Less Is More

A watchlist is not a list of every stock that catches your eye. It's a carefully curated collection of companies you've researched, understand, and would buy if the price were right. A quality watchlist of 15-25 stocks beats a scattered list of 100 names you barely know.

Step 1: Define Your Criteria

Before adding any stock, know what you're looking for. Write down your filtering criteria — the non-negotiable qualities every stock on your list must have. This might include:

Market cap above $2 billion (no microcaps)
Revenue growth above 10% annually for the last 3 years
Consistent profitability (no money-losing companies)
ROE above 15%
Debt-to-equity below 1.0
Insider ownership above 5%
Business you can explain to a 12-year-old in one sentence

Your criteria reflect your strategy. A value investor's criteria look different from a growth investor's. That's fine — but have criteria and stick to them.

Step 2: Screen and Filter

Use stock screeners (Finviz, Tikrr screens, your broker's research tools) to generate a list of candidates matching your criteria. This narrows thousands of stocks to a few dozen. Don't add everything that passes the screen — the screen generates candidates, not decisions.

Step 3: Tier Your Watchlist

Organize your watchlist into tiers:

Tier 1 (High Conviction) — Companies you've researched deeply. You understand the business model, competitive advantage, financials, and management. You own or would buy immediately if the price dropped to your target. Limit to 5-10 names.
Tier 2 (Monitoring) — Companies that look interesting but need more research, or great companies that are currently too expensive. You check these periodically for updates. 10-15 names.
Tier 3 (To Research) — Names that came up in screens, articles, or conversations. You haven't done deep work yet. This is your research queue.

Step 4: Track Catalysts and Price Targets

For each Tier 1 stock, note:

Your buy price — The maximum you'd pay for a margin of safety.
Key catalysts — Upcoming events that might move the stock: earnings dates, product launches, FDA decisions, contract announcements.
Your sell conditions — What would make you sell? Price target reached? Thesis broken? Better opportunity elsewhere? Write it down before you own the stock — you won't think clearly after.

Step 5: Maintain and Prune

Review your watchlist quarterly. Remove stocks where the thesis has changed, the financials have deteriorated, or you've lost conviction. A watchlist is a living document, not a collection to be hoarded. The goal is to have a small list of high-conviction ideas you actually act on, not a long list of stocks you vaguely like.

Key Takeaways

Define written criteria for your watchlist. If a stock doesn't meet them, don't add it.
Organize into tiers: high conviction, monitoring, to-research. Focus on the top tier.
Track buy prices, catalysts, and sell conditions for each Tier 1 stock. Prune quarterly.
