How this comparison is scored
The Algovestiq AIQ Score composites four factors — Quality, Value, Momentum and Risk, each carrying a fixed weight. Sentiment is reported separately as SentimentPulse and is not folded into the composite. Scores refresh every trading day, and this page regenerates from the latest snapshot rather than being written once.
The verdict names a leader, states how broadly six independent evidence groups agree, and rates how durable that conclusion is given the score gap, its recent trajectory and the current signal state on both names.
