Frequently Asked Questions
Why is AMD stock down this week?
AMD shares fell 2.03% to $608.10 in the latest session, even as the broader market gained. The article notes that the decline gives patient investors a pullback to study rather than a breakout to chase. Investors should also weigh the risk that AMD's unconditional purchase commitments, which rose to about $30 billion by late June from roughly $12 billion at the end of 2025, are fixed obligations if AI chip demand slows.
What is AMD's plan for supply in 2027?
CEO Lisa Su said AMD plans to substantially increase its supply in 2027. Bulls argue that today's supply crunch can become tomorrow's revenue capacity. The main risk is that the company is committing large sums in advance, so if AI chip demand cools while capacity expands, the balance sheet could absorb the strain. Investors should monitor demand trends alongside the company's capacity plans.
Are Apple's iPhone 18 sales strong so far?</question>
The early iPhone 18 cycle is giving mixed signals. Analyst Gene Munster said Pro lead times are 31% shorter than the iPhone 17 Pro at the same point last year and called the cycle off to a solid start. Counterpoint Research reported that iPhone 18 Pro series sales grew 12% year over year in the first three days. Estimates for the iPhone Duo's first-year units are also rising, from about 10 million to close to 20 million.
Should investors buy QQQ or IWM for broad market exposure?
QQQ tracks the Nasdaq 100, which closed at 30,883.15 points, up 0.51%, and offers concentrated exposure to large technology names. IWM tracks small-cap stocks and offers broader exposure to companies outside the largest index constituents. With the VIX at 14.84, calm market conditions favor selective positioning. Investors should compare each ETF's sector mix, risk level, and time horizon before choosing between them or holding both.
