Media Sentiment Index
Comment les sources d'actualité font-elles évoluer leur sentiment de marché ? Cet indice mesure le biais éditorial sur — articles analysés par l'IA, issus de plus de 90 sources.
Methodology
Each article from our RSS feed network is analyzed by an advanced AI language model, which classifies it on a continuous sentiment scale from −1.0 (strongly bearish) to +1.0 (strongly bullish). Articles are grouped by source and ISO week. We compute the mean sentiment, standard deviation, and the proportion of bullish (> 0.15), bearish (< −0.15), and neutral articles per source per week. The divergence score measures how much sources disagree on a given market context.
