Bull Market

Sustained period of rising prices, typically 20%+ from a recent low. Investor sentiment is optimistic and risk appetite high.

What a bull market is

A bull market is a sustained period of rising asset prices, typically defined as a 20%+ rise from a recent market low. The term originated in the way a bull attacks — thrusting upward with its horns.

Bull markets are characterised by high investor confidence, increasing capital flows into equities, expanding valuations, and a self-reinforcing optimistic narrative.

Recent major bull markets

2009 – 2020: the longest US bull market on record. The S&P 500 rose ~400% from the GFC low. Ended with the COVID crash in March 2020.

April 2020 – Jan 2022: post-COVID bull. S&P 500 doubled in 21 months, driven by stimulus and tech.

Oct 2022 – present: current US bull market, AI-driven, focused in mega-cap tech.

Singapore STI: less dramatic but synchronously bullish — typically follows global trends with a 6-month lag.

Bull market behaviour

Volatility tends to compress: drawdowns are shallow and infrequent in established bull markets.

Sectors that lead rotate: bull starts often led by quality and defensives; mid-bull by cyclicals and growth; late-bull by speculative segments (small-caps, IPOs, crypto-adjacents).

Valuations stretch: P/E ratios climb as price growth outpaces earnings growth. By peak, valuations often look unsustainable to long-term observers.

Investor behaviour during bulls

FOMO trap: investors who sat out the early bull years often capitulate near peaks, deploying capital just as the cycle is ending. Worst possible timing.

Underestimating duration: bulls last longer than most observers expect. Calling 'the top' in years 5 – 8 of an 11-year bull is a common mistake.

Discipline matters: keep contributing through bull markets, but resist increasing risk above your target allocation. Rebalance into bonds as equities outperform.

Cash drag: holding too much cash 'waiting for a correction' costs returns. The opportunity cost of timing the market consistently dwarfs the savings from buying a few percent lower.

Frequently asked questions

What is a bull market?

A sustained period of rising asset prices — typically defined as a 20%+ rise from a recent low. Named after the upward thrust of a bull's horns. Characterised by high investor confidence, rising valuations, and self-reinforcing optimism.

How long do bull markets typically last?

Average ~5 years historically, with wide variance. The 2009 – 2020 bull was 11 years (longest US bull on record). Post-COVID 2020 – 2022 was 21 months. Current cycle (Oct 2022 – present) is ongoing. Bulls last longer than skeptics expect.

Should I sell at the top of a bull market?

Hard to call the top. Most investors who try lose more to mistimed exits than to participating in the eventual bear. Stick to your target allocation; rebalance to trim winners as bonds underperform; keep contributing rather than 'sitting out' on cash.

How does a bull market end?

Recession, rate shocks, valuation collapse, or sentiment exhaustion — sometimes all at once. Bear markets typically follow. Bulls don't 'die of old age' — they die from specific catalysts. Watch macro signals (inverted yield curve, rising unemployment) but don't try to time exact tops.
