Important Disclaimer First
For long-term index fund investors (which is what we recommend), chart reading is largely unnecessary. You buy regularly regardless of price (dollar-cost averaging) and hold for decades. Charts matter more for individual stock investors and traders.
That said, understanding charts helps you interpret financial news and make sense of market movements without panicking.
Chart Types
- Line chart: Simplest. Shows closing price over time as a single line. Good for seeing the overall trend at a glance.
- Candlestick chart: Shows open, high, low, and close for each time period. Green/white candle = price went up that day. Red/black = price went down. The "body" shows open-to-close range, "wicks" show the high and low.
- Bar chart: Similar info to candlesticks but less visual. Vertical line shows range, horizontal ticks show open (left) and close (right).
Most investors use candlestick charts because they show the most information in a compact visual format.
Key Concepts
Trend
The general direction of price over time. Higher highs and higher lows = uptrend. Lower highs and lower lows = downtrend. Flat = sideways/range-bound.
Support and Resistance
- Support: A price level where buyers tend to step in, preventing further decline. Think of it as a "floor." If a stock bounces off $50 three times, $50 is support.
- Resistance: A price level where sellers tend to appear, preventing further rise. A "ceiling." If a stock fails to break above $100 multiple times, $100 is resistance.
Volume
Number of shares traded. High volume on a price move confirms conviction. A breakout to new highs on heavy volume is more meaningful than one on low volume. Low volume suggests the move might not sustain.
Moving Averages
- 50-day moving average (50 MA): Average closing price of last 50 days. Shows medium-term trend. Price above 50 MA = generally bullish.
- 200-day moving average (200 MA): Average of last 200 days. Shows long-term trend. Many institutions use this as a bull/bear market indicator.
- "Golden cross": 50 MA crosses above 200 MA. Historically bullish signal.
- "Death cross": 50 MA crosses below 200 MA. Historically bearish signal.
Where to View Charts (Free)
- Yahoo Finance: Basic charts with common indicators. Good enough for most investors.

- Google Finance: Simplest view. Price and basic comparison tools.
- Your brokerage: Fidelity, Schwab, and Vanguard all provide built-in charting tools.
What Charts Cannot Tell You
- Whether a company will beat earnings next quarter
- Whether a new competitor will disrupt the business
- What interest rates will do next month
- Whether a stock is overvalued or undervalued (that requires fundamental analysis)
Charts show what happened. They don't predict what will happen. Use them as one input among many - not as a decision-making system on their own.
The Only Chart That Matters for Most People
The S&P 500 chart over 50+ years. It goes up. It has crashes (2001, 2008, 2020, 2022). It always recovers. If you zoom out far enough, every crash looks like a blip. That's why we recommend long-term index investing over chart-based trading.
