Yes, there more plenty more factors affecting the share price difference than just the dividend difference. But in the conversation you were responding to, the difference of opinion wasn't about other complexities, it was about what difference the 5% reduced dividend should make to the share price, and Velacreations was mistaken on that point.
I don't think I am mistaken, actually, mainly because with higher volume, you don't see that gap between the 2, so obviously the market doesn't value the 5% fee in the same way you do. I think the discrepancy has to do with time scale and smaller investment levels. Also, we are ignoring the fact that when AM-PT pays out dividends, the prices balance (people use TAT to reinvest remainders)
Let's say, I wanted to own AM for a month. During this month, I expect dividends to be .025-.035, let's say an average of .03 per week. I have 5 btc to spend. Let's assume share price remains stable during this time.
I can buy 1 AM1 shares @ 4.44699 btc right now.
I can buy 104 AM100 shares @0.042765 btc/each right now, for the same amount of btc
At the end of the 4 weeks, I've made the following profits:
AM1 - .03 x 4 = .12 btc
AM100 - .0003 x 4 x .95 x 104 = .11856
that's a 1.2% difference in profit (advantage AM1), and assumes the price gap remains (historically hasn't been this bg). If the gap closes a bit, advantage goes to AM100, as your overall value will increase, despite the 5% fee.
If you go the route of thinking "what would make the most of my 5 btc?", then TAT is the obvious winner, and even with the fee, you would earn more btc for the same time period because you can buy more shares (116 vs 1).
IMO, 4% gap is too big, and is not supported by the share history or time scales most small BTC investors are looking at.
tl;dr - I'm right, when you consider shorter time scales and small amounts of btc
