US stock markets have seen a significant reversal of gains made since the election of Donald Trump. The S&P 500 has wiped out nearly all its post-election gains, with some reports indicating that about half of the 'Trump bump' is gone. The NASDAQ 100 is also close to losing its entire post-election bump, having already reversed more than the election spike and is less than a couple hundred points away from giving up all gains. The $SPY has similarly given back all gains since the day after the election. Additionally, the S&P 500 post-election rally has already lost a third of its gains.
