That's my grade from trading.
Seriously, keep your eyes on China (those are 30d30m charts)
Also, look at EUO (have you heard of it?)
beanie,
Name you time frame and I will bet you that SLX or MOO will outperform PBW.
3 years from now:
PBW from 25 to 100 (hell yeah!)
SLX from 88 to 350
MOO from 53 to 210
NLR from 39 to 155
Which is more likely? PBW, back up 9 trucks.
Btw, PBW is an etf. Nothin wrong with 50% of your money in it. Just watch the sector and watch the chart for developments.
