OK, so, yes, I get the concept of free shares. Where I think a lot of investors (or, if you are here, speculators) get twisted up is that they trade their "free" shares differently than those they "paid" for. Whether they are free or paid for, today they have the same value.
I'm reminded of a friend of mine who found a 20 dollar bill which he used to buy lottery tickets. He never buys lottery tickets. But somehow, he thought of that 20 bucks differently than 20 bucks he earned, and spent it differently.
Trading your shares differently based on what you paid for them is irrational. And that's where, to me, the idea of free shares falls off the tracks.
