Diversification said "don't bet on one thing." Allocation says "here's the recipe — what % goes where." Allocation accounts for ~90% of long-term portfolio outcome. Stock-picking accounts for far less than people think.
STEP 1
The Big Decision: Stocks vs Bonds vs Cash
The single most important number in your portfolio is your stock-bond mix.
Stocks = growth engine. Bumpy ride, big returns over 20+ years.
Bonds = ballast. Lower returns, but they cushion crashes.
Cash/HISA = tactical buffer. Emergency fund + active-trading dry powder.
Common rules of thumb for the stock %:
Rule
Says
For age 25
"110 minus age"
110 - age = % in stocks
85% stocks / 15% bonds
"120 minus age"
aggressive version
95% stocks / 5% bonds
"Risk-tolerance based"
match your stomach
80–100% stocks if you can stomach –30% drops
⚠️ Real talk
These rules are approximations. The honest answer at 25 is: anywhere from 80% to 100% stocks is defensible. The variance comes from how you'd react to a 40% market drop. If you'd panic-sell — keep some bonds. If you'd shrug and keep buying — go 100% stocks.
STEP 2
Within Stocks — The Geographic Split
Once you've decided X% in stocks, you split that across:
Region
Typical allocation
Example ETFs (Canadian)
🇨🇦 Canada
20–30%
VCN, XIC
🇺🇸 US
40–50%
VFV, XUS, VUN, XUU
🌏 International (developed: Europe, Japan, Australia)
15–25%
XEF, VIU
📈 Emerging markets (China, India, Brazil)
5–10%
XEC, VEE
OR — and this is what 90% of people should actually do — buy a single all-in-one ETF (VEQT, XEQT) that already does this split internally and rebalances itself.
STEP 3
The Two-Bucket Mental Model
You said you want some active trading on the side. Here's the cleanest way to think about it:
🛡️ Long-Term Bucket (90–95%)
Set-and-forget
1–3 ETFs total
Auto-deposit each paycheck
Don't check it more than monthly
Rebalance once a year (or buy an all-in-one and skip rebalancing)
This is your retirement
🎯 Active Bucket (5–10%)
Individual stocks (MBI, ASTI, picks)
You can lose all of it without changing your retirement
Track every trade
Position sizing rules (Module 5)
Treat it as serious play, not casino play
This is your sandbox
🎚️ Try the slider
Open the Strategy Slider after this lesson. Move the slider from 100% long-term down to 70/30 and watch how the projected outcomes change at different return assumptions.
STEP 4
Why the Active Bucket Has a Cap
Honest stat: most active investors underperform a simple index ETF. SPIVA reports show ~85–90% of professional fund managers underperform the S&P 500 over 10+ years. Amateurs do worse on average.
If pros with Bloomberg terminals and PhDs in finance can't beat the index reliably, the realistic expectation for your active bucket is: you'll underperform the long-term bucket on average. That's fine — you're trading some expected return for the fun and learning. But it's why the cap matters.
The long-term bucket is your wedding meal. The active bucket is dessert. You don't replace dinner with cake. You eat the cake at the end and enjoy it — but the meal already nourished you.
STEP 5
Concrete Recipe — A Defensible Default for You
If you want a starting point you can implement this month, here's one (you'll refine in Module 5):
📋 Default 25-year-old Canadian Portfolio
3–6 months expenses in HISA (Wealthsimple Cash, EQ Bank) — emergency fund, separate from investing
Long-Term Bucket (90% of investing $):
One ETF: VEQT or XEQT — done
Or: 30% VCN + 50% VFV + 20% XEF (manual mix)
Active Bucket (10% of investing $):
Individual stocks you've researched
Position sizing: max 2% of total portfolio per single stock
🧠 Quick Check
You're 25, can stomach a 30% drop without panic-selling, and want some active trading. What's a defensible split?
100% individual stocks I research carefully
85–95% diversified equity ETFs (long-term) + 5–10% individual stocks (active bucket) + emergency fund in HISA
