spent some more time looking at the data from last season, and need to clear up a couple of points raised by JoeP. One is that the prices used are from Bet365, and the second is that I do not use Betfair if I am subject to the Premium Charge, but while that was an issue for last season, it isn't right now, with my total charges running at 20.62%. So the prices and the assumed 5% commission can probably usually be bettered, but I prefer to err on the side of caution.

Fascinating -- any conclusions on the reasons? Are the markets more efficient in Italy and Spain? Less attention paid to Germany? Or is it the nature of the football -- Bundesliga being a more open championship than Serie A or La Liga? Whatever the reason, thanks for the blog. Real food for thought with each post.

Certainly, the Bundesliga is arguably more competitive than Spain with Bayern Munich averaging 2.06 points per game last season compared with Barcelona's 2.61, but Internazionale's 2.16 points a game puts Serie A closer to the Bundesliga than to La Liga by this measure. France and Germany are almost identical too, but there are definite differences between these two leagues when looking at the performance of favourites. It's also true that worldwide, there is less interest in German games than Italian or Spanish, but it is still a major league - we're not talking Ryman League here, so it's hard to believe that the prices should be any less accurate than those of the other top leagues. Last season every team won at least two away games, something not seen in the other leagues, and there were some frankly bizarre scorelines which we have already seen again this season (Bayer Leverkusen 3-6 Borussia Moenchengladbach).

Anonymous asked "

What would the total P/L be across all those Leagues?",

and the rest of this post should answer that question. I mentioned that I included the Scottish Premier in my data yesterday, but it really doesn't belong in such exalted company, so I am excluding it from here on.

Backing the favourite in every match in the top five European Leagues would have resulted in a -2.61% ROI. As mentioned yesterday, this strategy would have been profitable in Italy and Spain. Laying the favourite in every game would have resulted in a loss of 1.85%.

I looked at the results of laying favourites at various price ranges.

Laying every odds on favourite would have been profitable only in Germany (25.38%) and France (2.23%). Across all leagues, the total loss would have been just 0.32%.

Laying just those favourites priced at 1.5 or less, and the loss across all leagues would have been 7.19%. Again this would be profitable in Germany (15.68%).

Narrowing the bands down still further, and laying any favourite priced at 1.19 or less would not have been a good strategy - just one winner (in France) from 49 bets for a loss of 86.55%, but if we take these out of the equation, things get interesting.

In Italy, favourites priced between 1.4 and 1.89 are overall value to back, whereas in Spain, favourites need to be priced at 1.7 and above to be value. Laying at prices between 1.3 to 1.69 is profitable, but not hugely. Overall, laying the favourite in Spain doesn't appear to be a profitable strategy.

In the Premier League, laying favourites priced at 1.9 or more is profitable (4.21%).

Overall France is pretty much a wash. Laying all favourites would have resulted in a 1.17% ROI, although favourites in the 1.5 to 1.69 are profitable to lay (33.49%).

That's a lot of numbers to take in, but to summarise, a strategy of laying all odds-on favourites across all leagues would be unwise, but with a few tweaks, it has some potential.

These numbers are from last season only, so too small a sample to draw any firm conclusions from, but just to throw it out there, if we exclude Italy and Spain from our selections, as well as any favourites priced below 1.3, we would have a total of 478 lays, and a profit of 63.47 units (13.28%). Not too shabby.

When time permits, I'll go back to earlier seasons and see if these findings hold true longer term. As I said yesterday, it looks like a low-risk strategy that could easily be quite profitable.


Laying In The Bundesliga


The storm at work has just about abated, and I finally have my life back.

I've written before about how the different football leagues I follow all have their own unique personalities, and this suspicion is borne out after looking at the numbers for last season.

The best league for backing the favourites was Serie A, where 1 unit bet on every match would have netted (assuming 5% commission) 23.89 units. This strategy would also have been profitable in Spain, but a losing idea in France, England, Scotland and Germany.

When I looked at the retuns from a strategy of laying odds-on favourites, Germany was hugely profitable, with a profit of 40.6 units to a 1 risk. Two other leagues were also profitable, but only slightly, while in Spain this strategy would have lost you 27.14 units.

Thinking this might have been something of a fluke, I decided to look at how this would have played out in 2008-09 and again this would have been a profitable strategy in Germany, although not surprisingly by less than in 2009-10.

More work to do of course, but at first sight it looks a promising low-risk strategy.

interesting stuff boat.
would love to know how/where he gets all his betting history from.

boat,
