Position sizing

Position sizing is a portfolio discipline, not a feeling

Position sizing is where conviction meets portfolio reality. SoloTerminal helps self-directed investors compare target weight, concentration, factor overlap, and catalyst risk before adding to a U.S. stock position.

Size before emotion scales the trade

When a position is working, investors often add first and rationalize later. A sizing workflow flips that order: define the intended weight, the condition for adding, and the condition for stopping before the next decision point.

Check hidden concentration

Two different tickers can still be the same bet through factor overlap, sector concentration, or macro sensitivity. Reviewing exposure before adding helps prevent accidental crowding inside the portfolio.

Use catalysts and downside scenarios, not only upside

Sizing discipline is stronger when it includes what can go wrong: event risk, thesis age, liquidity, and tax consequences. SoloTerminal keeps those checks near the position so adds and trims happen with context.

Questions answered

Can SoloTerminal tell me the exact percentage to buy?

No. SoloTerminal helps you compare target weight, concentration, factor overlap, and catalyst risk, but the final size decision is yours.

Is position sizing the same as a price target?

No. A price target is a valuation view; position sizing is a portfolio-risk decision about how much of one idea you can afford to carry.

Why review factor exposure before adding?

Because several different tickers can still express the same underlying bet. Reviewing factor overlap helps prevent hidden concentration.

Size the next add with a written rule

Use one position to define target weight, overlap risk, and the condition that would stop you from adding more.
