Reviving Old Trading Models

I dug into my computer files and updated the trading models I last used 10 years ago. One of them which is fairly simple flashed a strong warning sign at the January high in the market. It does tend to have false positives where it is fooled by a very strong trend into thinking that that is a top in the market, but this time the market actually did fall of course after the warning. This is a very negative signal. There was a minor buy signal at the recent low about a week back but there are typical several buy signals on the way down in bear markets. I had been looking for signs of a recession before taking de-risking action in a big way on our portfolio - for example, an inversion of the yield curve. There hasn't been any sign of a recession. But Trump's trade war and the Fed's unwinding of its inflated balance sheet are having a negative effect on the market.

I have another much more complex model that attempts to forecast the day ahead direction of the market - despite what standard investment theory says, that the stock market is a random walk and can't be predicted this is actually possible to some degree with some insight from econometrics into how to turn it into a predictable problem. I updated the model using the last ten years of data and reoptimized the parameters - they hardly changed. That is a good sign. However, though I have all the past predictions and the trade directions I decided on based on them, I can't remember how I used the model to actually choose market direction. Unless I can find something I wrote about that, I'll have to reverse engineer that from scratch.

P.S.
I found a folder of handwritten research notes on my trading model from 2006-8 in my home office. This should help a lot.

P.P.S.
I predict the US will go into recession in 2019. In 2007 the stock market peaked in Summer-Fall but the recession didn't really get started till Bear-Stearns failed in March 2008. In 1999-2000 the stockmarket peaked in March 2000 but the recession didn't really get going till September 11, 2001.

Types of Trading

There are lots of types of trading. Some of the important strategies are the following:

1. Market-making: A market maker profits from the bid-ask spread in the market, selling at the ask and buying at the bid. This is very apparent in options markets where there is usually a big bid-ask spread. They can hedge their "delta" risk by buying or shorting the underlying security - for example for futures options they can buy and sell futures contracts. For individual stocks - if they are trading a diversified basket they can again hedge using futures contracts (or ETFs). It is possible for individual investors to make markets in small and illiquid stocks - ie. selling at the ask and buying at the bid, but it is a very slow process waiting for people to trade with you.

2. Arbitrage: This exploits pricing anomalies, for example between futures contracts and ETFs for the same underlying index. Short one and buy the other. Occasionally, there are big arbitrage opportunities such as the famous Palm case.

3. Mean reversion: These are generalizations of arbitrage. For example, buying closed end funds (listed investment company in Australian) when they are selling below net asset value and shorting them when they are above. I've done this quite a lot with Platinum Capital (PMC.AX - just selling when above NAV - but actually there is a CFD you could use to short the stock). This is arbitrage between the value of the portfolio and the price of the fund. Statistical arbitrage is a market-neutral mean reversion trade where stocks that have risen in value are shorted and those that have fallen are bought. It was pioneered by Ed Thorp.

4. Selling option premium: This relies on the time decay of options. Most options expire worthless and risk aversion means that buyers should pay in net to reduce their risk. So option sellers should on average win. Again, delta risk could be hedged away in theory. The simplest case is covered calls where the trader buys a stock and sell a call - though actual delta hedging is a lot more complex than that.

5. Information trading: Here the trader knows information that they think will move the security. For example, recently I bought shares in IPE because Mercantile did. I assumed correctly that their analysis must have shown that the underlying portfolio was worth more than the stock price. This is a kind of mean reversion/arbitrage of course and is could also be seen as investing. Even after the company released news of the sale of Threatmetrix to Elsevier, the price didn't immediately move to the new higher NAV.

6. News trading: Here the information is not yet known but a trade is placed to take advantage of it. For example, if I know that Apple Computer will release their earnings but I don't have a hypothesis of which way it will move the stock, I could buy both calls and put options in the hope that a big move will make one increase by more than the other decreases. This seems pretty close to gambling - option prices should take into account the size of likely moves, so you are gambling that the move will be bigger than the market thinks.

7. Trend following/momentum trading: This is what most people think of as trading. The trader tries to take advantage of market momentum. This is the approach taken by many managed futures funds. Much online trading advice is based on this.

