SIP in Bull vs Bear Markets

How SIP behaves differently across market cycles and why crashes are actually beneficial for long-term SIP investors.

Bear Markets Are SIP's Best Friend

SIPs started during or just before bear markets have historically delivered 20-30% better long-term returns than those started during bull markets. This is because Rupee Cost Averaging accumulates more units at lower prices during crashes.

SIP vs Lump Sum Returns Across Market Phases

Approximate annualized returns during each market phase (Nifty 50 based)

Bull Market Behavior

Lump sum tends to outperform SIP in sustained bull runs
SIP buys fewer units at higher prices, diluting average returns
SIP still delivers solid returns — just not as high as lump sum
SIP protects against the risk of investing at the absolute peak

Bear Market Behavior

SIP significantly outperforms lump sum in bear markets
More units accumulated at lower prices = better recovery returns
SIP loss is much smaller (e.g., -8% vs -52% lump sum in 2008)
Continuing SIP during crashes is the single best action

Key Takeaways

SIP protects against downside risk — your losses in bear markets are much smaller than lump sum

In bull markets, SIP may underperform lump sum, but it still delivers strong positive returns

Over a full market cycle (bull + bear), SIP and lump sum returns tend to converge

The real power of SIP emerges over 10+ year periods spanning multiple cycles

Never stop SIP during bear markets — those are the months that generate highest future returns

For most investors, SIP is the safer and more practical choice regardless of market direction
