AAPl AAPL AAPL

For all those apple die hard fans, AAPL is trading near its 200-DMA. This has happened only once in the last 1 year. It tested its 200DMA only once in Dec-2012. It wasn't successful as there was not enough volume.

Now, the optimist scenario. If AAPL succeeds in crossing the 200DMA($473) right now, with good volume(more than 1.5x average volume), this could push apple towards $500.

This will be a significant event for the stock. All the traders and big money managers watch this DMA. Close above this 200DMA would bring in those buyers and would take apple higher in relatively short amount of time.

Oracle Optimizer costing algorithm

This is my presentation on how Oracle Optimizer comes up a cost of accessing any table or any index.
I have also shown how the cost of any join in computed. I hope this will provide enough information for you to understand the concept and apply it to your problems.
