$LITE falls 4.3% in a day, and the price returns to 864.6. This is not just a sector rotation. It’s the direct pricing of tariff policy expectations in semiconductor TradFi perps. A single source shows that the Tax Foundation estimates that the Trump administration’s tariffs will reduce the United States’ long-term GDP by 0.4% and cut roughly 345,000 full-time jobs. As macro growth expectations contract, the first pressure falls on sectors like technology and semiconductors—highly sensitive to global supply chains and capital expenditures.

The transmission chain is clear: tariffs raise import costs, putting pressure on corporate profits and investment appetite. Even though rate expectations may drift lower due to slower growth, earnings expectations on the numerator side are likely to be revised down even faster. As $LITE represents a semiconductor ETF, its decline directly reflects the market’s forward pricing of damage to this part of the real economy. When policy uncertainty dominates, capital tends to rotate out of high-beta tech stocks into more defensive sectors.

For me, this is a left-side observational window based on a single signal. If tariff details are released later and the impact exceeds expectations, selling pressure on the semiconductor sector could persist. In terms of execution, I won’t try to bottom-fish here, but I will closely watch whether the price breaks the key psychological level at 850—if it does, that would confirm the reinforcement of the downtrend.
