$NVIDIA(NVDA.US) For short-term trading, look at the annual moving average, which is around 191. As long as it doesn't clearly break below, the closer it gets, the more you buy. The annual moving average is the defensive line; if it officially breaks, then cut losses. To put it bluntly, it's all a gamble, betting that it's highly unlikely to actually break below the annual moving average.

Long-term investment looks at basic factors. There are more capable people here to explain basic factors. Before the big tech earnings reports, what I'm curious about is whether, after experiencing the recent series of storage events, they will mention any news about slowing capital expenditures in their conference calls. As long as one company has this idea, how big of an impact would it have on NVIDIA? In the long run, under the influence of the base effect, a slowdown in spending growth is almost inevitable. But as for what they'll say in the earnings call two weeks from now, or the short-term stock price movement, that's unpredictable.
