Portfolio123 is a quant-grade research platform for people who want to build screening rules, rank stocks, and run portfolio-style simulations with realism. If you’re serious about testing dividend capture rules (entries, exits, hold windows, and risk controls), this is one of the strongest “proof engines” out there — but it rewards patience and punishes laziness.

Quick Summary

What Is Portfolio123?

Portfolio123 is a web platform built for systematic investing and quant research. You can create screens (filters), build ranking systems (score-based selection), and run portfolio simulations that model how a strategy might behave over time.

In plain language: it’s a strategy laboratory. You define rules, the platform tests those rules, and you learn whether your strategy is sturdy… or made of cardboard.

What It’s Good At

• Screening with precision: build rule-based filters to narrow down candidates fast.
• Ranking systems: score and sort your universe so the “best” candidates rise to the top by your rules.
• Portfolio simulations: test strategies in a portfolio context, not just one ticker at a time.
• Repeatable research: once your framework exists, testing variants becomes much faster and less chaotic.
• Reality checks: forces you to define exits, rebalancing behavior, and constraints instead of hand-waving them.

How Yield Raiders Use It

Dividend capture looks easy until you do it repeatedly and discover the hidden villains: bad entries, dumb exits, gap risk, and “I changed the rules mid-trade.” Portfolio123 helps you test and harden your system.

• Filter the candidates: use screens to avoid low-quality names that love to drop harder than the dividend pays.
• Test hold windows: compare exit timing rules and see which ones survive ugly periods.
• Stress-test exits: validate stops, time-based exits, and recovery exits so you’re not improvising under pressure.
• Model the “many trades” reality: portfolio simulations help reveal what happens when signals compete for capital.

“Portfolio123 is where dividend capture strategies go to earn their badge — or get kicked out of the squad.”

Watch-outs

• Learning curve: powerful systems require setup and thoughtful rule design.
• Not a dividend calendar: you’ll still want a dedicated source for ex-div dates and payout schedules.
• Not trade execution: Portfolio123 is research and testing, not a brokerage order ticket.
• Overfitting temptation: the more knobs you tweak, the easier it is to build a “perfect past” that fails in the future.

Pricing & Access Info

• Pricing: Check site for up-to-date pricing.
• Login Required? Yes
• Upsells or Ads? Expect plan tiers; advanced research, data, and higher usage limits are typically gated by plan.

Verdict: If you want to build a rules-based dividend capture process that’s tested and consistent, Portfolio123 is a heavyweight option — best for serious “prove it” investors.
