Market Cap Plummets by 1 Trillion Won in a Day: U.S. Growth Stocks Hit by Sell-Off

HubSpot Inc. (HUBS) plunged 5.33% on January 16 in New York trading, closing at $311.88. Volume exceeded its norm, wiping out roughly $830 million in market capitalization—about ₩1 trillion—in a single day and reducing its total market cap to approximately $16.3 billion (around ₩21 trillion).

Shares gapped down sharply at the open, falling as low as $309, and are now trading more than 60% below their 52-week high of $881.

Investor sentiment remains muted after Oppenheimer warned of weak new recurring revenue from key partners in Q4 and forecast slower growth in 2026, and Weiss Ratings assigned the stock a lowest-tier “E” grade with a sell recommendation earlier this month.

Despite this, the average 12-month price target among roughly 30 Wall Street analysts sits near $576, implying about 80% upside from current levels.

HubSpot is a high-growth software company offering cloud-based CRM and marketing and sales automation solutions on a subscription basis to small and midsize businesses. Its Q2 FY2025 revenue rose 19% year-over-year.

At its Fall 2025 event, the company unveiled more than 200 new products—including a data hub and AI agents—underscoring its strategic shift toward a customer platform where humans and AI collaborate.
