Yesterday's negative gamma was concentrated in the 105k area, which overall means that volatility around this point is intensifying.

At the same time, today's gamma ex shows a leftward expansion, with negative gamma strengthening at the 100K and 102K positions.

Comparing the changes in positions over the past 24 hours, it can be seen that the main reason driving this change is that traders have bought a large number of put options at the 100k position, likely as a way to increase their bearish positions or to protect their contracts or spot positions.

Based on the current gamma data, it can be expected that there may be intensified fluctuations over the weekend, so it is necessary to take precautions to avoid excessive drawdowns.
