Fundamentals
What is a momentum stock?
A momentum stock is not simply a stock that went up today. It is a liquid stock that is outperforming the market, outperforming its peers, trending above key moving averages, attracting above-normal volume, and staying near recent highs without becoming too extended.
The five traits
| Trait | The question it answers |
|---|---|
| Relative strength | Is this stock beating the market? |
| Trend quality | Is it in a real, structured uptrend? |
| Volume confirmation | Is money actually moving into it? |
| Catalyst / fundamentals | Is there a reason this can continue? |
| Risk / entry quality | Is it still tradable, or already extended? |
Each trait carries a point weight in the Momentum Score, and each one maps to specific fields inside a stock screener. That is the entire method: turn a vague trait into a filter, then turn a set of filters into a repeatable recipe.
1. Relative strength
Relative strength compares a stock's return to a benchmark such as SPY or QQQ, and to the stock's own peer group. A stock rising 8% in a quarter when the index rose 10% is not a momentum stock — it is a laggard in an uptrend.
| Measure | Strong reading |
|---|---|
| 3-month performance | Better than SPY or QQQ |
| 6-month performance | Strongly positive |
| 12-month performance | Strongly positive |
| Relative strength line | Rising or near highs |
| Industry group | Also strong |
Leaders usually show relative strength before they become obvious. That is the whole reason to measure it rather than eyeball a chart.
2. Trend quality
Trend quality separates a stock in a durable uptrend from one bouncing inside a downtrend. The standard checks:
- Price above the 50-day simple moving average
- Price above the 200-day simple moving average
- 50-day above the 200-day
- Within roughly 15–20% of the 52-week high
- Chart structure of higher highs and higher lows
A stock below its 200-day may still bounce. It is usually not a clean momentum leader.
3. Volume confirmation
Price without volume is unreliable. Volume confirmation asks whether real demand is behind the move: relative volume above 1.5–2.0, breakouts occurring on above-average volume, up days showing heavier volume than down days, and enough dollar volume that you are not the liquidity.
4. Catalyst and fundamentals
This is what keeps the process from being purely technical. Earnings growth, revenue growth, a guidance raise, a product or news event, or a sector tailwind all give a reason the repricing can continue. A strong chart with a business reason behind it is a different proposition from a random spike.
5. Risk and entry quality
A stock can be a great company and a terrible entry. The warning signs:
| Risk | Why it matters |
|---|---|
| Far above the 10/20/50-day averages | Late entry risk |
| Illiquid trading | Slippage and manipulation risk |
| Huge gap with no base | Chase risk |
| Wide ATR | A sensible stop may be too far away |
| Weak market environment | Momentum reverses quickly in a downtrend |
Momentum versus hype
The difference is confirmation. Hype is price movement with thin volume, no earnings support, no sector participation and no defined risk level. Momentum is price movement with all four. The score exists to force that distinction before a name reaches your watchlist.
Where momentum comes from
The effect is well documented. Jegadeesh and Titman's 1993 paper in The Journal of Finance found that buying past winners and selling past losers produced positive returns over 3-to-12-month holding periods. Index providers such as MSCI still build momentum indexes on high price momentum with liquidity and turnover controls. None of that means any individual momentum trade works — crowded momentum unwinds violently. Measure it, and respect the risk side.
