Forex Market Today: 99% Bogus Volume?

leave a comment »

An importer in Europe buying equipment from Japan exchanges euros to Japanese yen — this represents a forex transaction serving a merit of faciliating international trade. But sounds so old school, doesn’t it?  Today forex is probably 99.9% trading for the purpose of trading. To capture trends, to trade patterns, to use as an alternative to casino … whatever, but not to serve real trade transactions.

Accordingly, the forex market should be approached as a subject of mass psychology and algorithmic trading with little relevance to what the underlying instrument represents. By observation, the forex market has got as close to random walk as any other market in history. Will the forex market eventually transform itself, effectively, in casino which depends on constant inflow of new money and where only the house [i.e. broker] makes the money? Recently it doesn’t look a remote possibility. There are a lot of markets which are much more easier to trade [i.e. more profit with less risk] and where random walk is something far from reality.

System trading: Soros paid £1m, you get it for less than $100

leave a comment »

Annual returns in +/- 100% area and corresponding drawdown risk at about 15% is a splendid investment proposal. This is what the best signal vendors offer. For comparision, buy-and-hold S&P stocks strategy has about 10% annual returns with 50% drawdown risk (or more exactly, this was true till Y2008).

Not so long ago such performance would have been dismissed as unrealistic.  Yet track records are independently verified, not dependent on market conditions and the service is available to everybody. The performance is similar to what Nicholas Roditi achieved in the few years prior to Y1998 trading for Soros Fund Management out of his home office in Hampstead, London. Reportedly his annual pay for the work was £ 52 million (i.e. a cool £ 1 million every week). Today the best system vendors deliver about the same performance at +/- $300 per month.

All the facts just scream … it is such a no-brainer that every investors should embrace the opportunities unearthed by system trading. Bank deposits, stocks and bonds seem a game for fools compared to risk/return potential of system trading.

Fundamental analysis in trading system development

leave a comment »

Noticed this post on SeekingAlpha [thankx to forex_gal for the tweet].

This remainded me of my own research done a few years ago. I didn’t know “the he Austrian school of economics that defines inflation as the expansion of money supply”, but my hypothesis were very similar.

My first presumption was that the inflation measure is M3/broad money supply less GDP growth. The idea was that GDP growth increases the need for more money in circulation to service the economy. So, GDP “neutralizes” money supply effect as a inflation-inducing factor.

My second presumption was that higher inflation induces stronger currency. This comes from observation in the currency markets that higher inflation data usually lead to stronger currency. And academic logic should suggest that higher inflation should mean weaker exchange rate as the inflationary currency gets debased by increased money supply (aka money-printing).

The marketplace reality defies academic logic — higher inflation usually means stronger currency (of course, this applies to low-inflation environment only, but not to hyperinflation). There may be a good explanation. Higher interest rates are generally associated with higher inflation, and such interest rates may be a good deal an investors, but a bad deal for domestic population. The catch is that population can not get out of bad deal (higher inflation and interest rates) while trader/investor can switch in an out of the currency instantly. However, in the long run the currency should decline in line with the money supply differential.

The whole methodology is to project money supply differential and plot it against exchange rate. In the long run, the both parameters should converge. In short term the parameters will fluctuate away from equilibrium in one or another direction.

My finding are that the parameters converge fairly consistently for all the major currencies. In Novermber 2007 our reasearch concluded that, according to this methodology, the British pound is overvalued by about 60% and such overvaluation disbalance has been accumulated over about a decade. In Y2008, GBPUSD declined from about 2 to 1.36 at its lowest point.

Can the methodolgy be used for a valid trading system? Hardly. The problem is that even if fundamental analysis correctly determines the magniture of the disbalance, it has no way to tell when such disbalance is going to correct. As in the example above, GBP disbalance accumulated for about a decade before at least partial adjustement took place. As Keynes correctly noted, “market can remain irrational longer than you can remain solvent”.

If you run a multi-billion fund and make massive macro bet on currencies, to have such fundamental analysis for the merit of second or re-inforcing opinion, is a prudent and professional choice. For small traders/funds, it is beyond limit or merit to maintain such fundamental analysis. They are probably better off by just following some trend-following rules. If the price breaks, just go with the trend. More often than not dumb/uninformed trend-following trade will be as good as smart/informed trend-following trade.
