Known for his noticed posts on the social network Twitter, the boss of Tesla and SpaceX Elon Musk recently caused uncontrolled increases in the share prices of some companies.
Latest example: the Etsy Tuesday online shopping site ... thanks to one of the richest man's dogs in the world.
His tweets have not finished panicking the American stock market.
On Tuesday, a few words from Elon Musk, the boss of electric car maker Tesla and space flight specialist SpaceX, on the social network were enough to cause the stock price of the online sales site Etsy to soar.
In his message, the entrepreneur simply writes that he likes the American site.
Almost instantaneously, Etsy's share price rose, opening 18% higher than when it closed on Wall Street.
If the event might seem anecdotal, it is not an isolated case.
I kinda love Etsy

The maddening case of Signal
It is even starting to become a habit.
The latest spectacular example: two weeks ago, Elon Musk encouraged the 43 million people who follow his Twitter account to use the Signal encrypted messaging app.
In a few minutes, the course had taken 1000%!
Problem: the company affected by this increase was in fact Signal Advance, a Texan company which did not understand why its value was suddenly multiplied by 12 ...
Use Signal

For Etsy, the effect has been less dramatic.
After an opening up sharply, the price returned to its usual level.
But investment bank Jefferies still raised Etsy's stock by $ 40.
All thanks ... to one of Elon Musk's dogs.
Indeed, it was after buying a hand-knitted woolen beanie for one of them that the Tesla boss tweeted his satisfaction.

The Japanese video game company Bandai Namco also benefited from a 4% jump on the Tokyo Stock Exchange thanks to Elon Musk.
It was 10 days ago.
Whoever became the richest man in the world then simply posted the image of a gaming character in a tweet.
