Trefis members have created forecasts for two drivers of Amazon's ( AMZN) stock over the last week: (1) Kindle Pricing, (2) Kindle Units Sold. Their forecasts suggest that Kindle Pricing will not decline as low as the Trefis forecast, while Kindle Units Sold will not rise as high as the Trefis forecast.These projections suggest a net upside of less than 1% for Amazon's stock. Amazon's Kindle e-reader device competes with e-readers and tablets from players like Apple ( AAPL), Sony ( SNE) and HP ( HPQ). Amazon's Kindle Hardware constitutes only 1.3% of the $119 Trefis price estimate for Amazon's stock. In comparison, Electronics & General Merchandise is 48%; Books, DVDs and Music is 37%; and Cloud and Other Web Services is close to 4% of the Trefis estimate for Amazon's stock. Since Kindle forms a very small part of Amazon's overall business, Amazon's stock is not impacted much by 1) Kindle Pricing and 2) Kindle Units Sold. Below are the charts showing recent estimates created by Trefis members for the two drivers.
