The 30-second take

Tech megacaps drive index performance — the 'Magnificent Seven' make up roughly 30% of index weight. When the cap-weighted S&P diverges from the equal-weighted version, that's the concentration-risk talking point. Compare against the FTSE 100 (different sector composition) and the Nasdaq 100 (the high-beta version). At interview, don't just quote the level — quote the trend, the driver, and one sector stand-out.
