WDC-WESTERN DIGITAL CORPORATION-This stock has been performing terribly.  Down 57.5% on the year.  Currently selling at 42.73.  All sorts of rumors going around about patents they bought from IBM and on their buyout of sandisk.  P/E is now 7.96.  Cap is now at 10.37.  Short interest is now at 5.07%.  Dividend is at 2, so 15 with tax and ten.  PEG ratio is high indicating poor future growth prospects.  Analysts are bullish.  Book is at 40.42.  Average p/e is at 11.95.  Earnings are expected to be great this year but only up 2% over the next 3-5 year over year.  Book is growing at 14.38.  Return on equity is at 14.38.  Debt is at 23.65.  Looks like they have an earnings call on 1/28/16.  Their earnings are pretty good but imperfect.  Earnings have compounded at 12.45%.  Dividends are pretty steady.  Insider ownership is at 6.2.  We’ll say EPS is 5.36 and thus the dividend is about 40% of EPS.  Book grows at an amazing rate we’re talking about 22.71%.  The average and mean return on equity is gonna be high, but we can use the current rate…conservatively.  So if we use their compounded book growth rate, we could see book value of 149.85, and thus EPS of 20.979 and thus a price of 166.99 using the current p/e and 250.699 plus 15 in dividends for a value of between 20.05 on the high end and 15.59 on the low end.  Let’s say we look at their earnings of 5.36 and continue the compounding at 12.45, we could see EPS of 17.33, and with p/e of 7.96 v. 11.95, we could see share prices of 137.95 v. 207.09 plus the 15 in dividends for respective values of 152.95 v. 222.09 and thus rates of return between 13.6 and 17.92.  Let’s look at it as if return on equity is at 14.38 (which is very low) and they keep 60% to grow the business, we could see a book growth figure of 8.628 and thus book value of 92.49, and thus EPS of 12.948 and thus using our p/e figures a price of 103.07 or 154.728 plus the 15 for values of 118.07 and 169.728 and thus rate of return of 10.70 on the conservative low v.  14.79 on the higher side.  The company looks quantitatively good using these factors, so now we must take the analysis further.  Memory is a commodity.  It’s replaceable.  This industry can be easily disrupted.  It’s also vulnerable due to the decline of the PC.  Ultimately, I’d be speculating on their price going up short term, and long term, there’s no reason to guarantee they are going to steadily grow.
