What would change the picture for MPWR

These are the specific events and levels to watch. None of them is a prediction.

• The Oct. 29, 2026 earnings report is 0 days away. Monolithic Power Systems, Inc. beat estimates in 3 of the last 4 quarters (average surprise +3.4%); a miss would break that pattern.
• Insider buying: none on the open market in 90 days. A purchase by an executive or director would be the first in at least three months. It would appear on SEC Form 4 within two business days.
• Analyst ratings: the average score moved from 4.2 to 4.13 over three months. That is on a scale where 5 is strong buy and 1 is strong sell. A run of downgrades after earnings usually shows up here first.
• Price levels: a close above $1684.95 would be a new 52-week high, 40.6% above the latest close of $1198.81. A close below $851.43 would be a new 52-week low, 29.0% below it.
• Growth: revenue rose 28.7% year over year in the quarter ending Jun 2026 (trend: accelerating). At a P/E of 73.2, a slowdown would matter more than at a lower multiple.
• New shares: dilution risk is low now. A new shelf registration (S-3) or prospectus supplement (424B) for an offering would raise it.
