Possible reason for the accelerated drop today.
Analyst Actions: Goldman Sachs Downgrades Alteryx to Neutral From Buy
I did not see their price target but Alteryx’s average rating among analysts is a buy, with an average price target of $22.
I added some today.
Downgrade AYX, but increase the target price to 29 from 26.
Really funny

Yeh they’re probably telling customers to sell whilst they buy at better prices - in a few months once they have a position they will probably upgrade. I either ignore Goldman for the most part or take them as a contrarian indicator.
