Stock I did not trade in suddenly shows in my portfolio with big losses

Stock I did not trade in suddenly showed in my portfolio with a big loss.
There is not history record of me buying this stock, it just showed this morning in my account.

My trades are done using a software, with a fix set of symbols. the stock that appeared on my account is not one of those being traded, or was it ever in that list.

I looked at the “Orders” tab in my account, there is no record of me ever buying this stock.

how to contact Alpaca about this ?

This is the result of a cash and stock merger of ZNGA with TTWO

Hi @youdar,

Sorry about your experience. Sometimes, symbols are renamed for one reason or the other.
In your case, I presume that was what happened.

If you can let me know the symbol in question, as well as your email address/account ID, I could help you troubleshoot.

An easy way to contact Alpaca is by sending an email to support@alpaca.markets or joining our slack community.

Hi,
Yes, the issue was that the ZNGA stock was acquired by Take-Two, and it took time for the payment that was a part of this acquisition process to get into my account, so I suddenly saw a stock I did not buy, and the value of the account value suddenly dropped. A little alarming…
Thank you for following up
