GOOD TO KNOW
Clear principles.
Straight answers.
What service do you offer?
We provide discretionary investment management for professional investors. Assets remain in brokerage accounts held in the client's name, with investment authority delegated to us. We can manage accounts at LS Securities, Korea Investment & Securities, Hyundai Motor Securities, Next Securities and other brokerages. We explain the connection process for your account during consultation.
Who can invest?
Our strategies are available only to eligible professional investors, including qualified individual investors. We verify eligibility before account opening.
How do you manage leverage and derivatives risk?
Some strategies, including Sentinel Global High, may use up to 3x leverage, inverse ETFs, futures and options. We reduce leverage when model confidence falls below our threshold. Portfolio managers may close positions under our daily loss-management rules. These measures do not prevent all losses or guarantee principal.
How do withdrawals and termination work?
There is no separate lock-up period. Withdrawal settlement takes five to seven business days. Outside the five-business-day voluntary cooling-off period, you may request additional deposits, partial withdrawals or full termination on business days. Please refer to your agreement for the specific terms.
Can I review the model's decisions and performance?
We combine model signals with portfolio manager review. Daily management reports explain key decision inputs, including model variables and confidence scores. Eligible investors can review live trading results from the firm's own accounts and detailed performance materials under a non-disclosure agreement. Separate materials describe the model architecture and training data coverage.
Where are client assets held?
Assets are held in brokerage accounts in each client's name, separate from the firm's own assets. Investment losses are borne by the investor and are not covered by deposit insurance. Your agreement and risk disclosures set out your rights and the relevant procedures.

Before you invest.
You may lose some or all of your invested capital. All investment losses are borne by the investor. Past performance, backtests and results from the firm's own accounts do not guarantee future returns.
Inverse and leveraged ETFs, futures, options and other derivatives can involve substantial volatility and losses. All strategies are intended for professional investors, whose eligibility must be verified before joining. Read the investment materials, risk disclosures and agreement, and consider your objectives, financial circumstances and capacity for loss.
