खरीदने वाले इनसाइडर की शुद्ध संख्या (रैंक)

-5 ( )

11048 out of 11323

इनसाइडर ख़रीदारी की कुल संख्या, पिछले 90 दिनों में बेचने वाले इनसाइडर की कुल संख्या को घटाकर ख़रीदने वाले इनसाइडर की कुल संख्या है। प्रतिशतक रैंक यहां दिखाई गई है (0 से 100% तक)।

इनसाइडर द्वारा खरीदे गए फ़्लोट का प्रतिशत (रैंक)

-0.167 %( )

10721 out of 11244

इनसाइडर द्वारा खरीदे गए फ्लोट का प्रतिशत इनसाइडर द्वारा खरीदे गए शेयरों की कुल संख्या है, जिसमें पिछले 90 दिनों में इनसाइडर द्वारा बेचे गए शेयरों की कुल संख्या को घटाकर, कुल फ्लोट से विभाजित किया जाता है और 100 से गुणा किया जाता है।

इनसाइडर ट्रेडिंग चार्ट

Monolithic Power Systems, Inc. इनसाइडर व्यापार निम्नलिखित चार्ट में दिखाए गए हैं। इनसाइडर किसी कंपनी के ऑफिसर, निदेशक या महत्वपूर्ण निवेशक होते हैं। सामान्य तौर पर, इनसाइडर के लिए सामग्री, गैर-सार्वजनिक जानकारी के आधार पर अपनी कंपनियों में व्यापार करना आम तौर पर अवैध 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 ट्रेडों की रिपोर्ट करनी होगी।

इनसाइडर रोस्टर और प्रॉफिटेबिलिटी मेट्रिक्स

यह तालिका ज्ञात इनसाइडर की सूची दिखाती है, और SEC को बताई गई फाइलिंग से स्वचालित रूप से उत्पन्न होती है। नामों, सबसे हालिया शीर्षक, और निदेशक, ऑफिसर, या 10% मालिक पदनाम के अलावा, हम नवीनतम प्रकट होल्डिंग्स प्रदान करते हैं। इसके अतिरिक्त, जब भी संभव हो हम इनसाइडर के लिए ऐतिहासिक व्यापार प्रदर्शन प्रदान करते हैं। ऐतिहासिक व्यापार प्रदर्शन इनसाइडर द्वारा किए गए वास्तविक खुले बाजार खरीद लेनदेन के प्रदर्शन का एक भारित औसत है। इसकी गणना कैसे की जाती है, इसके बारे में अधिक जानकारी के लिए, यह YouTube वेबिनार देखें।