8. Hedging: These traders trade to hedge their investment or business positions. For example, an airline buying oil futures contracts to guarantee their future price of oil or an option buyer hedging an investment portfolio. The latter might also sell options to fund the hedging puts.

What have I missed? This paper has an interesting discussion of types of traders.

First Futures Trades Since 2008

I transferred some money from my Australian bank account to Interactive Brokers to do some practice trades. I haven't traded futures since 2008 and so just want to get used to doing trades again. I did 2 very quick daytrades, shorting the E-Mini S&P. The first trade I got out where I got in and so I lost $4.10 the cost of commissions. On the next trade I made 1 point or $50, so I made $46.90 net. I was very nervous while doing the trades even though I am trading with a stop that is transmitted at the same time as my order and is only one point above my sell price, so the most I can lose is $50.  The contract value is $130k (about my pretax annual salary :)), so short selling that much stock does make me feel nervous despite the stop. I've just got to get used to this again as I am thinking of doing more systematic trading again and doing it properly this time. When I traded before, I had lots of winning trades but my winning amounts were small relative to my losing amounts. If I can fix that I could trade profitably.

March 2018 Report

The first of the new style reports. A second losing month, but thanks to (listed) private equity investments, we beat the ASX200 index.

The Australian Dollar fell from USD 0.7794 to USD 0.7680. The MSCI World Index fell 2.15%, and the S&P 500 2.54%. The ASX 200 lost 3.77%. All these are total returns including dividends. We lost 1.20% in Australian Dollar terms and 2.64% in US Dollar terms. So, we outperformed the Australian market and underperformed international markets.

The best performing investment in dollar terms was IPE.AX, a listed private equity fund, which gained AUD 9.8k in the continuing rise after the acquisition of Threatmetrix by Elsevier. I sold my holding in IPE prior to the stock going ex dividend, as I didn't want an AUD 11k income tax bill. I then bought back even more shares than before as MVT.AX were recently still acquiring shares.

The worst performer in dollar terms was not surprisingly CFS Geared Share Fund, down $18.6k. The best performing asset class was private equity, which gained 7.12%. The only other asset class with gains was hedge funds, up 0.57%. The worst performing asset class was large cap Australian stocks down 3.01%.

We made a little progress towards the new long-run asset allocation:

Total leverage includes borrowing inside leveraged (geared) mutual (managed) funds. The allocation is according to total assets including the true exposure in leveraged mutual funds. The "improvement" in allocation, came partly due to market movements and partly due to investment activity. We invest AUD 2000 monthly in a set of managed funds, and there are also retirement contributions. Then there are distributions from funds and dividends. During the month, I also:

• Sold out of Clime Capital (CAM.AX)
• Bought a small amount of Oceania Capital Partners (OCP.AX, listed private equity)
• Did the trading in IPE.AX
• Bought more units in the Winton Global Alpha fund (managed futures - in the commodities category)

Over time we've been reducing our exposure to large cap Australian stocks since the post financial crisis high:

New Era in Moomin Valley

In a few months we will reach "financial independence" - our annual spending will be feasible with a little less than a 3% p.a. withdrawal rate. About 60% of this was due to our own efforts working, saving, and investing over the last 24 years and 40% from inheritance. I never depended on receiving the inheritance, which is why I saved so hard. Because I knew finding an academic job could be very hard when my initial short-term contracts ended, I saved up to 50% a year at times. This allowed me to live for a year in 2001-2 without working for pay, traveling around the world looking for work. Similarly, when we moved to Australia, I could experiment with trading in the financial markets while exploring alternatives.

On the other hand, I think I was willing to take more risk based on the probability that we would receive a substantial amount. In the case of the financial crisis in 2008-9, I took on too much risk. The pressure of trying to make a living from trading with a small amount of capital combined with the volatility of the financial crisis was too much and I decided to stage an academic career comeback, which has been very successful.

