When A Good Price May Not Be A Good Bet


What does a late drift in price mean? How should we account for it in pre-race analysis? Today on the blog Declan Meagher tells us.


There was a time before the arrival of Betfair, when if you priced up a race, and 6/1 was available on a horse you thought should be 4/1, you had a bet. Providing you had put in the effort, and analysed the race thoroughly, you should make money taking the 6/1 without too much further thought. While you can still make money this way I believe you need to ask further questions before you strike that bet.

In the pre Betfair days you were mostly just pitting your opinion against a sole odds compiler, who may, or may not have consulted his colleagues on the price. He likely priced up many races that day, and is unlikely to have given the same time to the race in question as you have. That will still be the case these days, but now the bookies also have the Betfair market to guide them, and thus quickly correct any ricks.

The Betfair market at the off is the collective opinion of some very shrewd people, and some not so shrewd, but overall it’s a very good guide to a horses chances. It’s my opinion that, if in the minutes before a race, you think a horse is a good price and that the market has it wrong, you need to know why it’s wrong before you strike a wager.

Too Big A Price?

You hear the line ‘it’s too big a price now’ many times from pundits on TV, and I’ve said it myself, about a horse that took a drift in the market. I think if you weren’t going to back it before the drift, you shouldn’t back it after the drift, unless you're confident you know the reason why it drifted, and have accounted for it in your prices.

The market near the off has some significant sums of money floating around and won’t suddenly move without good reason, if you don’t know the reason then just accept someone knows something you don’t know, and keep your money in your pocket. This won’t always be the case and there are some drifts and gambles for no reason, other than the sheep effect, but if you can’t tell which is which then you’re only guessing.

An Example

Say I made a horse a 2/1 shot and it was 3/1 thirty minutes before the race. I would back it at 3/1, but let’s say I hadn’t had my bet yet, and it drifts to 9/2. I would still back it under most circumstances, as I can account for the new information by also moving my 2/1 estimate out to 3/1.

The 9/2 is still an attractive price. If however I made the same horse a 3/1 shot and he drifted to 6/1, I won’t be backing it. Thirty minutes before the race I agreed with the market on the horses chances, and now it’s doubled in price, unless I know why this happened I can’t justify a bet.

Who's Right? Who's Wrong?

It’s not just drifters that you need to ask ‘why I’m right and the market is wrong’, you should do it with every bet. If you price up a race and find a few horses that the market has at bigger, don’t blindly back them, without at least checking to see if you missed a piece of information that could account for the difference. Could you have misinterpreted the horses form? Do you tend to overrate that type of horse? Always look for flaws in your prices before committing to a bet.

The best bets will be those that you have a very good reason for your opinion - why you’re right and the market is wrong. Maybe you’ve an angle based on your own form ratings or sectionals times that has proven to be profitable in the past. Perhaps you know the horse switching to soft ground for the first time, is very likely to go on it because of sire stats and you also noted it had a high knee action. If this is not reported by spotlight in the Racing Post or on the TV then the market will very unlikely have fully accounted for it.

These are just examples, there are many angles you could exploit and when you have a good one you’ll be able to answer the question ‘why I’m right and the market is wrong’ with enough conviction to get your wallet out and have that bet.
