Yandex, Qiwi tumble as markets, ruble, oil all fall sharply

• The Nasdaq is down 3.2%, Russia's Micex Index closed down 4.3%, the tuble has fallen to 77.7 against the dollar, and WTI and Brent crude have each fallen over 5% to less than $30/barrel. Quite a few other things are lower today as well.
• All of it spells an ugly Friday for Russian search leader Yandex (YNDX -7.6%) and Russian online payments leader Qiwi (QIWI -10.6%). Qiwi has made new 52-week lows, while Yandex (though down sharply from its spring 2015 highs) is still more than $2 above a 52-week low of $9.94.
