The basic idea
Momentum is the tendency of a stock that has been rising to keep rising, and of one that has been falling to keep falling — at least over a given window. It is not a law of nature; it is an empirical pattern observed in many markets over many periods. Lucex reports momentum as context, not as a predictor of what will happen next.
How Lucex measures it
Lucex looks at the stock's performance relative to its own recent history: how it has moved over the last 20–60 sessions, whether it is above or below its 50-day and 200-day moving averages, and where it sits within its 52-week range. These are descriptive facts about the price chart, not recommendations.
Why momentum can reverse
Earnings surprises, macro data, regulatory news, or a shift in market sentiment can break a momentum trend abruptly. Stocks with high upward momentum can fall hard if expectations aren't met. This is why Lucex pairs momentum data with fundamentals and analyst consensus — to give a fuller picture rather than one signal in isolation.
What momentum cannot tell you
Past price movement does not guarantee future price movement. A stock that has risen 40% in six months may continue to rise, plateau, or reverse — momentum alone cannot distinguish which. Use it as one dimension of context, not a decision engine.
