5.8. Copying Analysts, Influencers, or Friends
Lesson objective
Keep responsibility for the decision.
Other people may have different goals, time horizons, information, or entry prices. They may also have conflicts of interest.
Opinions can help discover arguments, but they should not replace research. Look for primary sources and opposing evidence.
A public recommendation may arrive after the price has already moved.
Borrow ideas; never outsource the reasoning
An analyst, influencer, friend, or famous investor may surface a useful company. Their conclusion still cannot substitute for your own context.
Two people can rationally make different decisions about the same stock because they have different:
- purchase prices and expected returns,
- time horizons,
- portfolio concentration,
- tax situations,
- liquidity needs,
- risk capacity,
- information and analytical edge.
Use a source test
Claim → Evidence → Date → Assumptions → Incentives → What would disprove it?
The same stock, a different decision
An investor who bought at $40 and now holds at $100 may still be comfortable because the business compounded faster than expected. A new investor considering the same $100 price faces a different forward return. Copying the holder's decision ignores the entry valuation.
A credible source should make your research more efficient or more challenging, not make independent verification unnecessary.
What you should remember
- Ask for evidence and confirm the date.
Practice
Take one public opinion and identify the source, assumptions, date, and possible conflict of interest.
