做T+0为什么要出一半留一半，我在高位出九成，留一成，等低位的时候买回九成岂不是比出五成买回五成更好？
推荐回答（3个）
理论上你的想法并不同有错，但是谁也不能保证自己的每次操作都能百分之一百的准确，如果事如愿违，并没有出现你所想象的情况，你认为的高位把股票卖出后，股票却继续上涨了，你是否会在高位把卖出的股票买回来，若你卖出九成，你卖出九成的资金相对于已经上涨上去的股票价格来说购买力已经下降了，若与五成的情况相比较损失会小一点。
对于五成和九成，在上涨时五成的损失较小，但在下跌时五成的收益也小，九成却与五成的情况相反。
实际上这一个是自己对于仓位控制和交易风险理解的问题。
当然你可以，别说九成就是全仓出完然后再低位买回都是可以的，每个人的操作方法不一样，出一半留一半可能是由于这个人对未来的走势不很确定，怕出的多了踏空行情，所以出一半留一半。
每一次的行情总是在绝望中诞生，而又在股票割肉后上涨。为什么有人能常胜，把股市当作“提款机”，而你总在行情差的时候深套其中，行情好的时候踏空或者一次次坐了电梯？证券市场，说简单也简单，说难也难. 其实做股票就是做心态 心态决定状态,脑袋才是决定口袋! 脑袋一定要跟上变化！因此，在牛年，投资者适当降低预期，以积极的心态参与市场是可取的，而始终沉迷于去年亏损的泥泞中，裹足不前是不可取的。大师说过，在别人悲观的时候，是你买入股票的机会。而实际上，从政策和行业的角度来看，大并购，产业整和，周期行业复苏，二级市场并购，金融创新等主题中蕴藏不少牛股。牛年股市擒牛股，我们将和大家好好把握。不要再交学费买经验了跟上我们的脚步吧！有诚信达成合作的股民请加入腾讯 76 99 23 605 股海论金
