Track C — Core

55% of capital, compounding quietly

Track C is the largest and slowest part of the system — the compounding core that the catalyst sleeves (B, B-2) and the income sleeves (A, A-2) orbit. Its job is not to be clever. Its job is to own the market broadly, cheaply, and tax-efficiently, and to keep owning it through every drawdown the other tracks react to. The edge here is time and temperament, not timing.

Where Track B asks "what reprices this, and by when," Track C asks nothing of the day at all. It buys broad index exposure on a schedule, lets dividends and earnings compound, and is deliberately the most boring track you run. Two refinements make it more than a plain index: a systematic value tilt (Track C-2), and a VIX-triggered capitulation override that accelerates buying precisely when fear is greatest.

Broad, cheap, tax-placed

The anchor is broad-market beta — total US market (VTI) plus ex-US for global ownership. The discipline is in the boring parts: low cost, low turnover, and putting each holding where it's taxed least.

Buy hardest when fear peaks

The one moment Track C abandons its calm is a volatility spike. A VIX-triggered capitulation override accelerates core buying in staged steps as fear deepens — turning the market's panic into your accumulation. This is the core's only timing rule, and it points the opposite way to instinct.

The value tilt — factor, not selection

Value investing's first honest home in this system: a systematic value-and-quality tilt inside the core. No stock-picking, no judgment, no daily scan — a target allocation that leans toward value, rebalanced by drift bands quarterly. It harvests the documented value premium the way the rest of your machine works: rules held through discomfort, not discretion.

The tilt is a partial lean over broad-market beta, not a bet against it — you keep the anchor and add value and quality factor exposure alongside. Quality is deliberate: value-trap insurance at the index level, screening out the cheap-because-dying names a naive value screen would buy. Rebalancing is by bands — drift must breach both a relative threshold (>5%) and an absolute one (>3pp) — not the calendar alone, to limit turnover and tax drag, which matters because the core lives largely in taxable. International value is flagged for taxable specifically, for the same FTC reason as the broad ex-US holding.

def check_rebalance(holdings, targets, rel_band=0.05, abs_band=0.03):
    total = sum(h.market_value for h in holdings)
    for sleeve, tgt in targets.items():
        cur = by_sleeve.get(sleeve, 0) / total
        drift_abs = cur - tgt                 # percentage points off
        drift_rel = drift_abs / tgt           # relative to target

        # Trade ONLY if BOTH bands are breached — avoids churning
        # small sleeves on tiny relative moves (turnover = tax drag):
        if abs(drift_rel) > rel_band and abs(drift_abs) > abs_band:
            action, delta = ("BUY" if tgt*total > mv else "SELL"), tgt*total - mv
        else:
            action, delta = "HOLD", 0

# No conviction, no entry signal, no exit. The strategy IS the target
# weights; the discipline is holding the tilt when it underperforms.
# Prefer new-contribution rebalancing; sell last, and tax-aware.

Run on demand each quarter: python3 trackc2_tilt.py prints the drift table and the trades, if any. It is not a scanner and has no daily cadence — checking it more often than quarterly only tempts you to tinker.

The thematic sleeve — own the trend, don't trade it

An optional, hard-capped sleeve inside the core for high-conviction secular themes — physical AI and robotics, the energy build-out behind compute, AI infrastructure. These names fail every value screen by construction, which is exactly why they cannot live in A-2. C-3 is a growth judgment expressed on C's temperament: bought slowly, held for a decade, and sized so that being entirely wrong is recoverable.

What the core is for

Track C is the gravity the rest of the system orbits. It's why the alpha sleeves can afford to be aggressive and the income sleeves can afford to be patient: the bulk of your compounding is happening here, mechanically, regardless of what B, B-2, A, or A-2 do this week.

Keep the capital lines separate. The override reserve is part of C's allocation, pre-designated — never funded by selling A or B in a panic, which is exactly when those sleeves are worst to liquidate. The whole architecture only works if each track's risk and cash stay in their own lane.
