What a finished FIN-451 Topic 4 rebalancing rule cost study looks like
The finished study follows 1,000,000 at 60 percent stocks through returns of 22, 18, minus 20, 12 and 8 percent on stocks and 3, 2, 4, 3 and 3 on bonds, every figure illustrative. Left alone, the portfolio reaches about 67.3 percent stocks just before the bad year and loses about 155,900 in it, against roughly 133,000 for either rebalanced version. The annual rule trades five times and moves about 202,700. The band rule trades twice, selling about 93,400 of stock after the second year and buying about 74,000 after the fall, for 167,300 of turnover. At an assumed 0.10 percent per trade the dollar cost is trivial either way. Tax is not: if stock sales happen in the taxable account, the annual rule realizes about 7,700 of tax and the band about 5,600.
How a FIN-451 Topic 4 example is structured
The study is set out as one path and three rules, then costs, then a caveat. It opens with the portfolio, the 60 percent target from the investor's policy statement and the return path, labeled as constructed for illustration rather than drawn from any market period. A table follows each rule year by year, showing the stock weight before any trade, the trade made and the ending value. A risk paragraph reads the unrebalanced path as a portfolio that drifted toward 67 percent stocks without anyone choosing it. The cost section applies an assumed 0.10 percent trading cost and a tax estimate that treats 40 percent of each stock sale as gain at an illustrative 15 percent rate. A location passage shows that the same trades made inside the IRA cost no tax. The study ends by warning that the ending values belong to this path alone.
One path, three rules
Holding the returns fixed and changing only the rule means every difference in risk, turnover and tax comes from the rule rather than from the market.
Drift that nobody chose
With no rule, stocks climb to about 67.3 percent before the bad year, so the portfolio takes that loss with more equity than its policy allows.
Two trades against five
The five-point band trades only after the second and third years, moving about 167,300 against 202,700 for the rule that trades every year.
Tax, not commission, as the cost
Trading costs come to a few hundred dollars under either rule, while tax on stock sales in a taxable account runs to thousands.
Where the trade happens
Executing the same rebalancing inside the IRA removes the tax entirely, which makes the choice of account a larger saving than the choice of rule.
Ending values read with caution
The band finishes highest on this path, and the study says plainly that a different sequence of returns could reverse that ranking.
Where marks go in FIN-451 Topic 4
A rebalancing rule stated without a price is where most marks go, since a rule costed at zero will always look worth following. Papers that compare ending values alone, and crown whichever rule finished highest, mistake one path's luck for a property of the rule. Counting commissions and ignoring tax misses the cost that actually decides between rules in a taxable account. A study with no unrebalanced baseline cannot show what the rule was protecting against, which here is a portfolio drifting more than seven points toward stocks. Leaving the account location of trades unspecified hides the cheapest fix available. Treating a narrower band as automatically safer overlooks that a three-point band trades almost as often as the annual rule and brings the tax bill with it.

FIN-451 Topic 4 questions, answered
Is a threshold rule always cheaper than a calendar rule?
Not always, but it usually trades less for the same control over drift, because it acts only when the weights have actually moved. On this example's path the five-point band traded twice in five years against five times for the annual rule. A band set too narrow loses that advantage, and on some return paths a calendar rule happens to trade at better moments, so the study reports its result as belonging to its path.
Why does rebalancing inside an IRA avoid tax?
Because sales inside a traditional or Roth IRA are not taxable events when they happen; tax on a traditional IRA arises only when money is withdrawn. A household holding both taxable and tax-deferred accounts can often restore its target mix by trading inside the deferred account alone. The study describes this at a general level and assumes its rates and gains for illustration only, since actual rules and rates change.
Should my portfolio follow the band rule in the study?
The study cannot say. Its portfolio, returns, trading cost and tax assumptions are constructed for a FIN-451 exercise, and the best rule for a real household depends on its accounts, tax position, contributions and the discipline to follow any rule at all. The example shows how the course wants rebalancing rules compared, and a licensed adviser should look at real accounts before any rule is adopted.
