I've done my own test to see where the options expiration theory...

Please be careful when making assumptions relative to "open interest." OI more closely expresses opportunity cost than profit/loss. Current positions are far more motivating, and are not directly reflected by open interest. As you know, the option writer has a number of alternatives in order to cover. Influencers include: relative value of offsetting options, short-term rates, liquidity and valuation of the underlying, etc.

Arbitrage is also an important consideration. IMHO, the nice pop seen today was the result of a slight breather followed by arb unwinding. (If so, an AM rally could easily occur.) The question remains: is ASND in a short call/long put situation, or the opposite.

Chris, regarding open interest...

The data you've collected can be particularly meaningful when comparing *in-the-money* calls and puts. According to your chart,
itm calls = 11521, itm puts = 9574. For this reason, I've mentioned the possibility of an AM rally (visa-vis buy programs). However, ASND oi disparity is more or less noise.

Traders often apply similar reasoning to index options in order to divine market behavior near expiration.
