HOUSTON, Oct 21 (Reuters) - Exxon Mobil Corp (XOM.N) shares passed their all-time high on Friday as oil prices resumed their climb and analysts raised their long-term views of top U.S. oil producer's cash flow and earnings outlook. The stock hit $106.40 on Friday before closing at $105.86, above the prior record high close of $104.59 from June 8. The strategy paid this year as an international oil supply crunch accelerated by sanctions against Russia made oil prices hit 14-highs. For a time, utility operator NextEra Energy overtook Exxon as the U.S. energy company with the largest market cap. The year's profits are largely from high energy prices.
