How to Track an Investor’s Stock Picks

Track one identifiable person, firm, newsletter, or public account at a time. Similar display names and copied posts can merge different sources into a false record.

Keep the original handle and source identity attached to every call. If an account changes its name, preserve the historical identity instead of silently rewriting old records.

A trustworthy record begins with a consistent capture rule. Decide which public statements qualify, then apply that rule to bullish, bearish, losing, ambiguous, and unfinished ideas.

Do not build the dataset from viral screenshots or a portfolio page assembled after prices moved. That creates selection bias before performance is measured.

Investors can change their minds. Treat an added position, reduced target, invalidated thesis, or closed trade as a new event connected to the original call.

A revision should not overwrite the earlier statement. The sequence reveals how conviction changed and whether the change happened before or after the market supplied new information.

Use the same entry rule, outcome windows, and benchmark policy across investors. Separate unresolved calls from completed periods and show sample size beside any hit rate or average return.

No single score captures research quality. Read the underlying calls, risks, revisions, and return distribution before deciding whose work deserves attention.
