Do you ever stare at the red and green candles of a stock index and wonder whether you should buy now or sell? Most retail investors trade on emotion, but studies show emotional decisions often cause underperformance. For example, Dalbar’s analysis found that due to buying high and selling low, the average investor’s annualized return lagged the market by 2.14%.

Instead of guessing market direction, it’s far better to learn a systematic judgment framework. Winning traders observe trends, interpret market sentiment, and confirm signals with composite indicators to build their own bullish/bearish decision system.

Key Takeaways

• Learning trend, sentiment, and composite indicators helps you accurately judge market direction.
• Moving averages and MACD provide clear buy/sell signals.
• The VIX fear index reveals whether the market is gripped by fear or greed.
• The BBI indicator and price-volume relationships confirm trend strength and authenticity.
• Combining multiple indicators significantly improves accuracy and avoids false signals from any single tool.

Reading Stock Indices: Understanding Bullish and Bearish Trends Through Trend Indicators

The first step in determining market direction is to master “trend” analysis. Trend indicators help you see through daily price noise and identify whether the primary long-term direction is upward or downward. Professional analysts use multiple tools to confirm trends, with the most common indicators including:

• Moving Average (MA)
• Moving Average Convergence Divergence (MACD)
• Relative Strength Index (RSI)
• Stochastic Oscillator

Below, we focus on the most essential and beginner-friendly ones.

Moving Average (MA): Golden Cross vs. Death Cross

The Moving Average is the most fundamental trend indicator. It averages closing prices over a selected period and plots a smooth line, helping you see whether the current price is above or below the average cost.

When a short-term MA (e.g., 5-day) crosses above a longer-term MA (e.g., 20-day) from below, it forms a “golden cross” — typically a bullish signal indicating the market is strengthening. Conversely, when the short-term MA crosses below the longer-term MA from above, it creates a “death cross,” warning of potential weakening and bearish momentum.

MACD: DIF and MACD Line Signals

MACD is an advanced indicator derived from moving averages that reacts more sensitively to price momentum changes. It consists mainly of the fast line (DIF) and the slow line (MACD).

When the DIF crosses above the MACD line from below, a golden cross forms, signaling strengthening upward momentum. When the DIF crosses below the MACD line from above, a death cross appears, suggesting weakening upside or a possible trend reversal. Think of it as a “fast confirmation version” of the MA signal.

Trendlines and Patterns: Breakout and Breakdown Using Box Theory

Beyond mathematical formulas, you can also read trends directly from candlestick patterns. The “Box Theory” is a highly practical method that treats a consolidation range as a box.

Core Concept of Box Trading Price oscillates within a fixed range, forming a box top (resistance) and box bottom (support). A strong upward breakout with volume confirms strong bullish momentum and is a clear buy signal. A downside breakdown indicates bears are in control, and the trend may turn bearish. Patiently waiting for a clear “box escape” is key to improving win rate.

Market Sentiment Indicator: VIX as a Contrarian Signal

If trend indicators tell you the market’s “direction,” sentiment indicators reveal its “temperature.” Understanding whether participants are fearful or greedy allows you to anticipate turning points earlier. The VIX index is the single most important tool for measuring market sentiment.

Understanding the “Fear Index” – VIX

The VIX, officially the CBOE Volatility Index, is compiled by the Chicago Board Options Exchange (CBOE). Known as the “fear index,” it measures the market’s expected volatility of the S&P 500 over the next 30 days based on option prices.

• Core Concept: When the market expects large swings (usually downward), demand for protective puts surges, pushing the VIX higher.
• Inverse Relationship: Generally, when stocks rise, the market is calm and VIX falls; when stocks fall, panic rises and VIX spikes.

Taiwan has its equivalent — the TAIEX Volatility Index (TVIX). The main differences are shown below:

VIX Rolling Over from High Levels: Strong Bullish Signal as Panic Subsides

During major crises (e.g., 2008 financial crisis or 2020 COVID crash), the VIX spiked above 80 — extreme fear levels.

Warren Buffett’s famous quote: “Be fearful when others are greedy, and greedy when others are fearful.” The VIX quantifies that fear.

When the VIX peaks at historically high levels (e.g., above 40) and then clearly rolls over, it is usually a powerful bullish signal. Extreme panic has passed, selling pressure is exhausted, and calm buying returns, greatly increasing the odds of a rebound.

VIX Rising from Low Levels: Bearish Warning of Rising Risk

Conversely, when the VIX lingers in historically low territory (below 20, or even below 10 in 2017), it signals excessive complacency.

