Key legal question
Whether the taxpayer's securities and options trading constituted self-employment income or private capital gains for direct federal tax 1997/98.
Extracted holding
The transactions constituted gainful self-employment, and the resulting gains had to be taxed under Art. 18 DBG.
Extracted reasoning
The volume, frequency, and systematic nature of 343 option transactions, the use of covered calls and put/call sales, and the reliance on securities as security showed an activity directed at profit and exceeding mere private asset management. The whole securities portfolio was treated as business assets because it was essential to carry out the trading activity.
