@Crow bhai,
@k l patel bhai,
Market maker is a psychological cushion, so to say. They are expected to provide 2-way quotes, i.e. liquidity. My understanding is, they are to ensure the stock doesn't hit either circuit easily (at least 75% of the session).
If you look at the recent Accent Microcell listing, it first made a high of 10 paise below upper cricuit, then hit low of lower circuit (but buyers were always there). So, probably MM played a part here on both sides.This mechanism especially generates some confidence in those issues which don't have QIB quota.
But SME listings are replete with examples where this doesn't happen. Even Accent did hit upper freeze later. Probably because the buying or selling qty (pressure) exceeds the MM portion - then they are helpless.
@Basuvr ji may correct me.
