THE INTERNET IS THINKING
Earlier sources: Markets
Markets connect capital, goods, services, and labor. This region follows economic developments, public markets, venture capital, fintech, and commerce. Source attention does not constitute financial advice or forecast investment returns.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗249 classified signals in the fourteen-day window. Recent momentum: rising. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Show HN: Investment Bets – market bets at live prices, humans or AI ↗
I've long been an index-investing type of person, but last year I started making some side bets, especially in tech (some inspired by WSB). I was sharing them with friends and wanted to simplify that. This is how Investment Bets came about: you pick a ticker, a direction (long or short) and optionally a target date. The server fetches and records your entry price when you open the bet, and your exit price when you close it or reach the target dat…

Show HN: Games that test if you can beat randomness in the market. ↗
I have been building a trading system and kept falling in same traps: Backtest that looks great but fall apart, good track records but they turn out to be luck so I made 4 games about them : Noise hunt: search a price series for winning rule.then bet on whether its edge is real Real or Random : check if it a S&P 500 stock series or random noise. The Star Manager: Hire portfolio managers by their track records and then check their performance. Por…

The Efficient Frontier from a LASSO Solver ↗
In a recent paper, Schmelzer and Hastie argue that Markowitz's Critical Line Algorithm and the LASSO path trace the same curve. Here we use that identity to compute efficient frontiers with a stock LASSO solver, \texttt{lars\_path} from \texttt{scikit-learn}. It handles long--short portfolios under a leverage cap, fixed leverage with varying risk appetite, and the classical long-only, fully invested frontier. Called naively, the last path stops at the maximum-Sharpe portfolio. One shift of the response, by an amount computed in advance, lets a single call reach the minimum-variance portfolio.

A Spread-Gated Hawkes-Flocking Model for Best Bid and Ask Dynamics, with an Application to Limit Order Placement ↗
We study the joint dynamics of the best bid and ask prices with a spread-gated Hawkes-flocking model. The model tracks four types of best-quote movements: spread-narrowing movements are switched off when the spread is at its one-tick minimum, and a cross-side excitation term, whose activation depends on the prevailing spread, links the two sides of the book. We show that the process is non-explosive on every finite horizon, give an $O(N)$ recursive likelihood, and validate the maximum likelihood estimator by simulation. On real intraday limit order book data for two large-tick stocks, INTC and…

Industrial Waste Management for a Circular Economy: Critical Perspectives on Prevention, Recovery, Treatment, and Resource Valorization ↗
Industrial waste management is often framed as technology selection, although sustainability depends on prevention, material quality, residual fate, and the displacement of primary production. This purposive critical integrative review examines industrial wastewater, sludges, and solid production residues using 106 cited sources: 42 retained papers from an initial 47-paper full-text collection and 64 complementary sources. It does not claim systematic or exhaustive coverage. The synthesis compares prevention, industrial symbiosis, treatment and recovery through functional equivalence, represen…

The effect of trade capacity constraints on disaster impacts: extending the Multi-Regional Impact Assessment (MRIA) model ↗
Disasters often disrupt supply chains, leading to cascading effects across regions. Regions not directly hit by the disaster may attempt to compensate for the lost production, but their ability to do so is constrained by their available production capacity and the logistical constraints between regions. This study introduces a Multi-Regional Impact Assessment (MRIA) model to evaluate the economic impact of disasters, capturing post-disaster trade dynamics and logistical constraints. The model uses EU interregional Supply and Use tables from Eurostat and is implemented for case studies in the N…

Why Households Undermine Sustainable Housing Policies: A Behavioral Housing Finance Perspective ↗
Sustainability-oriented housing policies rely on financial incentives, green mortgage products, and energy-efficiency programs to achieve environmental and long-term social objectives. However, their effectiveness remains limited at the household level, raising questions about why these instruments underperform despite growing policy attention and institutional support. While previous research has examined household responses to sustainable housing measures and behavioral influences on housing decisions, less attention has been paid to how behavioral mechanisms interact with mortgage finance i…

Harnessing renewable energy sources for hydrogen production using artificial intelligence within a circular economy framework ↗
The alarming scale of devastation in our environment and the grim picture of the global fuel crisis has spurred the need for sustainable energy alternatives. The hydrogen production from renewable energy sources offers a promising solution to achieve a carbon–neutral energy future in line with UN sustainability development goals. This review explores various renewable energy options like solar, wind, geothermal, and biomass for clean hydrogen production, emphasizing their potential, efficiency, life cycle assessment, and recent technological advancements. It also investigates the applications…

How to assess evidence about Markets
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
