Can a HF manager do this?

[JackRab]

I think it definitely still happens...

For instance, at expiry... stocks (and also the index-level) can be pushed on a certain strike where there's large interest. There's a bit of manipulation going on there...

Listen,it's OK to be wrong,You must not be a good trader and probably stay in losing trades
too long,due to you not being able to admit you are wrong . Tsk tsk tsk not a good trait for trading.

You are now reprimanded ,go to your room until you learn your lesson. : )

PS: I have nothing against HF's ,but please,stop making excuses for the nefarious HF's,it's not a good look.

Said like a true Troll! tsktsk... I see your profile is limited as well... no need to say more... bye...

This is a different study, done by Finnish professors, and it also includes an advice for retail traders:

"Because the pattern is so ingrained, investors can profit with this recipe: Buy shares three days before the end of the month and sell them three days into the new month, he says."

"The patterns described in the paper aren’t a secret among fund managers, and some try to time fund purchases and sales to take advantage of it, including Source Morgan Stanley Europe MEMO Plus UCITS ETF."
