Addendum: I say you're "locked into" a bond here because most people don't consider the possibility of selling bonds (i.e. they plan to hold to maturity). However, you can sell most bonds (not directly back to the issuer but to other people). This may make the similarity between funds and ladders clearer. In the scenario 1 example, if you were to sell your bond, it would also be worth ~$99 (using the same argument as in scenario 2). In other words, the fact that you don't think of this as a loss if you don't sell the bond doesn't change the fact that the bond lost value (the comment by ThrustVectoring further down this chain says this well). If you assume the market pricing of interest rates is fair and that the market is perfectly efficient (i.e. no transaction fees, management fees, etc.), then the expected value of holding, rolling, or investing in a bond holding fund is all the same.
