Why are US 25% semiconductor tariffs moving the Nasdaq 100 today?

Chips power data centres, PCs, and phones. Higher tariffs lift input costs and uncertainty for hardware-heavy megacaps inside the Nasdaq 100. Funds reprice earnings quality, margins, and delivery schedules, which can widen trading ranges. That is why semiconductors and Big Tech stocks often set the index’s direction on tariff headlines.

What sectors could hold up better if chip costs rise?

Software, digital ads, and services have less direct hardware exposure, so margins can be steadier. Some fabless designers with flexible sourcing may also fare better than device assemblers. Investors often rotate toward recurring revenue and high free cash flow while US 25% semiconductor tariffs cloud hardware demand and pricing.

How should Canadian investors adjust their Nasdaq 100 exposure?

Check ETF structure and currency. Hedged funds like ZQQ, XQQ, and HXQ reduce USD swings, while ZNQ keeps USD exposure. Rebalance gradualy, trim concentrated hardware bets, and add in steps near support levels. Keep cash for opportunities if volatility rises as companies update guidance on costs and lead times.

What index levels are useful for planning entries?

Watch the 50-day average near 25,336 and the Bollinger middle band around 25,393 as near support and resistance. The lower band near 24,840 can mark deeper tests. These are guideposts, not guarantees, and can shift. Plan entries and stops around them rather than trying to predict short-term moves.

Could companies pass tariffs to customers without hurting demand?

Some can, but it depends on product and competition. Passing costs through can protect margins but risks lower unit demand. Absorbing costs can preserve demand but compress margins. Most will try a mix while they reroute supply, negotiate with partners, and adjust product mix to reduce tariff exposure.
