Shares of Weight Watchers International Inc. surged to an all-time high Tuesday, after J.P. Morgan started coverage of the weight management and wellness company with a bullish “overweight” rating.

J.P. Morgan analysts set a price target of $105, which was 14% above current levels, saying it was time to “stop watching from the sidelines.”

The stock US:WTW ran up 5.6% to a record close of $91.74. The stock hit an intraday record of $93.92 early in the session.

“Following three years of double-digit revenue and earnings pressure through 2015, management stabilized the trajectory, repositioning the company for outsized growth by revamping its points program, significantly improving the mobile platform, and recruiting pivotal social media influencers,” J.P. Morgan analysts wrote in a note to clients.

By social media influencers, the analysts were referring to Oprah Winfrey, who has 42.6 million Twitter followers.

After closing at a record low of $3.75 in July 2015, the stock started shooting higher in October of that year, after the company said Oprah bought about 6.4 million shares, or 10% of the shares outstanding.

Although the stock has already performed “extremely well” this year, J.P. Morgan analysts said they expect “continued upside driven by positive earnings revisions and multiple expansion as investors gain comfort around the sustainability of [Weight Watchers’] growth story.”

They see a “clear path to over $2 billion in revenue by 2020, compared with $1.31 billion in 2017 and the FactSet consensus of $1.57 billion for 2018.

Analysts are also impressed by how the company’s free cash flow generation model has enabled the company to materially improve its balance sheet, with plans for leverage ratios to fall by the end of 2018 to less than half what they were in 2015.

“Beyond the potential for tuck-in acquisitions to support their tech platform, we also see an opportunity for [Weight Watchers] to reinstate its dividend in the outyears given the consistency of the company’s model,” analysts wrote.
