Thanks.
Do you know if there is a way that can tell who is buying or selling in such changing-hands action? (MM1->MM2, MM1->Institution1, Institution1->MM1, or Institution1->Institution2?)
Could be some vip of the company sell their holdings, or changing hands between the investment company.
no idea how to find out who is buying and who is selling. check if there is any inside selling. sometimes, CEO or CFO of the compay sell their holdings and investment company will buy and it won't affect mkt price.
1) It is related to the topic
2) Not everybody is watching MU, I provided them the related information to save them time.
3) I used my program to get the info, a good useful practice and testing.
其实这只是收盘时候,Stock Exchange 按照规定settle last period transactions, 这是为了杜绝人为操纵收盘价格的行为,所以最后的收盘价是最后一个时段内的交易价格,并非最后一个单子的价格。
粗看好像有机构的buy at close @9.73, 这是Market Maker 接受的一种机构单子, 指定buy at close 或者Sell at Close, 价格以收盘价格为准(下单时候价格不能确定),机构下这种单子好像要在3:30pm 之前,否则market maker 可以拒绝,3:30pm 之后,已经下的单子不能取消。Market Maker 会根据手中的单子净量决定自己的策略,例如是先卖空,后平仓; 还是先买入,后卖出平仓。
maybe MM has a lot of inventories...although the sell order is smaller than buy order, but MM can always match the buy orders...therefore, supply meets demand and price does not go up...
