FlowHFT: Flow Policy Induced Optimal High-Frequency Trading under Diverse Market Conditions
High-frequency trading (HFT) is an investing strategy that continuously monitors market states and places bid and ask orders at millisecond speeds.

Why is the volatility of single stocks so much rougher than that of the S&P500?
The Nested factor model was introduced by Chicheportiche et al. to represent non-linear correlations between stocks. Stock returns are explained by a standard factor model, but the (log)-volatilities of factors and residuals are themselves decomposed into factor modes, with a common dominant volatility mode affecting both market and sector factors but also residuals. Here, we consider the case of a single factor where the only dominant log-volatility mode is rough, with a Hurst exponent $H \sim…

"But Wall Street professionals, like so many other ostensibly smart people, refused to see Trump clearly, mistaking his skill as a demagogue for wisdom as a policymaker. “I don’t think this was foreseeable,” a mournful Ackman posted on X on Monday. “I assumed economic rationality would be paramount.” What an odd assumption to make about a man who bankrupted casinos.
Berezin thinks Wall Street still hasn’t come to terms with the cost of the nascent Trump presidency. “I do think that at this point we might have passed the event horizon, meaning that even if Trump backs off from the tariffs, there’s been enough damage done to the U.S. economy, to the global economy, to investor confidence, consumer confidence, that we’re probably going to see a recession regardless of what happens,” he said.""

This is a dangerous level of squinting at tea leaves, so •serious• grain of salt here, but:
The sudden re-plunge of Tesla’s stock price during this Musk / Trump spat suggests that maybe, maybe its utterly wild overvaluation had nothing to do with Tesla’s products, or its market position, or Musk’s phony brilliance, or even (the usual explanation) with investors getting hyped about a self-driving car future and magical robots.
Maybe it was investors expecting the company to be the beneficiary of kleptocratic pillaging of the US Federal budget. Which — unlike all the other explanations — would not be an irrational expectation.

Read "What went wrong with capitalism" by Ruchir Sharma.
A mildly interesting description of the major events in world an US economics in the last 50 years. Might
be a fair summary for anyone who didn't live through it or has a poor memory.
In short he thinks what went wrong was government bailing out failure leading to massive debts and increa
sed inequality.
Governments took over all the things instead of letting capitalism sort them out, he reckons, and wheneve
r a big industry or company fails you just get socialism for the rich and a bail-out from new printed money.
Easy cheap money, constant bail-outs, government intervention, leading to zombie companies racking up every larger debt to exist, billionaires who can't fail due to government support, and a stock market that's up-only bringing a flood of inefficiently-allocated capital.
Is he right? I mean, maybe, sort of. But when an industry really can't be allowed to fail, say water supply and waterway management, allowing private capital to extract maximum resources from it isn't the best method to manage it in the first place. No wonder they need bail-outs. Capitalism fails here because capitalism isn't the right solution here. We need publicly owned national services, not robber barons without
bailouts.
So, you know, half right. Perhaps these are some of the reasons why capitalism fails, but also we shouldn't even be trying to apply capitalism to every single thing in the first place.

I know some of the money is thinking what @… says here. The trouble here is that Tesla is currently wildly, absurdly, comically overvalued wrt its fundamentals, and there are really only two rationalizations for that:
(1) Musk is a brain genius who will innovate the company into magic unicorn fairyland of world domination.
(2) Musk has Trump on a leash and will reap the benefits of kleptocratic plundering of the US Federal budget.
Both of those justifications depend on Musk remaining at Tesla. If he leaves, there’s little reason for the P/E ratio not to correct to normal car company levels — which AIUI would mean a stock price drop of >90%.

AI and the Dynamic Supply of Training Data
Artificial intelligence (AI) systems rely heavily on human-generated data, yet the people behind that data are often overlooked. Human behavior can play a major role in AI training datasets, be it in limiting access to existing works or in deciding which types of new works to create or whether to create any at all. We examine creators' behavioral change when their works become training data for commercial AI. Specifically, we focus on contributors on Unsplash, a popular stock image platform wit…

An Efficient deep learning model to Predict Stock Price Movement Based on Limit Order Book
In high-frequency trading (HFT), leveraging limit order books (LOB) to model stock price movements is crucial for achieving profitable outcomes. However, this task is challenging due to the high-dimensional and volatile nature of the original data. Even recent deep learning models often struggle to capture price movement patterns effectively, particularly without well-designed features. We observed that raw LOB data exhibits inherent symmetry between the ask and bid sides, and the bid-ask diffe…

One of the most important lessons I've learned in life / continue to learn / managed to forget is the importance of "stopping."

"Life is a very simple thing. We make it more complex." - Anonymous
"When we are making our life more complex, that is precisely the time when we are totally incapable of seeing what we are doing. The more complex our lives are, the more we need to be present to them and, surprisingly, this is exactly the time when we are most distracted. When we are distracted, we tend to have poor judgment and make more mistakes . . . usually adding to the confusion . . . and so it goes."
"....We usually respond by trying to become even more controlling and, eventually (or immediately!), this just makes things worse."
"It's time to stop, take stock, take some deep breaths, rest, listen to others, and regroup...We may miss something. We may even miss something we think is important. That's okay. We're more important."
"Taking time to stop may be just what I need to move ahead."

Revisiting the Excess Volatility Puzzle Through the Lens of the Chiarella Model
We amend and extend the Chiarella model of financial markets to deal with arbitrary long-term value drifts in a consistent way. This allows us to improve upon existing calibration schemes, opening the possibility of calibrating individual monthly time series instead of classes of time series. The technique is employed on spot prices of four asset classes from ca. 1800 onward (stock indices, bonds, commodities, currencies). The so-called fundamental value is a direct output of the calibration, w…

Inventory record inaccuracy in grocery retailing: Impact of promotions and product perishability, and targeted effect of audits
We report the results of a study to identify and quantify drivers of inventory record inaccuracy (IRI) in a grocery retailing environment, a context where products are often subject to promotion activity and a substantial share of items are perishable. The analysis covers ~24,000 stock keeping units (SKUs) sold in 11 stores. We find that IRI is positively associated with average inventory level, restocking frequency, and whether the item is perishable, and negatively associated with promotional…

FlowHFT: Flow Policy Induced Optimal High-Frequency Trading under Diverse Market Conditions
High-frequency trading (HFT) is an investing strategy that continuously monitors market states and places bid and ask orders at millisecond speeds. Traditional HFT approaches fit models with historical data and assume that future market states follow similar patterns. This limits the effectiveness of any single model to the specific conditions it was trained for. Additionally, these models achieve optimal solutions only under specific market conditions, such as assumptions about stock price's s…

The Dynamic Persistence of Economic Shocks
We propose a novel framework for modeling time-varying persistence in economic time series, allowing for smoothly evolving heterogeneity in shock dynamics. We leverage localized regression techniques to flexibly identify changes in persistence over time, offering a data-driven alternative to traditional parametric models. We applied this methodology to U.S. inflation and stock market volatility data and found substantial persistence variations that align with key macroeconomic events and market…

Can LLM-based Financial Investing Strategies Outperform the Market in Long Run?
Large Language Models (LLMs) have recently been leveraged for asset pricing tasks and stock trading applications, enabling AI agents to generate investment decisions from unstructured financial data. However, most evaluations of LLM timing-based investing strategies are conducted on narrow timeframes and limited stock universes, overstating effectiveness due to survivorship and data-snooping biases. We critically assess their generalizability and robustness by proposing FINSABER, a backtesting …
