Evaluating anyone who sells a strategy

In short

I once watched a neighbor hand over two thousand dollars for a trading course because the instructor's website showed a chart climbing steeply to the right. Six months later the neighbor had less money and no clear idea why the method had stopped working. A person who sells a strategy, whether on social media or through a paid newsletter, earns money from that sale instead of earning it from the strategy itself. That difference matters. You want to see at least three years of audited returns before you trust a claim, and you want to know whether the person risked their own capital. Ask what the strategy cost in fees, taxes, and time. Ask whether it worked during a downturn, not only during a rally. If the seller cannot answer those four questions clearly, you are looking at marketing rather than a record.

The whole of it

What it is

I once sat across from a man who promised he could double my account every eighteen months. When I asked to see his own brokerage statement, he changed the subject. That moment taught me more than any prospectus ever did. Evaluating anyone who sells a strategy is the skill of separating a tested method from a story designed to separate you from your money. It is not about doubting every voice; it is about asking the same questions a bank would ask before lending money on a business plan. A strategy is only as real as the evidence behind it.

The term strategy here means any repeatable approach to investing, trading, or managing money that someone offers to teach or license. The term sell includes charging for access, earning affiliate commissions, or profiting from attention even when the instruction itself is free.

How it works

You start by recognizing the incentive structure. Someone who makes money by describing a strategy earns whether or not you profit from following it. That is not dishonesty; it is simply how teaching and publishing work. But it does mean their income is decoupled from the results they promise you. A fund manager whose own wealth sits inside the fund has a different incentive than a newsletter writer whose wealth comes from subscription renewals.

The first filter is time. You want a verifiable record covering at least three full years, because that span usually includes at least one period of falling prices or rising uncertainty. A strategy that sparkles for nine months may only be catching the tailwind of a rally. Look for returns that were calculated by an independent auditor or published in a format you can check transaction by transaction. Screenshots of account balances are nearly worthless; they can be altered or cherry picked.

The second filter is the seller's own capital. Ask whether the person teaching the strategy is risking a meaningful portion of their net worth on it. Meaningful means enough that a loss would change their life, not a token amount set aside for demonstration. If they refuse to answer or say they prefer to keep business and personal separate, you have learned something valuable.

The third filter is total cost. A strategy that returned eighteen percent before fees, taxes, and time might net you six percent after all three. Ask for a full accounting: brokerage commissions, platform fees, subscription costs, the seller's cut, short term capital gains rates if the method trades frequently, and the hours per week required. Then compare that net figure to a simple default, such as a low cost stock index fund.

The fourth filter is drawdown. Every strategy loses money during some stretch. You want to know the worst peak to trough decline the strategy endured, how long it lasted, and whether the seller stuck with the method during that span. If the answer is that the strategy avoids losses entirely, you are hearing marketing.

The numbers, and where to find yours

There are no regulatory limits to check here, only benchmarks you set. A reasonable standard is that the strategy should beat a relevant index by at least the current figure, which the official source publishes each year after all costs over a full market cycle, which usually spans five to seven years. The figure the current figure, which the official source publishes each year is the long run average annual return of the S&P 500, a common baseline for U.S. stock strategies. You can find current estimates on the investor page of any major index provider.

If the seller cites returns, ask for the time weighted return and the internal rate of return. Time weighted return shows how the strategy performed; internal rate of return shows how an investor's actual dollars grew when accounting for the timing of deposits and withdrawals. A large gap between the two can signal that the strategy requires perfect timing or that early results were stronger than recent ones.

You will not find your own numbers until you try the strategy, but you can model them. Take the claimed return, subtract estimated taxes at your marginal rate, subtract all stated fees, and subtract an hour of your wage for every hour the method demands each week. If the result is still appealing, ask for introductions to three clients who have followed the method for at least two years.

A worked example

Maria finds a video course promising a covered call strategy that generates two percent income per month. The course costs eight hundred dollars, and the instructor shows a brokerage screenshot with a balance that has doubled in a year. Maria pauses and works backward. Two percent monthly compounds to more than the current figure, which the official source publishes each year annually, which is far above the current figure, which the official source publishes each year. She searches for the instructor's name and finds no audited track record, no disclosure of personal holdings, and no mention of how the strategy performed in early 2020 when volatility spiked.

She emails to ask four questions. What were the worst three months in the past three years? What do you personally have invested in this approach? What does the strategy cost in commissions and taxes for someone in the the current figure, which the official source publishes each year federal bracket? Can you introduce me to someone who has used it for two years? The instructor replies with enthusiasm but does not answer the third or fourth question. Maria concludes the course is an income stream for the instructor, not evidence of a repeatable edge, and she skips it.

A year later she meets another educator who publishes a yearly letter audited by a regional accounting firm, showing returns over seven years with every drawdown listed. The educator owns the strategy in their own retirement account and caps enrollment when capacity fills. Maria pays for a trial quarter, tracks every trade, and calculates her own after tax return. It beats the index by a percentage point after costs. She continues.

Where it goes wrong

The most common mistake is accepting a short window of success as proof. You see eighteen months of gains and assume the pattern is durable. But eighteen months is barely a test. The second mistake is trusting charisma over documentation. A compelling speaker with a confident stage presence can make a weak strategy feel bulletproof. The third mistake is ignoring survivorship bias. The sellers you hear from are the ones whose track records let them keep marketing; the ones whose strategies failed have moved on to other work, and you will not find their cautionary tales in a web search. The fourth mistake is underestimating the tax and time cost. A strategy that demands two hours of research each evening may cost you more in lost rest or family time than it delivers in returns.

Another error is assuming that past audited returns guarantee future results. They do not, but they do tell you that the strategy existed, that someone measured it honestly, and that it survived conditions you can read about and understand. Finally, people mistake disclosure for alignment. A seller who admits they earn affiliate commissions has disclosed a conflict but has not resolved it; you still do not know whether their endorsement reflects performance or payment.

Questions to answer before you leave this page

Can you name the independent auditor or custodian who verified the returns over the past three years? Do you know the seller's worst monthly loss and how they responded to it? Have you calculated the after tax, after fee return assuming your own marginal rate and holding period? Do you know how many hours per week the strategy requires and what that costs you in other terms? Have you spoken to anyone outside the seller's promotional network who has used the strategy through a market decline? Can you describe in one sentence why this strategy should outperform a simple index over the next decade? If you cannot answer five of those six, you are not yet evaluating; you are still shopping.
