Valuation answers “what is it worth?” Trade execution answers “how does that judgment become a position?”
Without valuation, buying and selling are just emotion. Without execution, valuation remains only an opinion.
Once money enters the market, several questions must be answered continuously:
- How should I buy?
- How much should I buy?
- How should I track the position?
- When should I sell?
- How should I sell?
Left-Side and Right-Side Trading
Left-side trading buys gradually near the end of a decline, when valuation is already low but trend has not reversed. It sells gradually during a rise when valuation is no longer cheap but the market is not yet overheated.
Its advantage is lower cost and more safety margin. Its weakness is that it requires tolerating floating losses, long bottoming periods, and the possibility of buying or selling early.
Right-side trading buys after trend confirmation and sells after trend deterioration. Its advantage is efficiency. Its weakness is that it may buy near local highs and sell during ordinary pullbacks.
Neither is inherently superior. Left-side trading tests valuation and patience. Right-side trading tests planning and discipline.
Do Not Mix Value and Trend Rules
Before each purchase, ask: what kind of money is this position trying to earn?
Is it earning money from business growth, valuation repair, and safety margin? Or from market heat, liquidity, and narrative expansion?
Both can be valid, but the rules are different. The most dangerous behavior is using one logic to buy and another logic to explain losses.
Using trend logic to buy, then saying “I will hold long term anyway” after a loss, is packaging failed speculation as value investing. Using value logic to buy, then applying trend stop-loss rules during normal volatility, is letting a voting machine judge a weighing-machine asset.
Value Investing Rules
At minimum, value investing should require:
- solid fundamentals and cash flow;
- reasonable or undervalued pricing;
- a path for earnings growth, cycle recovery, dividends, or market misunderstanding to be corrected;
- enough compensation for time cost;
- a margin of safety even in bad scenarios.
Holding depends on whether the original logic remains valid. Selling depends on fundamental deterioration, broken trust, extreme overvaluation, reaching the investment goal, or a better opportunity cost.
Core Claim
Valuation must become rules. Rules must become position behavior. Otherwise, market volatility will turn every investment thesis into an emotional improvisation.
