The full impact of any investment decision — visible before you make it.

Every investment decision reshapes your portfolio in ways that aren't always obvious. Ziggma's Portfolio Optimizer makes them visible — across diversification, quality, risk, impact, and yield — before you act.

Used extensively by independent investors who want to invest with both discipline and purpose.

Five dimensions. One simulation.

Every trade you simulate is instantly evaluated across five portfolio dimensions — so you see the full picture before you commit.

◎
Diversification
See if a trade increases concentration risk

The optimizer flags if a new position would push your largest holding above healthy thresholds — and shows which stocks dominate your allocation today.

☆
Portfolio Quality
Know if you're adding strength or diluting it

Ziggma scores every simulated addition against a fundamentals-based quality framework — profitability, growth, balance sheet health, and valuation — and shows the net effect on your portfolio score.

🌿
Impact Score
Invest in line with what you stand for

See how each simulated trade shifts your portfolio's real-world impact profile — environmental footprint, social responsibility indicators, and overall sustainability alignment.

⚡
Risk
Spot hidden risk before you take it on

The optimizer measures portfolio beta and flags the highest-risk positions by name. A simulated trade that lowers overall beta is a meaningful signal — and you'll see it instantly.

$
Portfolio Yield
Understand the income impact of every move

See how adding or selling a position affects your portfolio's overall dividend yield — including which holdings contribute least. Make income-aware decisions, not just return-focused ones.

From trade idea to confident decision — in minutes

The Portfolio Optimizer gives you a structured process for every investment move.

Step 1
Connect your accounts

Link your brokerage and retirement accounts. Ziggma aggregates your full portfolio into a single view — including accounts held at different brokers.

Step 2
Enter a trade to simulate

Choose Buy or Sell, search for any stock or ETF, and enter a price and quantity. The optimizer instantly shows the projected impact across all five dimensions.

Step 3
Explore smarter alternatives

Not sure you've found the best trade? Use High-Scoring Peers, High-Impact Peers, Low-Risk Ideas, or High-Yield Ideas to discover better alternatives ranked by Ziggma Score.

Step 4
Execute through your broker

Once you're confident the trade improves your portfolio, execute it through your existing broker. Ziggma is brokerage-independent — it gives you the analysis, you place the trade.

Two features most investors don't know exist

Beyond the simulation, the Portfolio Optimizer includes tools that actively help you find better trades.

Instant Simulation

See the full impact of any trade — before you place it

Most brokers show you a trade confirmation after the fact. Ziggma shows you the consequences before you act. Enter any buy or sell, and the optimizer instantly recalculates all five portfolio dimensions in real time.

  • Impact on diversification and top-holding concentration
  • Net change to portfolio quality score
  • Shift in beta and overall risk profile
  • Effect on impact score and sustainability alignment
  • Change to portfolio yield
High-Scoring Peers

Don't just simulate — discover a better trade

Not sure if you've found the right stock? The optimizer surfaces ranked alternatives based on what you actually care about. Every suggestion is scored by Ziggma — no guesswork, no noise.

  • High-Scoring Peers — fundamentally stronger alternatives
  • High-Impact Peers — better sustainability alignment
  • Low-Risk Ideas — positions that reduce portfolio beta
  • High-Yield Ideas — income-focused alternatives
  • Each suggestion ranked by Ziggma Score out of 100

Frequently asked questions

Everything you need to know about Ziggma's Portfolio Optimizer.

A portfolio optimizer is a tool that helps investors evaluate how a potential trade would change their portfolio's structure before they execute it. Ziggma's Portfolio Optimizer simulates any buy or sell across five dimensions — diversification, quality, impact, risk, and yield — so you can invest with more clarity and less guesswork.
Most brokers show you the impact of a trade after you've already placed it — in the form of a trade confirmation. Ziggma shows you the full projected impact before you commit. That's a fundamental difference for anyone serious about portfolio quality and long-term performance.
When you run a simulation, Ziggma can surface alternative stocks that score higher on the Ziggma Stock Score than the position you're evaluating. These are fundamentally stronger alternatives in the same general category — giving you a starting point to find a better trade, not just validate the one you already had in mind.
Yes. You can simulate buying or selling both individual stocks and ETFs. The optimizer will show the projected impact on all five portfolio dimensions regardless of the security type.
Yes. Ziggma aggregates your holdings across all connected brokerage and retirement accounts into a single consolidated portfolio view. The optimizer runs against your complete picture — not just one account in isolation. See how to track investments across multiple accounts.
The Ziggma Stock Score is a fundamentals-based quality score that evaluates every stock on a 0–100 scale across profitability, revenue growth, balance sheet health, and valuation. It powers the optimizer's quality dimension and all peer suggestions — giving you an objective, consistent standard to evaluate any position.
The impact score reflects how well your portfolio aligns with positive real-world outcomes — environmental performance, social responsibility, and sustainability positioning. When you simulate a trade, Ziggma shows whether the new position would increase or decrease your overall impact score. You can also explore how to reduce the climate impact of your portfolio.
No. Ziggma is brokerage-independent and does not execute trades. The optimizer gives you the analysis and simulated outcome — you place the trade through your own broker whenever you're ready. Learn how Ziggma connects to your accounts securely.
Portfolio tracking tells you what you own and how it's performing. Portfolio optimization helps you improve what you own — by simulating trades, identifying weaknesses, and finding better alternatives. Ziggma offers both, with the optimizer building directly on top of your tracked positions. Not sure where to start? Run a Portfolio Checkup first to get a full picture of where your portfolio stands today.
The Portfolio Optimizer is available on Ziggma's paid plans. A free tier is available for core portfolio tracking and basic analysis. See the full Ziggma pricing page for details on what's included at each plan level.
