BUZZ-Datawatch Corp: Biggest single-day gain in a year
** Enterprise data analytics software maker's shares up 17 pct at $13.95, biggest intra-day percentage jump in a year
** Third-quarter revenue beats the average analyst estimate by 1.3 percent, helped by higher sales of its visual data discovery product
** "Recent integration of DWCH's visualization tech with Informatica Corp, Pivotal Therapeutics Inc and Amazon.com Inc (Kinesis) could spur additional demand," Cowen & Co analysts wrote in a note
** Stock fell about 42 percent up to Wednesday close since April, when the company had estimated weak second-quarter results
** "We believe these results support our prior belief that the F2Q shortfall was mainly due to M&A integration issues as opposed to any meaningful shift in end-market demand," analysts added
