Look what Haaretz is reporting:
Haaretz reports about massive short-selling of Israeli shares in the days before October 7, indicating that “somebody seemingly knew [of the attack] in advance and made billions betting against Israeli shares traded locally and on Wall Street”
Here’s the Haaretz headline:
Did Hamas Make Millions Betting Against Israeli Shares Before October 7 Massacre?
Giant gambles against Israel on the markets in Tel Aviv and Wall Street days before Hamas’ attack made billions. Somebody seems to have known about the plan in advance
Hamas’ attack on Israel on October 7 caught the Israeli army unprepared. But somebody seemingly knew in advance and made billions betting against Israeli shares traded locally and on Wall Street five days before the attack.
So, as they say, the IOF may have been caught unprepared, but somebody was prepared. Who? Hamas?
While the question remains valid, it might well be that the 'killing' has been exaggerated by 100 times.

Not only did "somebody" (actually a lot of bodies) have apparent prior knowledge of the attack they also apparently knew the attack would be successful. After all, a failed incursion across the border resulting in a few Hamas deaths (and without the subsequent massive Israeli response in Gaza) would not have had a great impact on the Israeli economy or on Israeli stocks. So how does that extent of prior knowledge narrow down the field of suspects? It would certainly be illuminating to know who was making those trades on behalf of whom.
