Questions
What are the best months to buy stocks?
It depends on the stock. SeasOptima shows, for any symbol, which calendar months have historically had the highest average return and win rate over up to 30 years - so the answer is specific to each company, ETF or index, not a single rule of thumb.
How is each month scored?
Each month shows its average historical return and the share of years it was positive (win rate), colour-coded from very weak to very strong across up to 30 years of split- and dividend-adjusted data.
Do the best months repeat every year?
No. Monthly seasonality is a statistical tendency based on historical data, for educational and informational purposes only. It is not investment advice and past performance does not guarantee future results.
Is it free?
You can view the monthly heat map on individual symbol pages for free. Screening the whole market for the best months and the advanced tools are part of SeasOptima Premium.
