Hindenburg Omen 是极少见的 technical indicators 之一。想当初,咱做 analyst 的时候,咱得从 Bloomberg 下载数据自己重建这个 indicator 并 fine tune the parameters — percentage threshold of NYSE new highs & new lows, and NYSE breadth that was used to calculate the McClellan Oscillator。现在网上有现成的了,只是无法查看整个历史。尽管近日 (5/23/2024) 股市出现了一个 Hindenburg Omen (二月份出现过一次, 2/2/2024),但是在primary trend 是牛市时,要使得它有效,其中有一个重要因素必须考虑,即30天内出现多个 omens(1/10/2022)。当 down trend 清晰建立了时,单个 Hindenburg Omen 也能 signal impending crash(例如 4/8/2022)。道理很简单,the existing bull market 不断气便不死,所以即使是极端情况,market 不陷入绝境是不会 give up and crash 的。但是一旦 down trend 形成了,推波助澜诱使韭菜 panic 就比较容易了 (不过有些版本强调 the market trend must be upward, which shouldn’t be a requirement)。Hindenburg Omen 刚一出现算是给 market participants 敲响警钟,提醒他们密切注意market近期发展,一旦 downside momentum picks up, the probability of market crash increases。其实,market crashes (true events) 伴随着 Hindenburg Omens 比 Hindenburg Omens 预示 market crashes 更可靠 (false signals)。这也是为什么本来就稀少的 Hindenburg Omens 平时被关注得就更少了。正如 Paul Samuelson 所调侃的 “the stock market had predicted nine of the past five recessions”, 在过去的 5 年里,Hindenburg Omens predicted nine of the past two stock market crashes. 看看这次 Hindenburg Omens 能不能 improve its odds of success to “predict 9 of the past 3 stock market crashes”。所以,similar to any forecasting tools, Hindenburg Omens must combine with other indicators to improve their accuracies of forecasts.
