Many desks spend hours, if not days, putting together buys and sells across their portfolios, from constructing new portfolios and managing models to maintenance trading like investing cash, rebalancing accounts, and optimizing taxes. Finding optimal trades while staying compliant and minimizing drift is even more burdensome.
IMTC’s Optimizer is a decision support engine that enables portfolio managers to implement their best ideas. Input a group of accounts, an investment objective, and a bond universe to see CUSIP-level buys and sells that stay in line with guardrails.
- Run multi-factor optimization across multiple accounts
- Match account needs with live inventory or approved lists
- Maintain an audit trail with transparent, explainable, and repeatable results

Guardrails built into every decision
Individual portfolios with unique targets and rules are what make fixed income SMAs hard to scale. The better way to manage accounts is to embed targets and restrictions once, permissioned by role, and every decision stays in line automatically. As you mockup trades, you know you’re compliant long before you promote an order.
- Personalize every account, at any scale
- Stay compliant with hard restrictions and soft targets
- Manage account or strategy-level rules, built without code

Allocate bonds fairly across every account, pre-trade
Generate rule-based allocations across all accounts at once, whether a new issue or in secondary markets. Maintain fiduciary responsibility with systematic allocation logic that treats every account fairly and equitably: IMTC’s pro-rata and customizable waterfall methodologies determine which accounts need a bond and in what quantity.
- Determine precise allocations across accounts, in seconds
- Re-run allocations when you receive a partial fill
- Buy the block first, then allocate optimally to accounts in need

Surface the investment intelligence you need
Fast decisions start with the right insights already in front of you. IMTC surfaces what needs attention across your book and handles the routine work around it, from the moment your day starts through the ad hoc requests that come in throughout the day. Your team reviews and makes the decisions, the platform does the rest.
- Start each day with a dashboard to focus your attention, manage cash inflows, or address drift

FAQ
The best fixed income portfolio management software is built for the complexities and nuances of fixed income investing. A platform should let portfolio managers construct and optimize across multiple accounts at once and automate rebalancing and maintenance trading workflows. Portfolio management software should also embed each account’s investment rules and targets, surface cash and drift automatically, and allocate bonds equitably to uphold fiduciary responsibility. Full connectivity into existing systems, along with tools designed for fixed income management, keeps analysis and action in one platform rather than spreadsheets. IMTC is purpose-built for fixed income managers running SMAs at scale.
The best software for managing fixed income SMAs at scale is built to run hundreds or thousands of customized accounts as one book simultaneously, not one account at a time. A platform should be designed to take action: construct and optimize across every account at once, enforce each account’s unique guidelines automatically, and automate the daily work of investing cash, managing drift, and maintenance trading. Technology for managing SMAs should extend capacity without adding headcount for every new block of accounts, or allow firms to launch new strategies without hitting bandwidth issues. IMTC is purpose-built for fixed income managers growing their SMA business at scale.
A fixed income portfolio optimizer should deliver optimal buys and sells across many accounts while also considering many constraints at once (duration, sector, credit, cash, tax, and each account’s rules). Portfolio managers should be able to optimize to a specific objective and view transparent, explainable, and repeatable results. It should also automate daily workflows, turning hours of manual work into minutes. IMTC’s Optimizer is built to do all of this, so portfolio managers can act quickly and with confidence.
Personalizing bond portfolios at scale means tailoring every account to its own objectives and customizations without the work multiplying as the complexity grows. A portfolio management system should let managers set each account’s guidelines, targets, restrictions, and cash needs once, then enforce them automatically on every decision. Those rules should apply across hundreds of accounts or strategies at the same time, also allowing for the use of characteristics-based models, so customization never comes at the cost of scale. IMTC is purpose-built for fixed income managers to customize portfolios for every client at scale, from straightforward mandates to the most sophisticated fixed income strategies.
IMTC is purpose-built for separately managed accounts and individual bond accounts, from model-based portfolios to fully customized ones, across taxable and tax-exempt strategies. That spans the assets fixed income managers actually run: municipal bonds, investment grade and high yield corporates, Treasuries, government agency securities, and structured products. The platform is also wrapper agnostic, allowing firms to manage mutual funds and ETFs, and it supports multi-asset portfolios by tracking top-level equity and fund holdings alongside the fixed income sleeve. Each account carries its own investment guidelines, targets, cash needs, and restrictions, all enforced automatically.
