Diamondback Energy downgraded to Buy after 40% rally; strong Q1 results but risks remain.

Diamondback Energy (FANG) has been downgraded to a Buy rating after its stock surged about 40%. The company reported strong first-quarter results, raised its production guidance, plans to accelerate debt reduction, and increased dividends and buybacks. However, macroeconomic risks such as the Iran conflict and potential inflation shocks suggest investors should be cautious. Despite the rally, the stock's intrinsic value remains above current levels under conservative estimates, but the risk-reward balance is less attractive than before.
