Reactor for the investor managing a portfolio

Understand your holdings and keep track of them

You have an investment portfolio, or positions you hold over time. Maybe you pick investments yourself, use recommendations, or only check the account now and then.

You want to understand what's happening in the portfolio, where the risk is concentrated and which changes need attention — without gathering and analyzing all the information yourself.

Reactor is a trading operating system that brings together AI, market data and your investment accounts. You can use it to analyze the portfolio, examine specific holdings and keep regular track. You can also give Agents analysis and management tasks, with the judgment and permissions you define.

The examples below show a few ways to use the system.

EXAMPLE 1

Get a clear picture of the portfolio

"I can see the holdings in my account, but it's hard to understand the overall picture."

You can ask Reactor to read the holdings in the connected account and summarize them: what you hold, the size of each position, the profit or loss, and how the money is split between assets.

From that picture you can move on to questions: which holding affects the portfolio more? Where is there a large concentration? What's worth checking in depth?

Holdings in the account
Summary
Deeper look at one point
WHAT YOU'LL SEE
A snapshot of an account, a summary of the holdings, and a follow-up analysis of one key point from the summary.
Questions that may come up
How is this different from my broker's screen?
The broker shows the account status. Reactor lets you ask questions about the data, get explanations and bring it into further analysis.
Can I ask in plain language?
Yes. For example: "Explain where my money is concentrated and which holdings affect the result most."
Does the analysis change anything in the portfolio?
An analysis request shows information and conclusions. Taking an action requires a task and the right permissions.
✓ HOW WILL I KNOW I GOT IT?
You can identify the main holdings in the portfolio and which question is worth checking next.

EXAMPLE 2

Understand where the risk is concentrated

"I have several investments. Does that mean my portfolio is diversified?"

The number of holdings alone doesn't explain diversification. A large part of the money may sit in one asset, or several holdings may be affected by the same sector and the same market conditions.

Reactor can calculate the weight of each holding from the account data and help check concentration. Analyzing the links between assets depends on the information available; when more is needed, we'll show what's missing.

Number of holdings
Doesn't explain diversification on its own
Weight and concentration
Where the money actually sits, and what moves together
WHAT YOU'LL SEE
The portfolio split by holding weight, and an analysis of one concentration that deserves attention.
Questions that may come up
Is a large concentration necessarily a problem?
It can be a deliberate choice. You need to understand how it fits your goal and what a change in that holding would do.
Can the system suggest a change?
You can ask it to examine alternatives and explain the considerations. A suggestion should take into account the goals and limits you set.
Can I see several accounts together?
You can examine connected accounts according to the data and capabilities available, while keeping the distinction between them.
✓ HOW WILL I KNOW I GOT IT?
You can explain which concentration in the portfolio is deliberate, and which one you'd like to re-examine.

EXAMPLE 3

Examine a holding before deciding what to do with it

"I have an asset that went up or down a lot. I don't know whether to hold, add or reduce."

You can give Reactor a focused task: check the position, gather the relevant market data and weigh several options.

For the analysis to fit you, add the context: why you bought, how long you meant to hold, and what matters to you in the decision. A long-term investment and a short trade may need different analysis.

HoldAddReduceExit
WHAT YOU'LL SEE
An existing position, the goal set for it, and a comparison of holding, adding, reducing or exiting.
Questions that may come up
Does the system know why I bought?
You need to provide that context, if it isn't recorded in the information available to it.
Does it take my investment horizon into account?
You can set it in the instructions and ask for the analysis to take it into account.
Can it use judgment?
Yes. You can ask it to weigh data, explain the alternatives and give a reasoned conclusion within the frame you set.
✓ HOW WILL I KNOW I GOT IT?
You can identify which data supports each option, and what might change the conclusion.

EXAMPLE 4

Get a regular update on what needs attention

"I don't want to check every holding every day, but I don't want to miss an important change either."

You can set up an Agent that runs a periodic check of the portfolio. It can summarize the state of the holdings, check conditions you defined, and flag cases that need a look.

