** Bernstein initiates Aditya Birla Lifestyle Brands AITT.NS with "market-perform" at PT of 170 rupees
** Says co's legacy brands - Louis Philippe, Allen Solly and Van Heusen - have strong brand recall, profitability but competition, "casualisation" trend may limit long-term growth
** Adds co could see high competitive intensity in wedding and casual wear segments, even though they are fast growing
** Stock gains 0.7% to 156.25; set to snap three-session losing streak
** Bernstein remains on the fence about whether efforts on product and branding can lead to double-digit pct growth in medium term
** AITT falls 1.4% since trading debut in June post spin-off from Aditya Birla Fashion and Retail (ABFRL) ADIA.NS
