Investing - Theory, News & General • Re: Explain target-date bond funds to me like I'm 5

My question is whether target-date bond funds work the same way - and if not exactly the same way, how are they different from buying an individual bond?

You ask a good question. I think it can differ depending on inflows as you say. If rates rise and there are inflows, I believe previous fund holders will see an increase in their dividends. Conversely, if rates lower and there are inflows, previous fund holders can see their dividends lower.

Similarly, aside from dividends, how closely can I expect the amount I receive when the fund liquidates in 2036 to match the amount I invested today? What could cause the two values to differ?

Well if the fund buys bonds at a premium (inflows or index changes or whatever), you would get less at liquidation. That, though, is offset by the higher dividend yield of that bond. And conversely the liquidation amount could be higher if the fund buys at a discount. In which case, the dividend yield until that point would be lower.

Also, there could be credit downgrades and forced sales if the bonds fall below the fund designated quality requirements. That'd likely be a sale at a depressed price. But that perhaps can be looked at as a feature of corporate bond funds. You aren't, mostly likely, going to continue holding the bond as the company goes bankrupt. And if it is sudden and you do, at least it is a much smaller fraction of your holdings.

And surely there will be some small cash drag as bonds mature before the liquidation date. It's probably held in a short term safe vehicle that may pay less than the 10 year bond that just matured did.

I haven't held any of these types of funds to maturity and certainly not over differing rate cycles and inflows/outflows and so have no experience to say by how much the dividend and liquidation value would differ. I wouldn't expect it to be radically different and that depending on your holding time, it could be a slightly better or worse than an individual bond.

For corporates or munis, the credit diversification seems a blessing. For TIPS, it solves the phantom income dilemma (which in an irrevocable trust would allow distribution of the inflation adjustment to the beneficiary instead of having that part be taxed at trust rates).

And for many, it's convenient to be able to add in less that $1k increments.

But no, I don't expect these funds to have the mathematical precision that individual bonds would.

Finally, if a 5 year old understands this I would suspect they are not typically developing and you should seek the advice of a medical professional because genius in one area may come at the expense of deficits in other areas.
