A high water mark (HWM) is the highest account value a fund or managed account has reached. A manager earns a performance fee only on profit above that peak. If the account falls and then recovers, no fee is charged on the recovery. Fees resume once the account passes the old high.
This guide explains the mechanism, walks through numbers, covers the edge cases that cause disputes, and then answers a related question traders ask: how stop orders (hard or soft, server-side or client-side) affect drawdowns and therefore the high water mark.
TL;DR
- A high water mark is the peak account value. Performance fees apply only to gains above it.
- Recovering a loss earns the manager nothing. Only new profit above the mark is shared.
- The HWM is not a guarantee. Deep losses after early gains can still leave an investor paying fees on a weak overall record.
- Deposits, withdrawals and look-back periods change how the mark works. Read the fee terms before funding an account.
- Stop orders held on the broker server keep working if your device disconnects. Orders held in local software may not.

What a high water mark means
The high water mark is the peak net asset value, or account value, that an investment fund has ever achieved. It exists so that managers receive performance fees only on new profits above that historic high. The investor does not pay twice for the same money: once when it was first earned, and again when it is won back after a loss.
The term comes from hedge funds, where a base management fee is usually paired with a performance fee. Investor.gov notes that hedge fund investors typically pay a base asset management fee of 1% to 2% of net assets on top of performance fees. The same logic is now used in managed accounts and copy trading, where a strategy provider is paid a share of profit.
Why it exists
Without an HWM, a manager could gain 20%, lose 20%, gain 20% again, and collect a fee on each upswing while the investor ends the period roughly flat or lower. The mark removes that incentive. Academic work on the topic describes HWM-linked fees as an agency tool that aligns manager and investor interests, though the fit is better for aggressive investors than for conservative ones.
Not every fund has one
An HWM is common but not universal. A CFA Institute blog post reports that roughly one-third of hedge funds do not use one. With those funds, an investor can pay performance fees without having made any new net gain. When you evaluate any managed strategy, ask for the fee terms in writing and check whether a mark applies.
High water mark example: loss, recovery and fee
Numbers make the mechanism clear. Take a simple case first.
A $1,000,000 account loses 20% and falls to $800,000. It then gains 25% and returns to exactly $1,000,000. Because the old peak was only recovered and not exceeded, no performance fee is charged. Note that a 25% gain is needed to repair a 20% loss, which is why drawdown size matters so much.
Now extend it. The account gains a further 10% and reaches $1,100,000. That is $100,000 of new profit above the $1,000,000 mark. With a 20% performance fee, the fee is $20,000, and the new high water mark becomes $1,100,000.
A longer example with several steps
This one follows the sequence from Investopedia: an investor puts in $500,000 and the manager charges a 20% performance fee.
| Step | Account value | Fee charged | High water mark after |
|---|---|---|---|
| Start | $500,000 | None | $500,000 |
| 15% gain | $575,000 | $15,000 | $575,000 |
| 20% loss | $460,000 | None | $575,000 |
| Recovery to old peak | $575,000 | None | $575,000 |
| Rise to $690,000 | $690,000 | $23,000 | $690,000 |
The $23,000 fee applies only to the $115,000 above the old mark. Total fees over the period are $38,000, as the Investopedia walkthrough shows. The recovery from $460,000 to $575,000 generated $115,000 of growth for the investor and no fee for the manager.
If you want to build your own versions of this table, scenario modeling tools help. Scenario modeling for investment plans lets you compare how account values change when a portfolio falls below a prior peak and then climbs back.
The recovery math behind it
The deeper the drawdown, the longer the road back to the mark. A 50% loss needs a 100% gain to recover. We cover that arithmetic in why a 50% loss takes a 100% gain to recover. A strategy with small drawdowns spends less time under water, so its mark is reset more often and fees are tied more closely to real progress.
How the mark is adjusted in practice
The textbook version is simple. Real contracts add details, and those details decide who pays what.
Deposits and withdrawals
A new deposit raises the account value without being profit. A fair agreement adjusts the mark upward by the deposit, so the added money is not counted as a gain. A withdrawal does the reverse: it should not be treated as a loss. If the terms do not say how this works, disputes follow. A professional paper on performance fees warns that missing parameters, such as whether returns are time-weighted or money-weighted, can lead to significant investor-manager disputes.
Look-back periods and loss carry-forward
Some systems do not track one all-time peak. Interactive Brokers describes a method in which gains first reduce carried-forward losses, and fees apply only after those losses are recovered within the configured look-back period. A short look-back means old losses expire sooner, and a fee can become payable before the account is back at its peak. Always ask how long losses stay on the books.
Fee timing
Fees can be calculated daily, monthly, quarterly or annually. Crystallization frequency changes results. A fee charged only at year end can net out intra-year swings. A monthly fee may take a share of each rise before a later fall. Check the schedule in the fee terms.
HWM versus hurdle rate
These are different protections. The HWM stops fees on recovered losses. A hurdle rate is a minimum return the fund must earn before any performance fee is triggered. Some agreements use both. One research note describes a fund whose value must first reach its historical high and then rise a further 5% before fees apply.
