ARYMF is one of those foreign stocks trades in US markets, but...

ARYMF is one of those foreign stocks trades in US markets, but in the lowest regulated division of all US markets, called 'Pink Sheets'. On 'OTCMarkets' they said:
"Warning! This security is eligible for Unsolicited Quotes Only. This stock is not eligible for proprietary broker-dealer quotations. All quotes in this stock reflect unsolicited customer orders."

If you wish to follow US stocks on any exchange there, NYSE, AMEX, Nasdaq,
OTC etc., you can create your own portfolio 'Stocks I'm watching' with 'seekingalpha', which gives you daily quotes and news ( per mail) for every single stock you wish to view. This could also be helpful for ASX stocks with notification on US boards.

For example 3-mth chart of ARYMF with 'OTCMarkets'

As @ahboy said above 'US on low volume' you can see at 'seekeingalpha'
the volume on friday was 339,100 versus an average volume of 81,377 only.

So if volumes for these ASX stocks in the US are generally tiny compared to their home exchange, it might be worth noting in this case:
1. Volume on friday was much higher than average volume
2. Volume on friday was very much higher than those 'next to nothing volumes'
for ASX stocks in US
3. Wonder why we see point 1 and 2 on these US markets now !?

Maybe there is a bird In US telling those punters to take more notice of us
but don't be confused, this is just the humble opinion of a german shareholder,
trading australian stocks on ASX, you know!
