The S&P 500 closed at its highest level on record, @KobeissiLetter reported. 2% since the March 30th bottom, which marked the low point for the S&P 500 in the recent period. That rebound has produced a gain of $10 trillion in market capitalization for the S&P 500 in just 29 trading days.

The same $10 trillion increase in market capitalization has occurred since the March 30th bottom. The speed of the advance stands out even by the standards of recent bull markets, compressing what often takes months or years of gains into less than six weeks of trading. March 30th served as the starting point for the measured recovery.

From that session forward, the index has added value at an average pace that few historical rallies have matched in such a compressed window. The record close comes as market participants continue to digest the implications of the swift recovery. No single catalyst was isolated in the reporting, but the scale of the move has drawn attention across trading floors and investment committees alike.

@KobeissiLetter reported the figures without attributing them to any specific bank or research house. 2 percent advance from the March 30th bottom, and a $10 trillion expansion in market capitalization over 29 trading days.
