Viewers of Netflix’s new romantic comedy, “To All the Boys I’ve Loved Before,’’ have noticed the main character’s sister, played by Amy Cathhcart, drinking a yogurt out of a distinctive little bottle, and are talking about it on Twitter, according to Mark Bachman, head of M Science’s TickerTags, a research firm that analyses the relationship between social media and a company’s performance.

In the movie, the drink is called a “Korean yogurt smoothie,’’ but audiences have clearly spotted Yakult’s “distinct red foil top,” Bachman said in a note to clients on Friday.

“While the brand is of Japanese origin and was never mentioned by name in the movie, it is clearly a Yakult bottle, which Twitter users quickly noticed,” he said.

Yakult’s “mention frequency” spiked after the release of the Netflix movie and a majority of the conversations were directly related to interest in the product, according to the note. Shares of the stock, which have dropped about 6 percent this year amid slower sales growth, climbed more than 2.6% since the movie was released on Aug. 17. About half of that rally came today with a 1.7% gain.
