What seems bogus is how this never holds gains. No wonder there is so much daily volume. Of course at this point in the interest rate cycle this is a risk even holder longer than a quarter. Who can afford to take a large position here to get that yield?
AT&T may only have 6% but you can sleep at night knowing it's a growing company. You will get you 14% over there in yield and growth over time. In here even the 14% is shaky in the long run.
If you want to test that invest equal amounts in both stocks hypothecally at the day this IPO'd. reinvest divs on both and account for cap gain rates which you get with T's divs (you don't get them here). You will find if you do the calculation T is ahead of this.
The yield isn't the whole story and many are fooled by it.