The Agent can combine clear alert thresholds with judgment. For example, telling routine fluctuation apart from a change that justifies further analysis, according to your instructions.

Periodic check
Your conditions
What needs attention
WHAT YOU'LL SEE
A short periodic summary, and one holding the Agent chose to draw attention to, with an explanation of why.
Questions that may come up
How does it know what matters to me?
You define the goal of the tracking, the relevant holdings and the situations you care about. You can start from a ready-made example and adapt it.
Can I get an update only when something significant happens?
You can define reporting conditions, depending on the plan and the tools you use.
How does it know what changed since the last check?
A comparison needs a recorded, available reference point. In the demo we'll show which data the comparison relies on.
✓ HOW WILL I KNOW I GOT IT?
You can explain what the Agent tracks, and which kind of change should trigger an update.

EXAMPLE 5

Check a change to the portfolio before making it

"I'm thinking of selling part of a holding or adding an investment. How will it affect the portfolio?"

You can examine the arithmetic effect of a planned action: how much money will move, what the holding's weight will be afterwards, and how the portfolio split will change.

You can also define price scenarios and calculate their effect on the holdings. A scenario explains what happens if the assumptions hold; it isn't a forecast that they will.

The portfolio today
Current weights and split
After the change (calculated)
New weights, plus the assumptions behind them
WHAT YOU'LL SEE
The portfolio as it is today versus a calculated state after a specific change, with the assumptions the calculation is based on.
Questions that may come up
Can I compare several alternatives?
Yes, depending on the data available. For example, a small reduction versus a large reduction of the same holding.
Does the calculation include tax and fees?
It should state which costs were included. Information about your personal tax doesn't come from position data alone.
Can I carry out the action through Reactor?
On supported accounts and assets you can move from analysis to an action plan and execution, with the right permissions.
✓ HOW WILL I KNOW I GOT IT?
You can explain what changes in the portfolio under each alternative, and which assumptions still need checking.

EXAMPLE 6

Set up an Agent to manage positions

"I want the system to help manage holdings, but it matters to me to control what it does."

You can give an Agent a role of tracking or managing positions. For example, checking protections, considering partial profit-taking, or suggesting a reduction when certain conditions are met.

The instructions should fit the nature of the holding and your goal. You choose whether the Agent only reports, asks for approval, or is allowed to carry out defined actions.

Reports onlyAsks for approvalCarries out defined actions
WHAT YOU'LL SEE
The same management task at different levels of independence, alongside the data and reasoning for a suggested action.
Questions that may come up
Do I have to allow automatic trading?
You can use analysis and tracking only, and keep the decisions and execution in your hands.
Can I limit it to specific holdings?
We'll define the scope of the task and see which limits and permissions are available in the relevant plan.
How will I know what was executed?
You can go through the runs and actions and check the actual state of the account.
✓ HOW WILL I KNOW I GOT IT?
You can explain which actions the Agent is allowed to take, and which decisions need your approval.

EXAMPLE 7

Understand the portfolio's performance over time

"The portfolio went up or down. I want to understand what contributed to the result."

You can research which holdings contributed to profit and loss, and look separately at the results of closed trades and of positions still open.

To calculate return over a period you also need the relevant account history, including deposits and withdrawals. That way you don't confuse a change in balance with investment performance.

Realized profitUnrealized (paper) profitMoney movements in the account
WHAT YOU'LL SEE
The result broken down by holding or trade, separating realized profit, paper profit and money movements in the account.
Questions that may come up
Does a higher balance mean the portfolio made money?
Part of the increase may come from a deposit. You need to separate money movements from investment results.
Can I compare to a previous period?
Yes, when the data for both periods is available and they can be calculated on a consistent basis.
How do I use the analysis to improve?
Identify what contributed to the result, examine the decisions behind it, and define what's worth checking or tracking next.
✓ HOW WILL I KNOW I GOT IT?
You can explain what contributed to the change in the portfolio, and which part of the result still depends on open positions.
