Chevron Corp.'s (CVX) stock is already 16% off its 2018 highs, and now falling oil prices may push shares even lower. Technical analysis suggests that Chevron's stock may drop an additional 7%.

Oil prices have dropped by 13% since hitting an intraday high of roughly $77 per barrel on October 3. But now those prices may be heading lower as the U.S. dollar strengthens. 

Breaking Down

Chevron's stock is trading around a critical level of technical support at $111.80. Should the stock fall below that support level it may result in the stock drifting even lower to its next level of support at $103.50 from its current price of $111.50.

The relative strength index (RSI) for Chevron has been steadily falling since peaking at overbought levels in early 2018. Additionally, volume levels have been steadily rising as the stock price has dropped, suggesting an increasing number of sellers. 

Falling Oil

Oil prices have been steadily falling in recent weeks and may fall even further. Oil is currently sitting above technical support around $65. Should the price fall below $65 it could drop to as low as $61. The RSI for oil has been trending lower which suggests bullish momentum is coming out of oil.  

Strong Dollar

One reason why oil may be due to drop is that the dollar index, which is an index to measure the value of the dollar versus a basket of foreign currencies, is technically breaking out. A rising dollar puts downward pressure on commodity prices because it takes fewer dollars to buy the same number of units of the commodity. Should the dollar index rise above resistance around 96.75, it may increase to 98. 

Should oil fall, it would have a negative impact on Chevron's stock because investors would begin to grow more cautious on the company's future revenue and earnings potential. But despite all the weakness in the oil markets, analysts have yet to lower their estimates for the company. In fact, since the end of September, forecasts for the balance of 2018 have increased. Should oil prices fall further, it could result in analysts having to cut estimates, potentially taking Chevron's stock lower with it.
