Short Delta, Short Vega Positions

Short Delta Short Vega positions present a unique difficulty for the premium seller. While they do allow downside directional exposure by way of the <a href="https://ontt.tv/2qfF4rY">Short Delta</a>, the presence of Short Vega usually muddies up the waters. This is because Short Vega positions are hurt by <a href="https://ontt.tv/UlWqP">expanding volatility</a>, and volatility tends to expand when prices are falling. Therefore, as we see with our position in Visa, in a falling market a Short Delta position might benefit from the drop in price, but the corresponding rise in implied volatility could drag down profits.
