From early March through last Friday, there were really only a few ways to make any profits in the S&P 500, and looking at which strategies have been working gives us a good sense for the character of this market. First, let’s take a look at price action over this period. SPX went basically nowhere: Fig. 1. S&P 500 Index, March 6 – April 18. Source: CBOE Now, trading strategies can be classified according to the source of their risks/returns, meaning…

Last week SPY-options implied volatility dropped by almost 15%, which, along with the share price climbing above the center of our risk curve, was a drain on both unrealized return and projected profit at expiration. However, following the strategy rules for managing volatility risk with our entry trades is paying off: at Friday’s close, the unrealized return on our February trades was up from the week before. In post-session options-trading, we were showing about a 3.8% unrealized return on total…

As our portfolio vega and (negative) gamma grow (the latter to a decreasing degree each day, because the short strikes are spread out far to either side of the current underlying price), so does theta—the profit we accrue from decay in the value of our short positions. Let’s look deeper into that statement: Calendar-spread vega (change in net value with respect to implied volatility) increases with time, accelerating into front-month expiration. Short-gamma positions—ones that lose value at an increasing…

It’s been another wild week, as the market tries to find a bottom amid one string of bad news after another. Through disciplined adherence to our strategy rules, though, we’ve managed to keep risk under control without sacrificing a great deal in terms of profit potential. On the other hand, our unrealized return is quite another matter. As of this writing, our August portfolio is showing a loss on total capital at risk in the 20% range. Model Portfolio return,…
