 ## New data relative to the October 2025 release
 
-- Data through December 2025
-- *Exceptions*:
-  - Predictors based on OptionMetrics implied vol (CPVolSpread, dCPVolSpread, dVolCall, dVolPut, RIVolSpread, skew1, SmileSlope) are still taken from [our August 2023 release](https://drive.google.com/drive/folders/1EP6oEabyZRamveGNyzYU0u6qJ-N43Qfq) and end in December 2022
-    - OptionMetrics [revised their methodologies](https://optionmetrics.com/news/optionmetrics-releases-ivydb-us-6-0-and-ivydb-etf-4-0-with-proprietary-methodologies-for-faster-more-precise-options-implied-volatilities/) in March 2024, which caused large revisions to option-based predictors. See [issue #156](https://github.com/OpenSourceAP/CrossSection/issues/156)
-  - Predictors based on the Gompers, Ishii, Metrick governance index (Activism1, Activism2, and Governance) end in 2007 as that data is no longer updated
-  - ProbInformedTrading relies on the Duarte et al. data which ends in 2012. See [issue #171](https://github.com/OpenSourceAP/CrossSection/issues/171)
+- Data through December 2025, with the following *Exceptions*:
+    - Predictors based on OptionMetrics implied vol (CPVolSpread, dCPVolSpread, dVolCall, dVolPut, RIVolSpread, skew1, SmileSlope) are still taken from [our August 2023 release](https://drive.google.com/drive/folders/1EP6oEabyZRamveGNyzYU0u6qJ-N43Qfq) and end in December 2022

See [issue #156](https://github.com/OpenSourceAP/CrossSection/issues/156)
+    - Predictors based on the Gompers, Ishii, Metrick governance index (Activism1, Activism2, and Governance) end in 2007 as that data is no longer updated
+    - PatentsRD uses NBER patent data that ended in 2006. 
+    - ProbInformedTrading relies on the Duarte et al. data which ends in 2012. See [issue #171](https://github.com/OpenSourceAP/CrossSection/issues/171)
 - CRSP data now comes from CRSP v2 (CIZ format) instead of the legacy SIZ format, which WRDS is retiring
-  - Applies to both the signal and portfolio code. The portfolio code no longer downloads CRSP itself; it reuses the CRSP files downloaded by the signal code
-  - Differences between v1 and v2 outputs, and how we handled them, are documented in [Docs/CRSP-v2-Migration.md](https://github.com/OpenSourceAP/CrossSection/blob/master/Docs/CRSP-v2-Migration.md)
-  - The switch moves portfolio returns little. Rebuilding the 26 signals listed below (R-sq < 95%) on legacy CRSP returns changes their R-sq against the previous release by less than one percentage point. Most of the effect of the switch runs through the signals instead, mainly through SIC and exchange codes (see below)
-- Size, Price, and STreversal (still excluded from the downloads) can now be built from CRSP alone with `Signals/pyCode/crsp_only.py`. `12_CreateCRSPPredictors.R` has been removed
-- Code is now Python (signals) and R (portfolios) only; the placebo translation is finished and no Stata is needed
+    - Differences between v1 and v2 outputs, and how we handled them, are documented in [Docs/CRSP-v2-Migration.md](https://github.com/OpenSourceAP/CrossSection/blob/master/Docs/CRSP-v2-Migration.md)
+    - The switch moves portfolio returns little. The R-sq from regressing this release's long-short returns on the previous release leads to an R-sq > 98% for 75% of predictors. 
+
+## Data format update
+
 - Files are now parquet instead of zipped csvs, and each set of signals or portfolios is one file. See Directory below
+- The redundant individual signals and individual portfolios are no longer posted.
+- These changes were made as part of a migration from Google Drive to Hugging Face
+    - Google Drive could not handle the volume from the download packages (https://github.com/OpenSourceAP/CrossSection/issues/228)
 
 ## Signals with Non-Trivial Revisions
 
 Non-trivial revisions means R-sq < 95% from regressing this vintage's monthly long-short returns on the previous vintage's (full sample). 26 of 212 predictors qualify. R-sq in parentheses.
 
 - Traceable to issue fixes
-  - PayoutYield (48.6), NetPayoutYield (78.5): fix preferred stock handling (`pstkrv` is a stock, not a flow) and improve replication
-    - See [issue #207](https://github.com/OpenSourceAP/CrossSection/issues/207), thanks to SeongDeok Ko
-  - CompositeDebtIssuance (79.4): drop infinite values from log(x/0), and match debt 60 months earlier with a proper calendar lag instead of a positional shift
-    - See [issue #219](https://github.com/OpenSourceAP/CrossSection/issues/219)
-  - Other signals using calendar lags: standardized so missing months are not filled with the wrong observation, and months inserted to compute lags are no longer kept in the output. Signals that moved: CitationsRD (59.1), MomOffSeason11YrPlus (88.4), MomOffSeason16YrPlus (91.2), MomOffSeason06YrPlus (92.4)
-    - See [issue #219](https://github.com/OpenSourceAP/CrossSection/issues/219)
-  - IntanEP (78.8), IntanSP (80.5), IntanCFP (82.8): follow the original paper by taking logs of all ratios and using income before extraordinary items (`ib`) instead of net income throughout
-  - High52: split-adjust prices, and include the current month in the 52-week high, following George and Hwang (2004)
-  - Market equity at the permco level: applied more carefully, so permco-level market equity is used only to scale accounting variables
-    - See [issue #167](https://github.com/OpenSourceAP/CrossSection/issues/167)
-  - Placebos: about 10 placebo scripts now follow the original Stata code more closely

