My sources tell me that AMZN's sales commission will be between 5% and 20%. I'm anticipating that the higher the price, the lower the commission as that's one of the most popular commission standards in the world of collectibles. Does this contribute to justifying AMZN's sky-high share price? At Friday's closing price of $305.23, shares are slightly more than $4 from the 52-week high. With a forward (one-year) PE ratio of 96, that's better than its current nonexistent PE since AMZN doesn't have any after Ebitda earnings (EPS) yet. Let the five-year price chart below speak for itself. I've included the trailing 12-month (TTM) revenue per share which shows remarkable results. This is about as pretty a chart as can be found. AMZN data by YCharts Now the question is, can AMZN keep on mastering the "art" of driving revenue up to the sky in order to support the current share price? It's interesting that the median estimated price target for AMZN among 36 analysts is about $325 per share. That same crew of analysts expect the quarter ending June 30 to show sales growth and an increase in revenue of nearly 23%. EPS could actually be an earth-shaking 6 cents per share. Gulp! It's ironic the high price of AMZN shares says that the Street expects big things to come in the coming quarters. Maybe that's why Amazon has to sell big-ticket items like fine art. Let's see, a 10% commission on $100 million worth of rare art would bring in $10 million. Maybe that's the tip of the iceberg or, as Picasso might have said, "The future value of my paintings is inestimable!" That could also be said for Amazon.com's share price. I, for one, won't bet again Jeff Bezos and company.
