The Last Time This Happened, Stocks Tumbled 20%

For the last 11 weeks - off The Dimon Bottom - the S&P 500 has made higher lows week after week without break. Last week, however, saw the streak end (with a lower low set). This length of incessant "uptrend" streak has not been since February 2011, at which time it was broken leading to an immediate decline followed by a considerably plunge soon after...

Couldn't happen again?

 

In 2011, the S&P 500 fell 4.8% in the month after the trend was broken... and then a 20% decline into the fall of 2011.

While we are sure it's different this time, between "Brexit" and the Election there are plenty of catalysts for 'uncertainty' however.
