Optimist Fund stated the following regarding Monday.com Ltd. (NASDAQ:MNDY) in its fourth quarter 2025 investor letter:
“Monday.com Ltd. (NASDAQ:MNDY) – In November, Monday.com reported a mixed quarter, with revenue and free cash flow growing approximately 26% and 10% year over year, respectively. Enterprise performance continued to accelerate, while growth in small and mid sized customers further decelerated.
We held the position through year end and into 2026, believing management could execute against the objectives they had outlined, supported by a strong historical track record. However, following the company’s fourth quarter earnings release earlier this week, we have fully exited the position. The reported results were not aligned with our forecasts, and more importantly, management was unable to clearly articulate what is occurring within the business.
When we lose confidence in the accuracy or clarity of management’s communication, we exit. That is what we have done here.”
