No, they're not accurate because they're 3x leverage (one bull, one bear) and they reset everyday after the percentage move.
Dangerous to play this if you're on the wrong side.

No, there are some tracking errors on those ETFs. The longer the timeframe, the more tracking errors and also they decay over time too - eventho if the underlying index stays the same over a longer time.

For example.

Let say if SP500 @ 2000 on day 1, SPXS=20
Within a month, SP500 may go up or down and let say it goes back to 2000 after 30 days,
you will find SPXS will be less than $20.
On other news...  did you see that 17% interest rate by Russia Central bank? This is absolutely insane!
I guess they got no choice because everyone in Russia now panicking and selling the Rubles like Zimbabwe currency.

closed all @55 shorts. all the way from $69

Thanks for heads up.. somehow it seems to be less attractive here. Will wait to see if 185 can hold or not.

On other tech stocks:  AAPL vs BABA. Almost back to old price of low 100'ish.

Which one do you guys want to do play? 

For leverage play, ERX (bull 3x), ERY (bear 3x).
Be very careful with either one of those two. They can be deadly (if you're wrong) or treasure chest (if you're right). 

Auntie Yellen is really powerful. She didn't really have to say anything or change any policy. Her appearance alone scared all the bears and make the bulls happy. 

.. perhaps everytime you buy/sell locally, they will charge you transaction fee, and currency exchange fee too.  That would be a double ouch.

$30/trade.. that's high.    Does this involve a human remisier assisted trade?

$30 could mean 30 trades for me..

The only fund that I am managing are my own family ones... 

Btw, watch your stop for XLE tonight... better not drop below 79. It seems the big money are taking profits for Christmas
after 5 good days of bull run.

existing holdings, think good chance as us economy looks strong, usd getting stronger.
crude... should see bottom "soon".
but... how to buy more with rm? now...3.5145.

i will probably look for good buys when rm rebounds a bit becos it will probably not last.

biggest winner today is aapl. 50% sales incr in 2014... mindboggling...

with that, etf's like spy, qqq weighted wih aapl all gain nicely.
5 days down, 2 days flat, 2 day up - still got a couple more days to run up!
