Financial advisors often view a large cash position (e.g., 20%) as a drag on performance. Jared Dillian reframes this, arguing that cash is not a dead asset but a valuable call option. It provides liquidity to seize opportunities, like buying real estate or other assets when they become cheap, while also dampening portfolio volatility.

Investors often start new positions too small due to myopic loss aversion. A powerful nudge is to set a default entry size for all new ideas. While deviations are allowed, requiring a manager to explicitly document their reasoning for going smaller introduces "process sludge" that forces more rational thinking.

Instead of making large initial bets, a more effective strategy is to take small, "junior varsity" positions. Investors then aggressively ramp up their size only when the thesis begins to demonstrably play out, a method described as "high conviction, inflection investing."

Many investors wrongly equate high conviction with making a large initial investment. A more evolved approach is to start with smaller at-cost positions, allowing a company's performance to earn its eventual large weighting in the portfolio. This mitigates risk and improves decision-making.

A core discipline from top hedge funds is to re-evaluate every holding daily, regardless of past performance. This forces an objective assessment of whether you would buy the position today, removing emotional attachment and the sunk-cost fallacy from decision-making.

Instead of constant activity, experienced traders understand that cash is a strategic position. They exercise patience, sidestepping low-conviction periods to wait for ideal conditions. The majority of their returns are made in short bursts where they can deploy capital aggressively into high-conviction setups.

By seeding new positions at ~0.5% and rarely exceeding 1% at cost, the fund mitigates the behavioral risk of averaging down too aggressively into a failing investment. This disciplined approach prevents a small mistake from becoming a large portfolio loss.

To combat the emotional burden of binary sell-or-hold decisions, use the "Go Havsies" method. Instead of selling a full position, sell half. This simple algorithm diversifies potential outcomes—you benefit if it rises and are protected if it falls—which significantly reduces the psychological pain of regret from making the "wrong" choice.

A powerful risk management technique is setting a maximum percentage of your portfolio that can be invested in a single stock *at cost*. A 5% at-cost limit means once you've invested 5% of your capital, you cannot add more, even if the stock price plummets and its market value shrinks. This prevents chasing losers.
