摊平操作?小心被“摊平”的是你自己 | 胡立阳
投资人问:
最近股市表现不佳,我的股票也跟着倒霉,一口气暴跌了20%,很想趁低再买进一些来降低成本,否则将来还不知道要等到什么时候才能解套呢!这样做,对吗?
悬崖勒马
每次股票下跌,都会有人在问是否可以逢低补仓以降低成本?老实说,我不赞成!因为过去看过太多例子,能幸运解套的少,反而是越陷越深的多。
当股票骤然下跌时,多数投资人会硬着头皮加码买进,一心期盼能摊低进货成本,以后只要来个反弹,就可以不必苦等股价回到最原先的买进价位,提早安全下车了。
我并不鼓励这种做法,有两个理由:
(1)加码容易激发赌性,造成错上加错。当第一次做出的决策根本就是个错误,那当然就会越陷越深,永难回头。等到加码两三次后,更会激发“豁出去算了”的赌性,造成一败涂地的下场,也印证了所谓的“一步错,全盘错”。
(2)摊低成本的做法在理论上并没有错,但问题在于没有人知道股价到底要到什么价位才会反弹,如果没有长期投资的心理准备,绝对会虎头蛇尾,全军覆没。例如,股价从10元下跌,跌到8元时会反弹吗?如果勇敢加码后股价又跌到5元,许多人在绝望之余只有含泪卖出。
正因为难以算计反弹的时机,越买越多的“倒金字塔”式摊平操作,绝对禁止。当股价走势已经和原先预期背道而驰且渐行渐远,应趁早脱身,怎能还去加码买进,小心被“摊平”的是你自己。
