NVIDIA just announced the biggest buyback in corporate history.

$150B added to their buyback program. Total authorization now at $235B through Jan 2028. That's ~$14B/month they'll be buying their own stock.

For context: Apple's previous record was $110B in 2024. NVIDIA just doubled it.

Why this matters for markets:

$NVDA is now ~7% of the $SPX. That's bigger than entire sectors like energy or utilities. The top 10 stocks = 40% of the index. Historic concentration.

Every $100 into $SPX, $40 goes to just 10 names.

The divergence is insane:
$SPX near ATH
Equal-weight $SPX at 3-month lows

Translation: Big Tech (led by $NVDA) is carrying the entire market. When one company has this much weight, their buyback isn't just bullish for them - it props up the whole index.

$NVDA basically saying "our stock is cheap" while simultaneously becoming the liquidity anchor for equities. This is how you engineer a rally in 2025.
