What actually is DadFin?

DadFin is a weekly stock-picking engine for US and Canadian equities. Every Sunday it scores the listed universe, publishes five books of five names with weights, then shows what those picks did. You get the screener, the scores, the per-name research, and the public record on one site.

Is DadFin a Koyfin alternative?

No. Koyfin is a charting workstation you configure. DadFin is an engine that already issued a verdict and will show you whether that verdict made money. Use Koyfin to explore; use DadFin to keep score.

How does it compare to Bloomberg?

It does not replace a Bloomberg Terminal (~$2,665 per seat per month). Bloomberg covers every asset class. DadFin covers US and Canadian equities, publishes named picks, and keeps score — from $20 a month on introductory Investor pricing.

How is it different from Seeking Alpha?

Seeking Alpha is a publishing platform: many authors, many theses, quality varying by author. DadFin is one systematic engine, one methodology on every name, and one consolidated record. Nothing here is a contributor talking their own book.

The track record is negative right now. Why show it that way?

Because a record you only publish when it flatters you is marketing, not evidence. It is a young record. Annualised statistics stay suppressed until twelve independent observations exist. The current published figures are on the receipts board above — we do not swap this answer when the number turns green.

How current is the data?

The full engine run is weekly, published Sunday, and every page stamps which run it is reading. The Trader Score and the price tape are live intraday, refreshed about every fifteen minutes during the session, and labelled live so you cannot mix them up.

What is the eight-axis score?

Valuation, quality, growth, price action, risk, conviction, liquidity, and macro sensitivity — each versus the name’s own sector, not the whole market. An axis with no inputs renders as a hole, never a zero, so a data gap cannot look like a judgement.

Is this investment advice?

No. DadFin publishes quantitative research and a record of its own published picks. It is not personalised advice, it does not know your circumstances, and nothing on the site is a recommendation to buy or sell any security.

Do I need a card for the free week?

Yes for Investor and Trader — we take a card at signup so the week can start. You are not charged unless you stay past the free week. Cancel anytime before it ends and you pay nothing. The Letter is email only and stays $0.

What is the difference between Investor and Trader?

Investor is the Sunday desk: all five books, screener, Vault, portfolio scoring, The Wire. Trader is Investor plus the live Trading Floor, Opportunity Map, Gap/Day/Swing compare, and 15-minute Trader Score during the session.

What if I only want the email?

Trader Bots & Weekly Strategies Beat the S&P 500—Plus Next Week’s Picks

A 100% win rate against the benchmark this week as our weekly buckets and debut AI bots outperformed a falling market. Here are the receipts and our November 1st selections.

Dad Street · 2026-11-02 · 19 min read

The Sunday Gameplan · cohort of November 1, 2026 · engine 30.4 The S&P 500 dropped 1.82% on the session to 7,580. Our engine remains in an Expansion regime with 86% confidence. The live market read sits at 55 of 100, which we rate as constructive. Our paper trading bots hold $99,616 from a $100,000 start on October 26, 2026. That puts the paper pot ahead of the S&P 500, which fell to $99,143 over the same period. Subscribers should look at the Value book first, where Nexa Resources ($NEXA), HCA Healthcare ($HCA), and ACCO Brands ($ACCO) enter as new selections. 🧾 The receipt - Weekly Picks & AI Bots Our Weekly Strategies Book Inception Return since S&P 500 Alpha Best Worst ----------- ----------- ------------ ------- ----- ------------- ------------ Value 29-Mar-2026 7.3% 2.8% +4.6% $DELL +138.6% $SFD -31.8% Dividend 21-Jun-2026 1.8% 0% +1.8% $HRB +49.2% $SFD -30.2% Multipolar 21-Jun-2026 -3.7% 0% -3.7% $SM +45.2% $HWM -28.3% Small Cap 21-Jun-2026 3.3% 0% +3.3% $PAYS +88.2% $TSSI -49.4% AI Frontier 6-Sept-2026 -0.8% -1.3% +0.6% $GEN +32.5% $SIMO -25.6% Our Value book cohort from 2026-10-25 led the week with a +2.7% return against a -0.6% drop for the S&P 500. BioCryst Pharmaceuticals, trading as $BCRX, was the top performer in that group with a +10.7% gain. Adobe, trading as $ADBE, was the drag on that same cohort with a -5.2% loss. Our AI Frontier book cohort from 2026-10-25 also beat the market but carried our deepest individual loss. Pinterest, trading as $PINS, fell -13.3% in that group. --- Hank, Otto, and Dottie - Our Trader Bot Debut Our paper-trading bots finished their first week since the Monday launch down 0.38% to $99,616. That beats the S&P, which dropped 0.86% over the same period. Hank, our fast-trading bot, took a clean 10.3% loss on $GOOG after it hit his stop-loss. He did not complain. He simply bought $FTNT and $MOD instead. Otto is finding better luck with lunch. His position in $CMG is up 13.4% since he bought it, leading our open trades. He also added $RSI to his garden on Friday morning. Dottie remains entirely in cash because the VIX is too quiet for her contrarian style. Our engine shows how much these businesses differ under the hood. Otto's holding $MOS carries a high-quality Dad Score of 83.0, while Hank's trade $GLXY sits in the poor band at 5.9. The bots do not care about quality; they only care about the setup. More details on our advanced paper trading bots are at the bottom of this article. Our bots make all their trades out in the open on dadfin.com - no login or sign-up required. Because we like sharing the fun. Check out our landing page to follow live what our bots are paper-trading and how they feel about the day! --- 📊 The macro read Regime: Expansion · 86% confidence · DadFin's live read: 55 of 100 · CONSTRUCTIVE Our weekly regime call remains in Expansion with 86% confidence. Alongside this call, our live market read sits at 55 of 100, which keeps our outlook at constructive. This reading persists even after the S&P 500 dropped 1.82% on the session to close at 7,580. The engine continues to see stable underlying conditions beneath the daily noise. A shift in this outlook would require a deeper breakdown in our core indicators. The VIX rose 12.91% on the session to finish at 19.42. If volatility continues to climb and our live read drops below the constructive threshold, the engine will adjust its stance. For now, the data keeps us steady. --- 💎 Value — free Good businesses the market prices as ordinary. 5 names; weights 100.0%.
