Here is my opinion. When a stock does not move down, then someone is buying and someone else is selling. Haha. Simple enough.
The question of the day is why hasnt the stock suddenly dumped down and just who is selling, just who is buying? Both parties have their reasons but there is some equilbrium in the price. Each time shares are sold someone is catching them.
So this is where a straddle comes in handy when we are certain the price will swing in a violent direction that could be up or down.
Now you have to bet who has the better information, the person who is buying or the person who is selling...I say it goes higher, but these trades are very risky so straddling is the best move here.
