So what

We can attribute Alteryx stock's strong performance last month largely to the company's Oct. 31 release of third-quarter results that demolished Wall Street's earnings estimate. Shares popped 8.5% the following day and continued to move higher throughout the month. 

In Q3, Alteryx's revenue soared 65% year over year to $103.4 million. Revenue growth was driven by a 30% increase in customers to 5,613 customers at the end of the quarter and a dollar-based net expansion rate of 132%. That means that the average existing customer spent 32% more in the quarter than they did in the year-ago period.

As is quite common for a relatively new public tech company (it had its IPO in 2017), Alteryx isn't consistently profitable under GAAP (generally accepted accounting principles). However, it is profitable from a non-GAAP, or adjusted, standpoint. It posted a GAAP net loss of $6.2 million, or $0.10 per share, versus net income of $10.8 million, or $0.17 per share, in the year-ago period. Its adjusted net income came in at $16.4 million, or $0.24 per share, up from $11.9 million, or $0.18 per share, in the third quarter of last year. This result crushed the analyst consensus estimate of $0.09.

Now what

Alteryx's management guided for fourth-quarter revenue of $128 million to $131 million, which represents an increase of 44% to 47% year over year. It also forecast adjusted earnings per share of $0.27 to $0.30.
