Is any weekday better for NIFTY? Two years of day-of-week returns
Trader folklore is full of weekday superstitions. We checked NIFTY's actual day-of-week pattern: the average close-to-close move on each weekday, over two years. Here's every session sorted by the day it landed on.
| Weekday | Avg move | Win rate | Total points | Sessions |
|---|---|---|---|---|
| Monday | +13.4 | 58.5% | +1,259 | 94 |
| Tuesday | −7.3 | 56.1% | −716 | 98 |
| Wednesday | +14.1 | 58.3% | +1,356 | 96 |
| Thursday | +8.0 | 53.0% | +802 | 100 |
| Friday | +34.4 | 54.6% | +3,334 | 97 |
Friday did the heavy lifting
Friday averaged +34 points a day — more than double any other weekday and worth +3,334 points on its own. Tuesday was the only loser, averaging −7. Curiously, Tuesday still won 56% of its days: it lost because its down days were bigger, not more frequent — the same win-rate-lies lesson from elsewhere on this blog.
Takeaway
In this window NIFTY's gains clustered on Fridays and Tuesday was flat-to-down. Interesting, and consistent with some global weekday studies — but far too small a sample to bet on. The honest use of seasonality is context and awareness, not a standalone edge.
