Notes on option-based investing, risk management, and tax-smart strategy.
How a Covered-Call Overlay Works on a Concentrated Position
A covered-call overlay sells calls against shares an investor already holds, turning a concentrated position into a source of premium income while the investor plans a paced, tax-aware exit.
Read paper →Covered-Call Overlay vs. Just Selling the Stock
Selling a concentrated position outright is simple and final, but it crystallizes the full tax bill at once. A covered-call overlay is a slower, more involved path that lets an investor exit on a schedule. The right choice depends on the goal, not on which is “better.”
Read paper →How Option Overlays Generate Monthly Income
Option overlays produce income by selling options and collecting premium on a recurring schedule. The mechanism is straightforward, but the income is variable, the upside is capped, and the strategy carries real risk — not a fixed yield.
Read paper →What a Defined-Outcome Option Strategy Costs
A defined-outcome strategy sets a known floor and a known ceiling on returns over a period. The “cost” is rarely an upfront fee — it is mostly the upside given up to pay for the downside protection. Understanding that trade is the key to using one well.

If years of vested RSUs have left most of your net worth in one tech stock, you have more choices than “hold and hope” or “sell and pay the tax.” Here is how to think through them.

The lockup just lifted and your shares are finally sellable. Before you sell everything — or nothing — here is how to think about timing, tax, and protecting the value you have on paper.

Inheriting a large single-stock position usually comes with a step-up in basis that resets the tax math entirely. That one rule changes what the smart move is.

A stock you bought long ago may now be most of your portfolio with a basis near zero. Selling means a large tax bill, but holding concentrates your risk. Here are the realistic paths.
Read paper →Exchange Fund vs. Option Overlay
Two ways to address a concentrated position without an immediate sale: contribute shares to an exchange fund for pooled diversification, or hold the stock and manage risk with an option overlay. They differ on control, liquidity, and timeline.
Read paper →Covered Calls vs. Protective Puts
A covered call sells upside for income; a protective put pays for downside insurance. They sit on opposite sides of the same position — one generates premium, the other costs it — and many investors combine them into a collar.
Read paper →Direct Indexing vs. Option Overlay for Diversification
Direct indexing builds a diversified portfolio around your concentrated stock and harvests losses to offset the gains from trimming it. An option overlay reshapes the position’s risk in place. They work on different parts of the same problem and can be used together.
Read paper →QSBS vs. Other Concentrated-Stock Strategies
Qualified small business stock can exclude a portion — potentially all — of gain from federal tax under IRC §1202, but only if strict eligibility tests are met. For shares that do not qualify, exchange funds, overlays, and other tools manage the gain rather than exclude it.
Read paper →RSUs and Post-IPO Wealth: Managing Single-Stock Concentration
Vested RSUs and post-IPO shares often leave employees with most of their net worth in one stock — and a large embedded gain. Here is how to think about diversifying without an all-at-once tax hit.

A California investor with $10M in long-term gains faces roughly $3.7M in tax. An actively managed option overlay offers a fourth path: begin the exit on your own terms, with defined floors and ceilings, while premium income partially self-funds the eventual tax.

An RIA can add option-overlay capability for concentrated-stock clients through a sub-advisory relationship, avoiding the trading desk, options approvals, and tax-lot tooling an in-house build would require.
Read paper →Outsourcing Options Management vs. Doing It In-House
A side-by-side look at what running option overlays in-house costs an RIA versus delegating the mandate to a sub-advisor — in fixed cost, key-person risk, compliance surface, and capacity.

How an RIA can slot a defined-outcome sleeve into an existing model-portfolio framework — where it fits in the allocation, how it reports, and what to watch operationally.

Five common solutions for a concentrated position — option overlay, §351 ETF conversion, exchange fund, long/short extension, and prepaid forward — compared across exposure, liquidity, timeline, basis, fees, control, and tax treatment.

