Elon Musk is the most influential celebrity in the stock market

The investing experts at money.co.uk found that leading entrepreneur Elon Musk has caused the most change on the stock market by a landslide. Not only is he the most vocal about other companies on social media, his tweets have caused huge differences to share prices as investors take his word as golden.

The Tesla CEO has caused a huge impact, with one tweet causing over 1000%+ difference to the company’s value. The study found that Elon Musk caused an 84% average change to share prices of the companies he mentioned based on 17 tweets. His influence can be seen recently even outside the stock market, with tweets seeing Bitcoin first soar, then plummet and Dogecoin surge following his announcements on Tesla accepting and then rejecting different cryptocurrencies as forms of payment.

Oprah Winfrey caused a 23% change to a company’s share price from just one tweet

Oprah Winfrey, a famous talk show host, entrepreneur and author, is another influential celebrity affecting the stock market with her tweets. As an official spokesperson for Weight Watchers, Winfrey made a huge impact in January 2016 for the brand as she tweeted “Eat bread. Lose weight. Whaaatttt? #ComeJoinMe” leading to an impressive 23% change to the company's stock price. Investors clearly saw her involvement with the brand as a reason to grab a slice of the action.

Outspoken Kanye West is the third most influential celebrity on Twitter

Taking third place as the most influential celebrity is outspoken artist Kanye West. Known for sharing his thoughts and opinions freely, the singer historically caused a 23% change to the stock market just from one tweet. 

The tweet in question caused GAP stock to soar as Kanye announced a new collaboration with his fashion brand Yeezy, putting the US apparel company officially back on the map - and in a strong position within the market.

Justin Bieber ranks among the top 5 most influential celebrities 

Justin Bieber, the teen idol turned singing sensation has been at the center of numerous scandals, but that hasn’t negatively impacted his influence of opinion - even in finance.

But it’s fashion where Bieber caused a stir. After sharing a post from his personal Instagram of a picture of Crocs with the caption “Soon.”, this led to a nice bump for the controversial shoe, boosting Crocs’ shares by 7.6%.

Kylie Jenner caused a Snapchat slump

Kylie Jenner also made headlines in 2018 for tweeting about not wanting to use Snapchat any more. This simple diss of the brand led to an immediate drop of 7% to the company stock price, after many users and investors turned away from the brand following Jenner’s disapproval.

His most impactful tweet of all time caused an incredible 1098% change to stock price. The simple tweet ‘Use Signal’ which the SpaceX chief executive officer (CEO) tweeted on January 7th was followed by the huge jump in stock price. The tweet originated following questions over Whatsapp privacy concerns, which prompted millions of users to switch their accounts to Signal causing a huge shift in the market. 

#2 Gamestop

He also caused a 352% change in the gaming industry as he fueled the frenzied surge in GameStop shares. On the 26th of January Musk tweeted “Gamestonk!!”. This made-up word is a combination of GameStop and “stonks,” which is a slang term for stocks - intensifying the surge in stocks which has become known as the biggest investment story of 2021.

#3 Tesla

Musk doesn’t only cause positive changes in the market either, as advisors are becoming concerned about his high influence in this space. He caused an 11% decline to his own company in 2018 when he tweeted in response to a poor performance report, where Musk said that they are looking long term for their growth rather than immediate growth. After admitting he was happy to lose money at the moment with growth around the corner, the brand’s stock dropped by 11%.
