PinkLion announced today the launch of its Tool Hub, a public set of investment tools built to cover the most common research tasks for self-directed investors. The hub pulls together utilities for ETF research, stock correlation analysis, portfolio backtesting, retirement scenario planning, and portfolio review, with dedicated modules for ETF overlap comparisons and portfolio tracking.
The Tool Hub organizes tools around the workflows investors actually run, like comparing ETFs side-by-side, checking ETF overlap down at the holdings level, reviewing historical portfolio behavior through backtests, and monitoring positions with portfolio tracking. PinkLion said the goal is to make these steps easier by offering one public place to start.
The ETF overlap module shows where two ETFs hold the same underlying securities and estimates the amount of overlap using constituent weights. The output is meant to support holdings-level comparisons when you’re evaluating how distinct two funds really are.
The fund analyzer pulls commonly referenced fund characteristics, such as performance history, fees, holdings composition, and risk measures, into one research view for initial due diligence.
The stock correlation tool measures how closely assets have moved together historically and supports diversification checks. It provides correlation views and can show how relationships between assets change over time.
The portfolio backtesting tool evaluates how a portfolio allocation would have behaved across historical periods and provides comparable return and risk measures for review, including drawdowns and period-based performance.
The Monte Carlo retirement tool models a range of possible retirement outcomes across different market paths and highlights how sequence-of-returns risk can impact sustainability. Results are shown as distributions and summary probabilities, not a single-point forecast.
The launch follows continued growth in ETF usage and sustained retail participation in U.S. markets. The Investment Company Institute (ICI) reported that total U.S. ETF assets were $13.37 trillion in December 2025, and a separate ICI release noted ETF assets increased $3.07 trillion (29.8%) over the prior 12 months. ICI also reported that the combined assets of U.S. indexed mutual funds and ETFs rose to $19.26 trillion in December 2025. Reuters reported that retail inflows into U.S. stocks reached a record in 2025 (citing J.P. Morgan analysis) and that retail trading accounted for roughly 20%-25% of activity during the year, peaking higher during periods of market volatility.
“Many investors use multiple tools across fund selection, diversification checks, and retirement planning, but results can be hard to compare when inputs and assumptions are scattered across multiple places,” said a PinkLion spokesperson. “The Hub groups commonly used research steps in one place and keeps the inputs visible so analyses can be repeated and reviewed consistently.”
PinkLion stated that the Tool Hub is designed to support research steps often performed before and after investment decisions, including comparing ETFs, reviewing overlapping holdings across funds, evaluating diversification and co-movement through correlation, and testing portfolio behavior across historical periods through backtests.
