NEW YORK (TheStreet) -- FedEx(FDX) - Get Report shares will likely face a bumpy ride when the company reports earnings Wednesday. Here's the data and how to trade the stock.

Volatility in FedEx shares isn't unprecedented. Shares of FedEx had been tracking their 200-day simple moving average higher since January 2012. After shares set an all-time high on June 11, the company missed earnings estimates on June 17 and by July 1 the stock was below its 200-day simple moving average. The stock is thus set up for another volatile ride in reaction to earnings.

Analysts expect FedEx to earn $2.44 a share when the company reports results before the opening bell on Wednesday. As a global package delivery company, FedEx has currency convergence risk. In the U.S. communities where Amazon(AMZN) - Get Report has fulfillment centers, FedEx has lost market share as local deliveries are done by the U.S. Postal Service even on Sundays and holidays.

The daily chart shows that FedEx held its 200-day simple moving average on weakness on March 27 and April 1 as this average was rising at $163.44 to $163.94. The company beat earnings estimates on March 18, so weakness to this moving average support provided a buying opportunity.

Going into the company's last earnings report released on June 17, the stock was on an upswing that achieved the all-time intraday high of $185.19 on June 11. The earnings miss released before the opening bell on June 17 caused a price gap lower at the open. From June 29 through July 1, the stock tried to hold its 200-day simple moving average, then at $171.30.

The close below the 200-day that day made the 200-day simple moving average a technical resistance, last tested at $172.88 on Aug. 5.

On Aug. 11 came a dreaded "death cross," where the 50-day simple moving average in blue crossed below the 200-day simple moving average in green, indicating that additional downside was the likely path ahead. This put shares at risk going into the price action that climaxed on "Black Monday," Aug. 24.

Shares of FedEx were already sliding with a close of $156.03 on Aug. 21. The open on Aug. 24 was a downside price gap of 6.1%, with the stock suffering a 10 minute flash crash of 16.7% from the Aug. 21 close to a flash crash low of $130.13. From the all-time high to this low the stock was in bear market territory, down 29.8%.

From Monday's close of $150.23, the stock is down 13.5% year to date and is in correction territory, down 18.9% from the all-time high.
