I should probably keep my mouth shut because I don't want to jinx it, but the Diageo (LSE: DGE) share price is finally showing signs of life. Sales suddenly slumped in Latin America and the Caribbean, then the weakness spread to bigger markets including the US and China, as inflation surged and the cost-of-living crisis went global. As sales stalled and full-year operating profits slipped, Diageo's net debt suddenly looked far more worrying too. Like I said, I don't want to make too much of this, but the Diageo share price has suddenly climbed 12.5% over the last month. Can Diageo shares keep fizzing along?
