How to Read This Data
Avg Return is the mean percentage change over the 21 trading days (≈ 1 month) following each calendar date, averaged across the years AZO was traded.
Win Rate shows how often that forward month finished positive. A 75% win rate means AZO rose over the following month in 3 of every 4 years you invested on that date.
Samples is the number of years that contributed to the date. Calendar dates that fall on weekends or holidays in some years naturally have fewer samples; only dates with enough history are ranked.
Seasonal patterns are historical tendencies, not guarantees. A specific calendar date is a rough proxy for a seasonal window — treat it as one input alongside your own research, not a precise timing signal.

Frequently Asked Questions
What is the best day of the year to invest in AZO?▾
Based on 36 years of data, October 19 has historically been the best day to invest in AZO. Buying on that date and holding for ≈ 1 month returned an average of +6.40% with a 88% win rate.
Does buying on one specific day really matter?▾
A single calendar date is a proxy for a seasonal window rather than a precise signal. The dates that rank highest tend to cluster around genuinely strong seasonal periods, which is why we also show the best day within each month and link through to the broader best month analysis.
How is this calculated?▾
For each calendar date we measure the return over the following 21 trading days (≈ 1 month) if you had bought on that date, using daily closing prices from 1991 to 2026, then average across all years. The date with the highest average forward return is the historically best day to invest.
Is this trading or investment advice?▾

It is not financial, investment, or trading advice and is not a recommendation to buy, sell, or hold AZO or any other security. Past performance does not guarantee future results — always do your own research and consult a qualified financial advisor before investing.
