Market cycles: why markets boom and bust

Markets don't rise in a straight line — they move in cycles of optimism (expansion, rising prices) and pessimism (contraction, falling prices), driven by the economy, corporate earnings and investor sentiment. Every generation of Indian investors has lived through these swings: the 2008 global financial crisis, the sharp COVID crash of March 2020, and the strong recoveries that followed each. The pattern repeats because human behaviour repeats — greed stretches valuations near the top, and fear compresses them near the bottom.

The four phases of a cycle

• Accumulation: after a fall, prices stabilise. Pessimism is high, valuations are cheap, and patient money quietly starts buying.
• Expansion: earnings improve, confidence returns, prices climb — the longest and most rewarding phase.
• Euphoria: everyone is bullish, new investors pour in, and valuations run ahead of fundamentals. This is when discipline matters most.
• Contraction: a trigger — rate hikes, a global shock, an earnings slump — deflates prices, often by 20-40% for equity funds, and the cycle resets.

Why this matters for your SIP

Suppose you run a ₹10,000 monthly SIP through a full cycle. When the market falls 30%, your instalment buys roughly 43% more units than it did at the peak. When the recovery comes, those cheap units do the heavy lifting for your overall return. This is rupee-cost averaging working with the cycle — but it only works if you keep investing through the ugly phase, which is exactly when most people stop.

Common mistakes cycles cause

• Timing the top or bottom: no one reliably does it — even professional fund managers get it wrong. Missing just the few best recovery days can cost a large slice of a decade's return.
• Chasing the hottest category late in a bull run: the funds topping one-year charts near a peak are often the ones that fall hardest next.
• Stopping SIPs in a bear market: this converts temporary losses into permanently missed cheap units.

Reading the cycle without predicting it

You don't need forecasts to be cycle-aware. Simple habits do the work: rebalance once a year back to your target equity-debt split (which automatically books some profit in euphoria and buys more equity after falls), prefer valuations-conscious categories like balanced advantage funds if swings unsettle you, and keep 6-12 months of expenses out of equity entirely so a bear market never forces you to sell at the bottom.

The takeaway

You cannot control the cycle, but you can control your behaviour inside it: keep the SIP running, rebalance occasionally, and judge funds on how they behaved across a full cycle — not one good year. Rolling returns and drawdown history on each Dhanik fund page show exactly that. The lesson stays the same: time in the market beats timing the market. Mutual fund investments are subject to market risks; this is education, not advice.
