๐Ÿ“‰ Trends, Patterns & Why Prediction Is Hard

โฑ ~25 min๐Ÿง  Theoryโš ๏ธ Reality check

You wanted to learn about predicting trends. Here's the honest version: short-term price prediction is essentially impossible, and most people who claim otherwise are either lucky or selling something. But there are real, useful patterns at the macro level. Let's separate signal from noise.

STEP 1

The Three Time Horizons of Prediction

HorizonPredictabilityWhy
Tomorrow~50/50 (random)News, sentiment, fund flows dominate
Next monthSlightly above randomSome momentum effect, but unreliable
Next yearMaybe 55โ€“60%Trends do persist somewhat
Next 10 years~85% confident in directionEconomic growth + reinvested earnings
Next 30 years~99% confident global stocks riseProductivity + population + innovation

Notice the pattern: predictability increases with time horizon. Daily moves are noise; multi-decade moves are signal. This is why long-term investing works and day trading mostly doesn't.

STEP 2

The Common "Patterns" People Trade

You'll hear about these โ€” head-and-shoulders, double tops, cup-and-handle, golden cross, MACD crossovers, RSI overbought, etc. This is technical analysis.

โš ๏ธ Honest assessment Technical analysis works just well enough to keep practitioners hooked. Most rigorous studies find tiny edges, often eaten by trading costs. The patterns that work are usually self-fulfilling โ€” enough traders watch the same patterns that they sometimes act in coordination. But there's no reliable money machine here. If there were, it would be arbitraged away in seconds by hedge funds with $10B and PhDs.

You can learn it for fun, but don't bet your retirement on it. Learn it the way you'd learn poker odds โ€” useful at the margin, not a paycheck.

STEP 3

The Real "Intrinsic Variables" That Drive Returns

You asked about intrinsic features that affect ROI. Over the long term, here's what actually matters:

DriverHow it affects returns
Earnings growthCompanies that grow profits โ†’ stock price grows. ~50% of long-term return.
Dividends + reinvestmentCompounding cash payouts. ~40% of long-term S&P 500 total return historically.
Valuation expansion/contractionP/E going from 15 to 25 (or vice versa). Volatile, mostly evens out.
InflationErodes nominal returns. Why "real" return = nominal โˆ’ inflation.
Interest ratesHigher rates = bonds compete with stocks, can pressure valuations down.
CurrencyUSD/CAD swings can add/subtract 5โ€“10% in a year for non-hedged holdings.

Long-term investors don't need to predict any of these precisely. They just need to be invested in the broad market so all the positive drivers compound for them over decades.

STEP 4

Three Reliable Macro Patterns

These are macro-level statistical regularities that have held over multiple decades and many markets:

  1. Mean reversion at the index level. When the S&P 500 has a terrible decade, the next decade is usually above average (and vice versa). Doesn't help time markets but helps stay calm in crashes.
  2. Recessions happen ~every 7โ€“10 years, last 6โ€“18 months, and the market always recovers within a few years. Crashes are routine, not exceptional.
  3. Time in market beats timing the market. Studies repeatedly show that missing the 10 best days of any decade roughly halves your returns. Since the best days often follow the worst days, sitting out crashes destroys returns.
Trying to time the market is like trying to leave a concert at the exact moment it peaks. By the time you realize it was peaking, the moment is gone. Better to stay through the whole show โ€” including the boring parts.
STEP 5

What You Should Actually Do With Trend Knowledge

Knowing trends are mostly unpredictable should change your behavior in three ways:

  1. Don't try to time entries. Just buy regularly (DCA, next module).
  2. Don't sell when the news is scary. "Sell because recession" is a strategy that loses to "hold and keep buying" almost every time.
  3. For active bucket: focus on the business, not the chart pattern. Pick companies you understand; ignore the squiggles.

๐Ÿง  Quick Check

Headlines say "recession likely in 6 months." Your TFSA is in XEQT. What should you do?
Sell to cash, wait for the crash, buy back at the bottom
Keep buying on schedule. If a crash hits, you'll be buying at lower prices. Don't try to time it.
Switch entirely to bonds
Buy individual gold mining stocks
