I'll try to update this thread as we apply corrections to Wealth-Data. Currently, you'll need to refresh the charts for each symbol to get the corrected data. Later in Build 33+, we'll implement options for automatic refreshes / corrections.

CD.X = Special Dividend
CD.R = Regular Dividend (no adjustment for these)

CODE:
Symbol   Ex-Date      Adj. Factor   Description IBM      2021-11-04   1.0469406   Spinoff Kyndryl (KD) ROL      2021-11-09   1.0022428   CD.X $0.08 (CD.R will be $0.10)

Example:
You can see that if you had owned IBM on 11/3/2021, your backtest will have realized a loss the next day due to the spinoff. In the real world, you'd get cash or shares for the spun company for the amount of that gap. Accounting for the gap using an adjustment simplifies the simulation, and, it doesn't result in feeding that "step" into indicators you might be using.



Incidentally, I was surprised to read that Kyndryl, about 4.7% of its parent IBM, is a $19 billion start-up with 90,000 employees! However, the market has already given KD a 25% haircut in its first 4 days :/

We noticed that settled Closing prices were incorrect for yesterday's session on 01 March 2022 for about 50 symbols. In most cases, they differed by only a penny or two, but some were more -

AAPL, Was: 163.38,  Is: 163.20
AMAT, Was: 129.79,  Is: 129.61
ATVI, Was: 81.125,  Is: 80.88
ISRG, Was: 291.86, Is: 291.55
GOOGL, Was: 2684.145,  Is: 2681.23

I'd recommend that you use the Data Manager to truncate Wealth-Data's S&P 500 and Nasdaq 100 DataSets after 28 Feb 2022, and then update (or just re-run your strategies).

On special dividends, we changed the previously-reported PXD $3.78 dividend on 2/25/2022 into 2 parts, $0.78 for the Regular Dividend, and a $3.00 Special Dividend. (https://investors.pxd.com/news-releases/news-release-details/pioneer-natural-resources-declares-first-quarter-dividend-common) This correction was just applied:

Most often, wild low volume trading occurred on non-NYSE exchanges during the first minute after which trading was halted. Later, trading re-opened on NYSE at the time indicated, which Wealth-Data uses as the opening print.

Hopefully they'll be fixed soon.

BTW, kudos for doing the data corrections, many other data providers haven't done it (and may never will). Symbol VZ was one of the most egregious examples... it made a 1-year High and a 1-yr Low on the same bar (before data correction)!! LOL

These were a result of errors in our constituents database that didn't properly change the symbols. TWTR doesn't exist, its data is TWTR.221027.P. RDS.A (and .B) is SHEL - https://investorplace.com/2022/02/shel-stock-in-focus-as-shell-waves-goodbye-to-royal-dutch-name-and-rds-a-rds-b-stocks/

This is fixed. Restart WealthLab to get the changes, which will have a minor effect on S&P 500 backtests with Wealth-Data.

VEON's scheduled 1:25 reverse split was applied (multiple times) yesterday, but it turns out that the action was postponed -

https://finance.yahoo.com/news/veon-announces-postponement-effectiveness-ratio-060000237.html

Check your VEON data and refresh the chart if the split was applied.

In any case, we're considering terminating the VEON series instead of doing the 1:25 reverse split (if it happens) so that the price level is maintained for the time it was in the N100 - better for backtesting.

VEON split confirmed for today -
https://finance.yahoo.com/news/veon-confirms-revised-timing-effectiveness-153000419.html

I was just looking at the timing of when VEON was added to the "Nasdaq 100 Trading System" - it was in Oct. 2013. Apparently, someone thought the chart pattern looked like a cup & handle. That was a mistake and VEON was removed about 2 years later.

If you have a strategy that filters by market price, make sure to use the SplitRev indicator for that rule!

Crane Holdings, Co., is spinning Crane Company, which retains the symbol, CR. The distribution appears to be $40.30, from a last closing price of 114.42, which makes for a split adjustment factor of 1.54128408.

https://finance.yahoo.com/news/crane-company-completes-separation-crane-210100518.html

As for Wealth-Data, I think later this wee we'll preserve the pre-split Crane Holdings, Co series as CR.20230403.R for backtesting purposes. The new CR will retain the history, post split.

The history for STCN has been restored following an issue processing the reverse split on 6/22/2023. Refresh your STCN charts from Wealth-Data now!

Nonetheless, since STCN really only interests us for the time it was in the Nasdaq 100 (1999-2000), we created a series STCN.20071031.S. This series ends on the 10/31/2007 and its prices are "reverse-adjusted" for the 2 large reverse splits (1:10 and 375:3500) and the 1.16111 special distribution on 3/15/2011. In other words, the prices do not include these "future splits" and are more "in range" of prices when STCN was actually trading in 2001.

After you restart WealthLab, STCN.20071031.S will replace STCN in the WealthLab Nasdaq 100 DataSet.
