The prices at TASE are in 1/100 of NIS.
i.e. the TASE price is actually 61.21 NIS.
When you divide that by the USD rate to NIS, is get the US OPK price.
e.g. dividing 61.21 by 3.8 (The USD rate to NIS) you get $16.11
Would you all say that because NYSE trades on Monday, that it also trades on (say) Labor day, or Memorial day,etc.?
Same on TASE. NORMALLY, TASE TRADES on Sundays, BUT TODAY was a special day, whereby TASE was closed.
I don't know where people got their info.
