And if the price moves AGAINST them...... ?? Again, you can't move large amounts in and out of these markets. They're not US Treasuries or MBS with liquidity. JP Morgan Chase makes about $60 billion a year. They make a couple of hundred million trading precious metals each year. Do you honestly think they are going to increase the risk and capital to PMs to have higher volatility in earnings and a LOWER STOCK PRICE because of earnings volatility leading to a lower P/E ratio ? Do you see any sell-side analyst saying "JPM needs to engage in volatile trading so they can get a lower P/E which is already at a 30% discount to the S&P 500" ???
