http://dbpedia.org/ontology/abstract A stock market bubble is a type of economiA stock market bubble is a type of economic bubble taking place in stock markets when market participants drive stock prices above their value in relation to some system of stock valuation. Behavioral finance theory attributes stock market bubbles to cognitive biases that lead to groupthink and herd behavior. Bubbles occur not only in real-world markets, with their inherent uncertainty and noise, but also in highly predictable experimental markets. In the laboratory, uncertainty is eliminated and calculating the expected returns should be a simple mathematical exercise, because participants are endowed with assets that are defined to have a finite lifespan and a known probability distribution of dividends.Other theoretical explanations of stock market bubbles have suggested that they are rational, intrinsic, and contagious.y are rational, intrinsic, and contagious. , فقاعة الأسهم المالية (بالإنجليزية: Stock Mفقاعة الأسهم المالية (بالإنجليزية: Stock Market Bubble)‏ هي نوع من أنواع الفقاعات الاقتصادية التي تحدث في أسواق الأسهم؛ إذ يدفع المشاركون في السوق أسعار للأسهم أعلى من قيمتها المعتمدة في نظام تقييم الأسهم. تعزو نظرية التمويل السلوكي حدوث فقاعة في سوق الأسهم إلى التحيزات المعرفية التي تؤدي إلى التفكير الجماعي وسلوك القطيع. لا تحدث الفقاعات فقط في الأسواق الفعلية التي تتميز بعدم اليقين والفوضى المتأصلة فيها، ولكن أيضًا في الأسواق التجريبية التي يمكن التنبؤ بها بدرجة عالية. في الأسواق التجريبية، يُستبعد عدم اليقين وينبغي أن يكون حساب العوائد المتوقعة مسألةً رياضية بسيطة، إذ يُمنح المشاركون أصولًا معرّفة تتمتع بعمر محدد وتوزيع محتمل للأرباح. لقد أوضحت التفسيرات النظرية الأخرى لفقاعات سوق الأسهم أنها منطقية وجوهرية ومُعدية.ات سوق الأسهم أنها منطقية وجوهرية ومُعدية. , Una burbuja del mercado de valores es un tUna burbuja del mercado de valores es un tipo de burbuja económica que tiene lugar en los mercados de valores cuando los participantes del mismo llevan los precios de las acciones por encima de su valor en relación con el sistema de valoración de acciones. Las teorías sobre el atribuyen las burbujas del mercado de valores a sesgos cognitivos que desembocan en pensamiento colectivo y comportamiento de masas. Estas burbujas no solamente ocurren en mercados reales con su intrínseca incertidumbre, pues también tienen lugar en mercados altamente predecibles y experimentales.​En un entorno controlado, la incertidumbre se debería eliminar y el cálculo del retorno esperado debería suponer un ejercicio matemático simple, pues los participantes están dotados con activos que definidos para tener una vida útil limitada y una probabilidad conocida de distribución de dividendos. Otras explicaciones teóricas de las burbujas del mercado de valores sugieren que se trata de un fenómeno racional,​ intrínseco​y contagioso. ​meno racional,​ intrínseco​y contagioso. ​
