Is the market turning away from index triggered insurance linked securities due to more sidecars and cat bonds coming into the pic? According to Willis Towers Watson (WTW), seems the market is trending in a different direction and index triggered ILS are loosing popularity.

Am I interpreting this correctly?

Snipit from internet report - on Nov 1, 2019: "Concretely, starting in Q4, but with more effect in 2020, we expect growth in the more liquid forms of ILS. In addition, some investors are realigning their portfolios toward more risk remote investments. The turn toward seeing increasing relative value at the more remote end could potentially bode well for cat bonds within the more liquid ILS space. Sidecar interest has picked up as well; however, the extent to which this interest will translate into completed deals will depend very much on the specific opportunities presented to investors, as not all deals will meet investor criteria. In addition to the surface market dynamics, we have identified two other trends to watch, one subtle and one headline grabbing that may impact the near term."
