How Much Can You Earn With the Vanguard S&P 500 ETF (VOO) If You Invest $100 per Month Starting Today? Here's What History Suggests.

No direct fundamental catalyst here; the investable effect is flow psychology. Content that reiterates long-run S&P compounding tends to reinforce default allocations into cap-weighted passive products, which mechanically supports the largest liquid names and leaves smaller, less-indexed equities without a bid. That is modestly constructive for NVDA and NFLX as index-adjacent momentum leaders, but it is not enough by itself to justify chasing either name today; GETY and MTAKU have essentially no linkage absent company-specific news.

Time horizon matters: over the next few days this is noise, but over 1-3 months repeated "buy the index" messaging can keep retail dollars anchored in SPY/VOO/IVV and prolong megacap leadership after any dip. The key reversal is a breadth regime change: falling rates, improving small-cap earnings revisions, or a volatility shock that forces de-risking from passive vehicles and rotates money into equal-weight or cyclical exposure.

Contrarianly, the article’s backward-looking return math likely overstates forward expectations from current index concentrations and valuation levels. The better trade framing is not "S&P up 10%" but "cap-weighted index may continue to outperform equal-weight if earnings remain concentrated in a handful of mega-caps." If breadth broadens, that edge disappears quickly.
