Lynn’s Field Strategies

Risk disclosure: The main text of this book strictly follows the disciplined allocations at the core of CLEC (433 / 442 / 703 and so on). This appendix, by contrast, compiles the advanced variant strategies shared by Lynn, a student of Teacher James (a regular contributor, currently based in Singapore), in the community and on public programs, some of which Teacher James has discussed in his videos. They do not belong to the CLEC core allocation, nor do they represent Teacher James’s general advice to all readers; they are not suitable for beginners and are recorded merely as tools, not listed as recommended allocations in the main text. The content is all an instructional compilation of publicly available historical backtests, and does not constitute individual investment advice or specific instructions on when to buy or sell.

Smart Rebalancing That Does Not Deplete the Cash Cushion (QQQ to QLD)

CLEC’s smart rebalancing usually deploys the cash position to add on dips during down years. Lynn proposes a variant that “does not deplete the cash cushion”: instead of touching the precious cash defensive position, you swap the underlying (1×) QQQ you already hold directly into the 2× leveraged QLD, thereby raising the overall Beta during a down year to greet the future rebound, while keeping the cash level fully intact.

• Spirit: When you want to raise exposure during a down year, use “underlying to leveraged (QQQ to QLD)” instead of “spending cash to buy stock,” and do not touch a single cent of the cash cushion.
• Reversal: When the market rebounds and the overall Beta returns to the target level or makes a new high, swap QLD back into QQQ and bring Beta down to the original allocation.
• Positioning: This is still an advanced variant of smart rebalancing; it simply changes the “fuel for rebalancing” from cash to the underlying position itself.

Caution: This method still deviates from the main text’s literal discipline that “the underlying fund is absolutely never touched” — in practice it means selling QQQ and buying QLD, only without touching cash; it requires precise Beta calculation and strict adherence to a leverage ceiling that does not exceed the original allocation. QLD is 2× leveraged, and under historical synthetic stress tests, a large-scale bear market could still produce a drawdown approaching -80%, which you must be able to withstand. If the swap is executed in a US taxable account it will trigger capital gains tax, so it is more suitable for tax environments free of capital gains tax such as Taiwan or Singapore. Beginners are strictly forbidden to apply it. (Video 00545)

If the allocation goes through years of large gains and the leveraged portion naturally swells in proportion, pushing the whole account’s effective Beta up to 1.4, the handling principle is to first check whether the cash cushion has already reached its full level (Lynn personally holds 15 to 20 years of living expenses) — if the cash is already sufficient, there is no need to keep hoarding the QLD gains into cash (to avoid a cash drag); instead, during an up year, shift the extra QLD gains into buying the QQQ underlying, which both cools down Beta and keeps the funds compounding in the market. If Beta rises so high that you cannot sleep, or if the cash has not yet reached its target, then simply sell QLD to cut leverage and bring Beta back down to 1.0 / 0.8.

The Low Borrowing-Ratio Risk-Control Practice of USD Pledging at a Foreign Bank

Lynn (a regular contributor, currently based in Singapore) borrows against USD collateral at Citibank, and strictly keeps the actual borrowing ratio within a safety margin “far below the approved limit” (for example, approved for 50% but drawing down only 15%), thereby compressing the margin-call forced-liquidation risk to an extremely low level — but this is a “substantial reduction,” not an “outright elimination”: the bank may still adjust collateral haircuts, ratios, and concentration limits, and an extreme decline could still approach a margin call. This 50% / 15% is a single case, not a universal standard for all banks and instruments. This operation demonstrates the spirit of pledging in practice: the approved limit is merely “the ceiling the bank is willing to lend,” while true peace of mind comes from “deciding for yourself how much to borrow.” For investors who have already opened a foreign-bank USD pledging account and are preparing to enter the “Buy, Borrow, Die” stage, this practical case can serve as a reference benchmark for setting the upper limit on their own borrowing ratio.

The Time-Value Arbitrage Mechanism of BOXX (Terminology Supplement)

The CLEC system lists BOXX alongside 00865B and SGOV as cash-like defensive tools, but the reason BOXX can achieve “no distributions, automatic net-asset appreciation” hides an extremely ingenious piece of financial engineering behind it — “options time-value arbitrage (Box Spread).”

Actually, when you say it has nothing to do with interest rates, in fact it is all about earning that time value, arbitraging time value, and that time value is really the risk-free rate, the short-term risk rate, which is essentially close to the central bank rate. Because you have to understand that within an option there is something called time value, and time value should equal what? It should equal the risk-free rate, so BOXX is arbitraging that risk-free rate. (Video 00506)

A simple breakdown: BOXX simultaneously builds four “call + put” spread combinations on the S&P 500 index (commonly called a Box Spread), so that the terminal value of the entire combination must equal a fixed amount at expiration. The difference between the cost paid when buying the combination and the fixed amount recovered at expiration is the time value corresponding to the “risk-free rate” over that period. BOXX continuously rolls this combination, which amounts to obtaining, each day through the options market, an economic return close to the short-term risk-free rate (roughly equal to the central bank rate); but this is not zero-risk magic, and it still bears risks such as fund fees, liquidity, trade execution, tax classification, and regulatory interpretation.

This design brings two key advantages:

• It internalizes interest into net asset value and does not distribute dividends — this can reduce the tax friction caused by the annual distributions of traditional short-bond tools, but BOXX is not a tax-free tool, nor does it guarantee that a taxable distribution will never occur (there has been a record of taxable distributions being made); whether it suits US tax residents, and how the annual fund tax classification works, still depends on account type and CPA opinion.
• Its return is close to the central bank rate — in the high-rate environment of 2025 to 2026, BOXX’s annualized return is about 4.81%, roughly on par with SGOV and short-term Treasury ETFs, the difference being that it lacks the tax friction of annual distributions (which is not the same as tax-free).

If CLEC’s cash-like position (the 30% / 20% in the 433 / 442 allocations) is held by a US investor, BOXX is a common choice. Taiwan tax residents should note: BOXX is still an overseas ETF, and buying it involves overseas income, sub-brokerage / overseas brokers, exchange rates, US estate tax, cross-border inheritance, and other issues, so you cannot treat it as comprehensively superior to domestic tools just because it “saves distribution tax.” Those who do not want to deal with cross-border complexity may prioritize studying Taiwan-listed short-bond products such as 00865B.
