It's Valentine's Day, which means people are only thinking about one thing... savings bonds! Ok, so it isn't that romantic. But it's a topic worth thinking about given that the U.S. Treasury is pushing investors to put their tax refunds into savings bonds. This certainly helps the Treasury, but is it a good idea for the investor? According to this article from CBS Marketwatch, probably not. Rates are just too low, and there are plenty of other options for investing your cash. If you're among those thinking of following the Treasury's advice, this article - and the comments that follow - are worth a read.