The fourth quarter is when a concentrated position’s tax picture comes into focus — gains, losses, and holding periods can all be managed before December 31, if you start early enough.
Read paper →Tax-Loss Harvesting With Option Overlays
Harvesting losses near year-end can offset realized gains — but the wash-sale rule and the straddle rules both bear on how options interact with the harvest, so the sequencing matters.
Read paper →What to Do Before December 31 With Appreciated Stock
An appreciated position carries a set of year-end choices — realize, hold, hedge, or begin a paced exit — and the settlement and holding-period mechanics decide which ones still count for the current tax year.
Read paper →Constructive Sale Rules (IRC §1259): What Triggers Them and How to Avoid Them
IRC §1259 can treat a fully hedged appreciated position as if it were sold — accelerating the gain you were trying to defer. Knowing what trips the rule is essential to designing a tax-smart overlay.
Read paper →Qualified Covered Calls and IRC §1092: Tax Treatment Explained
The qualified covered call (QCC) exception to the straddle rules lets an investor recognize income from writing a call even when the loss on the underlying shares is not yet realized — a key mechanism behind tax-smart option overlays.
Read paper →How to Sell Concentrated Stock Without a Huge Tax Bill
A large single-stock position with a low basis can carry a seven-figure tax bill on sale. An actively managed option overlay lets you begin diversifying on your own terms — with defined floors and ceilings — while premium income partially self-funds the tax.

A collar combines a covered call and a protective put to define a range — a floor below and a ceiling above the current price — within which an investor holds a position while executing an exit plan.
Read paper →The Best Edge We Found, and How It Died
Gross profitability was the most credible factor in the study — positive in every regime, t=1.69, theory-backed. Against the cap-weighted index it was already worth only ~+0.6%/yr, and survivorship bias of ~+3%/yr likely exceeded it. Even our best factor was marginal and fading. What survived was not a return forecast at all.

Test eight patterns on a stock and the best one will look great by luck. The Deflated Sharpe Ratio corrects a track record for how hard you searched — and in our single-name tests it rejected six of eight names that had raw Sharpe ratios above 0.7.
Read paper →You Can’t Backtest a Number That Gets Rewritten
Estimate-revision and ranking feeds restate their own history as new data arrives. Backtesting today’s snapshot against old prices is pure look-ahead — you are testing knowledge you could not have had. The only honest fix is to archive the live signal forward.
Read paper →A 26% Bug: When ROE Is Nonsense
A “quality” signal based on return-on-equity looked positive (IC +0.013) — until we found it was manufactured by negative-equity outliers. About 26% of the S&P 500 has negative book equity, which makes ROE meaningless. A plausible information coefficient is often a bug, not a finding.
Read paper →Good Rank, No Money: The IC-to-P&L Gap
A signal can rank stocks correctly and still make no money. Our highest-information-coefficient composite (IC +0.037) produced a long/short Sharpe of just +0.24 — and a naive mean-variance optimizer made things worse, not better. Ranking well is not the same as trading well.
Read paper →The Alpha Lives Where the Costs Are
Three independent signals — short-term reversal (t=2.35), small-cap post-earnings drift (+2.7%/yr gross), and pairs stat-arb — all showed the same signature: a real gross edge, concentrated precisely in the illiquid, hard-to-borrow names, killed by the exact costs that let it persist. Limits-to-arbitrage is a law, not an excuse.
Read paper →Your Edge vs. the Index You Can Actually Buy
Gross profitability beat an equal-weight basket by +2.7%/yr. Against the cap-weighted index a client can actually hold in an ETF, that shrank to about +0.6%/yr — and turned negative at higher tilt. Pick the wrong benchmark and you invent alpha that was never there.
Read paper →The Dead Companies Aren’t in Your Backtest
Most free data sources can’t price delisted stocks, so backtests silently drop the losers and flatter every result. In our universe work, roughly 36% of true historical index members were unpriced — and a no-tilt basket appeared to beat the market by +3.2%/yr from survivorship alone.
Read paper →Walk-Forward, or You’re Lying to Yourself
The difference between a backtest you can trust and one you can’t comes down to a handful of mechanics: measure returns not levels, expand the window forward in time, normalize within each date, key fundamentals to filing date, and decompose every apparent edge before believing it.

An option-skew signal looked like the single strongest predictor in our study — IC +0.0142, t=1.42, Sharpe +0.45 — on a 120-stock universe. Run on the full S&P 500, it collapsed to t=0.00, and went negative in the COVID period. The subset mirage is how a great-looking signal turns out to be noise.
Read paper →The R²=0.997 Lie: The Most Common Backtest Self-Deception
A neural network can “predict” tomorrow’s stock price with 99.7% accuracy and be completely worthless — because it is just echoing today’s price. This is the trap that fools more backtests than any other, and it is the reason our entire research program changed what it measured.
