According to @StockMKTNewz, the Magnificent 7 represent 44.9% of the NASDAQ 100, so a $10,000 allocation embeds about $4,490 of exposure to that cohort, underscoring high index concentration risk; source: @StockMKTNewz. For trading, sizing hedges or factor tilts around a 44.9% weight can help manage NASDAQ 100 P&L sensitivity to mega-cap moves, as index performance will be disproportionately affected by that group; source: @StockMKTNewz. Crypto-focused desks using the NASDAQ 100 as a risk-on gauge should account for this concentration when interpreting equity-led signals into BTC and ETH sentiment; source: @StockMKTNewz.
