Its tough being a value investor these days when so many promising companies are actually loss making and growing rapidly. How do you analyze a loss making enterprise with no end in sight ? So I wouldn't fool myself in believing I can predict the outcomes for these venture investments inside BABA.
But simplest way to look at it is take the core-ecommerce business(include CAINIAO,LAZADA,Aliexpress,TAOBAO,TMALL,1688,etc) and put a multiple on this.
Then do your best guess on market value of rest of the businesses. One way is to look at a similar competitor and see its valuation.
Lazada competes with Sea Ltd. which is valued at 130B USD.
Ele.me competes with Meituan which is valued at 215B USD.
Alipay is worth anywhere from 100-250USD depending on if they can get license to run as a financial company with capital and if they don't have to share the proprietary credit scoring data.
Cloud is another 50-100B with reasonable P/S figures.BABA cloud serves 80% of chinese corporates and unlike US where cloud services are becoming commodities, in China cloud providers have to first help businesses digitize data and then put it in cloud. Since the cloud services are more customized for each vertical its a much more sticky/moaty business vs american counterparts. So how much is such business worth in future ? I would guess a lot.
If you subtract the estimtated value of these investments from BABA's market cap Alibaba looks damn cheap. But you won't be able to come to the same conclusion via doing a DCF or putting a multiple on net income. Just like you won't be able to use PE ratios and justify valuations for Meituan or Sea Ltd.
So honestly a simple thought process for buying BABA for the core ecommerce assuming at some point you would be able to spinoff/sell Alipay/Ele.me/Lazada/Cloud Computing at market valuations. If tech bubble doesn't totally crash in the next 5-10 yrs these investments will only get more valuable over time. Although you may not see positive contribution to income statements from these businesses value is still being created(atleast for now) if you trust the comps.
