Market Sentiment and Momentum
Prices reflect what investors feel about the future, not only today's facts. That collective mood is sentiment.
Why this matters for beginners
Sentiment explains why prices overshoot in both directions. This is general education, not personal advice.
Main explanation
When investors feel optimistic, they pay more for the same expected profits. When fearful, they pay less.
Momentum is the tendency for rising prices to attract more buyers, and falling prices to attract more sellers, for a while.
Momentum can run further than fundamentals justify, then reverse sharply when the mood turns.
Headlines, social media and fear of missing out all amplify sentiment in the short run.
Example using a real company
Many technology shares rose far in 2020 and 2021 on optimism, then fell steeply in 2022 when sentiment soured, even though most businesses kept operating.
- →Same profit, different mood: 20 times earnings when optimistic, 12 times when fearful.
- →A share up 40 percent in a month attracts trend followers, then drops 25 percent when buying dries up.
