Quarterly Strategies Review: Winners and Losers

Quarterly Strategies Review Winners and Losers

What a quarter it's been in the markets. The FTSE has had a good run gaining 7.1% and equity investors everywhere have started licking their lips over the gathering momentum in the wake of further lashings of quantitative easing around the world. When stock markets go up, there are stocks, sectors and strategies within them that do even better. As it's our mission to highlight what works when in the markets, let's take a look at how effective Stockopedia's model portfolios of the Investing Masters have been performing.

We keep hammering home at how important it is to use quantitative investing tools in your investing process. Instead of listening to brokers, tipsters and rumours and being swayed by the Siren song of the stories they sell, using a dispassioned common sense stock screening process can help impove the gullible, emotional and easily influenced human decision maker at most of our cores. Learning to defer (or at least listen) to the 'quant' can often help to improve profits in tough markets such as those we are seeing today.

Stockopedia beats the market again

Our 3 month performance can continually be tracked at this link, and as of the time of writing we can see the continued strong outperformance of some classic investing strategies. 72% (43/60) of our long only strategies have beaten the FTSE 100 with gains of between 7.1% and 23.4%, while all 5 of our short selling strategies have beaten it on the downside - again indicating how important it is to avoid fundamentally weak, near bankrupt stocks with potentially dodgy earnings - no surprises there!

At the top of the tables it's been a story of quality, dividends and contrarianism trumping growth and momentum but for how long that remains to be seen.  We have just rebalanced our model portfolios which we do every quarter, so lets take a closer look at how they've done.

Contrarianism and Dividends pay

One of the best books on my investing table is David Dreman's Contrarian Investment Strategies - it's a massive font of evidence that shows that buying cheap, out of favour stocks just works so incredibly effectively. Is it such a surprise that two of his very unfashionable strategies have been the top performers over the summer with gains of over 21% in 3 months?

Our 3 month performance can continually be tracked at this link

Surely this is reviewing results with the benefit of hindsight? When I drill down though the links, what I find is a selection of stocks that each screen currently throws up. To be valid, we need to see what stocks were selected at the start of the relevant period.

If you want to show the performance of "model portfolios", you need to state what those portfolios are at the start of each period, and when and how they are revised.

Or have I missed or misunderstood something?

Hi Mark - I think you may misunderstand our approach. Our results are tracked in real time - these are charts and performance histories of the portfolios of stocks that qualified for the screen criteria as of the last rebalancing date.

Screens are rebalanced quarterly and then held (and tracked) in the model portfolio until the next rebalancing date. The portfolios have been rebalanced several times now - initialised at our beta launch in mid-December, then rebalanced in mid-March, mid-June and now in mid-September.

You are right that each screening page daily shows the currently qualifying stocks for each strategy - these may or may not be currently held in the model portfolio currently used for tracking performance. Currently they are close matches to the portfolios as we've only just very recently rebalanced, but as we drift towards December the lists will diverge until we rebalance again.

I should also mention that many 'backtesting' solutions actually suffer from hindsight bias and survivorship bias. Most databases do not continue to list stocks that fall out due to bankruptcies etc - any backtesting based on them will thus have an upward bias in their results (survivorship bias). Our model portfolios do not suffer from this as they are live tracked portfolios based on the actual database as of the rebalancing date. If stocks fall victim to bankruptcies etc the portfolio takes the hit as of that date. While this is certainly more admin on our part it makes for a far more authentic illustration of the kinds of returns on offer.

Hope that makes it clear and thanks for keeping me on my toes!

Thanks Ed,

But how can I see what the model portfolios actually were/are, as opposed to what the screens currently throw up?

The portfolios have always been publicly available to subscribers on the screening pages so there's no secrecy there but we aren't currently publishing the historical transactional record.  It's all in the database and we may publish the histories in future on the screening pages as a kind of "public portfolio" - though that's unlikely to happen in 2013 due to other near-term development commitments. I assume you want to know the key drivers of certain screen returns? Are they driven by single stocks, small caps, micro caps and so on?

It varies screen to screen, but as a general answer, I would say that some of the most surprising names can be key drivers of quarterly returns and often outperformance becomes isolated to just a handful of unexpected stocks in each list. Joel Greenblatt once wrote a great blog post about his Magic Formula in this way. He found that often people want to pick out their favorites off each candidate list, but by doing so, they often don't pick the seemingly very unfavorable stocks that actually generate the lions share of the returns !

I think I understand how the screens work and the usual comments that DYOR and "Past performance not indicative of future returns." and "results [are] candidates for further research, not as a buy list". As suggested, I did cherry pick my stocks from the list, trying to go for a "healthy" selection. But I reckon it involves emotional bias and is not as manual I'd like it to be - and I may see better (or worse) results this way. Re: the Magic Formula it sounds to me that the list IS a buy list, after all (or intended to be).

I bought most of my stocks 3 weeks ago (not using the Magic Formula alone but did pay attention to it) and after that almost all stocks started to decline in value, I put it on the general FSTE decline (has the new ISA money depleted?). I probably shouldn't worry (yet) but I still can't put my worry aside that I did buy at the top.. I have two suggestions:

The "New Screen Ideas" is a great tool. My worry is that although the stocks are updated daily on the screens, I have no idea for how long they have been there. As most screens do not seem to care too much about the actual price (unless through some indicators like P/S or P/E), I cannot know if I have missed the boat or not. Therefore, it would be great to see WHEN the given stock was added to the list (and here I am referring to the list which is updated daily).

The other idea was to be able to see the selections for the current quarter (i.e. the list that drives the chart), as suggested above. I understand that it is no secret -- however it is only true IF you take note of the actual lists on the actual rebalance date. A week later things might have already changed.

Thanks for the feedback - I've set up a ticket using the Green Help & Feedback button on the right to discuss it with you in more detail. That's the best way to give us product feedback, just FYI for the future.

+1 on the request to have a 'date added' for when stocks join the screen. Had a brief discussion on the subject some months ago with Ed, I believe. Would be so useful

Edward Croft

CEO at Stockopedia where I weave code, prose and investing strategies to help investors beat the stock markets. I've a background in the City and asset management but now am more interested in building great stock selection tools for the use of investors online.   Traditionally investors online have had very poor access to the best statistics, analytics and strategies for the stock market and our aim is to set that straight.  High Quality fundamental information has been prohibitively expensive in the past and often annoyingly dull. People these days don't just want to know the PE Ratio and look at a balance sheet. They expect a layer of interpretation over data, signal from noise and the ability to know at a glance whether a stock is worth investigating or not. All this is possible using great design and the insights gleaned from quantitative research.  Stockopedia is where we try to make it happen ! more »