The other half of the financial independence equation in the blogging community is usually "retire early". I don't have any plan to do that any time soon. I like the research side of my work and I have my teaching etc organized so that going forward it shouldn't be too hard - I only need to teach during one half of the year for now. As things are at the moment, it would be hard to find a better job than this. So, it doesn't make any sense to sacrifice my salary. I am actually exploring a potential career move to another bigger city. That job would have more admin and maybe no teaching. Introspection tells me that I wouldn't like to retire currently.  On the other hand, Moominmama is pretty frustrated with her work at the moment and so now has options to take a break and consider alternatives.

On the other hand, our spending is growing by more than the rate of inflation and I expect that to continue. So the current 3% withdrawal rate would become more than a 3% rate over time unless investment returns are very good, which does not seem likely. Continuing to earn some money does sound good in those circumstances.

Is continuing to work limiting our location choices? At the moment, I don't think there is another location that we would both agree on and which would make practical sense. We have to consider education opportunities for little Moomin. So, moving to a small town in Australia does not sound like a good move from that perspective. The nice parts (with good education) of the two biggest Australian cities are extremely expensive and would take us out of the financial independence zone. We definitely would never move to Moominmama's home country (she doesn't even want to visit at the moment). Moominmama is not enthusiastic about moving to either of my home countries. One is too cold and dark as far as she is concerned (Northern Europe) and the other too foreign and dangerous (Middle East). That leaves Southern Europe as a sensible or feasible alternative, but I don't think we want Moomin to grow up speaking Spanish or French? I think it would be hard for Moominmama to learn those languages too, though not difficult for me. So, continuing to work is not stopping us from making a move to another location that we could or would want to make.

So, for now not much will change, but this blog will change. I plan to stop reporting actual earning, spending, and net worth figures. Going forward, all numbers will be in percentage terms only. When the vast majority of our net worth was the result of our own work and effort I was happy to report those numbers, and reporting, even though it is mostly anonymously, helped keep us on track. But now that so much of our net worth has not come from our own efforts and we don't have the goal of achieving financial independence anymore, I don't want to report the numbers any more. On the other hand, I'm not going to erase the existing blog.

Our long term goal now is to pass on at least as much wealth in real terms to the next generation as we received from the previous one. My parents also inherited more than 2/3 of their eventual net worth, though they also saved and worked hard to build up wealth in earlier years. They eventually passed on what they inherited.

Perth Mint

The Perth Mint (Western Australian government corporation) looks like the best way to invest in gold. There are no fees for trading or storage for Australian and NZ residents for accounts greater than AUD 50k, though there are fees to trade online. This is assuming that you only want to have an interest in a pool of gold rather than own specific gold bars. Alternatively they have an ETF trading on the ASX with a management fee of 0.15% p.a. (PMGOLD.AX). This is lower than IAU or GLD.

Other alternatives are to actually hold physical gold in a bank vault or trade gold futures. The problem with futures is if the price of gold does go up, you will have to pay short-term capital gains taxes continuously as the contracts expire (and buy and sell contracts every few months). And I don't really like the idea of getting delivered a bunch of gold bars, taking them to the bank, and then paying storage fees.

Gold has historically been a reasonable hedge aganst inflation but only in the very long run. It is actually more useful as an asset that is negatively correlated with the stock market and useful as an emergency fund in a stock market crash.

Target Portfolio

Following up on my previous post where I tested the performance of an idealized portfolio, here are some more ideas about an actual implementation. In total, 50% would be allocated to stocks, half of that Australian and half of that international. A fifth (maybe more) of the Australian category would be allocated to small cap stocks. Of the remaining 20% portfolio allocation half would go into unhedged funds/stocks and 10% into hedge fund type funds, probably mostly listed hedge funds, such as Cadence Capital (CDM.AX). Of the 25% in international stocks, half would go into hedge funds, primarily Platinum Capital (PMC.AX), which pays franked dividends. Then 25% is allocated to managed futures, probably mostly Winton Global Alpha Fund. This should mostly be held in a superannuation account for tax reasons – pay 15% tax on distributions instead of 47%. That means I am going to need a self-managed superannuation fund.

