Quote from 1st_samurai:
WEB bought in 97' around $4.50 and took delivery. He has some storage costs. To him an investment, but probably more a hedge against financial assets/securities.
WEB doesn't use a "stop loss" because he is a genius of high calibre that knows the value of what he's buying. Stop loss is for all shorts, and longs when you're not sure of the value you're buying.

Berkshire Loses on Bet Against the DollarQuote from CPTrader:
Do you include forex positions in SEC filings? Is forex under their purview? I thought SEC filings only relate to stocks and even then, you can delay disclosures under special circumstances with their approval.
I still think CNBC is guessing and/or reporting rumors.
