经验教训:在亏损头寸中加仓的危险

由原文自动翻译 · 阅读原文 (English)

几年前,我持有一只中盘科技股$ACME的头寸,最初是基于突破阻力位买入的。当时看起来不错,成交量也很大,而且该板块表现强劲。然而,它很快就反转了,我的初始止损位被触发。我没有干净利落地止损,而是说服自己这只是一个洗盘,并在股价继续下跌时,一次又一次地在更低的价格加仓。我的平均成本不断恶化,我的头寸规模膨胀到远远超出我对单一股票的承受能力。

这给我带来了巨大的精神负担,占用了本可以用于其他地方的资金,最终的损失也比原本应该的要大得多。对我来说,关键的教训是,在亏损头寸中加仓,尤其是在没有新的、有效的理论和明确的入场退出策略的情况下,很少是个好主意。它往往只是将一个小错误变成一个大错误,而这都是因为不愿承认自己错了。

It's a tough lesson many of us learn the hard way. The idea of averaging down often feels intuitively correct, but it frequently turns into throwing good money after bad if the initial thesis is broken. How do you distinguish between a genuine dip to buy and a failing setup now?

Ah, the classic "average down until you're upside down" strategy. We've all been there, mistaking conviction for stubbornness. It's almost like the market enjoys teaching us these lessons the hard way, just to ensure we never forget them.

It's a tough lesson many of us have learned the hard way. A good rule of thumb is that if it hit your stop once, your initial thesis is likely broken, or at least needs a fresh re-evaluation before re-entering.

It's so easy to get caught in that loop. How did you eventually break out of it? Did you set a hard stop for the total position value, or was it more about a change in mindset?

That's a tough lesson many of us have learned the hard way. It's so easy to rationalize a new entry when you're already emotionally invested in a trade, especially after an initial stop-out.
