Tesla Update. Two Key Lessons.

I took some profits in my Tesla ($TSLA) position yesterday for the first time in 7 years. Technically, this was my second time taking profits, but the last I rolled my profit into Solar City ($SCTY), which was acquired by Tesla a year later. Tesla’s share price was up over 50% on the week and (more…)

When does Twitter Stock become cheap?

I’m reading the book Sapiens: A Brief History of Humankind by Yuval Noah Harari. In a section on the Agricultural revolution, Harari reminds us that while farming allowed human populations to grow, the quality of life for the average farmer was worse than the average hunter-gatherer.

Trefis values Facebook (based on the limited pre-IPO information they have) at $74 Billion, based (more…)

Facebook IPO Best and Worst Case Scenarios

Facebook released their numbers in preparation for an IPO, showing 2011 revenue of $3.7 Billion and profits of $1 Billion. Speculation is the IPO will be valued as high as $100 Billion. This would be a P/E of 100. That’s high, but then P/E’s are not as significant an indicator for young companies with a lot (more…)

“Payback Time” Analysis for GOOG

Digital Textbooks Sales Projection

Via blog.xplana.com: Personally, I think this is a little conservative… though kids and professors on campuses would probably know more about how motivated professors are to switch to digital textbooks. What I do know is that no one likes spending $100 for a textbook and my professors were always empathetic to this. Obvious investment plays (more…)
