Quote from tradingjournals:
The SPY/12EWJ spread went down from above 1.3 yesterday to 1.25 today.
TJ, let me help you out here. When a spread blows out and makes 15% in 2 days, you sell it. There is no reason to be in that spread now. When I said that spread was a good trade, it was before the Nikkei crashed. I of course had no idea the Nikkei would crash. My thought at the time was that the situation was bad over there but not dire. I felt going forward that spread would be a good way to express a point of view on volatility that Japan would be more volatile then our markets and that over time that spread would widen.
What ended up happening is the Nikkei crashed. It dropped 20% in 2 days. I would have thought that it would have taken months for that to happen but it happened in 2 days. When a spread blows out like that, you sell it.
Another way to look at it is this, if you did not have the spread on, would you put it on now? And the answer is no, I would not. In fact, now that Japan has crashed I would probably reverse the spread although I think it's still pretty risky getting long Japan now.
You see TJ, the reason guys spread is to express a point of view that isolates exactly what they want to express and to exclude everything else. That spread will continue to come in because Japan is more volatile then our markets.
If you would start looking at relationships in the market you would be a better trader instead of asking people if they are bullish or bearish. Everything in the market is relative.
