Slack Investor Market Timing Experiment brings no joy

Slack Investor is aware that there are some people who state that they can ‘time the market’. Marcus Padley, and others, offer such a service to their subscribers.

Slack Investor doesn’t dispute Padley’s claims and has admiration for those who can perform this amazing feat. However, he is convinced that, without following daily, or even hourly, fluctuations in the markets, that this stuff is best left to professionals. The market swings are just getting a little too rapid, short-term and meaningless.

As the result of the China/USA trade talks, the US will lower tariffs from 145% to 30%, while China’s tariffs on US goods will drop to 10% from 125%. This caused the S&P 500 to surge and create enough momentum to trigger the 11-week Directional Movement System (DMS). Slack Investor uses the change in slope of the DMS in his market timing experiment to determine a BUY signal.

Slack Investor’s market timing is below par on the US market and, he will be glad when his 25-yr index experiment, with this small part of his portfolio (<2%), will be over in 2029. On current figures, his market timing for the US Index is 18% behind the ‘Buy and Hold’ strategy. Not very good!

Slack Investor should stick to his strengths

It’s time to stick to things that Slack Investor has been good at. For example, finding profitable and growing companies – that are not too expensive.

In the ongoing examination of my portfolio, Slack Investor has resolved to slowly concentrate the companies that he owns so that they are at the upper end of profitability, growth and affordability. This means a bit of weeding on the companies with a low Slack Factor and, a bit of buying on those with a high Slack Factor.

In the past few weeks, he sold his positions in Macquarie Group (MQG) and Cochlear (COH). Both are solid companies but, they were either, getting too expensive – or slowing down in growth. Both had a relatively low Slack Factor.

To decide what to buy, Slack Investor got off the couch and went to the  Market Screener site to gather information on the companies where he would like to increase his holdings.

Where, PE (2027) is the forecast P/E Ratio for 2027; ROE (2027) is the forecast ROE for 2027); EPS Growth is the forecast EPSG for the next three years (EPSG AV). The Slack Factor is a combination of these metrics using the formula defined in previous posts.

The standouts, with a high Slack Factor, were TLX, SNL, CDA and MP1. MP1 is a newcomer to the Slack Portfolio and hasn’t got much of a track record yet. SNL is a great growing company but is already over 10% of the Slack Portfolio. That leaves TLX and CDA. I bought more of both of these to build up their positions in the portfolio.

Mining for ideas – and April 2025 End of Month Update

Museo – Deep Down In A West Virginia Coal Mine

Mining for coal must have been a tough gig back in 1909. Slack Investor has had it far sweeter in his mining for good companies that have been beaten up by the recent Trump escapades. Sadly, in these lower price times, he is fully invested. But, even after a beating, it doesn’t stop him thinking about possible future investments. Sometimes the best ideas come from other people.

Quality at a Discount

Livewire is a financial newsletter that offers free subscriptions and Slack Investor is a keen reader. Livewire depends on contributors from the financial industry and is always worth a look. An article by Tom Stelzer of Bell Potter caught his eye on April 8, 2025.

Tom seems like an astute fellow and his methods for sifting through stocks rang a bell with Slack Investor. Similar to Slack Investor he combines growth, profitability and P/E Ratio to come up with a stock list – in an organized way. Slack Investor might argue that the method is not quite as elegant as his Slack Factor analysis, However, Bell Potter do have a standard screen for ‘quality at a discount’ – and this seems far less effort.

(Tom) assesses their potential for growth, earnings momentum and looks for stocks with notable P/E compression over the last few weeks to produce a list of 20 quality mid and large-cap companies that are well-positioned and likely undervalued Tom Stelzer, Bell Potter

Slack Investor notes that 9 of the 20 stocks presented are currently in the Slack Portfolio. The above tables were just the first sort. Tom then looked hard for those quality companies that were not overpriced. The Post 12MF PE column (12-month future P/E ratio) was used here.

Bell Potter came up with four companies that they consider good buys after the recent slump – they are listed in the table below. Slack Investor has also provided a further screen by calculating the Slack Factor for each of the companies.

The ingredients in the Slack Factor were obtained from Market Screener. Where ROE is the forecast ROE (ROE 2027), EPSG is the forecast EPSG for the next three years (EPSG AV) and, PE Ratio is the forecast PE Ratio (PE 2027). The Slack Factor is then calculated – a high Slack Factor is usually good news.

Of the 4 recommended Bell Potter stocks. The Slack Factor indicates that TLX and REA are the standout buys for Slack Investor – at the moment.

April 2025 – End of month update

Slack Investor is OUT of the US Index (S&P 500)! He sold his small US Index holding on Monday 07 April, 2025 at 5048. After the rebound, the latest monthly chart indicates this might have been a mistake – and reinforces his belief that Slack Investor has no great skill in timing the market. The 25-yr market timing experiment will continue till 2029. Slack Investor remains IN for Australian index shares, and the FTSE 100 as, at the end of the month, they were above their stop losses.

