Investor risk guides in plain English.

Plain-English guides on profit protection, stop placement, volatility, portfolio concentration, re-entry timing, and disclosure research.

Exits & profit protection

Profit protection: a practical guide to keeping more of your gains

A practical framework for deciding, in advance, how much profit you are willing to give back before you exit, and how to set a level that survives normal noise.

Stop loss vs profit lock: what is the difference?

A stop loss caps the downside from your entry; a profit lock protects a gain you already have. Same mechanism, different question, and the answer changes where you place the level.

ATR stop-loss explained in plain English

An ATR stop places your exit a multiple of the stock’s recent daily range away from price, so calm stocks get tight stops and jumpy ones get room, automatically.

Chandelier Exit: trailing stops for protecting strong trends

The Chandelier Exit hangs below the recent high by a volatility-adjusted distance, so your exit rises as a trend makes new highs, locking in profit while letting winners run.

Volatility primer: how price movement shapes every exit

Volatility, how much a price moves, not which way, is the single input that ties together stop distance, position size, quality grading, and re-entry timing across PnLock.

Portfolio risk

Portfolio concentration risk: how hidden exposure builds up

A portfolio can look diversified by ticker count while quietly depending on a handful of underlying exposures. Concentration risk is about what you really own, not how many lines you hold.

Re-entry timing

When to re-enter a stock after getting stopped out

Re-entry works best as an evidence checklist, not an emotional reaction to one green candle. A few objective checks keep you from catching a falling knife, or missing a real recovery.

Disclosure research

Insider buying signals: what investors should and should not assume

Insider buying can be useful context because insiders only profit from open-market purchases if the stock rises, but role, clustering, and disclosure limits all change how much weight a filing deserves.
