You cannot compare apples with oranges.

Comparing shares and horses is not logical.
The more people buying shares the better for shareholders, the more people betting on a horse the worse for existing ticket holders.

1. If 10,000 people go and buy plenty of shares someone has recommended - what happens?
The share price goes up -bigger profit for existing holders

2. If 10,000 people go and bet on a horse - what happens? The dividend shrinks - existing ticket holders (excl fixed odds) have their dividends slashed and they either win less or lose.

If someone had a method to pick a good share of winners at good odds - they could make a good tax free income of say $1,000/week.

Why would they try and sell their system and make a ST gain of say $50k or $100k and have consumer affairs and ACA chasing them, when they could make a LT gain of 10 times that???
