Short selling and short-selling constraints appear on 56 recent papers, but only 10 of them carry a China keyword, although China restricted securities lending repeatedly in 2023 and 2024 to support prices. What did the restrictions do to price efficiency, liquidity and the overvaluation of hard-to-short stocks?
The VIX and market liquidity are rising keywords in the finance journals, while options that expire on the day they trade have become a large share of US index options volume. Yet none of the 192 recent option and VIX papers carries a zero-day or 0DTE keyword. Do same-day options make intraday markets calmer or more fragile?

Treasury yields and bonds appear on 39 recent papers in the finance and economics journals, but only 2 of them carry a liquidity, dealer, hedge-fund or market-functioning keyword. Hedge funds' leveraged basis trades and dealers' balance sheet limits have been blamed for Treasury market stress. How fragile is the market now, and would central clearing help?

Mamba and other selective state-space models are among the most frequent new architectures in the AI journals, built for long sequences. Limit order books produce exactly such sequences. Yet only 4 of 329 recent Mamba and state-space papers carry a finance keyword, all of them in AI journals. Can these models forecast short-term price moves better, and is the gain tradable after costs?

Price impact and fund flows are among the fastest-growing keywords in the finance journals, yet none of the price-impact papers carries a fund-flow or passive-investing keyword. Now that passive funds hold so much of the market, how much do their flows move prices, and are markets as inelastic as some theories claim?

Market manipulation, stock market manipulation, price manipulation and pump-and-dump schemes appear on about 20 recent papers, split between the AI and finance journals. Spoofing, wash trading and coordinated pumps now happen in milliseconds and across venues, including crypto. Can detectors trained on known cases find new ones, and what do regulators miss?
Retail investors are a large topic in the finance journals, but only 8 of 139 recent papers on them carry a social-media keyword, and "finfluencers" appears on just 2. Do the trades that follow a finance influencer's post earn anything, and who profits from the audience?

Corporate bonds appear on 54 recent papers in the finance and economics journals, but only 7 of them carry an ETF, fund or liquidity keyword. Exchange-traded funds now hold a large share of corporate bonds and trade far more than the bonds themselves. Do they add liquidity, or hide the lack of it until a stress?

In the finance journals both "artificial intelligence" and "price discovery" gained papers this year, but rarely in the same paper. Do markets with more AI-assisted trading take in news faster, or just louder?
