** Morningstar initiates coverage on Australia's Dalrymple Bay Infrastructure DBI.AX with a Wide Economic Moat rating and a fair value estimate of A$4.60
** Highlights cost advantage company enjoys in servicing nearby coal mines as they pay lower rail transport costs to reach DBI's terminal compared to other, more distant terminals
** Investment research firm expects relatively strong earnings growth in the medium term as terminal charges lift with inflation and to recoup elevated capital expenditure
** But says company is overvalued because of longer-term headwinds; fair value estimate is lower than Monday's close
** Six of eight analysts rate the stock "buy" or higher and two "hold"; their median price target is A$5.63, as per data compiled by LSEG
** Stock is up 9.8% YTD, as of last close at A$5.50
