雷區(qū):Equity Investments
探雷:
我們知道,如果按交易方式劃分二級市場,中國的A股市場是屬于指令驅(qū)動市場(order-driven market)的,也就是由broker撮合交易,buyer買單和seller賣單共同驅(qū)動形成股票的交易價格。在這其中同學們又會學到“限價指令簿”(limit book order)的概念,而像”take the market”、”make the market”、”make a new market”等一系列名詞大多數(shù)同學有時還是會似懂非懂。
排雷:
下圖為limit order book。
 

 
Bids price是買單報價(26,25,24,23,22,21),ask price 是賣單報價(33,32,31,30,29,28)。
其中Best bid:*6買單報價26;Best ask/offer:最低賣單報價28.
“Make the market”指limit buy price 26; limit sell price 28,訂單不能馬上成交。
“Make a new market”指limit buy/sell price between 26 and 28,出現(xiàn)新的報
價, 訂單不能馬上成交。
“Take the market”指 limit buy price and limit sell price能導致訂單馬上成交。
例題:
Currently, the market in a stock is”$54.62bid, offered at$54.71.” A new sell limit order is placed at $54.62. This limit order is said to:
A.  take the market.
B.  make the market.
C.  make a new market.
Answer:A
解析: limit sell price 54.62 指股價在54.62以上才賣股票, 而剛好現(xiàn)在市場是54.62 bid,所以訂單可以以best bid馬上成交,這是take the market。
