I can understand Cramer saying that in 2010 but in 2015. Give me a break.
Unfortunately, Munger told Musk the same thing (I don't recall Musk mentioning the year) but Musk was pretty saddened to hear Munger tell him at lunch the number of ways Tesla would fail.
Now, of course, Munger is a fan. I love Munger but even he got Tesla wrong (and maybe BYD).
I, personally, think they should sell BYD and buy Tesla, but that certainly won't happen.
Full disclosure, I haven't followed BYD, it may well prove to be successful, but I'm not impressed based on the little knowledge I have of it.
