I woke up one morning 2 weeks ago to discover that a long-time holding, San Diego based CYMI, was quoted in the $70s per share, rather than ~$48/share. Thought it was a misprint. Then I discovered that Dutch-based ASML has proposed a cash/stock takeover. Impetus is CYMI's innovative extreme UV light technology used in the lithography for carving ever more narrow grooves in wafers used to make chips. That takeover is a surprise to me as I had always thought that AMAT would be a likely purchaser, if any entity. It certainly did not hurt overall portfolio value.
CYMI's technology had always been licensed world-wide.
Sounds like Moore's law continues to survive, one way or another.
