Describe the existing mix

A hypothetical account contains $900 in shares, $450 in bonds and $150 in cash. Its $1,500 total gives weights of 60%, 30% and 10%. These are descriptive percentages, not suggested targets. The calculation is each category's value divided by the same total on the same date.

If another $300 account is left out, the description is incomplete for anyone trying to understand the combined investments. Decide the scope first: one account, all investments for one goal, or a wider household picture. Changing the scope changes the percentages even when no holding is bought or sold.

Categories require a definition

A mixed-asset fund complicates a simple account-level list. Labelling the whole fund as shares because it is held in an investment account can misstate the exposure. Its underlying mix may need to be considered, using the latest available information and noting when the data were published.

Likewise, a bond fund and a single bond held toward a known repayment date have different mechanics. Broad categories organise information, but they do not replace an understanding of the product. Keep a note of material features that the category cannot express, including concentration, currency exposure and access restrictions.

An allocation changes when the denominator changes

Return to the illustrative $1,500 account. If $300 of new cash is deposited and left uninvested, the amounts become $900 in shares, $450 in bonds and $450 in cash. The new total is $1,800, with weights of 50%, 25% and 25%. The share holding did not fall, yet its percentage fell from 60% to 50% because the total changed.

If the same account instead pays out its original $150 cash, the remaining $1,350 consists of about 66.67% shares and 33.33% bonds. Again, no share purchase was required to increase the share percentage. Deposits and withdrawals belong in an allocation review because they can alter the mix as materially as trades.

A useful review sheet therefore has two views: current amounts and planned cash flows. Keep an upcoming deposit labelled as planned until it arrives. Mixing a future contribution into today's total can make the account appear closer to a target than it actually is. This is an accounting distinction, not an argument for any particular target.

Connect the description to a purpose

The SEC's educational material describes asset allocation as dividing investments among asset categories. It also links the decision to horizon and risk tolerance. No percentage example can supply those personal facts for a reader.

Before discussing a target, write the goal, expected withdrawals and the consequences of a shortfall. Two people of the same age may have different obligations, income stability and deadlines. A formula based on age alone can conceal those differences.

Use a before-and-after sheet when considering a change. Show the amount moved, the resulting weights and any costs, rather than describing a trade only by the name of the investment purchased. That makes it possible to see whether the action increases an existing concentration or adds a different exposure. The educational value lies in seeing the relationship between amounts and proportions; selecting a suitable allocation remains a separate decision that may warrant qualified, individual advice.
