Trader takes a HUGE Bullish Bet in YELP and finds the bottom

Yelp Inc. operates as an online local guide that connects people primarily with boutiques, mechanics, restaurants, and dentists. Yesterday, we at www.keeneonthemarket.com saw a trader buy 9500 YELP May 75-90 Bull Call Spread for $2.60 debit. This is a HUGE bet that YELP will trade above $75 by May expiration. This was a $2.6 Million bet, so yesterday I bought the May 75 Calls for $3.20 and I am up over $7,000 in 2 days and I think that YELP has more upside potential.

The Trade: I bought the YELP May 75 Calls for $3.40
Risk: $340 per 1 lot
Reward: Unlimited
Targets: $3.80, $4.40, $5.00, and $5.50