At such times, stay alert. If the VIX begins to rise steadily from low levels—even while the index is still making new highs—it can be an early warning that “smart money” is hedging and risk is building. Reducing exposure or staying on the sidelines is the prudent choice. Always compare current VIX levels to its historical range.

Composite Indicators: BBI and Price-Volume Confirmation

After identifying trend direction and sentiment, the final step is “confirmation.” Composite indicators validate signals from multiple angles to avoid acting on a single misleading reading. The BBI and price-volume relationship are two of the most practical confirmation tools.

Bull & Bear Index (BBI): The Market’s Average Cost Battle Line

The Bull & Bear Index (BBI) combines short-, medium-, and long-term average costs into one line—essentially the market’s “average holding cost.”

Formula: BBI = (3-day MA + 6-day MA + 12-day MA + 24-day MA) / 4

When the index stays above the BBI, most participants are in profit → bullish bias. When it falls below the BBI, most are in loss → bearish bias. Traders treat the BBI as a key battle line between bulls and bears.

Price Up + Volume Up vs. Price Down + Volume Up: Confirming Trend Strength

Volume is the market’s fuel. A healthy trend needs volume support.

Volume is like a car’s accelerator. For a trend to run far, it needs fuel (rising volume). If price moves without volume, the trend may be short-lived.

• Price Up + Volume Up: Rising price with expanding volume shows aggressive buying and confidence → high probability the uptrend continues.
• Price Down + Volume Up: Falling price with surging volume usually signals panic selling → strong downside momentum likely to persist.

Price-Volume Divergence: Early Reversal Warning

When price and volume move in opposite directions, it’s called divergence — a major reversal clue.

• Bearish Divergence (Top): Index hits new high but volume is lower than the previous peak → buying power is waning → potential reversal down.
• Bullish Divergence (Bottom): Index hits new low but volume shrinks or fails to expand → selling pressure is drying up → high chance of a bottom.

Real-World Application: Decision Model Using Three-Indicator Confluence

Theory is useless without practice. A single indicator can give false signals, but when trend, sentiment, and composite indicators all point the same way, reliability skyrockets — this is “indicator confluence.”

Build Your Bull/Bear Checklist

Create a simple checklist covering the three categories. When most items align, you have a high-probability confluence signal.

Pro Tip: You don’t need every single box checked. Usually, clear signals from at least two of the three categories are enough for a high-quality trade.

Bullish Confluence Example: Uptrend + Cooling Fear + Volume Support

Imagine you’re watching the S&P 500 and see:

1. 50-day MA crosses above 200-day MA → classic golden cross.
2. VIX spiked to 45, then fell below 30 for a week → panic subsiding.
3. Breakout of previous high with significantly higher volume → healthy price-up/volume-up.

This is a textbook bullish confluence setup. Execution steps:

• Enter in tranches (e.g., 50% of planned position).
• Set stop-loss below the recent consolidation low.
• Target profit using Fibonacci extension (e.g., take 33–50% profit at 1.618 level).
• Trail stop-loss higher as price rises.

Bearish Confluence Example: Downtrend + Rising Fear + Panic Selling

Opposite scenario:

1. Death cross + breakdown of multi-month box bottom.
2. VIX rising steadily from sub-20 to above 25.
3. Sharp price drop with surging volume.

Action: Reduce or exit long positions, raise cash, wait for clear reversal signals before re-entering. Experienced traders may hedge or short via inverse ETFs or options.

Golden Rule: When indicators conflict, do nothing. Reducing position or staying in cash during unclear periods is a victory in itself.

Congratulations — you now master the three pillars of market judgment: trend, sentiment, and confirmation. Research shows combining different indicator types provides a more complete market view and reduces false signals. Start applying these tools today and build your own systematic edge.

As Warren Buffett said:

“The stock market is a device for transferring money from the impatient to the patient.”

FAQ

Do I need to master every indicator?

No. Start with just one or two that suit you best — for most people, MA + VIX is enough at the beginning. Add others gradually as you gain confidence.

What if indicators give conflicting signals?

Wait. Reduce position or stay in cash. Conflicting signals mean the market is unclear; patience dramatically reduces risk.

Can these indicators be used on individual stocks?

Absolutely. All indicators discussed (MA, MACD, volume, etc.) work equally well on individual stocks and help you assess independent trend and momentum.

Where can I view these indicators besides trading software?

Plenty of free resources:

• TradingView – powerful and user-friendly charting.
• Yahoo Finance – built-in technical indicators for indices and stocks.
• Most broker apps include full technical analysis tools.
