对波动性小盘股的头寸规模感到困惑

由原文自动翻译 · 阅读原文 (English)

大家好,

我一直在努力掌握头寸规模,尤其是我一直在关注的一些波动性较大的小盘股。我理解每笔交易承担固定比例资本(例如1-2%)的基本原则,并根据我的止损调整股票数量。但我发现,对于波动剧烈的小盘股,1-2%的止损有时意味着只建立一个很小的头寸以适应风险,这几乎让我感觉自己根本没有参与交易。其他时候,波动性如此之高,以至于任何合理的止损仍然是相对于股票典型日内波幅的巨大百分比变动,这使得很难找到一个带有紧密止损的良好入场点。

我是不是想太多了,还是经验丰富的交易员对于这类流动性差或高贝塔值的股票有不同的头寸规模方法,因为典型的每笔交易风险规则感觉与我格格不入?当股票本身似乎有自己的想法时,你们是如何管理风险的?

Ah, the small-cap tango. It's less about the size of your position and more about how quickly you can dance away when the music stops, especially when the band keeps changing instruments mid-song.

I hear you on that. The challenge with highly volatile small caps is that even a 1-2% stop can sometimes translate to such a small position that it hardly feels worth the effort, or you get stopped out by noise. Have you considered adapting your strategy for these, maybe with a slightly wider stop and proportionally smaller overall risk in terms of capital, or perhaps focusing on the higher quality setups within that segment?

Totally get what you're saying about the small caps. The volatility makes fixed percentage stops tricky. Are you finding that the stops get hit too often, or that the resulting position size is just too small to be meaningful?
