कुशल बाजार परिकल्पना (Efficient Market Hypothesis – EMH) वित्त और शेयर बाजार से जुड़ा एक सिद्धांत है। इसके अनुसार शेयर बाजार में उपलब्ध सारी महत्वपूर्ण जानकारी पहले से ही शेयर की कीमतों में शामिल होती है। इसलिए किसी निवेशक के लिए लगातार बाजार से ज्यादा रिटर्न कमाना आसान नहीं माना जाता।
इस सिद्धांत को मुख्य रूप से तीन भागों में बाँटा जाता है – weak form, semi-strong form और strong form efficiency। EMH के समर्थकों का मानना है कि शेयर की कीमतें बहुत तेजी से नई जानकारी को reflect करती हैं।
हालांकि कई निवेशक और विशेषज्ञ मानते हैं कि व्यवहारिक गलतियों, भावनाओं और market inefficiencies की वजह से कभी-कभी बाजार को outperform करना संभव हो सकता है।