+    - Placebos: about 10 placebo scripts now follow the original Stata code more closely
 - Traceable to the CRSP v2 migration
-  - SIC codes: from about 2008 the legacy CRSP tape stopped classifying new listings (SIC 9999). CRSP v2 classifies them, which changes industry membership. Affects EarnSupBig (77.0), Herf (77.9), HerfAsset (82.8), HerfBE (84.0), MS (89.4), OrgCap (89.6), ChInvIA (89.7), IndMom (91.7), sinAlgo (92.7), and IndRetBig (94.7)
-  - ExchSwitch (81.7): CRSP v2 assigns exchange codes to about 21,500 stock-months that the legacy data left unclassified
+    - SIC codes: from about 2008 the legacy CRSP data left many new listings unclassified (SIC 9999). Apparently CRSP v2 did not classify these listings either as of July 2024 (Schwarz, Walter and Weiss find almost no SIC differences between v1 and v2 in data from that time). As of October 2026, CRSP v2 assigns them codes, which changes industry membership. Affects EarnSupBig (77.0), Herf (77.9), HerfAsset (82.8), HerfBE (84.0), MS (89.4), OrgCap (89.6), ChInvIA (89.7), IndMom (91.7), sinAlgo (92.7), and IndRetBig (94.7)

+    - ExchSwitch (81.7): CRSP v2 assigns exchange codes to about 21,500 stock-months that the legacy data left unclassified
 - Traceable to data revisions
-  - ChangeInRecommendation (93.6), UpRecomm (93.7), ConsRecomm (93.9), DownRecomm (94.5): IBES has removed or revised some historical analyst recommendations. Values are unchanged where both vintages have data
-  - Investment (93.0): firm-months with zero capital expenditures throughout the 36-month averaging window are now missing (0/0). The previous release recorded them as zero due to floating-point rounding in the rolling mean
+    - ChangeInRecommendation (93.6), UpRecomm (93.7), ConsRecomm (93.9), DownRecomm (94.5): IBES has removed or revised some historical analyst recommendations. Values are unchanged where both vintages have data
+- Traceable to floating-point precision
+    - Investment (93.0): firm-months with zero capital expenditures throughout the 36-month averaging window are now mostly missing (0/0), matching the Stata original. The previous release recorded about 8,800 of them as zero because of floating-point residue in the rolling mean, which still affects about 200 firm-months in this release

-The drop in early 2023 is mainly due to our decision not to update OptionMetrics predictors due to inconsistencies between data vintages: their signals end in December 2022, so their returns end in January 2023. The drop in late 2025 is due to PriceDelaySlope, PriceDelayRsq, and PriceDelayTstat, whose returns end in August 2025 (the signals are estimated each June and last updated in July 2025), and to OptionVolume1 and OptionVolume2, whose OptionMetrics volume data on WRDS ends in August 2025, so their returns end in September 2025.

+    - Unless noted, portfolio files are long, with columns: signalname, port, date, ret, signallag, Nlong, Nshort. `port` is the portfolio name (01, 02, ..., LS for long-short), `ret` is the monthly return in percent during the month indicated by date, and `signallag` is the portfolio's average lagged signal

+        - Full sets of portfolios following the original papers (OP)
+        - PredictorPortsFull.parquet
+            - Portfolios formed on each predictor (e.g. 5 portfolios formed by sorting on momentum), plus the long-short portfolio
+            - Includes what some people call "test asset returns." Can also be used to study monotonicity
+            - Implementations based on the original papers. See SignalDoc.csv
+        - PredictorLSretWide.parquet
+            - Long-short returns only, in wide format. Columns: date, then one column per predictor

+            - Like PredictorPortsFull, but only continuous predictors, and implemented as deciles. Stock weights follow OP
+        - PredictorAltPorts_DecilesEW.parquet and PredictorAltPorts_DecilesVW.parquet
+            - Like PredictorAltPorts_Deciles, but stock weights are all EW or all VW
+        - PredictorAltPorts_Quintiles.parquet, PredictorAltPorts_QuintilesEW.parquet, and PredictorAltPorts_QuintilesVW.parquet
+            - Same as the decile files but with quintile sorts
+        - PredictorAltPorts_FF93style.parquet
+            - Like PredictorPortsFull, but uses Fama-French 1993 style 2x3 sorts
+        - PredictorAltPorts_HoldPer_1.parquet, \_3, \_6, and \_12
+            - Like PredictorPortsFull, but uses "rebalancing periods" of 1, 3, 6, and 12 months instead of the original rebalancing periods
+            - These rebalancing periods should really be called signal updating periods, since value-weighting or equal-weighting is always enforced monthly, see footnote in the paper
+        - PredictorAltPorts_LiqScreen_ME_gt_NYSE20pct.parquet, \_NYSEonly, \_Price_gt_5, and \_VWforce
+            - Like PredictorPortsFull, but with various liquidity adjustments. Please see paper
