5 things to know before you start
Step 1
Who are the whales, and how do we know what they own?
Big US investment funds (like Warren Buffett's or Bridgewater) must report the stocks they hold to US regulators every 3 months, in a filing called a 13F. This site pulls the reports of about 50 whales and sums up who owns what, and who's adding or selling. Good to know: the reports come out roughly 45 days after the actual trades.

A good stock still needs a good price
Even if a whale owns it, buying after a big spike can leave you stuck at the top. So the system works out a 'buy zone' with 3 entry levels (E1–E3) from past support, moving averages and the whales' cost. When the price pulls back into the zone, the stock shows up on the 'Stocks to watch' page.

Always know your exit before you enter
Every stock has 3 targets (T1–T3) for taking profits step by step, and a stop-loss (SL): if the price closes below it, the plan was wrong and it's time to sell. Setting your stop-loss before you buy keeps a loss from getting so big that you miss the next opportunity.

Buy in steps, sell in steps
Split your money into 3 tranches and buy at E1, E2 and E3 as the price comes down to each, then sell in parts at T1, T2 and T3. That way you don't have to guess the exact bottom or top.

See the big picture before you decide
Each stock page sums up the 'Positives' and 'Risks', such as the long-term trend, whether whales are buying or selling, and upcoming earnings. Read them all before you decide, and only invest money you can afford to lose.

Glossary
Terms you'll see often on this site (tap the ⓘ button next to a term anywhere on the site to see what it means)
EPS = earnings per share. Before a report, analysts publish estimates; reporting above them is a “beat”, below is a “miss” (this site counts ±5% or more). The price often reacts sharply on day one, but revenue, company guidance and market expectations matter too — good results can still send a stock lower.
Officers, directors and 10%+ owners must report trades in their own company's stock to the SEC within 2 business days. An open-market purchase with their own money is often read as confidence; sales happen for many reasons (taxes, diversification, pre-planned 10b5-1 sales), so they carry less weight.
Three prices where the system sees a reasonable place to buy in stages, based on past support, moving averages and the whales' cost — E1 is closest to the current price, E3 the deepest.
Three prices where the system sees a reasonable place to take profits in stages, based on past resistance and the 1-year high.
If the price closes below this level, the plan was wrong — sell to limit the damage instead of letting the loss grow.
Higher is better. Based on how many whales hold the stock, how big it is in their portfolios, and whether they are buying more or selling.
The score used to choose “Today's picks”, combining the entry signal, whale score, trend, positives/risks and risk/reward.
Expected gain compared with the loss you accept. 1 : 3 means risking $1 to potentially make $3 — the higher the second number, the better.
Shows whether a stock has been bought or sold too much lately (0–100). Above 70 = overheated, may pull back · below 30 = heavily sold, may bounce.
The average price over a past period, e.g. MA200 = 200-day average. Used to read the trend — trading above the MA200 usually means a long-term uptrend.
Roughly how many dollars the stock moves in a typical day. Used to measure volatility and to space out entry and exit levels.
A report large US investment managers must file with the SEC every quarter listing the stocks they hold — published about 45 days after the quarter ends.
The average price during the period the whales bought this stock. It's an estimate, since the filings don't show actual purchase prices.
Positives minus risks found by the system — a rough overview, not a recommendation to buy or sell.
