9. Reading Stock Trends: Moving Averages, Support and Resistance

Investing Styles and Strategies – 10 posts for beginners | Post 9 of 10

Prices move up and down every day, which can make a chart look like random noise. Learning to see the underlying trend is one of the most useful skills for any market participant.

The three types of trend

  • Uptrend (bullish) – the price makes higher highs and higher lows.
  • Downtrend (bearish) – the price makes lower highs and lower lows.
  • Sideways trend (range) – the price moves within a band without a clear direction.

Trends never move in a straight line. Even a strong uptrend has pullbacks along the way.

Three types of trend

Moving averages smooth the noise

A moving average is the average closing price over a set number of days. For example, a 50-day moving average adds the last 50 closing prices and divides by 50. Each day the oldest price drops off and the newest is added, so the line "moves".

  • A rising moving average suggests an uptrend.
  • A falling moving average suggests a downtrend.
  • Widely watched averages include the 20-day (short term), 50-day (medium term) and 200-day (long term).

When the price stays above a rising 200-day average, many investors consider the long-term trend healthy.

Moving average

Support: the floor

Support is a price level where a falling stock has repeatedly stopped falling and bounced back. At this level, demand has historically been strong enough to absorb the selling.

Resistance: the ceiling

Resistance is a level where a rising stock has repeatedly stopped rising. Supply at this level has historically been strong enough to cap the price.

When a price moves decisively through resistance, that old ceiling often becomes a new floor. The reverse is also true.

How to find trending stocks

  • Volume increases – trends are usually backed by rising trading volume.
  • Relative strength – compare a stock's performance with the Nifty 50. Stocks that rise more than the index in good times and fall less in bad times show strength.
  • News flow – new orders, policy changes or strong results can start or extend trends.

A word of caution

Technical tools describe what has happened; they do not guarantee what will happen next. Support can break, resistance can give way, and trends can reverse suddenly. Use these tools to understand the market and plan your risk, not as a promise of profit.

Key takeaways

  • Identify the trend first: up, down or sideways.
  • Moving averages smooth daily noise and show direction.
  • Support and resistance highlight important price zones, but they can break.
