Been watching ON Semiconductor's chart and honestly, it's been brutal. Down 43% over the past six months while the broader tech sector only fell 5.9%. Even other semiconductor names like NXP, Analog Devices and Magnachip held up better - they lost around 14-24% in the same period. So why are semiconductor stocks down across the board, and why is ON getting hit especially hard?

Looking at their latest numbers, the story becomes pretty clear. Power Solutions revenue dropped 16% year-over-year in Q4 2024, and Analog and Mixed-Signal got absolutely hammered with an 18% decline. Even their Intelligent Sensing Group, which showed the most resilience, still fell 2%. All told, that's a 15% overall revenue contraction. Not pretty.

The automotive sector is where things get really messy for them. Geopolitical tensions, supply chain chaos, and the EV adoption rate coming in way slower than expected - all of this is creating serious demand headwinds. They're expecting automotive revenues to drop 25% or more sequentially in Q1 2025, mostly due to weakness in China. That's the kind of guidance that makes investors nervous.

The analyst consensus has been getting worse too. Q2 2025 earnings estimates are sitting at 53 cents per share, down 7% in just the last month. Revenue for that quarter is expected at $1.43 billion, which would be 17.57% lower than the year-ago period. For the full year 2025, they're looking at $6.07 billion in revenue - a 14.3% decline - with earnings per share at $2.49, down 37% year-over-year.

It's a tough position. The macro environment isn't helping, and why semiconductor stocks are struggling right now comes down to demand destruction across multiple segments. That said, ON's long-term bet on silicon carbide and positioning in higher-growth markets could eventually pay off if they execute. But for now, near-term recovery looks uncertain at best. The company's currently ranked as a Strong Sell, so plenty of investors are staying on the sidelines until we see some stabilization.
