Duckfat, the reason Apple is borrowing to do stock buy backs is primarily because of the wonky US tax system. If they repatriate the hoards of cash they have overseas back to the US they will pay a hefty rate of tax on it. Canada has a far friendlier tax system for our multinationals - a canadian multinational that repatriates cash back to Canada will not pay any incremental tax on those earnings (provided the income was earned from an active business carried on in a country that is not a tax haven). Because of the approach the US takes, it makes far more sense for Apple to borrow to do the stock buy back, leave the cash offshore rather than repatriate it, and then get an interest deduction for the borrowed funds. Nevertheless, the cash apple is borrowing (as large as it seems to us - the largest bond offering in history) is peanuts compared to the cash they have.
I agree with you about the average guy being underinvested. When I start to see those folks moving into the market en masse, then I will be leaving it, lol.
