Pure Storage (PSTG)
Oracle is getting out of hardware business. They have stopped investing in SPARC and they will only sustain support and most of their hardware will be engineered systems and supporting cloud. So I am not sure they have any use for Pure. Same goes for IBM.
Alteryx (AYX)
The marketcap will not allow HDP or CLDR take out. In fact, I was expecting HDP will be taken out but so far it had not happened and the price has more than doubled in the meantime.
Okta (OKTA)
I missed this one is a bummer. The stock price are rallying so hard, it is making it difficult to chase. What I heard is the management is not interested in selling. They got few serious offers pre-ipo.
