The daily chart of the agricultural ETF shows a nearly parabolic rise over the last most. Prices have moved from ~24.25 to 28.75 -- a rise of about 18.5%. Also notice the very bullish nature of the underlying technical -- a rising MACD, strong money flow into the security and rise in all the short term ETFs. Prices are now clearly above the 200 day EMA.
On the weekly chart, we see the strength of the rise relative to the nearly 2-years gradual sell-off in the security. Prices have moved through all the Fibonacci retracement levels from the peak of mid-2012. Also note the MACD has plenty of room to run.