5% is allocated to gold. This would be held in a taxable account as it doesn't pay dividends. On the other hand, the long-term capital gains rate in superannuation accounts is 10% (and zero after going into pension mode) and my current long-term capital gains rate is 23.5%. If Labor get into power, which is likely, and implement their program, which is less likely, that will rise, though in retirement I expect my marginal tax rate will fall back into the 32.5% bracket but with Medicare tax and Labor's proposal, I would still be paying more than 25% for long-term capital gains. So it makes sense to get more money into superannuation, which is zero taxed in pension mode for the first $1.6 million for each partner. I plan to initially invest about $900k in the SMSF. This will come from rolling over my superannuation fund now at Colonial First State and adding $300k - you can invest 3 years of contributions at once - for each of Moominmama and myself.

The remaining 20% is allocated roughly equally to (mostly direct - i.e. not listed) real estate, bonds, private equity, and cash. Then the whole thing is levered up a bit, with the overall exposure adjusted for market conditions. I expect that debt will be roughly equal to the value of our house ($840k).

To summarize, this is the asset allocation (not including our house):

We are quite a long way from that - in particular very overweight long Australian shares and underweight hedge funds, managed futures, and gold.

Safe Withdrawal Rates

Interesting simulations of safe withdrawal rates over longer time horizons by ERN. The lowest withdrawal rate simulated is 3% p.a. Ed Thorp states that 2% is actually the safe capital preserving withdrawal rate. Our current spending is about 2.75% of estimated total net worth including the inherited money. But I expect our spending to continue to increase faster than inflation for a long time to come.

Art and Net Worth

On one of the many documents we've been sorting through my mother estimated her and my father's net worth in 1995. The number she came up with is equivalent to about USD 1 million today (£350k at the time). But she estimated that an inherited artwork* they owned was worth £20k (USD 56k today). The next year the artwork sold at auction for... £750k (USD 2.1 million). Another letter from my father to his brother in 1954 stated that the art had been valued at USD 880 or around USD 8500 today.

*The art consisted of panels like on this cabinet, but not the cabinet itself:

Sorting Things Out

We're sorting through everything in the apartment - first finding things specifically identified in the will to be given to various people. Mostly jewellery and silverware. But also a stamp collection, which I am supposed to get. We found most of them, but not all. Searching through boxes of documents - recycling a lot of routine financial statements and reserving others for further study. There are files and boxes of letters from the early 20th Century and even greeting cards from the 19th Century. Old books, some family books with names in, others that my mother saved from destruction. We are sorting books into ones we are interested in and others to probably give away. We decided to sell the apartment within a year - if we sell in less than 18 months our mother's previous tax status will apply and we won't need to pay capital gains tax. The apartment will need a lot of work to put it into saleable condition. But there is plenty of demand. My brother keeps getting asked if he is going to rent it out. But like me, he is not keen on owning physical assets directly....

My Mother

This weekend I am traveling to the other side of the world to visit the "home country", though it's not the country I grew up in.

Just over three weeks ago my mother died. She had dementia for several years. When I visited in December, things didn't look good, but she went through a few more cycles of getting a little better and then worse again. Still when the news came it was a shock, though it was so long expected. Maybe partly just finally hearing the bad news. I had decided beforehand not to rush to the other side of the world, right away. The custom there is to hold the funeral on the same day if possible. So, I would miss the funeral or hold everyone up. It seemed better to try to go on with life somewhat normally for a little while than inconvenience everyone here to sit on a plane and in airports on my own for two days each way. Now I am going for the ceremony when the gravestone is "set".

I am also going to work with my brother on sorting all the legal and financial stuff out. Things are actually quite well organized, especially as my brother and I managed all my mother's finance and care etc in the last few years, but there are still some uncertainties. My brother will have to handle most of the organizational details. The main  thing I have been involved with so far is paying the termination payment for the care worker who looked after my mother in the last 7 years. Her devoted work meant that my mother could continue to live at home and did not move to a nursing home or hospital. My brother and I shared in making the payment, which includes paying out her nominal superannuation savings - there aren't real accounts for foreign workers superannuation it seems. We transferred the money to her daughter in her home country. My mother's bank accounts are all frozen now until the probate is sorted out, so we have to take care of all these expenses. Luckily we have the means to handle this kind of thing - my share of this payment was equivalent to a few months salary for me - easily.
