I’m putting together a framework to evolve, test, and optimize signals using a genetic algorithm approach. Signals with statistically significant results will be further combined into bayseian networks and fed back into this testing framework.
Determining the conditionality of one signal against another requires insight and guesswork, or evaluating permutations of networks. With a GA optimizer and enough computing power should be able to determine networks that successfully amplify the combination of signals to one that is correct more often than not (or at least is more successful in the profitable situations than the losing ones).
The universe of events and indicators that have potential to be significant is large, as are their parameterizations. Choosing the search space will be a challenge, as is sometimes having access to the required data.
I plan to overlay our tick UI with trading signal indicators indicating a probability weighting when a signal reaches a non-neutral threshold. Should be interesting to visualize the results.
I noticed that BIDU, one of the stronger stocks in the chinese market has outperformed FXI consistently both with upside and downside market moves. In other words, when the market is in a strong downward trend (as it is now), BIDU has gone down less than FXI. When the market was appreciating BIDU outperformed FXI.
Assuming this relationship holds on the near term, speculative play: long BIDU, short FXI. Should yield return in an upward or downward trending market.
The china vs taiwan spread trade has done well in the short term with 7% gains over the last two days, but not for the reasons I discussed in the previous post. I noticed that the markets are cointegrated, however moves in the china market (both positive and negative) have a steeper slope, so that positive and negative moves are bigger with FXI than for EWT.
Given the current downward trend for FXI, the FXI – EWT spread contracted, yielding 7%. Of course should the trend reverse and FXI recover, would expect the spread to flip back to a widening phase.
I think a better trade at this point is a view towards continued growth in the indian market accompanied with a deflation of the chinese market bubble. Speculative trade: short FXI, long INP.
If one looks at the annual performance of FXI (China index) versus EWH (HK index), we see a widening spread over the last year, but a lot of simularity in the chart patterns. I suspect these markets are cointegrated, but with a scaling factor (a difference in slope).
This article indicates that chinese will soon be able to invest in the HK market. With the huge flow of speculative money in China soon to be able to find alternative venues (such as HK), should expect to see a move of some of this buying pressure into the HK market.
A speculative play: looking to see a contracting FXI – EWH spread. Trade: buy EHW, sell FXI.
I was looking at investments offered in my offshore account and came across the following structure:
- 5 year investment into china fund
- capital preservation (built-in floor at initial investment level)
- max 55% return total across 5 years, the bank pockets the excess above
For someone not in the financial business this may seem to be a good deal (seeing the 55% and capital preservation). I think it is a relatively poor deal though. The continuously compounded effective annual rate is only ~8% and that is only achieved if the market does indeed appreciate 55%.
I began thinking about how closely could replicate this structure on my own, but with a much higher max payoff. Though the payoff function I am going to indicate is not perfect (I can go under my initial capital if the timing of my protection is not right), would do as follows:
- buy into FXI index
- allow some appreciation and then buy the 1 month put option at the initial point of entry
On an ongoing basis:
- roll put option at initial investment point + cost of option premiums thus far, maybe with longer maturity
- if FXI drops below initial investment, sell FXI, sell option, coverage should be close to offsetting
- as and if FXI approaches entry point buy in again and buy protection
Of course one can structure this more advantageously:
- additional protection (by adjusting strike upwards as FXI gains)
- reentering trade if FXI falls at lower level rather than initial investment level
The cost of the options is paid for out of the returns or in the worst case through the adjusted strike price. That said, increasingly, the options are going to be deeper and deeper out of the money if FXI continues to be a good investment (meaning cheaper hedging costs).