Slack Investor has never been a huge fan of the ‘American Way’ but did hold an admiration for their ingenuity and general work ethic. I have never seen such wilful destruction of American international standing in such a short time. As well, Trump’s capricious economic policies have the S&P 500 all over the place. The US Index recovered its losses and rose 10.3% since its 10.0% slump early April. Trump is 100 days in … 1461 to go.

For the ASX 200 (+3.6%) and the FTSE 100 (-1.0%), it has also been a wild month.

All Index pages and charts have been updated to reflect the monthly changes – (ASX IndexUK IndexUS Index).

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 IndexUK IndexUS 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 IndexUK IndexUS Index).

US Index – Slack Investor is OUT

Monthly chart S&P 500 up until Friday April 4 2023 – incrediblecharts.com

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.

US CAPE values – up till the end of March 2025 showing the index is still overvalued (at March 31). The CAPE ratio is above the green zone.

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.

The Slack Factor – March 2025 End of Month Update

Reporting Season

During February, most companies report on their progress up to the end of December. There is a similar reporting season in August for the period up to 30 June. Once all the analyst projections for future earnings are in, it is a good time to update the state of play for companies in the Slack Portfolio.

It took a while for Slack Investor to understand that a company could come in with a great report on the business and still, the price of the shares might go down. This is because reporting season is all about expectations. If a company was expecting an increase in earnings of 22% – and they ‘only’ achieved 20%, the share price is likely to get knocked down on the announcement.

As the Slack Portfolio consists of mostly growing stocks with a relatively high Price to Earnings Ratio. The growing stocks usually have high prices as the company’s growth is priced in. These stocks can get punished severely when an earnings target is missed – price falls of 10-20% are not uncommon. But, it is long term results that really count and Slack Investor is willing to endure any short-term pain for a growing company. This period of ‘Trumpenomics’ is an example of such a time.

Slack Investor uses the excellent Market Screener site (requires email registration) to get information from the Financials tab for each company. Analyst information is not available for ETF’s so, only data on the individual companies that are in the Portfolio is gathered.

In the table below, information is listed for the forecast P/E Ratio (PE 2027), the forecast Return on Equity (ROE 2027), the forecast Earnings Per Share Growth (EPSG 2025) (EPSG 2026) (EPSG 2027) and the average of the three Earnings Per Share Growth figures (EPSG AV). There is some fudging of the figures as some of the forecast EPSG figures were unavailable. Also, for some of the companies that are new to profit, their EPSG figures are skewed – I have limited the EPSG (AV) to a maximum of 50. I have ranked the companies in order according to their Slack Factor.

The Slack Factor

What is the Slack Factor? It is well known that Slack Investor likes

  • Profitability – measured in terms of the forecast Return on Equity – ROE 2027
  • Growth – measured as the average forecast Earnings Per Share Growth – EPSG (AV) for the three years 2025, 2026 and 2027.

It is well known that Slack Investor does not like

  • High Price to Earnings Ratios – measured in terms of the forecast Return on Equity – PE 2027. Sometimes, great companies are just too expensive.
ROE is the forecast ROE (ROE 2027), EPSG is the forecast EPSG for the next three years (EPSG AV) and, PE Ratio is the forecast PE Ratio (PE 2027).

So, things he likes go on the top line and the things that he doesn’t like go on the bottom line. This reduces a lot of the complicated information in Slack Investor’s tiny brain to one number. He has made no attempt to scale (normalise) each input into the Slack Factor. It is just a simple way to rank companies with qualities that he thinks are good. The bigger the number, the more likely the company has attributes that Slack Investor likes – profitability, growth and a price tag that is not too expensive. With these traits … surely good things are more likely to happen?

The fast growing Telix Pharmaceuticals (TLX) is a company that Slack Investor is a fan of, and it has a high Slack Factor of 52. The growth dullard Commonwealth Bank (CBA) has a Slack Factor of only 3 – and, is of no interest to Slack Investor.

Over the next quarter, I will try and sell some of the Slack Investor owned companies with a relatively low Slack Factor – and invest more in those with a high Slack Factor. For homework, using Market Screener, try to work out the Slack Factor for some of the companies in your own portfolio.

March 2025 – End of Month Update

The current ‘Trump Slump’ in stock prices can be attributed to the largest upheaval to global trade since the Second World War – Thanks Donald! All followed markets fell this month. The ASX 200 down 4.0%, the FTSE 100 down 2.6%, and the S&P 500 down 5.8%. For now, each Index remains above their stop losses. Slack Investor remains IN for the FTSE 100, the ASX 200, and the US Index S&P 500.

Slack Investor took the opportunity to tighten up his stop loss values for the FTSE 100 and the ASX 200. On the UK Index chart below, by drawing a black wavy line under the monthly minimum values, it can be seen that some new ‘higher lows’ have been established. It made sense to move up the stop loss to the most recent ‘higher low’.
