Cantor Fitzgerald analyst Brian White believe today's renewed selloff in Tableau could be driven by profit taking by investors that purchased the stock near yesterday's post-earnings lows, "aftershock" selling by previous holders and technical factors. White, who said yesterday that Tableau's story remains "very positive" and called the selloff then a "rare" buying opportunity, said today that he views the pullback in shares as another opportunity. White keeps a Buy rating and $162 price target on Tableau shares, which are down $5.51 to $107.99 in morning trading.