What a high water mark does not do
The mark is a fairness rule, not a performance guarantee. The CFA Institute piece points out that even with an HWM, investors may pay performance fees on a poor-returning fund when deep losses follow early successes. Here is how that happens: a fund doubles, pays fees on the gain, then loses 40%. The investor is down from the peak, yet the fee on the first rise was already paid.
Incentive fees are also asymmetric. Managers share in gains but not in losses, which can encourage risk-taking. The HWM reduces this problem. It does not remove it. That is why investors should look at drawdown and recovery together with the fee terms.
Useful tools for this review:
- Recovery factor compares net profit with the worst drawdown.
- Equity curve analysis shows how often an account makes new highs and how long it spends below them.
- Maximum drawdown shows the depth of the worst fall and the gain needed to recover.
A checklist before you fund a profit-sharing account
- Is there an HWM? Ask for the clause, not a summary.
- How is it adjusted? Confirm treatment of deposits and withdrawals.
- What is the fee rate and schedule? Know the percentage, the calculation period and when fees are deducted.
- Is there a look-back limit? Learn how long losses carry forward.
- Is the record verified? Look for third-party tracking, not screenshots. Our guide to verifying an 18 month track record lists what to check.
- How are splits calculated? Some profit-sharing setups hide costs in how the split is measured. See the hidden split in profit sharing.
No fee structure is a reason to invest on its own. Trading gold and other leveraged instruments carries a risk of losing part or all of the capital you commit. Past results do not predict future ones. If you are unsure how a fee clause applies to your situation, ask a licensed financial adviser or a qualified accountant in your country.
Hard stop vs soft stop, and server vs client stops
Traders who ask about high water marks often ask about stops too, because stops shape drawdowns, and drawdowns decide how long an account stays below its mark.
Hard stop vs soft stop
A hard stop is a stop-loss order placed with the broker. It is an instruction to sell a security when its price falls to a set level. It limits losses but does not guarantee the exit price: in a fast market or a gap, the fill can be worse than the stop level. A soft stop is a level the trader or software watches, with the exit decided and sent manually or by a program once the price touches it. It allows judgment, but only if something is running and someone acts.
Server-side vs client-side stops
The difference is where the order lives. A server-side stop is stored on the broker's server. It stays active if your computer shuts down, your phone loses signal or the app closes. A client-side stop depends on software on your own device, and if that software stops running, so does the monitoring. If your connection fails, only the first type is certain to remain in place. Confirm with your broker which type each order is, since platforms differ and some advanced order types run locally.
For automated copy trading this matters even more. A hands-off setup should not depend on your laptop being awake. Choose arrangements where protective orders sit on the broker side, and set an account-level cap as well. Our article on daily loss limits shows how to set and enforce one.
How this applies to gold copy trading
Gold (XAUUSD) moves fast, so drawdown control carries much of the weight in a profit-sharing arrangement. Sonic AI is an auto-trading strategy focused only on gold, copied through COPYX. Our published position is a win rate of about 80% and drawdown under 1% across 18 consecutive winning months, with results shown on MyFXBook. These are our own claims, and you should check the live record yourself. Our piece on low drawdown strategy shows what the numbers cover. Our backtest vs live trading analysis compares signals with real fills.
A low drawdown shortens the time an account spends under its prior peak. Under a high water mark model, that keeps the fee tied to steady, new profit. The exact fee terms for Sonic AI are on the performance fee page. Read them in full, including how the fee is calculated, before you fund an account.
Our perspective
We built Sonic AI around one idea: an account should earn its fees. For us, that means a strategy that makes new profit, keeps losses small and shows every result in public.
A high water mark is a good test of any fee model. It forces a question: does the manager get paid for progress, or for movement? A strategy with deep swings will often work below its mark for long stretches. A strategy with small drawdowns reaches new highs more often.
This is why we focus only on gold and manage drawdown first. Our claimed drawdown is under 1% across 18 verified winning months, and the record is on MyFXBook for anyone to inspect. We ask investors to check it, compare it with the fee terms and decide for themselves.
Automation matters too. COPYX copies trades without manual steps, so execution does not depend on a user's mood or screen time. That suits new traders and busy professionals alike.

FAQ
What does high water mark mean in trading?
It is the highest value an account or fund has reached. A manager can charge a performance fee only on profit above that level. Losses must be recovered first, so the investor does not pay twice for the same gains.
Does a high water mark reset?
It moves up each time the account closes at a new peak and the fee is charged. Whether it ever resets down depends on the contract. Some agreements use a look-back period after which old losses no longer count, so read that clause closely.
How do deposits and withdrawals affect the high water mark?
A fair agreement adjusts the mark for them, so a deposit is not counted as profit and a withdrawal is not counted as a loss. Contracts differ, and unclear wording is a common source of disputes. Ask for the calculation method in writing.
Is a high water mark the same as a hurdle rate?
No. A high water mark stops fees on recovered losses. A hurdle rate sets a minimum return before any fee applies. Some funds use both together.
Will my stop loss work if my internet goes down?
A stop held on the broker's server stays active when you disconnect. A stop that depends on software on your device may not. Confirm with your broker how each order type is handled, and remember that fills can slip in fast markets.
