and extending into the morning trading.

今早仍持續下跌

Now, for a company of that size,

對於一個規模如此大的公司來說，

that equates to roughly $123 billion of market value evaporating in just one day.

這代表市價在僅僅一天內就蒸發了一千兩百三十億美元

That's the biggest one-day loss of any US company in history.

這是所有美國公司史上一天內虧損最多的紀錄

It is roughly the same as the value of all of McDonald's or even greater than Goldman Sachs, Nike, or General Electric.

這筆數字大約與全球麥當勞的價值相等，或甚至比高盛銀行、Nike 或奇異公司的價值還高

Now, what caused this huge slide?

究竟是什麼原因造成這次的下跌呢？

Well, Facebook reported disappointing earnings on Wednesday evening.

星期三傍晚，臉書發布了收入數據，而數字不是很理想

Facebook has had a good run for a long time,

長久以來，臉書的營運狀況一直很好，

and its shares actually hit a record leading up to the earnings.

股價確實打破紀錄，利潤也隨之而來

But on the call and in the numbers,

但在眾人呼聲和數據之下，

Facebook revealed that its user growth numbers are slowing in every major region.

臉書透露，所有主要地區的使用者數目成長率正趨於平緩

And its revenue per user is also slowing.

每用戶的收入也是緩慢成長中

Now, it's important to remember that Facebook is still a very profitable company.

但要記得，臉書依然是獲利非常高的公司

It still has margins that would be the envy of almost every other company in the world.

它的融資仍讓幾乎所有全球其他企業眼紅

But when people had been projecting that this growth rate would continue almost indefinitely,

可是當人們都預估這長紅景象會持續時，

this came as a very nasty surprise to investors.

這次公布的數字讓投資人大吃一驚

And that's why they panicked yesterday evening

這也是為什麼昨天傍晚他們恐慌了

and pushed the shares out dramatically,

並突然拋售股權，

and it's extended into the morning.

一直到隔天早上

Analysts and investors say that this is partially a reflection of just how extended Facebook's shares had become leading into the earnings.

股票分析師和投資人表示，這次事件只是部分反映臉書的股價浮動長期影響利潤多寡

And they stress that actually Facebook is still a company that is growing at a healthy clip.

他們也強調，臉書仍然是穩定成長的公司

And this is a healthy correction for a company.

這次股價的變動對公司是有益的

However, this is clearly a reminder that Facebook is still under pressure on many fronts.

然而，這也代表臉書仍受許多方面的因素影響

Its user growth is slowing.

像是使用者數目成長趨緩

It's facing more regulatory scrutiny after the Cambridge Analytica scandal that erupted in early March.

在三月初爆發的劍橋分析公司醜聞之後，臉書開始面對更多例行性的監視、審查

Until those clouds dissipate,

在疑雲消散前，

investors are going to be very wary of dipping back into the social media giant's stocks.

投資人對於購回該公司的股權，態度上會比較保守
