S&P 500 just closed at a new all-time high, up 3.6% this week.

That's $2.5 trillion in market cap added in five days.

To put that in perspective: the entire crypto market is around $3 trillion. We just added nearly that much to U.S. stocks in one week.

This kind of move usually comes from either a major risk-off relief rally or fresh optimism on earnings/Fed policy. Either way, it's a reminder that when the tape is strong, it's really strong.

Watch for whether breadth confirms this or if it's just mega-caps doing the heavy lifting again.
