As on 1st September 2015 Sun & Jupiter in Leo, Mercury & Rahu in Virgo, Saturn in Scorpio, Moon & Ketu in Pisces and Mars & Venus in Cancer. Planetary transits in September: 15th Mars -> Leo, 17th Sun -> Virgo, 30th Venus -> Leo.
The planetary positions given above are at the time of Sunrise in India(Kerala) and Moon's conjunction effect on markets may be seen in countries (Asia / Europe / US) where trading take places at the time of conjunction(0°). When the angular difference between the Moon and the planet is more than 5 degrees or conjunction occurs in Rasis(constellations) other than the Sun's Rasi, there may be a delay up to 24 hours in the conjuntion effect according to their positions (Note: expect only eighty percent accuracy in assumptions based on Moon's conjunction with Mars(-), Venus(-) and Jupiter(+) as some other astro factors may also influence the market). As Moon conjuncts with Venus and Mars on 10th Nifty may move downwards on 10th & 11th. From 17th September to 10th October Mercury is in retrograde and Nifty may move down 250 to 400 points to give a buying opportunity around 10th October. (Last Mercury retrograde ended on 12th June 15 and Nifty low 7940 on that day, Nifty low 8470 on 10th Feb 15 retrograde ended on 12th Feb, Nifty low 5972 on 13th Nov 13 and retrograde ended on 10th Nov). Thereafter, an upmove is excepted before Jupiter goes retrograde in January 2016.
