Occidental Petroleum (OXY) is one of the stocks most watched by Zacks.com visitors lately. So, it might be a good idea to review some of the factors that might affect the near-term performance of the stock.Over the past month, shares of this oil and gas exploration and production company have returned -18.8%, compared to the Zacks S&P 500 composite's -0.6% change. During this period, the Zacks Oil and Gas - Integrated - United States industry, which Occidental falls in, has lost 15.4%. The key question now is: What could be the stock's future direction?Although media reports or rumors about a significant change in a company's business prospects usually cause its stock to trend and lead to an immediate price change, there are always certain fundamental factors that ultimately drive the buy-and-hold decision.Earnings Estimate RevisionsHere at Zacks, we prioritize appraising the change in the projection of a company's future earnings over anything else. That's because we believe the present value of its future stream of earnings is what determines the fair value for its stock.We essentially look at how sell-side analysts covering the stock are revising their earnings estimates to reflect the impact of the latest business trends. And if earnings estimates go up for a company, the fair value for its stock goes up. A higher fair value than the current market price drives investors' interest in buying the stock, leading to its price moving higher. This is why empirical research shows a strong correlation between trends in earnings estimate revisions and near-term stock price movements.For the current quarter, Occidental is expected to post earnings of $2.88 per share, indicating a change of +800% from the year-ago quarter. The Zacks Consensus Estimate has changed +3.3% over the last 30 days.For the current fiscal year, the consensus earnings estimate of $10.36 points to a change of +306.3% from the prior year. Over the last 30 days, this estimate has changed +4.4%.For the next fiscal year, the consensus earnings estimate of $8.45 indicates a change of -18.4% from what Occidental is expected to report a year ago. Over the past month, the estimate has changed +5%.Having a strong externally audited track record, our proprietary stock rating tool, the Zacks Rank, offers a more conclusive picture of a stock's price direction in the near term, since it effectively harnesses the power of earnings estimate revisions. Due to the size of the recent change in the consensus estimate, along with three other factors related to earnings estimates, Occidental is rated Zacks Rank #3 (Hold).The chart below shows the evolution of the company's forward 12-month consensus EPS estimate:12 Month EPSProjected Revenue GrowthWhile earnings growth is arguably the most superior indicator of a company's financial health, nothing happens as such if a business isn't able to grow its revenues. After all, it's nearly impossible for a company to increase its earnings for an extended period without increasing its revenues. So, it's important to know a company's potential revenue growth.In the case of Occidental, the consensus sales estimate of $9.64 billion for the current quarter points to a year-over-year change of +60.3%. The $38 billion and $36.28 billion estimates for the current and next fiscal years indicate changes of +44.4% and -4.5%, respectively.Last Reported Results and Surprise HistoryOccidental reported revenues of $8.53 billion in the last reported quarter, representing a year-over-year change of +55.7%. EPS of $2.12 for the same period compares with -$0.15 a year ago.Compared to the Zacks Consensus Estimate of $7.96 billion, the reported revenues represent a surprise of +7.2%. The EPS surprise was +7.61%.Over the last four quarters, Occidental surpassed consensus EPS estimates three times. The company topped consensus revenue estimates each time over this period.ValuationWithout considering a stock's valuation, no investment decision can be efficient. In predicting a stock's future price performance, it's crucial to determine whether its current price correctly reflects the intrinsic value of the underlying business and the company's growth prospects.Comparing the current value of a company's valuation multiples, such as its price-to-earnings (P/E), price-to-sales (P/S), and price-to-cash flow (P/CF), to its own historical values helps ascertain whether its stock is fairly valued, overvalued, or undervalued, whereas comparing the company relative to its peers on these parameters gives a good sense of how reasonable its stock price is.As part of the Zacks Style Scores system, the Zacks Value Style Score (which evaluates both traditional and unconventional valuation metrics) organizes stocks into five groups ranging from A to F (A is better than B; B is better than C; and so on), making it helpful in identifying whether a stock is overvalued, rightly valued, or temporarily undervalued.Occidental is graded A on this front, indicating that it is trading at a discount to its peers.
