The SP500 rocket is about ready for takeoff. My P/L is going to be stellar this morning. I will likely need to roll some of my positions since i've gotten most of the premium out of them.
I agree, single leg slides are boring, but a bit of ramp up first would be nice.I asked him if price will go up or down when it reaches the bottom, he said down, so this is clearly a bearish pattern.
What kind of lookback period are you using for determining the levels of correlation? Is this lookback period related to the holding period of your positions?A standard correlation check does not look at magnitude it just looks at direction. So using that correlation table I can quickly see my position-to-position and portfolio correlations. I obviously want a low correlation to help reduce risk and volatility of my portfolio.
I like to look at 30 day correlations. It's long enough to filter out some of the noise, but short enough to not be too laggy if there are sudden shifts in correlation. Most of my positions come off the board after 1-4 weeks depending on how quickly volatility contracts and if my strikes get tested. If i'm forced to defend a position it might be on the board for a number of months.What kind of lookback period are you using for determining the levels of correlation?

Correlations are funny things. Its always amazing seeing what markets decide to correlate or uncorrelate. And they are always different between each volatility spike. These are still just back of the envelope checks and generally speaking, the increase in correlation during hightened volatility is not material enough to cause me to adjust positions. Only during very extreme and prolonged volatility does that become the case.Interesting. 30 trading days is about 6 calendar weeks. Only a bit longer than the usual holding period of your positions (1~4 weeks). My guess is, but I have no proof for it, that the recent increase in volatility on the markets also creates larger changes in correlations between instruments. Which might seem as more "noise" in the correlations you see. Anyway, if this combination of parameter settings work well for you yo should stick to it.
