Mortgage Redrawn

Just enter the amount, press the button, and:

Now to transfer the money to investment. This is how I account for this re-structure:

Almost all our historical savings from wages etc ("current savings") have now been converted into housing equity and extra retirement contributions. Housing equity is now a few hundred dollars short of the value of the house as I left a small amount of the mortgage unpaid in order not to potentially trigger something undesirable by totally paying it off.

Mortgage Almost Paid Off

It won't be for long!

Trading and Mortgage Inversion Update

We switched from short one contract of Bitcoin to long two this morning, booking a USD 30 loss on the short trade. We are long two as the per contract risk is lower now. After four losing Bitcoin trades, hopefully this is a winning one...

I sold a lot of shares this morning and already was allowed to move some of the proceeds to our offset account. I also paid down AUD 100k of the mortgage and was surprised to see that I could redraw it immediately. I had thought I would need to wait to 4th November for the redraw balance to update. This means that I might be able to complete the inversion this week.

P.S.

So I paid off another AUD 300k later in the day. Am still waiting on a transfer of AUD 100k from my margin loan. When I get it I should be able to complete the "inversion".

Optimizing Trading Portfolios and Shifting to Return on Risk Metric

I started exploring testing portfolios of trading strategies. For this, I decided that in looking at return on capital where capital is the face value of a futures contract doesn't make much sense. It seems to make more sense to look at the return on money at risk. It makes the most sense to measure that in dollars as a share of a total risk budget. This then leads me to making the primary measure of return also to be in dollars. Here is an optimized portfolio of Bitcoin, oil, and palladium:

The portfolio has a total risk budget of USD 5,000. This is then allocated across the three markets with the resulting profit curves. The analysis assumes that you can trade fractional futures contracts. Oil and palladium help diversify Bitcoin and increase the information ratio. Using a zero benchmark and daily returns on risk the portfolio IR is 2.96 rising from 2.17 for Bitcoin alone.

Oil hasn't gone anywhere in the last year, but did well in 2018 when Bitcoin struggled. Going forward, I will test whether each new market I look at improves the portfolio IR or not.

This approach then also leads to computing the prices for continuous futures contracts additively rather than multiplicatively – so that differences in dollars are preserved -– and to focusing on a constant risk budget in dollars. It also allowed me to simplify the back-testing program quite a bit. In the following chart the blue line is the daily profit curve for trading one contract of Bitcoin futures:

The red curve is based on completed trades only. The green curve has a constant dollar risk equal to the average of the single contract. To be more realistic I have rounded the number of contracts to the nearest whole number, which could be zero. This keeps the strategy out of the market in late 2017 and early 2018, when the single contract strategy had a big drawdown. The constant risk strategy has a higher return and a smaller maximum drawdown than trading a single contract. So, this is the strategy I am adopting for Bitcoin going forward. This morning, we switched from one contract long to one contract short...
