摘要

信息是资本市场的关键因素之一。在这种情况下,资本市场的股价往往会出现上涨或下跌的模式。2023 年初,多家发行人因被怀疑股价异常波动而获得了 UMA 状态。本研究以 24 家处于异常市场活动(UMA)状态的发行商为样本。观察期为 2023 年 1 月至 2 月,或被观察发行人的 UMA 状态公告期。研究结果表明,在 90%、95% 和 99% 的置信水平下,大多数发行人的股价波动模式都不寻常。然而,本研究亦發現,部分股票市場價格模式趨向於在置信水平範圍內,因此傾向被稱為正常。

Analisis fluktuasi harga saham “Unusual Market Activity”
Information is one of the crucial factors in the capital market. This condition tends to be followed by stock price patterns that can experience increases or decreases in the capital market. In early 2023, several issuers obtained UMA status because they were suspected of having unusual share price movements. This study uses 24 issuers that are in conditions of unusual market activity (UMA) as samples. The observation period is January to February 2023 or the period for announcing the UMA status of the issuers being observed. The findings of this study show that the majority of issuers have unusual stock price movement patterns at the 90%, 95%, and 99% confidence levels. However, this study also found that some stock market price patterns tend to be within the confidence range so they tend to be called normal.
