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. Shares of this oil and gas exploration and production company have returned -2.9% over the past month versus the Zacks S&P 500 composite's +2.1% change. The Zacks Oil and Gas - Integrated - United States industry, to which Occidental belongs, has lost 2.2% over this period. Now the key question is: Where could the stock be headed in the near term? While media releases or rumors about a substantial change in a company's business prospects usually make its stock 'trending' and lead to an immediate price change, there are always some fundamental facts that eventually dominate the buy-and-hold decision-making. Revisions to Earnings Estimates Rather than focusing on anything else, we at Zacks prioritize evaluating the change in a company's earnings projection. This is because we believe the fair value for its stock is determined by the present value of its future stream of earnings. Our analysis is essentially based on how sell-side analysts covering the stock are revising their earnings estimates to take the latest business trends into account. When earnings estimates for a company go up, the fair value for its stock goes up as well. And when a stock's fair value is higher than its current market price, investors tend to buy the stock, resulting in its price moving upward. Because of this, empirical studies indicate a strong correlation between trends in earnings estimate revisions and short-term stock price movements. For the current quarter, Occidental is expected to post earnings of $1.17 per share, indicating a change of -63% from the year-ago quarter. The Zacks Consensus Estimate has changed -13.1% over the last 30 days. For the current fiscal year, the consensus earnings estimate of $5.19 points to a change of -44.5% from the prior year. Over the last 30 days, this estimate has changed -10.6%. For the next fiscal year, the consensus earnings estimate of $6.31 indicates a change of +21.5% from what Occidental is expected to report a year ago. Over the past month, the estimate has changed -4.3%. 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).

Valuation No investment decision can be efficient without considering a stock's valuation. Whether a stock's current price rightly reflects the intrinsic value of the underlying business and the company's growth prospects is an essential determinant of its future price performance. While comparing the current values of a company's valuation multiples, such as price-to-earnings (P/E), price-to-sales (P/S) and price-to-cash flow (P/CF), with its own historical values helps determine whether its stock is fairly valued, overvalued, or undervalued, comparing the company relative to its peers on these parameters gives a good sense of the reasonability of the stock's price. 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. Click here to see the values of some of the valuation metrics that have driven this grade. Conclusion The facts discussed here and much other information on Zacks.com might help determine whether or not it's worthwhile paying attention to the market buzz about Occidental. However, its Zacks Rank #3 does suggest that it may perform in line with the broader market in the near term.
