TIP846: Stock Picker: How to Live Off Your Portfolio w/ Ian Cassel

Ian Cassel defines living off a portfolio as covering expenses while continuing to grow capital faster than the S&P 500—not spending all investment gains. He went full-time as a private micro-cap investor by 2018, after choosing a $2 million portfolio target that he believed could withstand a 50% decline without forcing him to change strategy. The target was about surviving a severe drawdown, not forecasting five years of returns.

When he began, Cassel was single and could live on $2,000 a month. He prioritized independence and low fixed costs, while recognizing that private investors do not get an employer 401(k) match, employer-paid health care, or a safety net. He now keeps two years of personal expenses in cash so he can avoid selling stocks at a bad time. His wife took a couple of years to adjust to the volatile finances, and their arrangement—his income covering fixed costs and her income covering variable costs—allowed spending to flex.

The central risk is needing portfolio withdrawals during a downturn. Cassel said an investor who sells to cover expenses after a 25% decline may be more exposed if another 25% decline follows. Long-term investors with six-, 12-, or 24-month holding periods can face a year or two of falling or stagnant stocks, creating both financial and emotional strain. Cassel describes his returns as “consistently inconsistent”: he might lose a few hundred thousand dollars one year, break even the next, and make $1 million the year after. Short-term traders may find full-time investing easier because gains from trades held for days or weeks can feel more like paychecks.

Cassel’s own start was unusually favorable, though he does not treat it as proof of skill. At 16, he invested $5,000 of the $20,000 his parents had saved for his education in a technology stock, which doubled in two months. He says the $20,000 grew to $120,000 between around 1996–97 and the 2001 dot-com peak through luck and a bull market; the portfolio later lost 90%. The early gains gave him confidence to try to recover and may have raised his risk tolerance. Going full-time after the Global Financial Crisis also helped him see that he could endure a 50% drawdown.

His micro-cap approach depends on turnover and realistic expectations about how long growth can last. Small companies can hinge on a key person, customer, geography, or end market, making them more fragile than large caps. A winner’s high-growth period may last only six to 24 months, or as long as 36 months; after a major customer win, for example, several quarters of 30% growth can make later comparisons harder. Cassel says most micro-caps must be sold within 36 months, even if they have done well, while only a few exceptional businesses compound for five or 10 years or longer. He cautions against automatically applying a buy-and-hold or “coffee can” strategy to micro-caps, while noting that larger, more robust companies may suit that approach.

Cassel keeps a target of 3%–5% cash to start positions and add during drawdowns, rather than holding 20% or more when he could invest in his best ideas. If he wants to buy beyond available cash, he sells the holding he has least conviction in. He also tests his decisions by asking how he would position if his portfolio were up 30% year to date rather than down 10%. As his fund grew, he moved from roughly 10 holdings to 15 or 16 and shifted from 10%–15% positions toward 3%–5% positions, believing more holdings create more chances to win. A micro-cap that doubles, triples, or quadruples can become a major position even if it starts small.

The fund remains capacity-constrained: it is about $40 million, invests in companies with market capitalizations around $20 million, and focuses on micro-caps below $100 million within a broader range extending to $500 million. Cassel can imagine growing it to $100 million, but not to a billion, because illiquid small-company investments limit how much capital can be deployed. He is the fund’s largest investor and favors a broad, stable investor base over dependence on a few large investors, whose withdrawals could force damaging sales. He benchmarks against the S&P 500, which he calls a formidable, low-cost competitor, and believes his portfolio can outperform it over the long term.
