Here is one more in the cheap calendar "near arbitrage" type trades. Last time I was actually at a net credit, and this time I paid a penny plus commissions to get exposure to $OSUR. Ideally this stock moves to just below $5 by the June expiration and then once those calls expire, it explodes before the July expiration. To me, these are the type of convex small risk / huge potential that retail traders often either ignore or miss. It is hard to find $20K worth of notional value in biotech for a month by risking $50+commissions. This mispricing happened because a large order moved the June $5 calls today but July did not move much, so I sold the expensive options and bought the relatively cheap ones in July. It took some work to get a fill on the short leg, but even though 5 minutes passed, the stock was unchanged, so for the pedantic types saying I took a risk by legging into it - this is the only way to trade these since there is no way to get a fill as a spread at one penny.…
