Support vs Resistance Overview
| Concept | Meaning | Example |
|---|---|---|
| Support | Price floor (buy zone) | KO holding steady levels |
| Resistance | Price ceiling (sell zone) | MSFT near highs |
| Role Reversal | Old resistance becomes support | NVDA breakout |
1. Support: The Floor
Support is a price level where a stock tends to stop falling because buyers step in and increase demand.
- Institutional Buying: Large investors often place buy orders at these levels
- Psychology: Traders see the price as undervalued
Defensive stocks like Coca-Cola often show strong support levels where long-term investors accumulate shares.
2. Resistance: The Ceiling
Resistance is a level where a stock struggles to move higher as sellers begin taking profits.
- Profit Taking: Traders sell as price rises
- Psychological Levels: Round numbers like $100 or $500 act as barriers
Stocks like Microsoft often face resistance near all-time highs where selling pressure increases.
3. Role Reversal (The Flip)
One of the most powerful trading concepts is when resistance turns into support after a breakout.
- Breakout: Price moves above resistance
- Retest: Price comes back and holds that level as support
NVIDIA is a strong example of this pattern, where previous highs become new support levels during an uptrend.
Key Risks to Consider
- False Breakouts: Price may break a level and reverse quickly
- Fakeouts: Price may dip below support before bouncing
- Overprecision: Levels are zones, not exact lines
Trading Strategy Basics
- Buy near support when price shows signs of bouncing
- Place stop loss slightly below support
- Sell near resistance before price reaches the exact level
Final Verdict
- ✔ Support and resistance are essential trading tools
- ✔ Combining them with volume improves accuracy
- ✔ Always treat levels as zones, not exact numbers
