Starbucks Corp's recent weeks have been fraught with turmoil, as a combination of boycotts, staff strikes, and a lukewarm holiday promotion led to a $10.98 billion decline in market value.

While the iconic coffee chain's struggles are multi-faceted, including a less cheerful Red Cup Day and global political tensions spilling into its cafes, the undercurrent of discontent signals a challenging brew for the company's future, an industry analyst has said.

The stock market has weighed heavily on Starbucks as it grapples with complex societal issues, prompting investors to retreat and driving its shares into their longest losing streak since its 1992 initial public offering. Within the span of 19 calendar-days, since its November 16 Red Cup Day promotion, shares of Starbucks have plummeted 8.96 percent, which equates to a nearly $11 billion loss, amidst analysts' reports of slowing sales and a subdued response to the holiday season's offerings.

The boycotts at the Seattle, Washington-based chain have deep roots, touching on sensitive geopolitical issues after the company found itself in hot water following a tweet from Starbucks Workers United, the union representing many of its baristas, expressing solidarity with Palestinians.
