雷區(qū):Equity Investments
探雷:
我們知道,如果按交易方式劃分二級(jí)市場(chǎng),中國(guó)的A股市場(chǎng)是屬于指令驅(qū)動(dòng)市場(chǎng)(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(dòng)形成股票的交易價(jià)格。在這其中同學(xué)們又會(huì)學(xué)到“限價(jià)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(xué)有時(shí)還是會(huì)似懂非懂。
排雷:
下圖為limit order book。
 

 
Bids price是買單報(bào)價(jià)(26,25,24,23,22,21),ask price 是賣單報(bào)價(jià)(33,32,31,30,29,28)。
其中Best bid:*6買單報(bào)價(jià)26;Best ask/offer:最低賣單報(bào)價(jià)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(bào)
價(jià), 訂單不能馬上成交。
“Take the market”指 limit buy price and limit sell price能導(dǎo)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(jià)在54.62以上才賣股票, 而剛好現(xiàn)在市場(chǎng)是54.62 bid,所以訂單可以以best bid馬上成交,這是take the market。
