Ever wonder why your bond fund seems to move even when the yield looks boring? Here’s the scoop: funds like iShares MBS ETF (MBB) aren’t just about that 4% payout. Most of the action comes from price swings when interest rates change. So, if you’re in it for steady income, remember: rate rollercoasters can mean gains (or losses) too. Also, watch those fees—Vanguard’s similar fund is even cheaper, and that adds up over decades! #Business #Market #Investing101
