Into MS Mar 16 '13 $23 Calls @ $0.42 + Into MS Mar 16 '13 $23 Puts @ $0.25...

I used a ratio of 1 call for every 2 puts on this trade, essentially investing 50% of allocated capital in each direction.

US banks are expected to announce dividend increases, share buybacks, and other return of capital to shareholder measures this week, so there should be plenty of price volatility following these announcements.  

I thought about doing another DIA trade, but in comparison, MS calls and puts are a lot less expensive.  Open interest in both calls and puts on the $23 strike price remains high, so the secondary market is active enough to ensure liquidity...  Don't want to be trading against the market makers!
