However, at the overall level, which includes institutional and high networth individuals, total dip in folios was capped at 15 lakh due to gain in the folios held by high networth individual.
By the end of September, total number of folios stood at 4.13 crore as per Amfi data.
Giving the reason for such massive fall in retail folios, the rating agency said that volatility in equity market had prompted such investors to exit.
"The sharp decline in retail folios was mainly in the equity category which was impacted by volatility," the report said.
It also said balanced funds, which is an equity-oriented hybrid category, also witnessed a decline of over 2 lakh retail folios during the reporting period.

"Out of the 30 lakh HNI folios, 21 lakh were added in the latest half year period," it said.
Indicating the loosing sheen of gold as an asset class, gold ETFs witnessed a fall in retail folios for the first time.
"Retail folio count in the category fell by 5 per cent to 5.24 lakh in the period under review compared with a 16 per cent rise in the preceding six months," it said, adding that fall in gold prices as the reason behind such decline.
However, debt funds continued to attract retail investors with the category witnessing a rise in retail folios since March 2009.
According to Crisil, debt funds added 1.79 lakh folios during the first half of this fiscal against 1.69 lakh added in the previous six months. However, amid rising concerns of exits by retail investors, the report noted that around 68 per cent of retail equity AUM stayed invested for over two years.
