Key Takeaways

Four stages of a bull market: 1) Accumulation (low-level oscillation, institutions quietly buying); 2) Markup (price rising, breaking previous highs); 3) Distribution (high-level oscillation, institutions distributing); 4) Markdown (sharp decline, panic selling). The reverse applies for bear markets. Identifying the current stage helps you adjust positions — increase weight at lows, reduce at highs.

Why Understand Market Cycles?

Markets do not move randomly — they follow identifiable cycle patterns. Understanding cycles helps you: buy at lows instead of chasing highs, reduce positions at highs instead of selling at lows, and adjust your mindset by knowing which phase you are in.

As the famous investing saying goes: "History does not repeat itself, but it often rhymes."


The Four Stages of Market Cycles

Stage 1: Accumulation

The market has just experienced a major decline, sentiment is extremely pessimistic, valuations are at historical lows, and volume is low. "Smart money" begins quietly entering. Retail investors are fearful and selling at a loss, while institutions gradually build positions.

Strategy: Buy quality assets in batches, be patient (may last months to years), do not expect immediate upside.

Stage 2: Markup

Prices begin to rise steadily, valuations recover from lows, volume increases, and media starts reporting the recovery. Retail investors enter hesitantly while institutions continue adding positions.

Strategy: Hold core positions, may moderately add, set trailing stop-loss to protect profits.

Stage 3: Distribution

Prices oscillate at highs, valuations are at historical highs, volume is high but prices are not advancing, media is euphoric and everyone talks about stocks. Retail investors rush in fearing they will miss out, while institutions quietly reduce positions.

Strategy: Gradually reduce positions to lock in profits, do not chase highs, increase cash ratio.

Stage 4: Markdown

Prices begin to decline, valuations contract, panic selling may occur, media turns pessimistic. Retail investors panic and sell at a loss, while institutions have already significantly reduced or eliminated positions.

Strategy: Maintain high cash ratio, do not rush to buy the dip, wait for accumulation phase signals to appear.


How to Identify the Current Cycle Position?

Valuation Levels

Accumulation: P/E at historical lows, high dividend yields. Markup: valuations are reasonable. Distribution: P/E at historical highs, low dividend yields. Markdown: valuations contract rapidly.

Market Sentiment

Accumulation: retail investors extremely pessimistic, VIX at highs. Distribution: retail investors extremely optimistic, media euphoria, new account openings at record highs.

Accumulation: price oscillates around 200MA, volume low. Markup: price holds above 200MA, volume increases. Distribution: high-level oscillation, volume high but price stalls. Markdown: breaks below 200MA, volume surges (panic).

Markup80-100%Growth stocks, strong sectorsHold, let profits run
Distribution40-60%, gradually reduceDefensive stocks, cashBe fearful when others are greedy
Markdown0-30%Cash, bonds, goldProtect capital, wait for opportunities

Common Mistakes

Mistake 1: Chasing Highs During Distribution

Seeing others make money and jumping in, only to buy at the top. When everyone says "this time is different," it usually is not.

Mistake 2: Selling at a Loss During Accumulation

Unable to endure the prolonged downturn and selling, missing the subsequent rally. Accumulation is the stage that most tests your patience.

Mistake 3: Trying to Predict Exact Turning Points

No one can precisely predict cycle turning points. Use "range thinking" instead of "point thinking."

Mistake 4: Always Being Fully Invested

Being 100% invested at all times means you will also be fully invested during distribution, which significantly reduces long-term returns.


Summary

Core lessons of market cycles:

  1. Buy during accumulation — be greedy when others are fearful
  2. Hold during markup — let profits run
  3. Reduce during distribution — be fearful when others are greedy
  4. Defend during markdown — protect capital, wait for the next opportunity
