The love-fest from Facebook's (FB) IPO extends into its second day, as Zynga (ZNGA +7.5%) shares add to yesterday's 17% jump. But the options market isn’t so sure the rally is sustainable, as ZNGA’s “fear gauge” - a reading of 30-day implied volatility - jumps to a new high of 120%. At the least, traders view the stock as one with lots of volatility in its future.
