Apple’s Nine-Week Win Streak Delivers 7.5% Gain, Drives 45.8% ETF Weight
AAPL•Apple extended a nine-week winning streak, its sixth such run, and averaged a 7.5% gain over the next four weeks, outperforming the S&P 500 in four of those instances. The stock represents 45.8% of Vanguard’s Mega Cap Growth ETF and is a key driver of a rally concentrated in AI-linked mega caps, raising valuation concerns.
1. Apple’s Nine-Week Win Streak
Apple has just completed a nine-week consecutive gain, marking one of only six such streaks in its trading history. Previous nine-week streaks produced an average 7.5% return over the following four weeks, outperforming the broader market in four out of five occurrences.
2. Performance Versus the S&P 500
Over the most recent nine-week streak, Apple’s forward four-week returns outpaced the S&P 500 by an average of 8.3 percentage points. Historical data shows that three out of five past streaks delivered at least 10% gains in the first month, though those occurred during Apple’s early growth phase.
3. ETF Concentration and Market Leadership
Apple constitutes 45.8% of the top four holdings in Vanguard’s Mega Cap Growth ETF, underscoring its influence on fund performance. Its size and AI-driven momentum alongside peers like Nvidia and Alphabet have concentrated market gains within a small subset of mega caps.
4. Valuation and Risk Considerations
The rally’s narrow breadth has stretched Apple’s valuation metrics above historical norms, prompting concerns of profit-taking or sector rotation. Investors should monitor whether sentiment shifts or broader market corrections curtail further upside for mega-cap leaders.
