Straddles

Since ATM options are actually pretty cheap, I’m looking to buy straddles in $TLT and $HYG, looking for big moves in either direction (or maybe both directions) on today’s announcement. Small positions, so not risking much. If they don’t pay off today they could tomorrow or Friday.
Looking at this week’s expiration, HYG 80 straddle and TLT 121-122.
