on Friday last week Nvidia announce earnings for 4Q , net income and ravenue fall about 50% but shares price are up, someone said that I don't understand NVIDIA's business mode???? someone knows why income of NVIDA fall but shares are up?
There was uncertainty about their revenue/profit so NVDA tanked in the weeks/months leading up to earnings. Once the uncertainty was removed, the stock was happy.
If you trade on fundamentals, you will highly likely to see your account wiped out. Some people call it manuipulation while others say that stock markets follow a random walk. However, both are wrong. In fact, It is actually called liquidity Premium. Check other stocks in the same index, they probably had the same bullish move
I think it was not the case I am afraid. You may have got the idea from some news articles as they tend to make up stories. However, most stocks, commodities and forex showed the strength on Friday if you check the chart. It was driven for liquidity premium. If there was uncertainty, then price should have risen before the earnings, and not after.
