How this is calculated. We score only open-market purchases (SEC code
P) — the buys that carry real signal. Each trade's return is measured from the adjusted closing price on the purchase date to the latest close, accounting for stock splits and dividends. The 1M/3M/6M/12M columns show the same trade's return after each fixed holding period; a dash means that horizon hasn't elapsed yet or isn't priceable. Sales are excluded because insiders sell for many routine reasons. With only 4 scored trades, treat this as a small sample, not a verdict.

Frequently asked questions
What stock has Lin Elizabeth Yeu been buying?
Every open-market purchase (SEC code P) Lin Elizabeth Yeu has disclosed is in the feed above, newest first, with the ticker, share count, and dollar value. The scorecard nets these against sales and tracks how the buys have performed.
Where can I see Lin Elizabeth Yeu's Form 4 filings?
All of Lin Elizabeth Yeu's Form 4 transactions are listed above, each traceable to the original SEC EDGAR filing via the link on this page. Form 4 discloses insider buys and sells within two business days of the trade.
How is Lin Elizabeth Yeu's win rate calculated?
We take every open-market purchase (SEC code P) we can match to a stock price, then compare the split- and dividend-adjusted price on the purchase date to the most recent close. The win rate is the share of those buys currently trading above the purchase price. Sales and share grants are not scored.
Why are some buys not included in the score?
A purchase is excluded if we can't price it — for example if the ticker is missing from the filing, the company has been delisted, or the security isn't a common stock we can match to market data. Excluded counts are shown next to the scored total.
What do the 1M / 3M / 6M / 12M columns mean?
They show each purchase's return after a fixed holding period — one, three, six, and twelve months from the buy date — using split- and dividend-adjusted prices. This separates good entry timing from simply holding a long-running winner. A dash means that horizon hasn't elapsed yet for that trade, or the stock couldn't be priced at that date.
Does a high win rate mean I should copy this insider?
No. Past performance does not predict future results, sample sizes are often small, and an insider's edge in their own company doesn't transfer to yours. This is context, not a recommendation. InsiderSource is not investment advice.
Where does this data come from?
Trades come from Lin Elizabeth Yeu's SEC Form 4 filings on EDGAR. Prices come from public market data and are split/dividend-adjusted. Always verify against the original filings before acting.
