The damage arrived inside an hour. Shares touched $381.81 before the news landed. They bottomed at $355.16 after it. That is a swing of almost 7% in one session.
The stock later steadied near $360.71, down 3.9% from Tuesday's close of $375.35. Alphabet is worth $4.61 trillion. Wednesday's slide erased close to $190 billion of that. At the low the figure was nearer $260 billion.
The stock still trades about 11% below its 52-week high of $404.47.
