“Since alert” uses the price on the alert date. A 30-day peak is the highest price reached within 30 days, seen in hindsight; it is not a return anyone was guaranteed to capture. Older clusters, winners and losers, are in the full alert archive.
Once a month: clusters that have passed the 30-day mark since the last update are added. Fresh clusters are what subscribers pay for; once they are a month old they are published here and on the Results page, losers included.
Not on its own. In our backtest of 102,000 insider purchases, a typical lone insider buy did not beat small caps after costs, which is why ClusterSignal only looks at clusters. Some clusters are company-arranged share sales rather than conviction; see how to tell the difference. Sector matters too: which insider buys are worth following.
ClusterSignal watches public insider filings and emails a cluster alert when several insiders buy together. Informational only, cancel anytime.
