I generally prefer to trade in stocks and ETFs I have a long history in since I know how they 'move'. ETFS Physical Palladium (PALL) is a relatively new offering in the market and this was my first time owning the ETF. I will say the volatility surprised me - a move from $57 to $42 (-26%!) in a month is a bit over the top. But it shows me this is just another hedge fund dominated instrument... when risk is on you buy, when risk is off they abandon it. The same goes for almost the whole commodity space at this point. In fact this chart almost could be overlaid exactly on top of the S&P 500 - it is basically a correlation; hence it provides little value add. If I want to correlate to the S&P 500 I'll just buy the S&P 500.
I am going to look for something a bit less exciting even knowing if we 'melt up' this ETF will rock and roll. I am closing the last 0.7% exposure with a 3% loss now that it has rebounded quite a bit from lows.
