Moore Threads encountered some volatility in its stock price. Following last Friday's after - market announcement, in which the company stated its intention to allocate no more than 7.5 billion yuan from its IPO proceeds for cash management purposes, its stock initially plummeted by 6% today. Currently, the stock is trading 3% lower than its previous level. (In financial reporting, “experienced stock price fluctuations” is a bit general. “Encountered some volatility” is a more natural and commonly used expression in English financial news. Also, “once fell” is changed to “initially plummeted” to better convey the sudden and significant drop. “Is now down by” is adjusted to “is trading...lower than” which is a more standard way to describe the current stock price situation in English financial contexts.)
