I think you should learn about the stock market before giving your idiotic advice. MXF fund has not,and probably will not recover for a long time, from its high of around 65 bucks. Which was where it traded before the Mexican financial crisis around 1995.
PB is cheap at current levels. It looks like its ready to break out to 20 level. However it is still to early to tell.
Re my "idiotic" advice (which incidentally people used to pay me for b/c I was a registered investment adviser rep in my state before becoming a medical student): If you believe MXF, which is essentially a diversified bunch of mexican stocks, will perform poorly, it's foolhardy to be picking mexican/lat am stocks like PB b/c their performance will likely be correlated to the broad market to a large extent.
If you think MXF was ever at 65 then you can't read a chart. However, the fund has _doubled_ since Oct '98, it's at a dirt cheap price to book (around 1), it's at a dirt cheap price to sales (less than 1/3 that of the U.S. market), and it's trading at a huge discount (about 30%) to its net asset value.
But you probably don't know what any of that means, anyway; right?
