I don't think so. That explanation also suggests that the stocks are very cheap (relatively).
Makes no sense to me, particularly given the tax advantages of dividends.
Favorable tax treatment certainly supports the conundrum.
So what is happening? Why are* half the S&P500 yielding more than the 10yrT?
I think a rational argument can be made that corporate earnings have been substantially increased by Federal deficits and that the market is discounting the reversal (lower earnings).
IF that proves true there will be a lot of money made by owning stocks where the earnings rise or hold up better than the general stock.
