** Shares of B2B travel services firm WEB Travel WEB.AX slips 1.8% to A$4.5, their lowest level since July 8
** Jefferies flags Spanish peer HBX Group HBX.MC downgrading full-year guidance as a result of the macroeconomic backdrop and weaker U.S. dollar
** Brokerage says WEB is not immune to the same factors impacting HBX's Q3 results
** Adds, although WEB's total transaction value (TTV) growth surpasses HBX, HBX seems to outperform WEB regarding take rate and EBITDA margins
