Amazon.com Inc.'s (AMZN) shares have plummeted more than 20% from their all-time high in September, which amounts to a $200 billion decline in market capitalization. But battered investors may get a bit of a respite. Now, chart analysis suggests the stock is nearing a technical reversal, which could send the stock 10% higher in the short term - over the next few weeks.

Nearing A Break Out

The chart shows the shares trading around a technical resistance level at $1,620. Should the stock trade above that point, the shares are likely to rise to $1,760 from its closing price of $1,598 on Wednesday. That would be a 10% gain. Should the stock fail to rise above resistance at $1620, it could decline as much as 8%.

Additionally, the relative strength index also suggests the shares may rise after hitting oversold levels. 

Cutting Estimates

To be sure, a short-term rebound doesn't mean Amazon will advance longterm. The shares are likely to continue to face longer-term challenges after delivering weak quarterly results, with revenue coming in below estimates. It was the second quarter in a row that the company missed revenue estimates. Even worse, analysts have reduced their revenue estimates by 3% for the fourth quarter. 

Falling Full-Year Estimates 

Perhaps more problematic is that revenue estimates have been shaved for 2018 and the next two years.

A major obstacle facing Amazon and its investors is the stock's valuation. Even with the recent steep declines, Amazon is still trading at well above its historical one-year forward price to sales ratio at 2.78. This rich valuation and the company's slower growth outlook suggest the stock faces stiff headwinds ahead.
