How to Build a Modern Portfolio When Rates Are High: The 30-30-40 and Selective Timing

There is no single perfect formula for building a modern portfolio. That is the clearest line in the video: no magic ratio works in every regime, and staying fully passive is not the only honest choice. The speaker defends selective timing while still believing in positive drift. In other words, markets tend to grind higher over time, but that does not force you to apply the same formula at every price. Modern Portfolio Theory, introduced by Harry Markowitz in the 1950s, framed diversification as the only free lunch. After 2022, when stocks and bonds fell together on rapid rate hikes, confidence in that neat separation cracked. The debate today is the same fault line: is it more rational to stay invested through everything, or to ease off when prices look stretched?

That worldview maps directly to the current mix the speaker uses: 30-30-40. Thirty percent for active trading, thirty percent for long-term holdings, and forty percent in cash and treasury equivalents. For his own history that cash slice is unusually large, and there are deliberately no long-term bonds and only a limited long-term equity book. The reason is simple: when rates are high, cash stops being a zero-yield parking lot. In mid-2026 the three-month Treasury bill yields around 3.70 percent and money-market funds sit nearby; in the zero-rate era that same cash yielded about 0.5 percent. Cash now pays like an insurance policy that also earns. He notes that if rates were at 2 percent his cash would be near zero. Think of it like a thermostat and a blanket: when the heat from yield drops, you need less blanket.

Selective timing shows up in how he treats public versus private markets. At all-time highs he prefers not to chase broad index funds and would rather wait for lower levels. Instead he is leaning more aggressively into private companies than public ones, because public prices have already discounted a lot of optimism. The trade-off is clear. Private exposure can capture growth before it is priced and often comes with an illiquidity discount. The cost is illiquidity itself, opaque marks, and an exit that can take years. It is a deliberate lane change while most of the crowd stays in the same lane. He adds that if rates keep climbing he would push even more toward cash; the 30-30-40 slider is not frozen, it moves with the level of rates and prices.

How the trading sleeve is made capital-efficient

For the trading sleeve he recommends only capital-efficient, liquid tools: options, futures, and futures options. The allocation is not by gut but by buying power and adjusted notional. The mechanics can be put in three steps: 1) measure the buying power your account actually uses, 2) shrink notional by about 30 percent when the instrument is a future or future option, 3) apply the same haircut again if you are on portfolio margin. Why the haircut? Futures and portfolio margin embed leverage; keeping the same nominal quietly inflates risk. On the options side, spreads are more capital-efficient than outright short options, while long options carry a higher probability of profit on some structures but a different premium and decay profile. Cboe and Schwab documentation on portfolio margin explains the same idea: unlike Reg T, which margins each strategy in isolation, portfolio margin looks at the net risk of the whole book. Done right it brings retail leverage closer to institutional terms; done wrong a small shock triggers a margin call.

The boldest claim is that all of this will become trivial with AI — normalized with half a token, in his words. The background matters: today a retail investor learns futures, options, and margin as if they were separate languages. Tomorrow a single agent could translate buying power, adjusted notional, and cross-product correlation into one slider. Imagine a maps app collapsing three different routes into one clear path. The practical implication cuts both ways. Technology will lower the barrier to building the structure, but it does not lower the barrier to risk. Making leverage one click easier also makes losses one click larger.

Passive sleeve: anything goes, but his choice is listed markets

The passive sleeve, in his words, can be anything you will actually leave alone — real estate, even Pokemon cards. The card anecdote is not just banter, it is the philosophy: a passive position is one you do not touch for years. His own preference is the listed marketplace: mostly stocks, with some commodities and some digital assets. The passive commodity examples he gives are currencies — the British pound and the Japanese yen — held without trading. Why count FX as passive? Its correlation to stocks and bonds is low, carry can be modest, and it adds a different return driver. Like adding lemon instead of salt, it balances the same dish differently. A critical note: a Pokemon card is an illiquid collectible whose price depends on fashion and depth of the buyer pool; it cannot be turned into cash like a stock. The point is not that everyone should hold the same passive mix, but that you should hold what you can leave untouched and still sleep at night.

The beam holding all of this together in a high-rate regime is cash itself. Morningstar noted in 2026 that cash diversified portfolios better than bonds in the recent stretch, and the iShares 60/40 benchmark wobbled again on September 23 when yields surged. After 2022, when long bonds fell with equities, many investors rediscovered the Treasury-bill ladder: stagger 4-, 8-, 13-, and 26-week bills, roll each rung as it matures, keep quarterly liquidity and a state-tax exemption, and let the ladder reprice gradually if rates fall. The CNBC coverage of that September rate jump is a reminder why long duration is unwanted in the passive book right now: when yields spike, prices drop and duration risk shows up. When does the mix rotate back? When the curve normalizes, real yields ease, and equity valuations digest, that 40-point cash block can slowly migrate back into duration. Until then cash is not a parking lot but a position that behaves like an option premium.
