NEW YORK (BLOOMBERG) – Etsy shares jumped on Tuesday (Jan 26) after the e-commerce company earned praise from Elon Musk, the third time this month that the Tesla Inc. leader drove up a stock with the push of a social media button.

“I kinda love Etsy,” Tesla’s chief executive officer wrote in a tweet. In a follow-up post, Mr Musk explained that he had “bought a hand knit wool Marvin the Martian helm (sic) for my dog” and posted a picture of it. Shares gained as much as 8.6 per cent and hit an intraday record.

Etsy’s jump comes after hoards of day traders have piled into hot stocks like GameStop and Express, causing both to soar since the beginning of the year. Musk is a favourite of many of those who exchange ideas on Reddit message boards.

After US markets closed on Tuesday, Mr Musk weeted about gaming retailer GameStop and the Reddit message board that is behind the big push higher, and its shares jumped more than 50 per cent in after-hours trading.

Earlier this month, Signal Advance skyrocketed after Mr Musk urged in a tweet for his followers to “use Signal.” That spurred ticker confusion among traders who bought shares in the medical-device provider instead of the closely held nonprofit Signal messaging app.

Separately on Tuesday, Jefferies raised its price target on Etsy to US$245 from US$205, writing that gross merchandise sales growth at the company “continues to outpace broader e-commerce.” Jefferies has a buy rating on the stock, and wrote that there was a “long runway to add buyers.”

Etsy has been among the standout performers of the past several months. The stock is up about 600 per cent off a March low, with most of the gains reflecting increased e-commerce demand in the pandemic.
