The Magic Formula Investing Strategy was published by Joel Greenblatt in his book "The Little Book That Beats The Market" and the updated version "The Little Book That Still Beats The Market." In this video, U discuss why the magic formula screen no longer works and has delivered somewhat disappointing returns between 2005 and 2020. I will explain why the magic formula investing approach has weaknesses and discuss whether the formula is broken.
In the book “The Little Book That Beats the Market”, we can find a table which illustrates that an investor that stuck to the magic formula investing strategy for 17 years, would have achieved an annual return of 22.9 percent. But ever since the book was published, returns have been less impressive.
The American Association of Individual Investors shows that the Magic Formula strategy “only” delivered an annualized rate of return of around 6% ever since Greenblatt’s book was published and thus underperformed the S&P 500 and other benchmarks by quite a bit.

My personal thoughts on why the magic formula has underperformed is because of this ridiculous bull market for the last 10 years. Magic formula investing is a play on value investing, and value investing has simply not returned the same value as growth stocks over the last 10 years. Possibly this is due to the influx of new day/swing traders, at rates that make the late 1990 seem insignificant. My guess is that results will pick up after a recession that takes away the desire for swing traders and growth stock

This may have been an update after the release of the book, but I have seen multiple references to Greenblatt saying that, if a stock is still on the list after the year point has been reached, an investor should consider continuing to hold the stock for another year. That definitely doesn't completely address your stated concern, but I think it is a notable distinction.

The formula is for thoughtless rule based execution that someone with no interest in the companies can execute.

High returns on capital for many years would be one way to screen for these firms but that's just one piece of the overall investment puzzle. I recommend reading the book 7 Powers by Hamilton Helmer.

Nice video, René. Some years ago I tried some value quant strategies (magic formula, TAM, Net Nets). I think the idea is interesting (I mean, buy a quality stock at a cheap price), but these kind of strategies (for me) are difficult to hold. It’s psicologically difficult to own companies you really don’t like. I prefer to think like a business owner and not like a statician.

I bought 14 stocks relatively blindly based on the magic formula to gather some data of my own. I bought the first 7 on 10/13/20 and the second set on 11/6/2020. The first 7 were all companies that were also in the Smp 500 and the second set were smaller cap stocks. The first set are currently up 5% not bad for a normal year but this 2020ish and a share of voo I bought around the same time is up 15% The second set has preformed better up 48% so far. A large part of this is because 2 of the companies are alternative fuel companies, which have seen a massive run up post election. Obviously this this a very short period of time and should be taken with a massive grain salt.

Having a quantitative aproach to your investments is a great way to stay calm and not become to emotional and fail due to our biasis, but you can not just simply blindly pick your stocks, because more often than not one simple look at the companys buisness and/or history, would reveal, that it had one or two good years followed by very medium to poor years.

The big problem is AAII's screener and database is quite different to the original Joel Greenblatt formula and database. AAII uses their own proprietary stock database called something like Stock Investor Pro. Joel Greenblatt used CRSP, I think. And, AAII has a different formulation of the formula. Unless AAII can run this screen back in that same time period and replicate the returns of the book, I would disregard it.

I don't find what happened that strange. The author mentioned it does underperform during bull markets. I think that is what we have been in for most of the years since the book came out. Value investing is like that. To really make the big money from that style of investing you need a long time frame including bear markets. BTW it's my favourite type of investing.

I think this analysis would be different if you looked at investing into the magic formula outside of the US (equally as investing into value stock outside of the US) and maybe this could be a topic for a follow up video. =) Although just anecdotally, my investments over the past year (in Europe) have at least over-performed the index.

Hey Rene, in your video you mentioned that 1-yr ROC isn't strong enough but rather we should ask can the company maintain strong ROC in the long term and the best filter for that is asking if the company has a strong MOAT. My question is, if every 12 months we run the magic formula again and keep companies that have maintained a strong ROC (a criticism you had against selling all holdings after one year which I agree) and then add new ones with stronger ROCs (selling off ones that fell off the list), wouldn't that negate the reason to identify MOAT because we are continuing to revise our portfolio along high ROC companies each year? Perhaps I don't understand soemthing but would appreciate your thoughts. Thank you

Very interesting content, thank you. Besides all you said (which I agree with) I also have a problem with Greenblatt's way of using pre-tax (instead of after-tax) operating profit, i.e. EBIT instead of EBIT*(1-tax rate). I understand he wants to compare the merits of the companies irrespective of the taxes they pay. This shouldn't matter if all the companies operate in the same country (the US). However, I invest in Europe, and tax spreads within Europe is a reality. Considering two equally well-run companies A and B, A being French and B being Irish, B will reward the investor better than A does, that is a fact. So if I want to choose the company that will reward me best (as opposed to awarding medals to the managers), why shoudn't I take the tax rate into account (the result being choosing B instead of A)?

good afternoon, interesting video, only there are a few nuances. how correctly people interpret and use the magic formula and the site of the same name, and do not compose their custom portfolio assemblies only on the basis of this sample. For example, I did not take all the companies recommended on the site, the balance of the sample of companies in the portfolio among themselves was important for me, because some companies immediately dropped out of the sample because they did not fit at their high price. For example, you have 1000 $ and you need to invest it in a sample of companies numbering 20-30, 1000/20 = 50, i.e. the share of one company can no longer be more than $ 50. This is because everyone has their own criteria for the selection process according to the magic formula, and the criteria of different users are superimposed on Greenblatt's criteria. Therefore, the results of investing according to the magic formula can be different for different people at different periods of time.

