If you are holding a trading account with one of those stock brokers who are still using that outdated back office reporting platform, you will notice an unfamiliar jobbing p&l section on the yearly p&l reports.
The jobbing p&l section on your p&l reports shows details of all those intraday trades you have done in the equity segment.
Jobbing p&l report means daytrading / intraday trading p&l report.
They could have made it less confusing and named it the Intraday p&l section instead, but back in the days when these systems were initially designed, day trading was commonly known as jobbing ( running around on your foot at the trade floor of the exchange and shouting out loud your buy and sell orders ).
Also, you will find a short term p&l section on your p&l report, this section details the summary of all those multi day positional trades you have done in the equity segment.
For tax filing purposes, for the equity segment, the p&l figures on both the jobbing and short term reports are netted and reported as a Short Term Capital Gains or Loss.
