The S&P 500 experienced the largest single-day reversal in stock market history, largely attributed to a presidential announcement of a 90-day pause on specific tariffs. This significant market pump is also fueled by speculation about undisclosed outcomes from an emergency Federal Reserve meeting, raising concerns about its sustainability as a potential bull trap.

The S&P 500 recorded the largest single-day upward reversal in stock market history, making it a historic day for the market.
Donald Trump announced a significant tariff increase on China, raising tariffs to 125%, which would drastically increase costs for Chinese goods, but also declared a 90-day pause on reciprocal tariffs for countries willing to negotiate.
The trade war situation with China remains unresolved, as both the US and China continue to increase tariffs on each other, although other nations like Europe, Taiwan, Japan, and India are seeking negotiation.
The 90-day tariff pause may not fully justify the $5.5 trillion influx into the US stock market, suggesting the current market pump could be a significant bull trap given the unresolved trade war.
An emergency Federal Reserve board meeting was held on April 7th, and the market might be pricing in insider information about potential rate cuts or quantitative easing, even though the meeting details have not been publicly disclosed.
China announced direct market stimulation by buying a substantial amount of assets from its own stock market, injecting liquidity into its economy.
Previous trading gains were largely lost due to market volatility, with a Bitcoin long position stopping out at break-even and other positions incurring significant losses, reducing the account back to its initial capital.

The sustainability of the historic market pump remains uncertain until the Federal Reserve's decisions from its emergency meeting are revealed, suggesting a potential bull trap.
