TDG Analyst Notes Highlight Valuation Concerns. Recent analyst commentary suggests TransDigm may be undervalued, with one source estimating a 23% discount to its current price. RBC Capital kept its sector rating but lowered its price target to $1,200, reflecting a more cautious outlook. A Seeking Alpha piece noted that the stock’s price dynamics are drawing more attention than broader AI themes. These observations come as the shares trade near the $1,219 support level.