There is nothing wrong with the screener. But the "HOW TO USE IT" was oversimplified. It should be used in conjunction with your preferred technical trading strategy. One can't just enter positions haphazardly and hope for the best. Either buy positions that already started an uptrend and get out when the trend changes, or buy oversold positions that are crashing and get out after the next bounce once you book a decent gain. Exiting with a 2% gain in 5 days for example is totally acceptable. It's not a good idea to buy anything at anytime, then hold it for a year and hope for the best. Irrespective of what screener the positions fell out of. Timing is always important, even with undervalued companies. Because sentiment wins out over fundamentals most of the time. Cut your losses short if the position turns against you and let the winners run till the trend changes. Why would anybody hold a position for a year and see it drop 50% or more in price is beyond me. 10% is a max loss on a position one should tolerate before getting the hell out of it. Nobody wins them all. Some losses are inevitable.

Another thing to look at is dilution and eliminate companies that are net diluting the public shareholders.

the first thing that I would ask is if those results shown in AAII are trustworthy or not?. Since your premise that the magic formula is failing is basically that you trust in the results portraited in that web site. Honestly, if they dont show me how they applied the concept of the magic formula in their computing systems, it is very hard for me to trust in those results. In my humble view, I only trust in the data provided by the "Little book that beats the market" even if it is outdated.

Fair point. I've seen similar stats though and it shouldn't be surprising that during a period of growth stock outperformance, "value stocks" on average performed rather poorly.

AAII uses different calculations than the one greenblatt uses in the book

I read the book, the Appendix he explain the formula he actually used. It's very different that the one he mention in the book. It was hard to find the right information in the income statement. If you could explain with real examples of stock how to calculate the real magic formula showed in the appendix, I would greatly appreciate. Why the formula does not work. I see 2 reasons: the market on some stocks are speculative, they see TSLA as the future, no matter the numbers, even the CEO say the business is almost bankrupt. But still people make alot of money with TSLA. The 2nd reason is that it focus on the past data, can't predict the future. I would add a 3th one, the stock pick does not use any technical analysis. But if you combine both, you could get a winner. Choosing good company, at bottom and sell at high. But just buying stock because they are the one the computer choosed and sell them in 1 year for just because it's what suggested make no sense to me. I think the maket is changing, because investors are changing. A younger generation that trade with commision free think differently.

the market will eventually crash. That will chase a lot of these newer, speculative investors. Value investing is not dead, as the author explains in the book you have to gauge over the long term. The current market has some similarities with the market just before the dot com bubble and the more recent financial crisis.

Why financial institutes are excluded in magic formula?

@jelledehaen8856 3 жыл бұрын

Very intersting video, thanks! I use the magicformula as a screening tool as well, but have only bought a couple companies based on it. I wonder how the magic formula would fare, if you add some very rudimentary extra screeners. Some companies on the list seem to be in dire financial conditions. Intuitively I would think that if you exclude those companies, the formula would become more effective, because you can't buy the biggest losers? Or do you think that the reverse is true, and that those companies are actually the ones with the biggest upside?

No, I would agree with you and think that assumption is correct.

I think it's because of the formula picks stocks vulnerable to macroeconomics. The global environment is different than it was in the 1970s-1980s

Question is if we look at full data does it still perform better or worse? Hovewer difference between investing in 20 and 500 stocks is much bigger volatility. You're much more likely to have bigger loses and wins than market. imagine if you picked just one stock 10 years ago let's say it was apple you would have huge return. Doesn't mean you beat the market you basically got lucky. So I will just stick to index funds. Everything else cannot be trusted.

I would not agree with you here. I agree that a lot of people will be better off by just investing in an index fund. However, if you know how to carefully choose high-quality business and know when they are able at a bargain price, you should do this. While there is some luck involved, the majority of your long-term performance as an active stock picker will be based on your analysis and behavior during downturns.

Personally, I think the magic formula is a bit misunderstood. I believe it is a statistical way of exploiting the return-to-mean effect. This matches up with Greenblatt's experience that people will have poorer performance if they start to manually pick from the stock screener, i.e. the best effect can come from a seemingly lower quality stock. This is also why it makes sense to not hold longer than 1 year, since you are just hunting the return-to-mean effect. Also, Greenblatt has been very clear on that the magic formula will have periods with poorer performance. If not, everyone would be doing this. However, if you are hunting the return-to-mean effect, I would think you want a lot of volatility. I believe the period after the book came out has had lower volatility, which might be the explanation of why it has not done as well as earlier.

I feel you are engaging in the gamblers fallacy/ sunk cost fallacy when you advise letting stocks run when you have held the for a year and not seen profit. The desire to fiddle with quantitative strategies outputs based on subjective qualitative metrics. generally takes away their greatest strengths and that is how they bypass human irrationality and fragile temperament. Happy investing.

Greenblatt disclosed that he did rolling periods, not calendar years. He also stated that it would not work for years on end, sometimes. He also stated that an investor should do some research into the companies and he said to hold fewer stocks, not 50. I read the little book that "still" beats the market, so perhaps it was expanded upon more in that version of the book. It is a screening model more than a quantitative model. If someone were to buy married puts for those investments, it would have slayed the returns of the overall market.
