It has two components that can fail to align: tolerance, how psychologically comfortable the investor feels with their portfolio's swings, and capacity, whether they can afford, financially, to wait for a drop to recover without putting their goals at risk.

Earlier levels taught you to understand each asset class separately -- stocks, bonds, ETFs, investment funds, commodities, currencies, all already covered in Level 1 -- and, in Level 3, to value an individual company. This level takes a different step: it doesn't analyze one asset at a time, but how to combine several into a coherent portfolio. This lesson introduces the first and most important decision in that combination: asset allocation.

\n

Asset allocation is the decision of what percentage of a portfolio goes to each asset class -- for example, what proportion in stocks, what proportion in bonds, what proportion in available cash. It isn't choosing which specific stock or which specific fund to buy within each class -- that's a later decision, with less impact on the final result. According to numerous portfolio management studies, asset allocation is the decision that most explains a portfolio's long-term result, more than getting individual securities right within each class.

\n

The reason is that different asset classes behave differently in response to the same events: a stock and a bond don't react the same way to an interest rate hike, and their risk and return profiles, already covered in general terms in Level 1, differ from each other. Combining several asset classes in the right proportions is, therefore, the main lever for adjusting the risk and expected return of an entire portfolio -- far more than trying to pick the "right" stock or fund within a single class.

\n

What determines the right proportion for a specific investor? Two factors, developed in the next two lessons: how much risk that investor is willing and able to take on, and when they'll need to get that money back.

\n

Example

\n

Two portfolios of the same size can have very different compositions: one with 80% in stocks and 20% in bonds, and another with 40% in stocks and 60% in bonds. Neither is "the correct one" in the abstract -- both are valid asset allocations, each suited to an investor with a different risk profile and time horizon.

Objectives

\n

By the end of this lesson you understand how an investor's time horizon and liquidity needs should influence their asset allocation.

\n

The two previous lessons introduced asset allocation and the investor's risk profile. This lesson closes the module with the second major factor shaping the right allocation: time horizon, already covered in Level 1, together with the investor's liquidity needs, already covered in general terms in Level 1.

\n

Time horizon is the period during which an investor plans to hold an investment before needing to get the money back. A long horizon gives more room to take on more volatile assets, like stocks: even if they suffer notable drops in the short term, there's enough time for them to recover before the investor needs the money. A short horizon reduces that room -- a drop right before needing the money may not leave time to recover, so a more conservative allocation, weighted more toward assets like bonds or cash, is warranted.

\n

Liquidity adds a distinct nuance to time horizon, it doesn't replace it. Even if a portfolio's overall horizon is long, an investor may have short-term liquidity needs -- an emergency fund, a planned expense in the coming months -- that need to be covered with liquid, low-risk assets, regardless of how the rest of the portfolio is allocated. "This portfolio has a long horizon" isn't the same as "all my money has a long horizon": it's worth setting aside a liquid portion for near-term needs, and leaving the rest invested according to the investor's real horizon and risk profile.

\n

This completes the module: an investor's risk profile -- how much uncertainty they can tolerate and take on -- their time horizon -- how much time they have before needing the money -- and their short-term liquidity needs -- what part of that money they can't afford to have invested in volatile assets -- shape asset allocation, without their combination automatically determining a single correct allocation: two investors with similar data on these three factors can reasonably arrive at different allocations.

\n

Example

\n

A young investor with a long horizon and no immediate liquidity needs can allocate a larger proportion to stocks than another investor close to needing part of that capital, even if both share the same risk profile -- the second should keep a liquid, conservative portion to cover that near-term need, regardless of their psychological tolerance for volatility.

\n

Common mistakes

Summary

\n

Time horizon influences how much room there is to take on volatile assets before needing the money, and short-term liquidity needs require keeping a portion of the portfolio in liquid, low-risk assets, regardless of the overall horizon. Together with risk profile, both factors shape the right asset allocation for each investor, without automatically defining it.

\n

This level's five previous modules introduced, one by one, the criteria that make up a coherent portfolio: asset allocation based on risk profile and time horizon, diversification, managing concentration risk and correlation, rebalancing, and investor taxation. This lesson doesn't add any new criterion -- it brings together the ones already covered into a practical sequence.

\n

The starting point is always the same: asset allocation, already covered in Module 1, decided from the investor's risk profile and time horizon. That allocation sets, in general terms, what proportion of the portfolio would correspond to each asset class -- stocks, bonds, ETFs, investment funds, commodities, or currencies, all already covered in Level 1 -- before choosing any specific instrument.

\n

Once the allocation is set, the next step is diversifying within each asset class and across them, already covered in Module 2: combining assets that don't all behave the same way reduces the portfolio's risk without proportionally reducing expected return. Diversifying isn't simply adding up different instruments -- it's watching, as Module 3 showed, that no position concentrates a disproportionate risk, taking into account how the chosen positions relate to each other.

\n

Sizing each position, also covered in Module 3, is what translates the allocation and diversification into concrete numbers: how much weight each position gets within the portfolio, consistent with its contribution to overall risk, not just with the investor's conviction in that specific idea.

\n

Finally, building a portfolio doesn't end at the moment of purchase. The tax cost of trades -- already covered in Module 5 -- and the future need to rebalance -- already covered in Module 4 -- are part of the criteria from the start, not an afterthought: a well-built portfolio anticipates that it will need to be reviewed over time, a topic the next lesson develops.

\n

Example

\n

An investor with a long time horizon and a risk profile that tolerates swings decides, based on their asset allocation, to put most of the portfolio into stocks and a smaller part into bonds. Within the stock portion, they diversify across several companies and sectors instead of concentrating the investment in just one; within the bond portion, they do the same across several issuers. Position weights have been set accounting for their contribution to concentration risk and how they relate to the rest of the positions.

Summary

Building a real portfolio means applying, in sequence, the criteria already covered in this level: asset allocation based on risk profile and time horizon, diversification within and across asset classes, sizing each position based on its contribution to overall risk, and anticipating the tax cost and the future need to rebalance.
