The euro got slammed today after European Central Bank President Mario Draghi indicated he is watching the level of the currency and may have to reevaluate what a higher level does to inflation.
Today's tumult came just days after the euro slid on worries about political uncertainty in Spain and Italy, and it's leading investors to wonder if the bull run in the currency is coming to an end.
Todd Gordon is not particularly worried.
Gordon, the founder of TradingAnalysis.com, says the euro's fall was "in the charts." He told CNBC's Scott Wapner that the S&P 500 stock index had been moving in tandem with the German DAX index - but the DAX has been weakening recently, and "that's starting to precipitate a little risk-off tone here."
