** BofA Global Research downgrades rating on both the stocks to "neutral" from "buy"

** Research firm cuts LEA price objective to $123 from $135, still an upside of 10.8% from the stocks last close

** However, lifts BWA PO to $46 from $41, representing a 5.3% premium from last close

** BofA says BWA's stock has seen several upgrades recently and is now trading near its typical valuation range, but with limited growth expected next year, further upside depends on financial turnaround that may not materialize until 2027

** Notes although LEA is trading below its historical valuation, ongoing challenges in the auto industry and weak production trends limit its ability to achieve meaningful growth
