Interesting hypothesis. But here I'll speak for myself: usually the TAT price follows the full share price pretty close. Even if I'd be interesting to look at one month period, I'm pretty sure the TAT price will catch up with the other one in this period. So without any consideration for dividends, I'd buy them now. They will rise at least to catch the other... I just did a bit actually, with what I could afford.
well, I have a bit of both, and I've been watching both for some time. And yes, the share prices tend to be a lot closer than this, that is why I mentioned it.
And you'll see why in a bit, as soon as the AM-PT pays out the dividend...
People have a limited supply of btc, and they want to invest the whole amount of BTC, not just whole shares. They are not looking at an annual timescale, for the most part. So, with those 2 things combined, the share prices tend to stay a lot closer, and when the gap widens, there is opportunity for profits.
Now, you cant really arbitrage in the true sense, because you can't trade TAT shares for AM-PT shares. But, you can still earn profits from a gap like this.
