Alt-Data Sentiment at the Portfolio Level: Rolling Up the Signals
Monitoring WSB, news, insider filings, and options flow across 40 positions manually isn't realistic. A portfolio-level sentiment roll-up triages the 3 names that moved from the 37 that didn't.
Portfolio Attribution: Where Your Returns Actually Come From
Beating the benchmark by 400bps feels good until attribution tells you it was all allocation luck on one sector call. Selection vs. allocation vs. interaction is where skill separates from luck.
Portfolio Audit Trail: Every Decision, Timestamped and Queryable
Regulated managers need an audit trail. The Audit Trail card on alphactor.ai records every trade, rebalance, alert, and note into one timestamped log you can export.
Portfolio Credibility: Scoring Your Book Against an Evidence-Based Baseline
Conviction is self-reported; credibility is externally anchored. The two diverge exactly where mistakes live — an 8% position in a name you love with a credibility score of 35 is where alpha leaks out. Credibility scoring surfaces the gap before the drawdown proves it.
Portfolio Earnings: Calendar, Exposure, and Per-Position Risk Into Prints
Earnings risk is about the whole book into the week, not each position. When 40% of NAV reports in one week — and 60% of that is in a single sector — you're running concentrated event risk whether you sized each name correctly or not. The portfolio-level view is the one that changes decisions.
Factor Exposure on Your Portfolio: Value, Momentum, Quality, Size
Every portfolio has implicit factor exposures whether you wanted them or not. The Factor Analysis card on alphactor.ai decomposes your book into the six factors that explain most of its risk and return.
FX Exposure: The Currency Risk Hiding in Your USD Portfolio
You bought US stocks in dollars, so you have no FX risk, right? Wrong. US large-cap multinationals earn 40-60% of revenue abroad. When the dollar rallies 4% in a quarter, those earnings translate down — and your supposedly USD book loses 150 bps of attribution to an FX move you never thought you were taking.
LP Report: Institutional-Grade Portfolio Summaries, Automated
Reporting is the tax on managing other people's money. A good LP report system takes a 12-hour manual job and turns it into a 90-minute review-and-polish exercise, without sacrificing the quality LPs notice.
Portfolio Optimizer: From Holdings to an Efficient Frontier
Mean-variance is the most abused tool in quant finance. Naive outputs always overweight recent winners. Risk parity and Black-Litterman fix different parts of the problem; using all three and comparing is the discipline.
Portfolio Rebalance: Turning Drift Into Scheduled, Boring Trades
Portfolios rebalanced on a schedule beat portfolios rebalanced 'when it feels right.' Feel-right under-rebalances winners, over-rebalances losers, and stops entirely during drawdowns — when rebalancing adds the most value.
Transaction Cost Analysis: The Slippage You're Not Measuring Is Eating Your Alpha
Implicit execution costs — spread, impact, timing — routinely run 10-50bps per trade for retail books. At 2× turnover that's 40-200bps per year of negative drag on a portfolio strategy that may only target 500-800bps of alpha to start with. TCA makes the invisible visible.
Brinson Attribution: Did You Pick Good Stocks, or Just Good Sectors?
Outperformance has two ingredients: the sectors you chose and the stocks you picked inside them. Brinson-Fachler attribution separates the two — so you know which skill to keep.
