HEXUS.sharewatch: NVIDIA leads tech rollercoaster back down again

One advantage of being an NVIDIA investor is that there's never a dull moment. It must be the most volatile stock on our list and this past week was no exception.

NVIDIA announced a 60 percent drop in quarterly revenues last week, which was even more than it had warned previously. This precipitated a fall of nearly 13 percent in the value of its shares in the following day's trading and they've stayed at more or less that level.

The rest of our list showed modest falls roughly in keeping with the declines in the broader indices, with the sole exception being AMD.

Despite seeing its shares suffer a downward plunge when it announced the postponement of the shareholder meeting to approve the formation of The Foundry Company, due to insufficient votes having been cast, AMD managed to be the only stock not to decline last week.

One of the reasons for this could be some signs of optimism from analysts on the fortunes of the semiconductor industry, but if so why hasn't Intel benefitted? Perhaps investors aren't convinced by Intel's recently announced spending plans.
