Can You Guess a Stock Just by Its Chart? — Chart Analysis Basics

"This chart pattern is a bullish signal!" Ever heard something like that? If you've dabbled in stock investing, chart analysis is unavoidable. But when you actually look at a chart... it's all squiggly lines, right?

Today we'll break down chart analysis basics in plain language. By the end, you'll at least be able to say "Oh, that means this" when looking at a stock chart.

Types of Stock Charts

Different stock chart types - line chart and candlestick chart

There are three main types:

1. Line Chart — The simplest. Connects daily closing prices with a line. Great for seeing the overall trend at a glance.

2. Candlestick Chart — The most widely used. Shows the open, close, high, and low for each period. Green/red candles show whether the price went up or down.

3. Bar Chart — Similar to candlesticks but uses bars instead. More common in U.S. markets.

How to Read a Candlestick Chart

The candlestick chart is the absolute fundamental. Each candle contains this information:

Body — The range between open and close. For a green (bullish) candle, the bottom is the open and the top is the close. For red (bearish), it's reversed.
Upper shadow (wick) — Shows the session high. "The price went up here but came back down."
Lower shadow — Shows the session low. "It dropped here but recovered."

Long shadows? → High volatility. A long upper shadow means "strong selling pressure," while a long lower shadow means "buyers stepped in."

5 Famous Chart Patterns

Chart pattern analysis - how to read stock charts

Here are five patterns analysts reference most:

1. Double Bottom (W-shape)
The price hits a low twice, then rebounds. Interpreted as a strong support signal — "it won't go lower than this."

2. Head and Shoulders
Left shoulder → head (highest point) → right shoulder. A classic reversal pattern signaling the end of an uptrend.

3. Triangle (Converging)
Highs get lower and lows get higher, forming a triangle. A decisive breakout often follows.

4. Golden Cross / Death Cross
When the short-term moving average crosses above the long-term average it is called a golden cross (a bullish technical pattern). Crossing below is a death cross (bearish pattern). These are observed historical patterns — they do not guarantee future returns.

5. Gap Up / Gap Down
When trading opens significantly above (or below) the previous close. Usually driven by major news or events.

Even Experts Get It Wrong — The Limits of Charts

Chart analysis is a useful tool, but it's not a crystal ball. Different experts read the same pattern differently, and the market often moves contrary to expectations.

During the 2020 COVID crash, many chart analysts predicted further declines — yet the market staged a dramatic V-shaped recovery. Charts reflect historical data patterns only; they can't account for future events like pandemics or policy shifts.

That said, developing chart-reading skills does help. At minimum, it gives you a sense of whether you're near a peak or a bottom.
