Arrows Up And Down

A knock for Nook? Barnes & Noble’s share price fell 10 percent as Jeff Bezos announced not just a Kindle tablet but a revision to Amazon’s core e-ink e-reader range, and it closed down nearly seven percent on the day.

RIM (NSDQ: RIMM), whose Playbook maker also manufactures Amazon’s Fire, fell by less than one percentage on the news out of New York but finished the day down three percent on a day when the tech-focused Nasdaq was down a little over two percent.

But Apple (NSDQ: AAPL) investors are unmoved, or perhaps even bullish. Stock in the iPad maker immediately rose on opening and stayed steady through Bezos’ announcement but wound up falling just 0.56 percent.

Amazon (NSDQ: AMZN) was trading three percent up after the unveiling, and finished up 2.45 percent.
