Hedge roll-over

I just rolled-over the SPY put option hedge from the Sep 144 to the Dec 144 contract. The September contracts were purchased for $1.55 on June 1 and sold for $2.80. The Dec 144 contracts were bought for $4.80.

Hello Science trader,

A question regarding your performance chart - is this the overall performance after any offset by the hedge?

If this is after the hedge, there's been a substatial drawdown, hasn't there? Do you consider the SPX to be a good hedge? I trade a portfolio of systems and use the SPX, NDX and Russel 2000 - after realising the SPX was a poor overall hedge for me.

Keep up the fantastic blog and work.

Regards,
Richard

Hi Richard,
Thanks for your kind words. Yes, it is overall performance including the options positions. I agree that the drawdown is substantial. Part of the reason is that I made a major change in the portfolio (got rid of extreme-os), which can mean in theory that you hit a drawdown in the earlier portfolio, and then again in the new portfolio. So, normally I don't like to make these major changes, but because of technical problems with autotrading I had to change things quite suddenly, instead of more gradual. At the same time, all systems currently in the portfolio are in drawdown, and some are close to or exceeding their historical max drawdown (e.g. Longstoch-ST and Weekend Trader).
I have been thinking about setting up a multi-index hedge, but the fit of the model doesn't get a lot better when going from one index to two or three in my case. Even though, it is safer in theory to hedge against multiple indices and perhaps I will replace some of the SPY options by QQQQ options (which trade in pennies, so that would be an additional advantage).
Do you trade a portfolio of your own systems, or third-party systems?

One more thing: I use twice the leverage as the systems do on C2. So, it is expected that in case of a sell-off in the general market, drawdowns without the hedge will be unacceptably high. I.e. I would never use 2x leverage without a hedge in place. The worst case scenario would be (apart from the systems simply stopping to work) when all 4 systems would suffer a major drawdown at the same time, while no simultaneous sell-off would occur in the broader market. I see that as highly unlikely, and the more systems I add to the portfolio the smaller that probability will become.

ST,

aha, I'd missed the 2X margin factor. That explains somewhat.

I trade my own systems, and 3rd party systems. My long portfolio comprises about 20(the beauty of mechanical) systems, about 15 of which (60% of portfolio) are derived from Stock investor pro fundamental screens. I have a few of my own (more price momentum based) and subscribe to Trend Plays at C2.

On the short side I'm 110% hedged * against a mix of FTSE100, SPX, NDX and Russsel 2000 indeces.

*This hedge is then reduced proportionaly (to 70% min) based on long signals from numerous 3rd parts signal providers. These are;

CTS Snapback (at C2)
Druster
EOD trading signals (under trial)

It's working well over the last few years but I suspect as much by luck as judgement.

I will work full time at this from Christmas and intend to get deeper into systems development.

Cheers,
Rich

Wow, that's a lot of systems--quite diversified. To further clarify my hedging philosophy: I assume that to some extent long-only systems don't have to be hedged, e.g. for the last years all systems I trade dealt reasonably well with the periods the S&P500 was in drawdown. If the market would continue to behave the way it did during the past year, I'd prefer not to be hedged. But because that's an unlikely scenario, I want to hedge against more extreme scenarios, e.g. a crash like 1987 or a more gradual 50% decline like in 2001-2003. For that reason I have the strikes of my put options about equal to the largest drawdown the index has seen over the past year. In other words, the hedge (in a beta or delta sense) is far smaller when the index is in no or minor drawdown, and gets to 100% once the index approaches its max drawdown for the period I can observe the performance of the systems I trade.

Hi there!
I would like to burn a theme at here. There is such a thing, called HYIP, or High Yield Investment Program. It reminds of ponzy-like structure, but in rare cases one may happen to meet a company that really pays up to 2% daily not on invested money, but from real profits.

For several years , I make money with the help of these programs.
I'm with no money problems now, but there are heights that must be conquered . I get now up to 2G a day , and I started with funny 500 bucks.
Right now, I managed to catch a guaranteed variant to make a sharp rise . Visit my blog to get additional info.
