Feature
Market
Type for the Australian Market
by
Van K.
Tharp, Ph.D.
When you have a trading system, you should always know how it performs
under various market conditions.
We’ve now settled on a market type measure that uses the 20
day ATR (as a percentage of the close) in comparison with its
historic mean and standard deviation to measure volatility. We’re now using the following guidelines:
-
Normal:
Average ATR% plus or minus 0.5 standard deviations.
-
Quiet: Anything less than a 0.5 standard deviation below the
mean.
-
Volatile: 0.5
to three standard
deviations above the mean.
-
Very Volatile: Anything
greater than three standard deviations above the mean.
For the Australian market, I used the Yahoo! data for the Australian All
Ordinaries index (^AORD). Yahoo!
has 6,310 days worth of this data going back to August 3, 1984.
For the 200 day market type, I was able to use 6,110 days
worth of data.
The mean ATR% for those 6,110 days was 1.02 and the standard deviation
was 0.66. This is quite
similar to our U.S. data for nearly 15,000 days of data in which the mean is 1.30 and
the standard deviation is 0.72.
The following table shows the distribution of our 6110 days in these four
categories.

Notice that the more volatile the market, the more likely the price is to
go down, just like the U.S. market. Similarly, the
more quiet the market, the more likely the price is to go up (with
both normal and quiet days being generally up days).
Let’s look at what happens to the market the next day after a given
market classification. Here
we are asking the question, “If the markets are highly volatile on
March 3rd, what is the average percent gain on the
following day (i.e., March 4th) regardless of the market
type that day?” This
data is shown in the next table.

Unlike the
U.S. market, we cannot expect the day following very volatile markets to
be up.
Now let’s combine our five market types (defined last week) with our
four volatility types and see what we can expect.
In this case we are using the 100 day SQN™ on the daily
percent change to determine market direction. By the way, some of you have asked and I’m simply looking
at the daily percent changes in the index and calculating an SQN
based upon that (rather than R-multiples).

What’s a little bit different about the Australian markets is that
strong bear markets occur most often under normal volatility
conditions, even though very volatile conditions are only likely to be
strong bear markets. Bull
markets, however, still occur primarily in normal or quiet markets.
Let’s look at our total market type and the average
percent
gain/loss that is likely to occur under each market type condition.
This is shown in the next table.
There are no real surprises here.

The data are pretty much
as expected except for the volatile strong bull
percentage change being down. However, this only represents 5 days or 0.08% of the
total
days.
Some
History
Now let’s look at the last year’s worth of data on market type.
I’m going to use the 100 day SQN to determine market type,
but I’ll show you the 200, 50, and 25 day SQNs as well. Remember that I use the following SQN ranges to determine the
market direction, so you can translate the other SQN days to market
types.

The data as of Friday’s close is exactly the same as the
U.S. data for the S&P 500.The 200 day is bearish, the 100 day is bullish, the 50 day is
neutral, and the 25 day is bearish. The market type in the last two
columns is based upon the 100 day SQN.

I'll be looking at up to ten other markets. Next week we’ll look at the German DAX index.
When I’ve completed the ten markets, I’ll report on all
ten once each month, probably on the 3rd week of the
month.
