Shorts in pure Cash Market

Hi all,

this may have been discussed before but my search didnt find it.

this is only for cash market discussed below

Many a times we hear the word “SHORT COVERING”.

  1. when did those shorts happen
    2)where they naked shorts?
  2. if SLB then is the data available in NSE of those stock quantity
  3. is there any other institution/Brokerage that lends stocks for such shorting
  4. do MF,FII short ? if so is it naked short or short on paper ( buy stocks before the quarter ends to show as holdings)

kindly throw light on the same …
thanx in advance
