Market Timing Experiment – Update

Apologies for intruding into your inbox. I like to keep the Slack Investor blog folly to twice a month. But these are unusual times.

The Slack Investor Market Timing Experiment

Slack Investor started his ‘index-timing’ strategy in 2004 with the ASX Index, UK Index, US Index. An earlier version of Slack Investor thought that by monitoring the market at weekly and monthly intervals and setting ‘stop losses’ to know when to sell the index. To know when to buy, he used a momentum indicator called the Directional Movement Index.

Although, there was some initial success over the ‘buy and hold’ strategy, the benefits work out to be quite small on a yearly basis. For example, for the Australian Index there is a 1.2% p.a. outperformance for Slack market timing strategy over ‘buy and hold’.

These relatively small gains would have probably been offset by earned share dividends if I was using the alternative ‘buy and hold’ strategy. Market timing works well when there are sustained periods of bull and bear markets and the changes between the two are not too rapid. The short transitions and the speed of market fluctuations in the last 20 years has forced a bit of a rethink on Slack Investor’s timing the markets strategy.

Instead of monitoring the markets monthly, he has been looking for weekly changes as well. He is also taking the current market value and recent trends into account. Slack Investor is a man of routine and he has now decided to keep the experiment going for 25 years (till 2029). After this, he will probably go for the more appropriate Slack Investor method of doing nothing and adopting a ‘buy and hold’ technique for index funds (ASX Index, UK Index, US Index).

US Index – Slack Investor is OUT

At the end of the past week, Slack Investor conducted a review of the Index charts and noted that the US Index price has slipped below the stop loss (thick red line). As the trend is still downward, and the market is overvalued (see below), it is time to get out. As part of this experiment, I will sell my small holding of S&P 500 Index tomorrow and update the US Index page.

What about the rest of the Slack Portfolio?

Deep down, Slack Investor doesn’t believe he is very good at timing the markets. The bulk of the Slack Portfolio (97%) is not in index funds, but in growth companies – that are taking a bit of a beating at the moment. That’s what the stock market does in times of uncertainty.

Mostly, Slack Investor will be doing nothing. He will try and distract himself from the self-destructing behaviour of Trump. I cannot remember a time where the whole world was so united in its resolve against the USA. Slack Investor knows that good times (and prices) will return. Slack Investor has his Stable Income Portfolio if he needs cash.

The worst thing to do, from a long-term wealth perspective, is to convert shares to cash in a down market – _{Slack Investor (and other wise investors!)}

On the back burner is my project to sell some of the Slack Investor owned companies with a relatively low Slack Factor – and invest more in those with a high Slack Factor.
