2、空方和空头一样吗

多头和空头持仓是一样多的 但是你看到的数据 多头持仓 是主动做多的,实际隐藏了做空的对手盘 空头持仓 是主动做空的,实际隐藏了做多的对手盘 所以你会有所误解,就像你在行情软件右下角看到的激武讨成交数据一样,都是偶数倍的数字,比如 多开 现手10,实际上是5手做多,同时隐藏了5手 对手盘数据


空方和空头一样吗

3、空头方向是什么意思

多头的定义
  多头是指投资者对股市看好,预计股价将会看涨,于是趁低价时买进股票,待股票上涨至某一价位时再卖出,以获取差额收益。人们通常把股价长期保持上涨势头的股票市场称为多头市场。多头市场股价变化的主要特征是一连串的大涨小跌。多头是相信价格将上涨而买进某种金融工具,期待涨价后高价卖出的市场人士。与空头相反。
  多头代表了一种实际操盘方向,并非指特定的人群,并不是说买的人多就是多头,而应当说多方力量大于空方。多头指标只能对投资者起到一定的参考意义,并不能作为投资的决定因素。另外,多空的走势需要一定的时间才能转换,所以一般会落后于股票的实际走势。

  空头的定义
  空头是投资者和股票商认为现时股价虽然较高,但对股市前景看坏,预计股价将会下跌,于是把借来的股票及时卖出,待股价跌至某一价位时再买进,以获取差额收益。空头指的是变为股价已上涨到了最高点,很快便会下跌,或当股票已开始下跌时,变为还会继续下跌,趁高价时卖出的投资者。采用这种先卖出后买进、从中赚取差价的交易方式称为空头。人们通常把股价长期呈下跌趋势的股票市场称为空头市场,空头市场股价变化的特征是一连串的大跌小涨。
  股价变化是由多头和空头的力量对比所决定的。多头会预测价格上涨,从而作出购买决策。空头因为预测价格将下跌,将会抛售手中的股票。如同其他的交易一样,当多头和空头在价格上达成一致时,就达成了交易。
空头方向是什么意思

中国的股票是单向的,不存在做空机制(在股指期货出来前)
所以没有真正的空方存在.

国外有!

多方,就是买进股票,希望股票能涨上的一方.从而他们能活力的一方.
空方,就是手上没股票,希望股票下跌,他们可以抄底的一方.
多方:看涨的人 空方:看跌的人
多方是指市场中买入证券的一方.空方就是卖出证券的一方.
