** Shares of Dutch lighting company Signify LIGHT.AS fall more than 10%, driven by concerns over its lack of a clear growth trajectory after declining Q2 performance marred by currency headwinds
** Signify's Q2 sales fall 4.4% y/y to 1.42 bln euros ($1.67 bln), weighed down by a 3% currency exchange hit from weak U.S. dollar and Chinese yuan
** "Signify lacks a growth story as it has seen positive organic growth only twice in the last eight years amid a transition to LEDs and deflation in the supply chain," J.P. Morgan says
** Degroof Petercam highlights weak visibility, and lack of growth and margin improvement
** "Returning to top line growth is in our view still too ambitions in the current environment with ongoing economic uncertainty," the broker says
** The shares, which up to previous session's close were up 6.6% YTD, are one track for their worst day in three months
