Kevin O'Leary's Calls Of The Day: Alibaba, Facebook

Kevin O'Leary on CNBC's "Halftime Report" discussed his calls of the day.

O'Leary says he bought more Apple Inc. AAPL, Facebook, Inc. FB and Alibaba Group Holding BABA. He says there's a "Jack Ma discount" on Alibaba and thinks Ant Group will IPO by end of year.

"Alibaba is up to 5% of my holdings at this point, work from anywhere is an important theme and Facebook ads is the number one spend in my smallcap companies due to high IRR," says O'Leary.
