Frequently Asked Questions
What is stock seasonality?
Stock seasonality refers to recurring, statistically significant patterns in equity performance during specific calendar months. These cycles are driven by quarterly corporate earnings seasons, fiscal year-end dynamics (March in India), advance tax payments, festive consumption spikes, and global fund rebalancing.
What is historically the best month for Indian equities?
July holds the highest historical win rate on the Nifty 50 at 64.9%, closely followed by June (63.9%) and December (61.1%). December delivers the highest average monthly return at +3.10% across 36 years of recorded market history.
Why does 'Sell in May and Go Away' fail in India?
Global markets often slow down during Northern Hemisphere summers, but India's major festive season (Navratri, Diwali, and Dhanteras) across October to December creates a powerful festive demand rally. May itself has a healthy 58.3% win rate in India. The actual weak window for Indian markets is March (38.9% win rate) due to FY-end advance tax liquidity outflows.
Which calendar month is the weakest for Nifty?
March is historically the most challenging month with a 38.9% win rate and the only consistently negative average return (-0.88%). This is caused by March 31 financial year-end portfolio cleaning, tax-loss harvesting, corporate advance tax deadlines, and institutional NAV adjustments.
What does the Positive Return Ratio indicate?
The Positive Return Ratio measures the percentage of historical years in which a specific month ended with net positive gains. A 64.9% ratio for July means that in nearly two-thirds of all recorded years, July produced positive equity returns.
How should I incorporate seasonality into trading decisions?
Seasonality is an edge enhancer rather than a standalone trading trigger. Combine monthly historical win rates with technical momentum (stocks above 200 EMA) and fundamental valuation to enter trades when historical probabilities are statistically aligned in your favour.
