It's unusual for me to go "big cap" but the stock is now *so* cheap and has so much great IP. The company is on a $1.20/share EPS run-rate which looks close to "trough" earnings to me, as here are the figures for the last five years:
The company also has approximately $1.50/share in net cash after accounting for the repatriation tax burden. So if you deduct $1.50 from $11.15 you get a net cost of $9.65/share, which is only 8x run-rate earnings and again, those earnings seem close to "trough."
Disclosure: I am long GLW.
