What are the negative roi horse racing bets?

Question

I am not a big fan of horse racing betting, for the reason that it is too complex for me. I just came across this negative roi horse racing betting term and would like to know, what does it mean? Please specify.

Answer 1

Stats can be used for positive and negative reasons. Not only will they tell you if a type of race is exceptionally good for favourites, or that a particular jockey and trainer combination have returned year on year profits, but they can also point out reasons why you should not be backing a specific horse. These will be stats with low strike rates, and big losses (big negative ROI’s or Return on Investment).

Now if you could find a race where the favourite has a bad record, and the trainer of the favourite is using a jockey who has achieved a low strike rate, and the second favourite is using a jockey with a good, profitable strike rate… you could find yourself a nice bet!
