** Shares of auto parts supplier Dorman Products DORM.O rise nearly 1% to about $153 in early trading, after Stephens initiates co with "overweight" rating, PT at $185

** PT represents a 22.8% upside on stock's last close

** Brokerage says DORM's ability to identify and supply parts which have poor substitutes in the market is beneficial to both sales and gross margins

** "As tariffs and inflation make vehicles expensive and less affordable, the non-discretionary and "break fix" nature of DORM's products provide them with a fair amount of price/demand inelasticity," brokerage says

** Seven of eight brokerages rate the stock "buy" or higher, and one "hold"; their median PT is $176.5 - according to data compiled by LSEG

** Including session moves, shares up about 19% YTD
