BENGALURU (Reuters) -Shares of Wipro slid almost 3% on Friday, a day after long-serving CFO Jatin Dalal resigned in a surprise move, the latest senior level exit at the fourth-largest Indian IT services provider. Dalal's exit follows those of Chief Operations Officer Sanjeev Singh and several senior vice presidents as Wipro wades through a years-long turnaround of its business. "The loss of key leaders continuing into the fourth year of turnaround will not be viewed favorably by investors," analysts at Kotak Institutional Equities wrote in a note.
