Myth: “You must bet horses that get bet down from their morning line.”

We've all seen it — an 8:1 morning-line horse is 3:1 at post time. Is the “smart money” telling you something, and do those horses win more and pay you back?

The claim

When a horse's odds drop hard from the morning line, insiders know something — so you should follow the money and bet it.

What we tested

Four-and-a-half years of Saratoga races (2018 through August 2022) on fast dirt and firm turf, with the morning line adjusted for scratches so we could compare it fairly to each horse's final odds. We sorted every runner into three buckets: bet down (final odds well below the morning line), drifted up (final odds well above), and everything else.

What the data shows

Half the myth is true: the betting pool is a better predictor than the morning-line maker. Horses bet down win more oftenthan their morning line implied; horses that drift up win less. So far, so “smart money.”

But here's where it falls apart: big swings in either direction produce significantly lower ROI.Why? They're overbet. One gambler throws a few bucks at the 12:1 drifting to 30:1; another piles on the 6:1 being hammered to favorite. Both reactions distort the pari-mutuel — and quietly drain the value out of the very horses everyone's chasing.

The verdict — BUSTED

You'll cash a few more tickets blindly following horses that get bet down — but you'll be betting into a losing-ROI group the whole time. Don't chase the “smart money” or the longshots floating up. Bet what a horse is actually worth, not which way its odds are moving… unless you genuinely know something.
