If you believe DLR’s premium margins and conservative balance sheet deserve a higher multiple than the DCF range implies, then hold or add selectively because its profitability profile is clearly stronger than CIEN’s; if you believe cash-flow valuation should dominate, then be cautious because the current price is far above the DCF band.
DLR’s current price of $188.52 is far below CIEN-implied price of $1,588.05 based on P/E, implying a 742.4% upside in this framework. However, CIEN set looks noisy because DLR and CIEN trade on very different earnings bases, and the P/E gap is not matched by the much tighter P/S and EV/Revenue comparison.
