推特有效用戶下降，股價下跌19%

Shares in Twitter dropped close to 20 percent Friday after the social media giant reported a fall in active users.

Twitter said it had 335 million monthly users in the second quarter of the year, which was down a million from the amount of monthly users in the first quarter of the year, and below the 339 million users Wall Street was expecting.

Twitter said that the number of monthly users could continue to fall next quarter as it continues to ban accounts that violate its terms of service and makes other accounts less visible.

The company says it is putting the long-term stability of its platform above user growth. However, the move has made it more difficult for investors to value the company as they rely on data of the platform's potential user reach.

Shares in Twitter closed at $34.12 Friday. The fall in share prices came despite Twitter reporting higher than expected revenue. During the last quarter, Twitter posted a profit of $100 million, marking the company's third consecutive quarter in profits.

The drop in Twitter shares comes a day after Facebook lost 19 percent of its value.

Facebook said Thursday that slower user growth in big markets and increased spending to improve privacy would hit margins for years, leading to the company's worst trading day since it went public in 2012.社交媒體公司推特報告其有效用戶數量減少後，公司股票價格星期五直落將近20%。

推特公司說，2018年第二季度的單月有效用戶是3億3500萬，比第一季度減少了100萬，並低於華爾街預期的3億3900萬。

推特說，單月有效用戶的數量下一季度可能還會繼續減少，公司在繼續關閉違反服務協議的賬號，以及降低某些賬號的突出地位。

推特公司說，這個社交平臺的穩定比用戶增加更重要。不過，這使得投資者更難評估公司的價值，因爲他們的主要標準是這個社交平臺潛在的用戶數量。

推特股票星期五以34.12美元收盤。推特報告了高於預期的營收，但股票仍然下跌。推特上一季度的利潤爲1億美元。這是推特連續三個季度盈利。
